问题描述

我可以在MySQL INSERT查询上使用LIMIT 2吗?例如

Can i use LIMIT 2 on MySQL INSERT query? e.g.

INSERT INTO MyTable
   (user_name,password)
VALUES
   (john,366543),
   (sam,654654)
LIMIT 2

我尝试了它的谚语

`#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'LIMIT 2' at line 1`

推荐答案

您可以使用插入...选择语法:

INSERT INTO MyTable (user_name, password)
SELECT 'john', '366543'
UNION ALL SELECT 'sam', '654654'
LIMIT 2;

不知道为什么要...可能想通过设置限制轻松控制一长串静态值?

Not sure why you would want to... maybe if you had a very long list of static values that you wanted to easily control by setting the limit?

正如pst所指出的，LIMIT实际上是SELECT的一部分，与INSERT本身无关...

As pst notes, the LIMIT is actually part of the SELECT, and has nothing to do with the INSERT itself...
