SHOW QUERIES

The SHOW QUERIES statement shows the information of working queries in the current session.

Note

To terminate queries, see Kill Query.

Precautions

  • The SHOW QUERIES statement gets the status of queries in the current session from the local cache with almost no latency.
  • The SHOW ALL QUERIES statement gets the information of queries in all the sessions from the Meta Service. The information will be synchronized to the Meta Service according to the interval defined by session_reclaim_interval_secs. Therefore the information that you get from the client may belong to the last synchronization interval.

Syntax

SHOW [ALL] QUERIES;
