KILLALL QUERIES

On this page

The KILLALL QUERIES command kills all running queries or closes all connections.

Syntax

KILLALL [CONNECTIONS | QUERIES] [LIKE 'pattern']

Remarks

  • KILLALL CONNECTIONS will disconnect the clients associated with killed queries. This is the default.

  • KILLALL QUERIES will not disconnect the clients associated with killed queries. An error will be sent to all such clients.

  • pattern - Only kill queries which match this pattern.

  • KILLALL will only kill queries running on the same node as this operation.

  • SingleStore Helios checks for the kill bit during any potentially long running loop during query execution and rolls back the query’s transaction if the kill bit is set.

  • This command will only kill queries running on the same node as it.

Example

KILLALL QUERIES LIKE 'SELECT%';
Query OK, 0 rows affected (0.00 sec)
