Dear MySQL users,
MySQL Connector/Python v1.0.5 is a new version of the pure Python
database driver for MySQL. This is the first in a series of beta
releases that will introduce users to new features and changes.
This release is feature complete, but as a non-GA release is not
recommended for use in production environments. MySQL Connector/Python
version 1.0 is compatible with MySQL Server versions 5.5 and greater,
but should work with earlier versions (greater than v4.1).
MySQL Connector/Python v1.0.5 (beta) is available for download from
(Note: not all mirrors may be up to date yet)
A brief summary of changes in MySQL Connector/Python v1.0 is listed
below. Please check the ChangeLog file inside the distribution for a
more complete list of changes.
Changes in MySQL Connector/Python v1.0.5
This section documents changes and Bug fixes that have been applied
in MySQL Connector/Python since the development release v0.3.2.
Functionality Added or Changed:
* Adding support for time values with a fractional seconds part. A
new example script microseconds.py was added to show this
* Refactored the modules connection and protocol and created a new
module network. The MySQLProtocol does not keep a reference to the
connection object any more and deals only with creating and parsing
MySQL packets. Network interaction is now done by the
MySQLConnection objects (with the exception of
* Added MySQLConnection.reconnect() which used to reconnect to the
MySQL server. It accepts number of retries and a delay between
* Added descriptive error codes for both client and server errors in
the module errorcode. A new sub-package locales has been added,
which currently only support English client error messages.
* Added SQLMode class in the constants module, making it easier to use
* Incompatible Change: The MySQLConnection.ping() method raises an
InterfaceError when the MySQL server is not available. It can also
optinally reconnect and accepts the same arguments as the
* Incompatible Change: The MySQLConnection.is_connect() method now
returns True or False. It can be used to simply check whether a
connection is available or not.
* Incompatible Change: MySQLCursor.execute() does not return anything
for single statement operations. Sending multiple statements will
result in a generator object to be returned by
MySQLCursor.execute(). The MySQLCursor.next_resultset() became
obsolete and was removed and the MySQLCursor.next_proc_result()
method has been renamed to MySQLCursor.proc_results(), which
returns a generator object. The MySQLCursor.with_rows property can
be used to check if a result could return rows. The
multiple_resultset.py example script shows how to go through
results produced by sending multiple statements. (Bug #14208326)
* Incompatible Change: The method MySQLConnection.set_charset() has
been removed and replaced by MySQLConnection.set_charset_collation()
to simplify setting and retrieving character set and collation
information. The MySQLConnection properties collation and charset
are now read-only. (Bug #14260052)
* Incompatible Change: The MySQLConnection methods unset_client_flag()
and set_client_flag() have been removed. Use the set_client_flags()
method instead using a sequence. (Bug #14259996)
* Fixed MySQLCursor.executemany() when INSERT statements use the
'ON DUPLICATE KEY'-clause with a function like VALUES().
(Bug #14259954, Bug #65678)
* Fixed cursor.CursorBase attributes description, lastrowid and
rowcount to be read-only properties. (Bug #14231160)
* Fixed and refactored mysql.connector.errors module. (Bug #14039339)
* Fixed MySQLCursor.description so column names are Unicode.
* Fixed automatic garbage collection which caused memory usage to grow
over time. (Bug #13435186)
* Fixed setting time zone for current MySQL session. (Bug #13395083)
* Fixed handling of errors after authentication for Python v3.
The documentation is still being developed, and is included in the
distribution under the docs/ folder.
