MySQL Connector/ODBC 3.51.18 is available!

Dear MySQL users,

MySQL Connector/ODBC 3.51.18, a new version of the ODBC driver for the MySQL database system, has been released. This release is the latest release of the 3.51 series and is suitable for use with any MySQL version including MySQL 4.1, 5.0, or 5.1.

  WARNING   While we consider this a production release, we recommend caution in   upgrading due to changes in our build procedures, and the large number   of bug fixes that have gone into the most recent releases.

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

   http://dev.mysql.com/downloads/connector/odbc/3.51.html

and mirror sites. Note that not all mirror sites may be up to date at this point in time, so if you can't find this version on some mirror, please try again later or choose another download site.

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

Platform notes:
* There are no installer packages for Microsoft Windows x64 Edition. * There is no binary package for Mac OS X on 64-bit PowerPC because Apple   does not currently provide a 64-bit PowerPC version of iODBC. * The HP-UX 11.23 IA64 binary package does not include the GUI bits because   of problems building Qt on that platform.

Changes since the last release:

  Functionality added or changed:

• An experimental binary package, without an installer, is available for Microsoft Windows x64 Edition.
• Binary packages as disk images with installers are now available for Mac OS X.
• Binary packages for Sun Solaris are available as PKG packages.
• Added FLAG_MULTI_STATEMENTS to allow issuing queries that contain multiple statements. Also added to the setup GUI. (Bug #7445)
• Removed support for the TRACE and TRACEFILE DSN options. The standard ODBC logging should be used.
• Added support for SQL_ATTR_ROW_BIND_OFFSET_PTR in normal cursors. (Bug #6741)
• Added SSL options to the GUI setup dialog.

  Bugs fixed:

• SQLColumns() incorrectly reported that an auto-incrementing field was not nullable. (Bug #14407)
• SQLColumns() incorrectly reported that an auto-updating timestamp field was not nullable. (Bug #14414)
• Lengths returned by SQLColumns(), SQLDescribeCol(), and SQLColAttribute() were often incorrect. These lengths should now conform to the ODBC specification. FLAG_FIELD_LENGTH no longer has any effect. The default behavior was incorrect. (Bug #27862)
• The SQL_DATA_TYPE column in SQLColumns() results did not report the correct value for date and time types.
• The SQL_DATETIME_SUB column in SQLColumns() was not correctly set for date and time types.
• The value for SQL_DESC_FIXED_PREC_SCALE was not returned correctly for decimal values in MySQL 5.0 and later.
• The wrong value from SQL_DESC_LITERAL_SUFFIX was returned for binary fields.
• The wrong value for SQL_DESC_TYPE was returned for date and time types.
• The wrong value for DECIMAL_DIGITS in SQLColumns() was reported for FLOAT and DOUBLE fields, as well as the wrong value for the scale parameter to SQLDescribeCol(), and the SQL_DESC_SCALE attribute from SQLColAttribute().
• MySQL BIT(n) fields were always treated as SQL_BIT data. When n > 1, they are now treated as binary data.
• If the connection character set was set to a multibyte character set, such as UTF-8, the wrong column size was reported. (Bug #19345)
• SQLSpecialColumns() returned all TIMESTAMP fields when queried for SQL_ROWVER, not just an auto-updating TIMESTAMP field. (Bug #9927, still limited by Bug #30081 in the server.)
• SQLConnect() and SQLDriverConnect() were rewritten to eliminate duplicate code and ensure all options were supported using both connection methods. SQLDriverConnect() now only requires the setup library to be present when the call requires it.
• SQLColumns() failed when a catalog was specified due to an incorrectly-generated query. (Bug #29888)
• SQLGetTypeInfo() returned incorrect information for date and time fields, and would not return results when queried for the SQL_DATETIME type. (Bug #28657)
• myodbc3i did not honor the 's' and 'u' modifier to the -d option for installing the driver as a system or user driver. (Bug #29964)
• Tables from the mysql database (catalog) were listed as SYSTEM TABLES by SQLTables() even when a different catalog was being queried. This also introduced errors due to the fix for Bug #26934. (Bug #28662)

Enjoy!
