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;
