Functionality Added or Changed
Incompatible Change: Python 2 code was changed to use new features introduced in Python 2.6 and 2.7. Some examples:
print() is used as a function, not a
Exceptions are handled using the
in keyword is used instead of the
has_key() dictionary method.
This change means that MySQL Connector/Python 1.1 does not work with versions of Python older than 2.6.
Connector/Python was updated with error information from MySQL 5.7.1. (Bug #16896702)
MySQLConnection objects now support an
in_transaction property that returns
False to indicate
whether a transaction is active for the connection.
Connector/Python supports a new
MySQLCursorPrepared class that enables
execution of prepared SQL statements using the binary
client/server protocol. For details, see
MySQLConnection objects now support a
start_transaction() method to begin a
transaction. This method accepts arguments indicating whether to
use a consistent snapshot and which transaction isolation level
consistent_snapshot value is
False. The default
isolation_level value is
None, and permitted values are
'REPEATABLE READ', and
mysql.connector.__version_info__ now are
available to provide MySQL Connector/Python version information
in a more standard, Pythonic manner.
Relative imports were removed from Python 3 code. PEP-8 indicates that relative imports are discouraged. (Bug #16234372)
