分割字符串查询
另换帖子了，问题不是简单的一说，试过几种方法，split charindex 貌似都达不到效果
测试数据

SQL code

insert into demoselect 3,'aa','1001' union all select 4,'bb','2001' union allselect 5, 'cc','3001' union allselect 6, '分类1','4001' union allselect 7, '分类2','5001' union allselect 8,'分类','2002'

查询条件declare @str='分类,2' 字段name和code like @str

查询结果应该是
id name code
----------- -------------------- --------------------
4 bb 2001
6 分类1 4001
7 分类2 5001
8 分类 2002
