Question

我已经集成了与MSSQL的系统连接。系统根据寄售编号获取所有记录。编号是整数形式，如（12到15）数字。查询工作正常，但获取重复结果＆＃34;处理源HUB＆＃34;在与事务时间相关的行中（DATETIME列名）。下面是我的查询和截图。

SELECT ct.transactionTime,
       st.TrackingStatus Event,
       ct.consignmentNumber,
       ct.currentLocation AS LOCATION,
       CONVERT(NVARCHAR, c.bookingDate, 105) BookingDate,
       CASE
            WHEN ct.stateID = '18' THEN 'Consignment Arrived At ' + ct.currentLocation
                 + ' Main Office' +
                 ' on ' + CONVERT(NVARCHAR, transactionTime, 105)
            WHEN ct.stateID = '1' THEN ' Conginment has been Booked on ' +
                 CONVERT(NVARCHAR, c.bookingdate, 105)
                 + ' in ' + ct.currentLocation
            WHEN ct.stateID = '2' OR ct.stateID = '3' OR ct.stateID = '4' THEN
                 'Processing at Origin HUB'

    ORDER BY ct.transactionTime desc

请帮帮我。

记录不重复，Datetime列具有不同的值，将该列数据转换为仅日期为强制转换：CAST(column as Date)然后如果需要，则仅在select语句中应用不同的。

要根据您的评论获得状态明智的单个记录，请使用PARTITION BY，如下所示：

;WITH T AS
(
    SELECT [DateTime],
    [Status],
    Location,
    ROW_NUMBER() OVER (PARTITION BY [Status],Location ORDER BY Location) AS PartNo
    From TableName
)

SELECT
    *
FROM T WHERE PartNo=1

MSSQL查询结果中重复记录
