这篇文章主要介绍了PostgreSQL查看正在执行的任务并强制结束的操作方法,本文给大家介绍的非常详细,对大家的学习或工作具有一定的参考借鉴价值,需要的朋友可以参考下。
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 <> '<IDLE>'
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';
