SQL Server 2005的存儲過程的問題

Question

我寫一個存儲過程是這樣的：

create PROC uspInvCustomerLineItemGetList1(@CustomerID varchar(50)) 
AS 
BEGIN 
    SELECT LineItemID, LineItemName 
    from tblInvoiceLineItems 
    where CustomerID = @CustomerID 
     or CustomerID = '' 
     and AccountNumber = (select AccountNumber from tblInvAccountDetails 
          where AccountTypeID = 10 and 20) 

END 

我的問題是通過2個或多個值(select AccountNumber from tblInvAccountDetails where AccountTypeID = 10 and 20)所以我會比較子查詢都accountnumbers (1000, 10003, 1006)基於AccountTypeID = 10 and 20

如何我可以寫存儲過程嗎？

謝謝

Answer 1

使用IN沒有=

... 
where 
    CustomerID=@CustomerID 
    or 
    CustomerID='' 
    and 
    AccountNumber IN (select AccountNumber from tblInvAccountDetails where AccountTypeID IN (10, 20)) 

注：

• AccountTypeID不能同時10和20在同一時間：我想你意味着或。 IN是多個手術室
• 的簡寫，其優先級，如果你需要(和)地方
