mariadb-connector-odbc-usage

MariaDB-specific behavior of MariaDB Connector/ODBC (the ODBC 3.8-compliant driver built on MariaDB Connector/C) for application code — that the DSN-less keyword is DRIVER={MariaDB ODBC 3.2 Driver} on Windows, or a registered driver name / .so path on Linux and macOS; that parameter markers are always the positional ? via SQLBindParameter, never named; that one Unicode (SQLWCHAR) driver binary serves both ANSI and Unicode apps via SQL_ATTR_ANSI_APP; that SQLPrepare+SQLExecute uses server-side prepared statements (binary protocol) while SQLExecDirect defaults to client-side text unless EDSERVER is set; that autocommit is ON by default so transactional code must switch SQL_ATTR_AUTOCOMMIT off; and that TLS turns on implicitly when any of SSLCA/SSLCERT/SSLKEY is set. Use when writing or reviewing application code (C/C++, or via a wrapper like pyodbc) that talks to MariaDB through the ODBC API.
