Question

我有一个返回itemcodes集的函数。结果是正确的，但是当我在存储过程中调用它时，它没有显示任何内容：

declare   @itemgroupCode int
set       @itemgroupCode=118
declare   @todate datetime
set       @todate='15.april.15'

declare   @Group nvarchar(Max)
set       @Group=(SELECT [dbo].[CurrProduction] (118,'15.APRIL.2015'))
select @Group

SELECT *
FROM (
SELECT 
o.ItemCode as [Item],tm.ItemName as Dscription,o.Warehouse as Wr,obtn.LotNumber, 
itl1.quantity as qty ,tm.U_Reusb,@Group as Grp

from OINM o inner join OITL on OITL.DocType = o .TransType and OITL.DocNum = o.BASE_REF  and OITL.DocLine= o .DocLineNum and OITL .LocCode = o.Warehouse and o .ItemCode = OITL.ItemCode
inner join ITL1 on ITL1.LogEntry = OITL.LogEntry and ITL1.ItemCode=OITL.ItemCode
inner join OITM  tm on tm.ItemCode = ITL1.ItemCode 
inner join OITB on tm .ItmsGrpCod = OITB .ItmsGrpCod
INNER JOIN OWHS AS OH   ON o.Warehouse=OH.WhsCode
inner join OBTN on OBTN.SysNumber = ITL1.SysNumber and OBTN.ItemCode = ITL1.ItemCode and tm.ManBtchNum = 'Y'
 WHERE  --tm.ItmsGrpCod=108 and
  tm.ItemCode in (@Group) 
 and o.DocDate<=@todate ) as s  
PIVOT

 SUM(qty)
 FOR Wr IN (
 [DIS],[G&I],[GD-001],[GD-002],[GD-003],[GD-004],
 [GD-005],[GD-006],[GD-007],[GD-008],[GD-009],[GD-010],

当我粘贴IN CLAUSE时，该函数返回以下内容，它给出了正确的结果，但是当我传入函数调用的结果时，它没有显示任何内容

函数返回：

'FYCT-00063','FYCM-00016','FYCM-00064','FYCF-00018','FYCM-00021','FYOG-00016','FYCM-00004','FYCM-00031','FYCM-00042' function code is following.

**

ALTER FUNCTION [dbo].[CurrProduction]
(
@unit varchar(10), @date datetime
)
RETURNS Varchar(Max) 
AS
BEGIN
    -- Declare the return variable here
    DECLARE @ResultVar varchar(Max)
  SELECT DISTINCT @ResultVar='''' + REPLACE(STUFF((
   SELECT    ',',+CAST(OWOR.ItemCode AS VARCHAR(10)) [text()]
   FROM OWOR
   where OWOR.PostDate=@date AND OWOR.U_Unit=CASE
                                 when @unit=108 then 'Unit No1'
                                 when @unit=118 then 'Unit No 2'
                                 when @unit=119 then 'Unit No 3' END
    AND OWOR.Status!='C'
    FOR XML PATH('') , TYPE)
   .value('.','NVARCHAR(MAX)'),1,1,' '),',',''',''')+''''                    

    -- Return the result of the function
    RETURN @RESULTVAR
END

为了做你想做的事，该函数应该是Inline Table Valued函数。然后，您只需在IN中调用它即可。例如：

CREATE TABLE ttinline(id int)
GO

INSERT INTO dbo.ttinline
VALUES  (1),(2),(3)

CREATE FUNCTION fnInline()
RETURNS TABLE
AS
return SELECT * FROM dbo.ttinline
GO

SELECT * FROM dbo.ttinline WHERE id IN(SELECT * FROM dbo.fnInline())

输出：

id
1
2
3

修改

ALTER FUNCTION [dbo].[CurrProduction] ( @unit varchar(10), @date datetime ) RETURNS TABLE AS RETURN SELECT DISTINCT CAST(OWOR.ItemCode AS VARCHAR(10)) AS CODE FROM OWOR where OWOR.PostDate=@date AND OWOR.U_Unit=CASE when @unit=108 then 'Unit No1' when @unit=118 then 'Unit No 2' when @unit=119 then 'Unit No 3' END AND OWOR.Status!='C' GO DECLARE @itemgroupCode INT SET @itemgroupCode = 118 DECLARE @todate DATETIME SET @todate = '15.april.15' SELECT * FROM ( SELECT o.ItemCode AS [Item] , tm.ItemName AS Dscription , o.Warehouse AS Wr , obtn.LotNumber , itl1.quantity AS qty , tm.U_Reusb FROM OINM o INNER JOIN OITL ON OITL.DocType = o.TransType AND OITL.DocNum = o.BASE_REF AND OITL.DocLine = o.DocLineNum AND OITL.LocCode = o.Warehouse AND o.ItemCode = OITL.ItemCode INNER JOIN ITL1 ON ITL1.LogEntry = OITL.LogEntry AND ITL1.ItemCode = OITL.ItemCode INNER JOIN OITM tm ON tm.ItemCode = ITL1.ItemCode INNER JOIN OITB ON tm.ItmsGrpCod = OITB.ItmsGrpCod INNER JOIN OWHS AS OH ON o.Warehouse = OH.WhsCode INNER JOIN OBTN ON OBTN.SysNumber = ITL1.SysNumber AND OBTN.ItemCode = ITL1.ItemCode AND tm.ManBtchNum = 'Y' WHERE --tm.ItmsGrpCod=108 and tm.ItemCode IN ( SELECT CODE FROM [dbo].[CurrProduction](118, '15.APRIL.2015') ) AND o.DocDate <= @todate ) AS s PIVOT ( SUM(qty) FOR Wr IN ( [DIS], [G&I], [GD-001], [GD-002], [GD-003], [GD-004], [GD-005], [GD-006], [GD-007], [GD-008], [GD-009], [GD-010], [GD-011], [GD-012], [GD-013], [GD-014], [GD-015], [GD-016], [GD-017], [GD-018], [GD-019], [GD-020], [GD-021], [GD-022], [GD-023], [GD-024], [GD-025], [GD-026], [GD-027], [GD-028], [GD-029], [GD-030], [GD-031], [GD-032], [GD-033], [GD-034], [GD-035], [KHI AB], [KHI MM], [Loan], [LUB], [Main], [PCG - M1], [PCG - M2], [PHS], [PMG], [PRO], [REJ], [REP], [REP-V], [Selling], [SKP] ) )AS PVT
