【问题描述】：

我有一个表并触发正在执行一些计算和更新列的表。

我想更新输入模式字段，希望在表格中明智地设置 0 和 1 天。我编写了以下代码，但无法正常工作。

WITH CTE AS
(
    SELECT 
        ROW_NUMBER() OVER (ORDER BY Convert(datetime, el.M_Edatetime)) AS ROW,
        el.LogId 
    FROM 
        Essl_logdata el 
    INNER JOIN
        Inserted i ON el.EnrollNo = i.EnrollNo 
                   AND el.M_Edatetime = i.M_Edatetime
    WHERE 
        el.EnrollNo = @INS 
        AND Convert(Date, el.M_Edatetime) = Convert(date, @M_datetime)
)
UPDATE Essl_logdata 
SET InOutMode = '0' 
FROM CTE 
WHERE ROW%2 <> 0 AND Essl_logdata.LogId = CTE.LogId;

WITH CTE AS
(
    SELECT 
        ROW_NUMBER() OVER (ORDER BY COnvert(datetime, el.M_Edatetime)) AS ROW,
        el.LogId 
    FROM 
        Essl_logdata el 
    INNER JOIN
        Inserted i ON el.EnrollNo = i.EnrollNo 
                   AND el.M_Edatetime = i.M_Edatetime 
    WHERE
        el.EnrollNo = @INS 
        AND Convert(Date, el.M_Edatetime) = Convert(date, @M_datetime)
)
UPDATE Essl_logdata 
SET InOutMode = '1' 
FROM CTE 
WHERE ROW%2 = 0 AND Essl_logdata.LogId = CTE.LogId;

预期结果如下。

触发器中的当前查询显示结果如下。

【问题讨论】：

我看不出这两张图片有何不同。当问题似乎集中在“InOutMode”列上时，为什么突出显示“月份”列也不清楚。一些样本数据和预期结果，作为文本，会显着改善这个问题。
抱歉 Inoutmode 列很重要，我想更新该列

【解决方案1】：

WITH CTE AS
        (
            SELECT ROW_NUMBER() OVER(PARTITION BY COnvert(date,M_Edatetime),EnrollNo ORDER BY COnvert(datetime,M_Edatetime))AS ROW,Logid,M_Edatetime,EnrollNo FROM Essl_logdata  group by M_Edatetime,Logid,EnrollNo
        )           
        Update Essl_logdata set InOutMode = '1' FROM CTE WHERE ROW%2 = 0 and Essl_logdata.LogId = CTE.LogId;

WITH CTE AS
        (
            SELECT ROW_NUMBER() OVER(PARTITION BY COnvert(date,M_Edatetime),EnrollNo ORDER BY COnvert(datetime,M_Edatetime))AS ROW,Logid,M_Edatetime,EnrollNo FROM Essl_logdata  group by M_Edatetime,Logid,EnrollNo
        )       
        Update Essl_logdata set InOutMode = '0' FROM CTE WHERE ROW%2 <> 0 and Essl_logdata.LogId = CTE.LogId;

我找到了这个解决方法
