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

• MariaDB Connector/ODBC 3.2.5 is built on top of MariaDB Connector/C v.3.4.4.

Notable Changes

MariaDB ODBC drivers of 3.2 series can use both text and binary protocol, i.e. prepare statements on the client or on the server side, with text protocol being the default for direct execution(SQLExecDirect() function) and binary protocol for prepared statements(SQLPrepare()+SQLExecute() functions). This release provides applications more control on what protocol to be used

• ODBC-451 - Introduced connection string option EDSERVER to force SQLExecDirect to use server side prepared statements(SSPS)/binary protocol. This option compliments introduced earlier PREPONCLIENT option making SQLPrepare+SQLExecute to prepare query on the client side

• ODBC-452 - Added statement and connection attributes to control where queries are prepared by SQLExecDirect and SQLPrepare. These attributes are MariaDB specific, i.e. they will be ignored by other ODBC drivers. The attribute type values are SQL_ATTR_EXECDIRECT_ON_SERVER=25100 and SQL_ATTR_PREPARE_ON_CLIENT=25101. Setting of connection attributes are equivalent of using of connection string options mentioned above. Statement attributes allow to do the same at the statement level.
