Introduction
This API has been defined to encourage similarity between the
Python modules that are used to access databases. By doing this,
we hope to achieve a consistency leading to more easily understood
modules, code that is generally more portable across databases,

turn it back on.
Database modules that do not support transactions should
implement this method with void functionality.
.rollback()

This method is optional since not all databases provide

In case a database does provide transactions this method

.callproc(procname[,parameters])
(This method is optional since not all databases provide
stored procedures. [3])
Call a stored database procedure with the given name. The
sequence of parameters must contain one entry for each
argument that the procedure expects. The result of the
call is returned as modified copy of the input
sequence. Input parameters are left untouched, output and
input/output parameters replaced with possibly new values.
The procedure may also provide a result set as
output. This must then be made available through the
standard fetchXXX() methods.
.close()
Close the cursor now (rather than whenever __del__ is
called). The cursor will be unusable from this point
forward; an Error (or subclass) exception will be raised
if any operation is attempted with the cursor.
.execute(operation[,parameters])
.execute(operation[,parameters])
Prepare and execute a database operation (query or
command). Parameters may be provided as sequence or
mapping and will be bound to variables in the operation.
Variables are specified in a database-specific notation
(see the module's paramstyle attribute for details). [5]
A reference to the operation will be retained by the
cursor. If the same operation object is passed in again,
then the cursor can optimize its behavior. This is most
effective for algorithms where the same operation is used,
but different parameters are bound to it (many times).
For maximum efficiency when reusing an operation, it is
best to use the setinputsizes() method to specify the
parameter types and sizes ahead of time. It is legal for
a parameter to not match the predefined information; the
implementation should compensate, possibly with a loss of
efficiency.
The parameters may also be specified as list of tuples to
e.g. insert multiple rows in a single operation, but this
kind of usage is depreciated: executemany() should be used
instead.
Return values are not defined.
.executemany(operation,seq_of_parameters)
.executemany(operation,seq_of_parameters)
Prepare a database operation (query or command) and then
execute it against all parameter sequences or mappings
found in the sequence seq_of_parameters.
Modules are free to implement this method using multiple
calls to the execute() method or by using array operations
to have the database process the sequence as a whole in
one call.
Use of this method for an operation which produces one or
more result sets constitutes undefined behavior, and the
implementation is permitted (but not required) to raise

Fetch the next row of a query result set, returning a

sequence is returned when no more rows are available.

An Error (or subclass) exception is raised if the previous
call to executeXXX() did not produce any result set or no

Note there are performance considerations involved with
the size parameter. For optimal performance, it is
usually best to use the arraysize attribute. If the size
parameter is used, then it is best for it to retain the
same value from one fetchmany() call to the next.
.fetchall()
.fetchall()
Fetch all (remaining) rows of a query result, returning
them as a sequence of sequences (e.g. a list of tuples).
Note that the cursor's arraysize attribute can affect the
performance of this operation.

call to executeXXX() did not produce any result set or no

.nextset()
.nextset()
(This method is optional since not all databases support
multiple result sets. [3])
This method will make the cursor skip to the next
available set, discarding any remaining rows from the
current set.
If there are no more sets, the method returns
None. Otherwise, it returns a true value and subsequent
calls to the fetch methods will return rows from the next
result set.
An Error (or subclass) exception is raised if the previous
call to executeXXX() did not produce any result set or no

.arraysize
This read/write attribute specifies the number of rows to
fetch at a time with fetchmany(). It defaults to 1 meaning
to fetch a single row at a time.

the fetchmany() method, but are free to interact with the

the implementation of executemany().

[3] If the database does not support the functionality required
by the method, the interface should throw an exception in
case the method is used.
The preferred approach is to not implement the method and
thus have Python generate an AttributeError in
case the method is requested. This allows the programmer to
check for database capabilities using the standard
hasattr() function.
For some dynamically configured interfaces it may not be
appropriate to require dynamically making the method
available. These interfaces should then raise a
NotSupportedError to indicate the non-ability
to perform the roll back when the method is invoked.
[4] a database interface may choose to support named cursors by
allowing a string argument to the method. This feature is
not part of the specification, since it complicates
semantics of the .fetchXXX() methods.
[5] The module will use the __getitem__ method of the parameters
object to map either positions (integers) or names (strings)
to parameter values. This allows for both sequences and
mappings to be used as input.
The term "bound" refers to the process of binding an input
value to a database execution buffer. In practical terms,
this means that the input value is directly used as a value
in the operation. The client should not be required to
"escape" the value so that it can be used -- the value
should be equal to the actual database value.
[6] Note that the interface may implement row fetching using
arrays and other optimizations. It is not
guaranteed that a call to this method will only move the
associated cursor forward by one row.
[7] The rowcount attribute may be coded in a way that updates
its value dynamically. This can be useful for databases that
return usable rowcount values only after the first call to

This recipe tries to focus attention on a way to generate SQL queries to
insert completely new objects inside a database. As you can see objects do
not know anything about the code that is handling them. We specify all the
fields that we need for each object through the persistent_fields dict.
The most important lines of this recipe are:
register_adapter(Album, ObjectMapper)
register_adapter(Order, ObjectMapper)
In these lines we notify the system that when we call adapt with an Album instance
as an argument we want it to istantiate ObjectMapper passing the Album instance
In these lines we notify the system that when we call adapt with an Album instance
as an argument we want it to istantiate ObjectMapper passing the Album instance
as argument (self.orig in the ObjectMapper class).
The output is something like this (for each call to generateInsert):
('INSERT INTO Album (album_id, binary_data, creation_time) VALUES
(%(album_id)s, %(binary_data)s, %(creation_time)s)',
{'binary_data': <read-only buffer for 0x402de070, ...>,
'creation_time': datetime.datetime(2004, 9, 10, 20, 48, 29, 633728),

'creation_time': datetime.datetime(2004, 9, 10, 20, 48, 29, 633728),
'album_id': 1}
