MySQL:返回更新的行 [英] MySQL: return updated rows

问题描述

我正在尝试在扭曲的python中合并这两个查询:

I am trying to combine these two queries in twisted python:

SELECT * FROM table WHERE group_id = 1013 and time > 100;

和:

UPDATE table SET time = 0 WHERE group_id = 1013 and time > 100

进入单个查询.有可能这样做吗?

into a single query. Is it possible to do so?

我尝试将SELECT放在子查询中，但我不认为整个查询都会返回我想要的内容.

I tried putting the SELECT in a sub query, but I don't think the whole query returns me what I want.

有没有办法做到这一点? (甚至更好，没有子查询) 还是我只需要坚持两个查询?

Is there a way to do this? (even better, without a sub query) Or do I just have to stick with two queries?

谢谢

推荐答案

您不能直接合并这些查询.但是您可以编写一个存储过程来执行两个查询.例如:

You can't combine these queries directly. But you can write a stored procedure that executes both queries. example:

delimiter |
create procedure upd_select(IN group INT, IN time INT)
begin
    UPDATE table SET time = 0 WHERE group_id = @group and time > @time;
    SELECT * FROM table WHERE group_id = @group and time > @time;
end;
|
delimiter ;
