Question

我有一个存储过程，我想在SELECT中使用，但是我收到错误。

存储过程的输出是一个包含int

类型列的表

select * from users where resCode in (EXEC getUserResselers 1)

-- stored procedure
create procedure getUserResselers
    @userCode int
as
    ;WITH Directories AS (SELECT  code FROM Resseler WHERE code =(select resselerCode from Users where code=@userCode)
    UNION ALL SELECT d.code FROM Resseler d INNER JOIN Directories p ON  d.parent = p.code)
        SELECT  * FROM    Directories d

不支持从存储过程直接选择。但是，这种类型的操作是table-valued user-defined function的良好候选者，可能类似于：

^{请注意，您有拼写错误的“转销商”。我已经离开了拼写错误，以便您可以使用现有架构进行测试。}

CREATE FUNCTION getUserResselers
(
    @UserCode INT
)
RETURNS TABLE AS
RETURN(
    WITH Directories AS (

       SELECT  code FROM Reseller WHERE code = (select resselerCode from Users where code=@userCode)
       UNION ALL SELECT d.code FROM Resseler d INNER JOIN Directories p ON  d.parent = p.code
    )
    SELECT  * FROM   Directories
)

然后，您可以在查询中包含该功能的联接，或者您可以继续使用IN，这应该类似于：

select * from users where resCode in (SELECT Code FROM getUserResselers(1));

在选择查询中使用存储过程
