Ending a session or query

The following stored procedures end a session or query.

mysql.rds_kill

Ends a connection to the MySQL server.

Syntax

CALL mysql.rds_kill(processID);

Parameters

processID

The identity of the connection thread to be ended.

Usage notes

Each connection to the MySQL server runs in a separate thread. To end a connection, use the mysql.rds_kill procedure and pass in the thread ID of that connection. To obtain the thread ID, use the MySQL SHOW PROCESSLIST command.

For information about limitations, see MySQL stored procedure limitations.

Examples

The following example ends a connection with a thread ID of 4243:

CALL mysql.rds_kill(4243);

mysql.rds_kill_query

Ends a query running against the MySQL server.

Syntax

CALL mysql.rds_kill_query(processID);

Parameters

processID

The identity of the process or thread that is running the query to be ended.

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.

For information about limitations, see MySQL stored procedure limitations.

Examples

The following example stops a query with a query thread ID of 230040:

CALL mysql.rds_kill_query(230040);
