Release date: 30 Aug 2022
This is a Stable (GA) release of MariaDB Connector/ODBC 3.1.
MariaDB Connector/ODBC 3.1.17 is built on top of MariaDB Connector/C v.3.3.2.
Result-set streaming feature has been added (ODBC-369)
When using it, an application cannot cache the entire result-set on the client side, but will fetch it from the server row by row
The feature is enabled with the connection string option: NO_CACHE or STREAMRS is the alias, alternatively bit 1048576 in the OPTION can be used
The feature only comes into action with SQL_CURSOR_FORWARD_ONLY cursors. It will be always used if combined with the FORWARDONLY connection string option, or OPTION's bit 2097152.
Some features cannot work in combination with this feature, and the error HY000 with the message "The requested operation is blocked by another streaming operation" will be thrown by the connector in such case.
No new query can be executed before the application finishes fetching the streamed result-set. In particular, positioned operation on open cursor cannot be performed, if streaming is used for the cursor. Thus not all existing application may use this new feature.
