这篇文章主要介绍mysql实现行转列的方法，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

mysql实现行转列的方法：1、用cross join的方式实现，代码为【cross join(select sum(a.kills) '猪八戒】；2、用case语句的方式实现，代码为【case when user_name='孙悟空'】。

mysql实现行转列的方法：

1、用cross join的方式实现

select * from (select sum(a.kills) '孙悟空' from kills1 as a LEFT JOIN tssrz as b on a.user_id = b.id WHERE b.user_name = '孙悟空' GROUP BY b.user_name) e cross join (select sum(a.kills) '猪八戒' from kills1 as a LEFT JOIN tssrz as b on a.user_id = b.id WHERE b.user_name = '猪八戒' GROUP BY b.user_name) f

2、用case语句的方式实现

SELECT sum(case when user_name='孙悟空' then kills end) as '孙悟空', sum(case when user_name='猪八戒' then kills END) as '猪八戒', sum(case when user_name='沙和尚' then kills END) as '沙和尚' from tssrz as a join kills1 as b on a.id = b.user_id
