在查询中调用存储过程

Question

我想在查询中调用我的sp，但是有2个错误：

Msg 156, Level 15, State 1, Line 17
Incorrect syntax near the keyword 'EXEC'.

Msg 156, Level 15, State 1, Line 19
Incorrect syntax near the keyword 'AS'.

这是我的查询：

    SELECT O.OrderId
  ,O.Number
  ,O.Creation
  ,(SELECT Name + ' ' + Surname FROM [User] WHERE UserId = (SELECT CreatedBy FROM [User] WHERE UserId = O.UserId) ) AS OrderOwner
  ,(SELECT Name + ' ' + Surname FROM [User] WHERE UserId = O.UserId )AS Customer
  ,(SELECT Telephone1 FROM [User]  WHERE UserId =  O.UserId) AS Telephone
  ,(SELECT CASE IsActive WHEN 1 THEN 'Indirimli' WHEN 0 THEN 'Indirimsiz' END AS Indirim FROM [User] WHERE UserId = O.UserId) AS Discount
  ,(SELECT CASE IsActive
     WHEN 0
     THEN 

         (SELECT SUM(Price) FROM Product WHERE ProductId IN( SELECT ProductId FROM OrderProduct WHERE OrderId = O.OrderId )) 
    WHEN 1
    THEN
    EXEC USP_CalculatePrice 70

    END AS Price
   FROM [User] WHERE UserId = O.UserID) AS Price

  ,O.Description
  ,O.Status 
  FROM
  [Order] AS O
  WHERE O.Status = 0

你有什么建议吗？

您不能在现有的select语句中调用存储过程。 您需要的是用户定义的标量函数 （与表函数或内置函数相对）。

根据您实际要执行的操作，可以应用用户定义的表函数。 在这种情况下，您将创建一个返回表的函数，然后可以联接到该表。 它们有点像视图，但是接受参数。
