STOP_STATEMENT¶

STOP_STATEMENT stops or aborts an active statement.

To find a statement by ID, see SHOW_SERVER_STATUS and SHOW_CONNECTIONS.

Tip

Some DBMSs call this killing a session or terminating a job

Permissions¶

The role must have the SUPERUSER permissions.

Syntax¶

stop_statement_statement ::=
    SELECT STOP_STATEMENT(stmt_id)
    ;

stmt_id ::= bigint

Parameters¶

Parameter	Description
`stmt_id`	The statement ID to stop

Returns¶

This utility does not return any value, and always succeeds even if the statement does not exist, or has already stopped.

Notes¶

This utility always succeeds even if the statement does not exist, or has already stopped.

Examples¶

Using SHOW_CONNECTIONS to get statement IDs¶

Tip

Use SHOW_SERVER_STATUS to find statments from across the entire cluster, or SHOW_CONNECTIONS to show statements from the current worker the client is connected to.

t=> SELECT SHOW_CONNECTIONS();
ip           | conn_id | conn_start_time     | stmt_id | stmt_start_time     | stmt

The statement ID we’re interested in is 129. We can now stop this statement:

t=> SELECT STOP_STATEMENT(129)
executed
