根據用戶定義的變量選擇語句

Question

我想根據用戶的輸入（SSRS）做一個簡單的選擇語句。幫幫我！

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; 

預先感謝您

Answer 1

應該爲

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

順便說那樣簡單，SELECT *是非常糟糕的編碼，你真的應該指定每一列你正在返回。
