D.6.3.1. Changes in MySQL Connector/J 3.1.15 (Not yet released)

Important change: Due to a number of issues with the use of server-side prepared statements, Connector/J 5.0.5 has disabled their use by default. The disabling of server-side prepared statements does not affect the operation of the connector in any way.

To enable server-side prepared statements you must add the following configuration property to your connector string:

useServerPrepStmts=true

The default value of this property is false (that is, Connector/J does not use server-side prepared statements).

Bugs fixed:

  • Specifying US-ASCII as the character set in a connection to a MySQL 4.1 or newer server does not map correctly. (Bug#24840)
