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)
