MySQL Connector/ODBC 8.0.12 has been released

Dear MySQL users,

MySQL Connector/ODBC 8.0.12 is the second version of the MySQL Connector/ODBC 8.0 series, the ODBC driver for the MySQL Server.

The available downloads include both a Unicode driver and an ANSI driver based on the same modern codebase. Please select the 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 server version from 5.5.

This release of the MySQL ODBC driver is conforming to the ODBC 3.8 specification. It contains implementations of key 3.8 features, including self-identification as a ODBC 3.8 driver, streaming of output parameters (supported for binary types only), and support of the SQL_ATTR_RESET_CONNECTION connection attribute (for the Unicode driver only).

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

Functionality Added or Changed

  • Several code issues identified by Fortify were corrected.
  • Refactored codebase to remove legacy code and implement general performance improvements. For example, unused ANSI data conversion code and legacy functions were removed. Example improvements affect bookmark handling for bulk operations, handling of memory buffers for prepared statements, and handling of session variables.
  • On Windows, 32-bit support was added and 32-bit binaries are now available.
  • An RPM package for installing ARM 64-bit (aarch64) binaries of Connector/ODBC on Oracle Linux 7 is now available in the MySQL Yum Repository and for direct download. Known Limitation for this ARM release: You must enable the Oracle Linux 7 Software Collections Repository (ol7_software_collections) to install this package, and must also adjust the libstdc++7 path. See Yum’s Platform Specific Notes ( for additional details.

Bugs Fixed

  • Added checks for unsupported functionality that return SQL_ERROR instead of SQL_SUCCESS, where the error message refers to the unsupported functionality. (Bug #28217387)
  • The data source dependent type’s name was not always returned. For example, the ODBC driver reported TEXT as the database type for TINYTEXT, MEDIUMTEXT, and LONGTEXT, and reported BLOB for TINYBLOB, MEDIUMBLOB, and LONGBLOB. (Bug #11761407, Bug #53900)
