Release date: 30 May 2025

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

MariaDB Connector/ODBC 3.2.6 is built on top of MariaDB Connector/C v.3.4.5.

Bug Fixes

• - Crash in SQLExecDirect on UPDATE statement with array of parameters

• - The destructor releasing server side prepared statement could throw and this exception would not be caught

• - MS Access won't work with the linked table if best row id is BIGINT

• - MS Access shows record with AUTO_INCREMENT primary key as #Deleted after insert that does not specify that field value

• - SQLExecDirect on array of parameters could issue multistatement query even if multistatement option had not been selected for the connection.

• - Multiple issues with current implementation of SQLCancel

• - SQLCancel could run on already dropped statement due to race condition

• - Possible crash in SQLCancelHandle

New Feature

• - Introduced option TRUNCDT to skip time truncation error. Setting it to non-zero value makes connector not to return error on date/time type parameter value truncation. These are when value for SQL_TIME contains fractional part, or for SQL_DATE contains non-zero time. In particular, that permits to insert value with fractional part into TIME field which in MariaDB can have fractional part as ODBC SQL_TIME type

This is a alpha release of MariaDB Connector/ODBC 3.2.

Do not use alpha releases in production!

MariaDB Connector/ODBC 3.2.0 is built on top of MariaDB Connector/C v.3.3.2, and contains all fixes and changes from MariaDB Connector/ODBC v.3.1.18

Notable Changes

• - SQLExecDirect ODBC API function now uses text protocol and client side prepared statements(CSPS). That can be automatically switched to use of binary protocol and server side prepared statement(SSPS) if necessary(for example for CALL statement). ODBC API function SQLPrepare uses by default SSPS, but it can switch to CSPS, for example in case of multistatement query. The connection string option PREPONCLIENT to use CSPS by default also in SQLPrepare has been added. In some cases driver will still revert to use of SSPS even if this option is selected. One example of such case is a request of resultset metadata before SQLExecute API function call.

• - parameter array operations are now optimized also for the case of text protocol and CSPS use. i.e. driver can construct batch of queries based on values in parameter arrays for sending it via text protocol. Sending parameter arrays via binary protocol is supported already in 3.1 version and is preferable way for this operation.

• - Cursor type now defaults to SQL_CURSOR_FORWARD_ONLY as it is required by specs. 3.1.x series has default cursor type SQL_CURSOR_STATIC

• : The connector ordered SQLStatistics results using the wrong columns. This could cause MS Access to pick the wrong column as a unique index.

Release date: 2 Apr 2014

MariaDB ODBC Driver 0.9.1 is a release. In general this means that there are no known serious bugs, except for those marked as feature requests, but we feel it needs further testing and development before we call it stable.

MariaDB ODBC Driver 0.9.1 is built on top of the MariaDB LPGL C Client library and uses the binary prepared statement protocol.

Please, note that a beta version is NOT the final version of the product and we do not guarantee an absence of errors that may disrupt the computer's operation system and/or result data loss. We recommend against use of any beta software in a critical, commercial or production environment. Implementation of beta software should be limited to experienced users only in a staging or test environment.

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

• - 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.

• - 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.

  • Result callbacks are designed to make certain types of conversions faster and also reduce memory use, as they can write directly to application buffers and do not allocate intermediate buffers normally required for conversion. The option to turn on result callbacks is RCALLBACK

• - SQLForeignKeys performance optimization. The function could be noticeably slow in the case of a large number of schemas in the database. The optimization makes it significantly faster in such cases.

Issues Fixed

• - Executable Comment Syntax which results in empty command gives 'You have an error in your SQL syntax'

• - Setting query timeout could cause error with older server versions "Unknown system variable 'STATEMENT'"

• - can't read DECIMAL values with error:

• - Widechar string data gets truncated if it contains a NULL character

Bug Fixes

• - Crash fetching from statement after closing and re-executing

• - C/ODBC binary tarball for RHEL/CentOS has duplicate libraries

Notable changes

• - Connector misses "interactive client" option. Added INTERACTIVE connection string option to tell server, that the client application is interactive, and interactive_timeout has to be used.

• - Add charsets recoding function to C/ODBC. Iconv-based conversion function has been moved and adapted from MariaDB Connector/C. It's the same function that was used before. The function is used only on platforms other than Windows.

Notable Changes

• - Added a connection string option to suppress errors on schema parameters in catalog functions.

  • Schema parameters used to be neglected by catalog functions, while the specification says the error has to be returned if those are provided and the driver does not support schemas. has changed that. Because this can break existing applications that misuse the API, the connection string option SCHEMANOERROR has been introduced to suppress these errors, if necessary.

This is an Alpha release of MariaDB Connector/ODBC 3.0.

As with any other pre-production release, caution should be taken when installing this alpha release on production systems or systems with critical data. Not all of the features planned for the stable (GA) MariaDB Connector/ODBC 3.0 release are implemented yet.

MariaDB Connector/ODBC 3.0.0 is built on top of MariaDB Connector/C 3.0 and uses the binary prepared statement protocol.

For SQLExecDirect calls, uses the mariadb_stmt_execute_direct MariaDB C API command, which is faster than using mysql_stmt_prepare + mysql_stmt_execute, but only with server.

This release was built with SSL support. You can use SSLKEY, SSLCERT, SSLCA, SSLCAPATH, SSLCIPHER, SSLVERIFY, SSLCRL and SSLCRLPATH connection string/DSN options to configure your connection properties.

Internally, Connector/ODBC 3.0 depends much less on Connector/C internal features than previous versions, with the eventual goal of only using the open Connector/C API.

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

MariaDB Connector/ODBC 2.0.11 is built on top of MariaDB Connector/C 2.2 and uses the binary prepared statement protocol.

Bug Fixes

• - incorrect binding of TIMESTAMP to TIME type. It would affect work with MS Access if table had time and auto_increment fields.

• - basically ensuring that the number of columns (counter in descriptor) is reset before issuing a new query.

• - SQLColumns (and some others along with it) returned ODBC3 SQL types, while MS Access is an ODBC2 application.

• - the variable used for length in bind structure in SQLGetData, was bigger than "unsigned long" on 64bit machines.

• Revision #08da03f 2023-06-10 21:58:33 +0200

  • Overriding the problem with c/c requires C99 with older GCC

• 2023-06-10 12:42:29 +0200

  • The fix and the testcase

• 2023-06-05 12:44:14 +0200

  • Only the fix as lower_case_table_names can't be changed for session. i.e. the test has been added, but to server has to be in lower_case_table_names=2 mode to test the fix, otherwise it ensures that the fix doesn't break catalog functions against server in "normaler" mode. The fix adds reading of the lower_case_table_names, and if it's 2, then it compares table name case insensitively where case sensitive comparison would be used otherwise. The problem actually affects not ony SQLStatistics, but almost all catalog functions, that take catalog and/or table parameter as ordinary argument.
