Question

我有以下SQL Server存储过程，当前端代码调用它时，它返回的返回值为0而不是总计数的选择。任何人都可以告诉我，我需要做些什么更改才能返回选择值而不是返回值

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER procedure [dbo].[getTotalSent1] 
(
   @vendorworksationID uniqueidentifier  ,
   @sdate date,
   @edate date
)
as 
begin
   select  
       camp.totalSent + bcamp.totalSent as totalSent 
   from 
       (select   
           COUNT(*) as totalSent  
        from 
           AdvertisedCampaignHistory a  
        where 
           CAST(a.CreationDate AS DATE) BETWEEN CAST(@sdate as DATE) AND CAST(@edate as DATE)   
           and a.CampaignID in (select cc.CampaignID 
                                from campaign cc, VendorWorkStation vw 
                                where cc.VendorWorkStationID = vw.VendorWorkStationID 
                                  and VendorID = @vendorworksationID))  as camp
   join 
       (select   
            COUNT(*) as totalSent  
        from  
            AdvertisedCampaignHistory a  
        where 
            CAST(a.CreationDate AS DATE) BETWEEN CAST(@sdate as DATE) AND CAST(@edate as DATE)
            and a.CampaignID in (select bc.BCampaignID 
                                 from BeaconCampaign bc, VendorWorkStation vw 
                                 where bc.VendorWorkStationID = vw.VendorWorkStationID 
                                   and VendorID = @vendorworksationID)) as bcamp on 1=1
  end

输出：

Totalsent
---------
240

return 
-----
0

它返回0，我想要总发送值

Answer 1

CREATE PROCEDURE getTotalSent1
AS
DECLARE @TotalSent int

-- Do some work here

SELECT @TotalSent = 240 
RETURN @TotalSent
GO

-- EXEC CODE
DECLARE @totalsent int
EXEC @totalsent = dbo.getTotalSent1
SELECT @totalsent as totalSent

Answer 2

  ALTER procedure [dbo].[getTotalSent1] 
    (
       @vendorworksationID uniqueidentifier  ,
       @sdate date,
       @edate date

       @total_set int output
    )
    as 
    `enter code here`

   return

像这样得到param

   declare @got_it int
    exec [dbo].[getTotalSent1] xxx,yyy,@total_set=@got_it output

`

Answer 3

试试这个：

SET ANSI_NULLS ON
    GO
    SET QUOTED_IDENTIFIER ON
    GO

    ALTER procedure [dbo].[getTotalSent1] 
    (
       @vendorworksationID uniqueidentifier  ,
       @sdate date,
       @edate date
    )
    as 
    begin
    DECLARE @totalSent INT
       select  
           @totalSent =camp.totalSent + bcamp.totalSent 
       from 
           (select   
               COUNT(*) as totalSent  
            from 
               AdvertisedCampaignHistory a  
            where 
               CAST(a.CreationDate AS DATE) BETWEEN CAST(@sdate as DATE) AND CAST(@edate as DATE)   
               and a.CampaignID in (select cc.CampaignID 
                                    from campaign cc, VendorWorkStation vw 
                                    where cc.VendorWorkStationID = vw.VendorWorkStationID 
                                      and VendorID = @vendorworksationID))  as camp
       join 
           (select   
                COUNT(*) as totalSent  
            from  
                AdvertisedCampaignHistory a  
            where 
                CAST(a.CreationDate AS DATE) BETWEEN CAST(@sdate as DATE) AND CAST(@edate as DATE)
                and a.CampaignID in (select bc.BCampaignID 
                                     from BeaconCampaign bc, VendorWorkStation vw 
                                     where bc.VendorWorkStationID = vw.VendorWorkStationID 
                                       and VendorID = @vendorworksationID)) as bcamp on 1=1

    return @totalSent 
      end

Answer 4

BEGIN后SET NOCOUNT ON;

这将禁用存储过程的默认返回值，以便您获得查询结果。

作为旁注，您需要用ANSI等效替换您的专有联接......

e.g。 ......

FROM tblA a
JOIN tblB b
ON   a.key = b.key

最好避免在WHERE子句中进行连接。
