本篇文章小编给大家分享一下PostgreSQL查看正在执行的任务并强制结束操作方法代码,文章代码介绍的很详细,小编觉得挺不错的,现在分享给大家供大家参考,有需要的小伙伴们可以来看看。
查看任务sql语句:
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 <> '' ORDER BY lap DESC;
其中
procpid:进程id
start:进程开始时间
lap:经过时间
current_query:执行中的sql
强制停止某一个任务:
SELECT pg_cancel_backend(进程id);
补充:
SELECT pid, datname AS db, query_start AS start, now() - query_start AS lap, query FROM pg_stat_activity WHERE state <> 'idle' and query not like '%pg_stat_activity%' and (now() - query_start) > interval '10 seconds';
