这是我到目前为止写的代码

SELECT        SR_AREA, INS_PRODUCT, RESOLUTION_CD, CREATED AS DATEADD, COUNT(*) AS DAY
FROM            S_SRV_REQ WITH (NOLOCK)         
WHERE        (dbo.fn_dstoffset(CREATED) >= '3-1-2016') AND (dbo.fn_dstoffset(CREATED) <= DATEADD(D, 1, '3-31-2016')) AND (INS_PRODUCT='RM')
GROUP BY INS_PRODUCT, RESOLUTION_CD, SR_AREA, CREATED
ORDER BY SR_AREA,INS_PRODUCT,RESOLUTION_CD DESC

如果您想按日期分组，只需使用Created上的DATE（）函数即可和DATE（Created）这样分组

SELECT        SR_AREA, INS_PRODUCT, RESOLUTION_CD, DATE(CREATED) AS DATEADD, COUNT(*) AS DAY
FROM            S_SRV_REQ WITH (NOLOCK)         
WHERE        (dbo.fn_dstoffset(CREATED) >= '3-1-2016') AND (dbo.fn_dstoffset(CREATED) <= DATEADD(D, 1, '3-31-2016')) AND (INS_PRODUCT='RM')
GROUP BY INS_PRODUCT, RESOLUTION_CD, SR_AREA, DATE(CREATED)
ORDER BY SR_AREA,INS_PRODUCT,RESOLUTION_CD DESC

这将返回（将,DATEADD ASC添加到订单末尾）

Electronic Payment  RM  Transfer to CCV2    March, 01 2016 00:00:00     5
Electronic Payment  RM  Transfer to CCV2    March, 02 2016 00:00:00     2
Electronic Payment  RM  Transfer to CCV2    March, 03 2016 00:00:00     4

很奇怪，DATE（）不适合你...也许尝试DATE_FORMAT

SELECT        SR_AREA, INS_PRODUCT, RESOLUTION_CD, DATE_FORMAT(CREATED,'%Y-%m-%d') AS DATEADD, COUNT(*) AS DAY
    FROM            S_SRV_REQ WITH (NOLOCK)         
    WHERE        (dbo.fn_dstoffset(CREATED) >= '3-1-2016') AND (dbo.fn_dstoffset(CREATED) <= DATEADD(D, 1, '3-31-2016')) AND (INS_PRODUCT='RM')
    GROUP BY INS_PRODUCT, RESOLUTION_CD, SR_AREA, DATE_FORMAT(CREATED,'%Y-%m-%d')
    ORDER BY SR_AREA,INS_PRODUCT,RESOLUTION_CD DESC, DATEADD ASC

更新 OP提到SQL Server而不是MySQL。所以请改用

SELECT        SR_AREA, INS_PRODUCT, RESOLUTION_CD, CONVERT(VARCHAR(19),CREATED,111) AS DATEADD, COUNT(*) AS DAY
        FROM            S_SRV_REQ WITH (NOLOCK)         
        WHERE        (dbo.fn_dstoffset(CREATED) >= '3-1-2016') AND (dbo.fn_dstoffset(CREATED) <= DATEADD(D, 1, '3-31-2016')) AND (INS_PRODUCT='RM')
        GROUP BY INS_PRODUCT, RESOLUTION_CD, SR_AREA, CONVERT(VARCHAR(19),CREATED,111)
        ORDER BY SR_AREA,INS_PRODUCT,RESOLUTION_CD DESC, DATEADD ASC
