This is a Stable (GA) release of MariaDB Connector/ODBC 3.2.

MariaDB Connector/ODBC 3.2.2 is built on top of MariaDB Connector/C v.3.4.0.

Notable Changes

  • ODBC-421 - The driver has been moved to use Connector/C 3.4 series driver. The most important change implied by that, is that certificate verification option(SSLVERIFY) is now by default on if encrypted connection is requested by the application.
  • ODBC-163 - Support of new C/C callback system for custom data type conversion. There are 2 types of callbacks - for parameters and result. Parameter callbacks are used for bulk operations and allow to minimize memory use required for data type conversions. Their use controlled by the connection string option PCALLBACK, which is on by default. The option to turn on result callbacks is RCALLBACK and it is off by default. Result callbacks are expected to make certain type conversions faster and also reduce memory use, as they can write directly to application buffers and not to allocate intermediate buffers required for conversion.
  • ODBC-410 - SQLForeignKeys performance optimization. The function could be noticeably slow in the case of big number of schemas in the database. The optimization makes it significantly faster in such case.

Bug Fixes

  • ODBC-399 - Executable Comment Syntax which results in empty command gives 'You have an error in your SQL syntax'
  • ODBC-403 - Setting query timeout could cause error with older server versions "Unknown system variable 'STATEMENT'"
  • ODBC-405 - can't read DECIMAL values : Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.
  • ODBC-418 - Widechar string data gets truncated if contains NULL character
