Parameters

Usage notes

To stop a query running against the MySQL server, use the mysql_rds_kill_query procedure and pass in the connection ID of the thread that is running the query. The procedure then terminates the connection.

To obtain the ID, query the MySQL INFORMATION_SCHEMA PROCESSLIST table or use the MySQL SHOW PROCESSLIST command. The value in the ID column from SHOW PROCESSLIST or SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST is the processID.
