sql - 根据用户定义的变量选择语句

Question

我正在尝试根据用户的输入（SSRS）做一个简单的选择语句。帮助！

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;

先感谢您

Answer 1

它应该像这样简单

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

顺便说一句，SELECT *编码真的很糟糕，你真的应该指定你要返回的每一列。
