可以在sql存储过程本身中应用相同的逻辑来获得与以下链接帖子中所做的相同的结果，而不是使用LINQ吗？
这是我的存储过程
CREATE PROC [dbo].[WF_SPScanningReport_S]
(
@COMPANYID VARCHAR(20),
@FROMDATE DATETIME,
@TODATE DATETIME,
@FromRecord int,
@ToRecord int,
@SortString varchar(200)
)
AS
BEGIN
declare @Query nvarchar(Max)
if(ISNULL(LTRIM(RTRIM(@SortString)),'') <> '')
set @SortString='order by '+@SortString
else
set @SortString='order by IMAGEID'
SET NOCOUNT ON
set @Query=' CREATE TABLE #TABLE
(IMAGEID INT ,
SCANDATE DATETIME,
COUNT INT
)
INSERT INTO #TABLE(IMAGEID , SCANDATE)
SELECT IMAGEID , CAST(CONVERT(VARCHAR(10), SCAN_DATE,101) AS DATETIME) SCANDATE FROM WF_IMAGES
WHERE COMPANYID='''+@COMPANYID+''' AND SCAN_DATE BETWEEN '''+cast(@FromDate as varchar)+''' AND '''+cast(@ToDate as varchar)+''' AND IMAGE_NAME <> ''BLANK.PDF'' AND ISNULL(''Reviewed'','''') <> ''X''
UPDATE #TABLE
SET COUNT = S.COUNT1
FROM #TABLE T, (SELECT COUNT(SCANDATE) AS COUNT1 ,SCANDATE FROM #TABLE GROUP BY SCANDATE) S
WHERE T.SCANDATE= S.SCANDATE
SELECT * FROM (SELECT Distinct row_number() over ('+@SortString+') as RowNum,
IMAGEID, SCANDATE, COUNT FROM #TABLE )AS RowConstrainedResult
Where RowNum >'+cast(@FromRecord as varchar)+' AND RowNum <= '+cast (@ToRecord as varchar)+'
DROP TABLE #TABLE '
exec (@Query)
PRINT @Query
SET NOCOUNT OFF
END
这是我的SP结果

第一列有关于哪个Group By完成的scandate，第二列有单个单元格中具有相同扫描日期的图像ID - 逗号分隔，最后计算单个单元格中图像ID计数的colimn
答案 0 :(得分：0)
querstion comma delimited list as a single string, T-SQL提供了如何获取按特定字段分组的逗号分隔列表的说明。
以下代码段显示了如何获取结果数据集并将其透视，如上所述。
select distinct t1.scantime,
STUFF(
(SELECT ',' + convert(varchar(10), t2.ImageId, 120)
FROM yourtable t2
where t1.scantime = t2.scantime
FOR XML PATH (''))
, 1, 1, '') AS imageids
from yourtable t1
但是，您需要重构现有的存储过程，以便不进行不必要的中间查询以获得此结果。
