Question

我在SQL Server Management Studio 2008上运行此SQL查询：

  SELECT  ItemId,
    DATEADD(HOUR,-4,CONVERT(DATETIME,LEFT([Date],8)+' '+
                    SUBSTRING([Date],10,2)+':'+
                    SUBSTRING([Date],12,2)+':'+
                    SUBSTRING([Date],14,2)+'.'+
                    SUBSTRING([Date],15,3))) [Date],
    [Object],
    SourceSite,
    DestSite
   FROM (  SELECT  ItemId,
            CONVERT(VARCHAR(18),[Date]) [Date],
            [Object],
            SourceSite,
            DestSite,
                        UserCode
    FROM JnlMediumMove) A
  WHERE UserCode = 'Automation'
  ORDER BY [Date] DESC;

此查询显示每个日期，但我只对当前日期前一天的日期感兴趣。因此，可以发送包含前一天活动的日常报告。

Answer 1

如果你添加到where子句：

and datediff(day, [date], getUTCDate()) = 1

需要注意的是UTC命令的时区是GMT。因此，根据您可能需要的事物范围增加时间来获得适当的时区。

因为您的专栏不是实际日期，请尝试执行以下操作：

    and dateDiff(day, CONVERT(DATETIME,
                    LEFT([Date],8)+' '+
                    SUBSTRING([Date],10,2)+':'+
                    SUBSTRING([Date],12,2)+':'+
                    SUBSTRING([Date],14,2)+'.'+
                    SUBSTRING([Date],15,3)
                    ), getUtcDate()) = 1

And isDate( CONVERT(DATETIME,
                    LEFT([Date],8)+' '+
                    SUBSTRING([Date],10,2)+':'+
                    SUBSTRING([Date],12,2)+':'+
                    SUBSTRING([Date],14,2)+'.'+
                    SUBSTRING([Date],15,3)
                    )
           ) = 1

整个查询将是：

SELECT  ItemId,
    DATEADD(HOUR,-4,CONVERT(DATETIME,LEFT([Date],8)+' '+
                    SUBSTRING([Date],10,2)+':'+
                    SUBSTRING([Date],12,2)+':'+
                    SUBSTRING([Date],14,2)+'.'+
                    SUBSTRING([Date],15,3))) [Date],
    [Object],
    SourceSite,
    DestSite
   FROM (  SELECT  ItemId,
            CONVERT(VARCHAR(18),[Date]) [Date],
            [Object],
            SourceSite,
            DestSite,
                        UserCode
    FROM JnlMediumMove) A
  WHERE UserCode = 'Automation'
  AND dateDiff(day, CONVERT(DATETIME,
                    LEFT([Date],8)+' '+
                    SUBSTRING([Date],10,2)+':'+
                    SUBSTRING([Date],12,2)+':'+
                    SUBSTRING([Date],14,2)+'.'+
                    SUBSTRING([Date],15,3)
                    ), getUtcDate()) = 1

And isDate( CONVERT(DATETIME,
                    LEFT([Date],8)+' '+
                    SUBSTRING([Date],10,2)+':'+
                    SUBSTRING([Date],12,2)+':'+
                    SUBSTRING([Date],14,2)+'.'+
                    SUBSTRING([Date],15,3)
                    )
           ) = 1

        ORDER BY [Date] DESC;

试试这个：

SELECT  ItemId,
DATEADD(HOUR,-4,CONVERT(DATETIME,LEFT([Date],8)+' '+
                SUBSTRING([Date],10,2)+':'+
                SUBSTRING([Date],12,2)+':'+
                SUBSTRING([Date],14,2)+'.'+
                SUBSTRING([Date],15,3))) [Date],
[Object],
SourceSite,
DestSite
FROM (  SELECT  ItemId,
        CONVERT(VARCHAR(18),[Date]) [Date],
        [Object],
        SourceSite,
        DestSite,
                    UserCode
  FROM JnlMediumMove 
  WHERE CAST(substring(convert(varchar(50), [Date]), 0, 5) + '-' +
  substring(convert(varchar(50), [Date]), 5, 2) + '-' +
  substring(convert(varchar(50), [Date]), 7, 2) AS DATETIME) = 
  CONVERT(date, DATEADD(day, -1, getdate()))) A --Converting to date again to remove the time part
WHERE UserCode = 'Automation'
ORDER BY [Date] DESC;
