Question

我有用户使用修复28 CheckList项目，每天用户必须输入每个清单项目的价值。

用户有时会部分填写列表或保持不完整，所以我需要告诉他们你已经离开了清单INCOMPLETE或填充了PARTIALLY因此保持一个名为“trans_status”的字段，默认情况下在数据库中用0表示不完整和一次用户填写数据值为1，其中28个条目混合1和0表示PARTIAL，如果所有28个enties都表示INCOMPLETE，如果所有1表示已完成。

这是结构

CREATE TABLE [dbo].[VTRCheckListDetails](
    [userid] [int] NULL,
    [branchid] [int] NULL,
    [vtrRespDate] [date] NULL,
    [CLid] [int] NULL,
    [VtrValue] [varchar](5) NULL,
    [trans_status] [int] NULL,
    [last_updated] [int] NULL
 ) ON [PRIMARY]

以下是样本数据

我想要的是当我运行查询时它应该在日期上分组并根据trans_status显示这样的数据

Date.............Status
30-12-12..........Partial (can be complete, incomplete)

Answer 1

SELECT   userid     ,
         vtrRespDate,
         CASE
                  WHEN MAX(trans_status) = 0
                  THEN 'InComplete'
                  WHEN MIN(trans_status)=1
                  THEN 'Complete'
                  ELSE 'Partial'
         END AS status
FROM     VTRCheckListDetails
GROUP BY userid,
         vtrRespDate

Answer 2

SELECT  vtrRespDate,
        CASE COUNT(CASE trans_status WHEN 1 THEN 1 END)
        WHEN 0 THEN
                'Incomplete'
        WHEN COUNT(*) THEN
                'Complete'
        ELSE
                'Partial'
        END AS Status
FROM    VTRCheckListDetails
GROUP BY
        vtrRespDate
