Question

我想一次选择deptUserCount和childDeptCount。

ALTER PROCEDURE [dbo].[sp_dept_user_select]     
@dept_no        INT,
@company_no     INT

AS
BEGIN   
SET NOCOUNT ON;

SELECT
(   SELECT COUNT(U.user_no) 
    FROM [dbo].[tb_user] U WITH(NOLOCK)
    INNER JOIN [dbo].[tb_dept_user] DU WITH(NOLOCK)
    ON U.user_no = DU.user_no
    WHERE DU.dept_no = @dept_no
    AND U.company_no = @company_no
    AND U.user_level < 200
) AS deptUserCount

,(  WITH tblChild AS
    (
        SELECT dept_no, parent_dept_no, name
        FROM [dbo].[tb_dept] D WITH(NOLOCK)
        WHERE parent_dept_no = 2
        AND D.company_no = 1

        UNION ALL
        SELECT D.dept_no, D.parent_dept_no, D.name
        FROM [dbo].[tb_dept] D  WITH(NOLOCK)
        INNER JOIN tblChild  
        ON D.parent_dept_no = tblChild.dept_no
        WHERE D.company_no = 1
    )
    SELECT COUNT(D.dept_no)
    FROM [dbo].[tb_dept] D WITH(ROWLOCK)
    WHERE dept_no IN (SELECT dept_no FROM tblChild)
) AS childDeptCount

END

这是我现在编写的代码。但是WITH语句出现错误，提示

不正确的语法错误

我该如何解决该错误？还是我必须做一个单独的过程才能得到我想要的东西？

Answer 1

您应该尝试这样的事情

WITH 
deptUserCount AS (
   SELECT ...
),
tblChild AS (
   SELECT ...
   UNION ALL
   SELECT ... FROM tblChild ...
)
SELECT ...
FROM tblChild JOIN deptUserCount...

您可以尝试以下操作

with deptUserCount as
(   SELECT COUNT(U.user_no) as dptcount 
    FROM [dbo].[tb_user] U WITH(NOLOCK)
    INNER JOIN [dbo].[tb_dept_user] DU WITH(NOLOCK)
    ON U.user_no = DU.user_no
    WHERE DU.dept_no = @dept_no
    AND U.company_no = @company_no
    AND U.user_level < 200
) ,tblChild as
(
       SELECT dept_no, parent_dept_no, name
        FROM [dbo].[tb_dept] D WITH(NOLOCK)
        WHERE parent_dept_no = 2
        AND D.company_no = 1

        UNION ALL
        SELECT D.dept_no, D.parent_dept_no, D.name
        FROM [dbo].[tb_dept] D  WITH(NOLOCK)
        INNER JOIN tblChild  
        ON D.parent_dept_no = tblChild.dept_no
        WHERE D.company_no = 1
), childDeptCount as
(
SELECT COUNT(D.dept_no) as childdptCnt
FROM [dbo].[tb_dept] D WITH(ROWLOCK)
WHERE dept_no IN (SELECT dept_no FROM tblChild)
) select a.childdptCnt,b.dptcount  from childDeptCount a,deptUserCount  b

选择语句和WITH语句错误
