根据用户定义的变量选择语句

Question

我想根据用户的输入（SSRS）做一个简单的选择语句。帮帮我！

select * from Table1 
WHERE 
Case when @x = 'Yes' then (select * from Table1 where [Column1] < 0) end; 
case when @x = 'No' then (select * from Table1 where [Column1] > 0) end; 

预先感谢您

Answer 1

应该为

select * from Table1 
WHERE 
(@x = 'Yes' AND [Column1] < 0) 
OR 
(@x = 'No' AND [Column1] > 0); 

顺便说那样简单，SELECT *是非常糟糕的编码，你真的应该指定每一列你正在返回。
