SQL語句作爲參數

Question

是否有可能在SQL中做類似的事情？

DECLARE @t Nvarchar(50) 

SET @t = 'SELECT * FROM KIN_PHON' 

execute @t --?? 

Answer 1

使用exec：

DECLARE @t Nvarchar(50) 
SET @t = 'SELECT * FROM KIN_PHON' 
exec (@t) 

或者與參數，sp_executesql：

declare @sql nvarchar(max) 
set @sql = 'select * from YourTable where ID = @ID' 
execute sp_executesql @sql, N'@ID int', @ID = 42;
