Changes in MySQL Connector/ODBC 5.3.9 (2017-07-24, General

Functionality Added or Changed

  • When compiling Connector/ODBC on Windows platforms, it can now be linked statically (equivalent to the /MT compiler option in Visual Studio) or dynamically (equivalent to the /MD compiler option in Visual Studio) to the Visual C++ runtime. The default option is to link dynamically; if you want to link statically. set the new CMake option, STATIC_MSVCRT, to true. Another new CMake option, WITH_NODEFAULTLIB, has been introduced for specifying the Visual C++ runtime you want to link Connector/ODBC to when using mixed link types (that is, when link type to the Visual C++ runtime differs for Connector/ODBC and the MySQL client library it links to). See Building Connector/ODBC from a Source Distribution on Windows( for details.

Bugs Fixed

  • The SQLForeignKeys() function returned an empty result set when the information schema was being used. (Bug #26388694)
  • Calling SQLExecute() after calling SQLFreeStmt() with the SQL_RESET_PARAMS option resulted in an assertion failure. With this fix, a proper error is now thrown in the situation. (Bug #19148246)
  • A segmentation fault occurred in SQLFetch() when SQL_ATTR_CURSOR_TYPE was set to SQL_CURSOR_DYNAMIC. (Bug #18805392)
  • Connector/ODBC quit unexpectedly in SQLForeignKeys() when SQL_MODE was set to ANSI_QUOTES. (Bug #18641824)
