PostgreSQL列举和停止执行中的sql
PostgreSQL列举正在执行中的sql
- SELECT
- procpid,
- start,
- now() - start AS lap,
- current_query
- FROM
- (SELECT
- backendid,
- pg_stat_get_backend_pid(S.backendid) AS procpid,
- pg_stat_get_backend_activity_start(S.backendid) AS start,
- pg_stat_get_backend_activity(S.backendid) AS current_query
- FROM
- (SELECT pg_stat_get_backend_idset() AS backendid) AS S
- ) AS S
- WHERE
- current_query <> '<IDLE>'
- ORDER BY
- lap DESC;
procpid:进程id
start:进程开始时间
lap:经过时间
current_query:执行中的sql
怎样停止正在执行的sql
SELECT pg_cancel_backend(进程id);
或者用系统函数
kill -9 进程id;
