我需要正确地遵循sql脚本语法.在postgres中,你不能真正将“alter sequence”与“select max(id)”链接起来.那么以Postgresql接受它的方式编写脚本的正确方法是什么？ @H_403_9@

@H_403_9@这是脚本,所以你可以知道我需要什么：

@H_403_9@

alter SEQUENCE notification_settings_seq START with (select max(id) from game_user)

do $$
declare maxid int;
begin
    select max(id) from game_user into maxid;
    execute 'alter SEQUENCE seq_name RESTART with '|| maxid;   
end;
$$language plpgsql
