我有表T1
列ID1
,ID2
。SQL Server:選擇「值或全部」
我需要寫一個「選擇」存儲過程是這樣
Create SP_GetT1ByID1AndID2
@id1 varchar(50), @id2 varchar(50)
as
begin
Select *
from T1
where
// If (ID1 = "All" and ID2 = "All") so we have to return all the data in the table T1
// If (ID1 = "All" and ID2 != "All") so we have filter the data according to ID2
// If (ID1 != "All" and ID2 = "All") so we have filter the data according to ID1
// If (ID1 != "All" and ID2 != "All") so we have filter the data according to ID1 and ID2
end
旁註:你應該** **不使用'sp_'前綴爲您的存儲過程。微軟[留作自己使用前綴(見*命名存儲過程*)(http://msdn.microsoft.com/en-us/library/ms190669%28v=sql.105%29.aspx),和你將來有可能冒着名字衝突的風險。 [這對你的存儲過程性能也是不利的](http://www.sqlperformance.com/2012/10/t-sql-queries/sp_prefix)。最好只是簡單地避免使用'sp_'並將其他內容用作前綴 - 或者根本沒有前綴! –
