class BaseCursor(__builtin__.object) |

A base for Cursor classes. Useful attributes:
description
A tuple of DB API 7-tuples describing the columns in
the last executed query; see PEP-249 for details.
description_flags
Tuple of column flags for last query, one entry per column
in the result set. Values correspond to those in
MySQLdb.constants.FLAG. See MySQL documentation (C API)
for more information. Non-standard extension.
arraysize
default number of rows fetchmany() will fetch

Methods defined here:
- __del__(self)
- __init__(self, connection)
- __iter__(self)
- callproc(self, procname, args=())
- Execute stored procedure procname with args
procname -- string, name of procedure to execute on server
args -- Sequence of parameters to use with procedure
Returns the original args.
Compatibility warning: PEP-249 specifies that any modified
parameters must be returned. This is currently impossible
as they are only available by storing them in a server
variable and then retrieved by a query. Since stored
procedures return zero or more result sets, there is no
reliable way to get at OUT or INOUT parameters via callproc.
The server variables are named @_procname_n, where procname
is the parameter above and n is the position of the parameter
(from zero). Once all result sets generated by the procedure
have been fetched, you can issue a SELECT @_procname_0, ...
query using .execute() to get any OUT or INOUT values.
Compatibility warning: The act of calling a stored procedure
itself creates an empty result set. This appears after any
result sets generated by the procedure. This is non-standard
behavior with respect to the DB-API. Be sure to use nextset()
to advance through all result sets; otherwise you may get
disconnected.
- close(self)
- Close the cursor. No further queries will be possible.
- execute(self, query, args=None)
- Execute a query.
query -- string, query to execute on server
args -- optional sequence or mapping, parameters to use with query.
Note: If args is a sequence, then %s must be used as the
parameter placeholder in the query. If a mapping is used,
%(key)s must be used as the placeholder.
Returns long integer rows affected, if any
- executemany(self, query, args)
- Execute a multi-row query.
query -- string, query to execute on server
args
Sequence of sequences or mappings, parameters to use with
query.
Returns long integer rows affected, if any.
This method improves performance on multiple-row INSERT and
REPLACE. Otherwise it is equivalent to looping over args with
execute().
- nextset(self)
- Advance to the next result set.
Returns None if there are no more result sets.
- setinputsizes(self, *args)
- Does nothing, required by DB API.
- setoutputsizes(self, *args)
- Does nothing, required by DB API.

error occurred during processing, etc.

query -- string, query to execute on server
args -- optional sequence or mapping, parameters to use with query.
Note: If args is a sequence, then %s must be used as the
parameter placeholder in the query. If a mapping is used,
%(key)s must be used as the placeholder.
Returns long integer rows affected, if any
- executemany(self, query, args)
- Execute a multi-row query.
query -- string, query to execute on server
args
Sequence of sequences or mappings, parameters to use with
query.
Returns long integer rows affected, if any.
This method improves performance on multiple-row INSERT and
REPLACE. Otherwise it is equivalent to looping over args with
execute().
- nextset(self)
- Advance to the next result set.
Returns None if there are no more result sets.
- setinputsizes(self, *args)
- Does nothing, required by DB API.
- setoutputsizes(self, *args)
- Does nothing, required by DB API.
Data and other attributes inherited from BaseCursor:
- DataError = <class _mysql_exceptions.DataError>
- Exception raised for errors that are due to problems with the
processed data like division by zero, numeric value out of range,
etc.
- DatabaseError = <class _mysql_exceptions.DatabaseError>
- Exception raised for errors that are related to the
database.
- Error = <class _mysql_exceptions.Error>
- Exception that is the base class of all other error exceptions
(not Warning).
- IntegrityError = <class _mysql_exceptions.IntegrityError>
- Exception raised when the relational integrity of the database
is affected, e.g. a foreign key check fails, duplicate key,
etc.
- InterfaceError = <class _mysql_exceptions.InterfaceError>
- Exception raised for errors that are related to the database
interface rather than the database itself.
- InternalError = <class _mysql_exceptions.InternalError>
- Exception raised when the database encounters an internal
error, e.g. the cursor is not valid anymore, the transaction is
out of sync, etc.
- MySQLError = <class _mysql_exceptions.MySQLError>
- Exception related to operation with MySQL.
- NotSupportedError = <class _mysql_exceptions.NotSupportedError>
- Exception raised in case a method or database API was used
which is not supported by the database, e.g. requesting a
.rollback() on a connection that does not support transaction or
has transactions turned off.
- OperationalError = <class _mysql_exceptions.OperationalError>
- Exception raised for errors that are related to the database's
operation and not necessarily under the control of the programmer,
e.g. an unexpected disconnect occurs, the data source name is not
found, a transaction could not be processed, a memory allocation
error occurred during processing, etc.
- ProgrammingError = <class _mysql_exceptions.ProgrammingError>
- Exception raised for programming errors, e.g. table not found
or already exists, syntax error in the SQL statement, wrong number
of parameters specified, etc.
- Warning = <class _mysql_exceptions.Warning>
- Exception raised for important warnings like data truncations
