SQL Server 2005的存储过程的问题

Question

我写一个存储过程是这样的：

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 

我的问题是通过2个或多个值(select AccountNumber from tblInvAccountDetails where AccountTypeID = 10 and 20)所以我会比较子查询都accountnumbers (1000, 10003, 1006)基于AccountTypeID = 10 and 20

如何我可以写存储过程吗？

谢谢

Answer 1

使用IN没有=

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

注：

• AccountTypeID不能同时10和20在同一时间：我想你意味着或。 IN是多个手术室
• 的简写，其优先级，如果你需要(和)地方
