Dear MySQL users,

MySQL Connector/ODBC 5.2.3, a new version of the ODBC driver for the
MySQL database management system, has been released.

The available downloads include both a Unicode driver and an ANSI
driver based on the same modern codebase. Please select driver type
you need based on the type of your application - Unicode or ANSI.
Server-side prepared statements are enabled by default. It is suitable
for use with any MySQL version since 4.1 (It will not work with 4.0 or
earlier releases.)

The release is now available in source and binary form for a number of
platforms from our download pages at

For information on installing, please see the documentation at

We welcome and appreciate your feedback, bug reports, bug fixes,
patches, etc.:


The MySQL build team at Oracle


Bugs Fixed

  * Insert operations could fail if the inserted values contained
    any bit fields, mapped to table columns declared as bit(1):

      Data too long for column 'column_name'

    (Bug #15997361, Bug #67702)

  * The is_minimum_version function could return an incorrect
    result in some cases where the difference was in the third
    component of the release number. (Bug #15926340)

  * An application making extensive use of prepared statements
    could encounter an error:

      Can't create more than max_prepared_stmt_count statements
      (current value: 16382)

    The issue occurred even if SQLFreeStmt() calls were used. The
    Prepared_stmt_count value grew until it exceeded the internal
    limit. A workaround was to disable server-side prepared
    statements. (Bug #14812778, Bug #67340)

  * On a 64-bit system, calls to the SQLBindCol function using
    indicator variables (through the last parameter) could return
    incorrect results. (Bug #11766437, Bug #59541)

Built against the MySQL server 5.5.27 client library.
