MySQL在每行唯一的一个查询条件中删除多行 [英] MySQL delete multiple rows in one query conditions unique to each row

问题描述

所以我知道在 MySQL 中，可以在一个查询中插入多个行，如下所示:

So I know in MySQL it's possible to insert multiple rows in one query like so:

INSERT INTO table (col1,col2) VALUES (1,2),(3,4),(5,6)

我想以类似的方式删除多行.我知道可以根据每一行的完全相同条件删除多行，即

I would like to delete multiple rows in a similar way. I know it's possible to delete multiple rows based on the exact same conditions for each row, i.e.

DELETE FROM table WHERE col1='4' and col2='5'

或

DELETE FROM table WHERE col1 IN (1,2,3,4,5)

但是，如果我想在一个查询中删除多行，而每一行都有一组唯一的条件，该怎么办?这样的东西就是我想要的东西:

However, what if I wanted to delete multiple rows in one query, with each row having a set of conditions unique to itself? Something like this would be what I am looking for:

DELETE FROM table WHERE (col1,col2) IN (1,2),(3,4),(5,6)

有人知道这样做的方法吗?还是不可能?

Does anyone know of a way to do this? Or is it not possible?

推荐答案

您非常亲密，可以使用此功能:

You were very close, you can use this:

DELETE FROM table WHERE (col1,col2) IN ((1,2),(3,4),(5,6))
