修改为指定值
DO $$DECLARE r record; BEGIN FOR r IN SELECT sequence_name FROM information_schema."sequences" LOOP EXECUTE 'ALTER SEQUENCE '|| r.sequence_name ||' restart WITH 10000'; END LOOP; END$$;
根据表的id修改
DO $$ DECLARE r record; start_value integer := 0; BEGIN FOR r IN SELECT tablename||'_id_seq' AS sequence_name, tablename FROM pg_tables WHERE schemaname = 'public' LOOP EXECUTE 'SELECT max(id)+1 AS max_value FROM ' || r.tablename INTO start_value; IF start_value IS NULL THEN start_value:= 1; END IF; RAISE NOTICE 'start_value % %', r.tablename,start_value; EXECUTE 'ALTER SEQUENCE '|| r.sequence_name ||' restart WITH ' || start_value; END LOOP; END$$;
补充:postgresql 13 数据库 sequence 的 maxvalue 最大值是多少"htmlcode">
那就需要查看下 bigint 的值 以上为个人经验,希望能给大家一个参考,也希望大家多多支持。如有错误或未考虑完全的地方,望不吝赐教。

maxvalue
NO MAXVALUE
The optional clause MAXVALUE maxvalue determines the maximum value for the sequence. If this clause is not supplied or NO MAXVALUE is specified, then default values will be used. The default for an ascending sequence is the maximum value of the data type. The default for a descending sequence is -1.

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
