Dear MySQL users,
MySQL Connector/Python 2.2.3 M4 is the fourth development release of the
MySQL Connector Python 2.2 series. This series adds support for the new
X DevAPI. The X DevAPI enables application developers to write code that
combines the strengths of the relational and document models using a
modern, NoSQL-like syntax that does not assume previous experience
writing traditional SQL.
To learn more about how to write applications using the X DevAPI, see
http://dev.mysql.com/doc/x-devapi-userguide/en/. For more information
about how the X DevAPI is implemented in MySQL Connector/Python, and its
usage, see http://dev.mysql.com/doc/dev/connector-python.
Please note that the X DevAPI requires MySQL Server version
5.7.12 or higher with the X Plugin enabled. For general documentation
about how to get started using MySQL as a document store, see
http://dev.mysql.com/doc/refman/5.7/en/document-store.html.
To download MySQL Connector/Python 2.2.3 M4, see the "Development
Releases" tab at http://dev.mysql.com/downloads/connector/python/
Enjoy!
Changes in MySQL Connector/Python 2.2.3 (2017-03-22, Milestone 4)
Functionality Added or Changed
* Connector/Python now supports IPv6 target hosts in X
DevAPI connection strings.
Bugs Fixed
* The defined_as(statement) method used to create views did
not permit a SelectStatement object argument (generated
by Table.select()). (Bug #25614860)
* The SelectStatement object returned by Table.select()
failed to provide the order_by() method. (Bug #25519251)
* The pure Python implemention of Protobuf has been
replaced by a C++ extension. This enables
Connector/Python to support Python 2 and 3 as well as
Protobuf 2 and 3. (Bug #25209469)
* import mysqlx caused an error with Python 2.6 on Solaris
and EL6 platforms. (Bug #24578507)
* The error message for get_session() failure was
incorrect. (Bug #23636962)
* The Collection.find() method failed to work with the LIKE
operator or aggregate functions.
The Collection.find() method failed to work with several
operators. Support was added for these operators:
+ Nullary Operators:
*
+ Unary Operators:
!, NOT, +, -, ~
+ Binary Operators:
AND, &&, OR, ||, XOR, <>, ^
IS NOT, NOT REGEXP, NOT LIKE, CAST, NOT IN
+ Ternary Operators:
NOT BETWEEN
In addition, arrow notation to access JSON columns is now
functional (for example, schema.table.column->'$.document
field'). (Bug #23567724, Bug #23568207, Bug #25436568,
Bug #84585)
