Sql 基于日期筛选表行

我有以下数据集：

这指定了每个设施的任务周期，“cycleperiod”列指定了周期的开始和结束日期

任务由单独的列指定，指定startdate和completeion状态，如so date~status

状态为“0”表示未完成，“1”表示已完成

现在，我想筛选行，以便为我获得的每个设施：

当前周期

上一个周期至少有一个任务未完成

如果下一个周期在当前日期的3天内开始，则为下一个周期

到目前为止，我这样做是为了得到每个设施的当前周期，但无法找出每个设施的逻辑

   select *  from ##finalTempTable1 
   where Cast(LTRIM(RTRIM(SUBSTRING(CyclePeriod, 0, 11))) as date) >=   cast(getdate() as date)
   and cast(LTRIM(RTRIM(SUBSTRING(CyclePeriod, CHARINDEX(''o'',CyclePeriod,0) + 2, 11))) as date) <= cast(getdate() as date);

我们将非常感谢您在这方面提供的任何帮助。

我不能100%确定您想做什么，但如果我正确理解您的意思，这里有一个开始：

select 
    cycleperiod
from 
    ##finalTempTable1 
where 
    Cast(LTRIM(RTRIM(SUBSTRING(CyclePeriod, 0, 11))) as date) >=   cast(getdate() as date)
    and cast(LTRIM(RTRIM(SUBSTRING(CyclePeriod, CHARINDEX(''o'',CyclePeriod,0) + 2, 11))) as date) <= cast(getdate() as date)
    and right(cycleperiod) = '0'
UNION

select 
    max(b.cycleperiod)
from 
    ##finalTempTable1 as a 
    inner join (
        select 
            b.CyclePeriod
        from
            ##finalTempTable1 as b
        WHERE 
            and right(cycleperiod) = '0'
    )as b
        ON Cast(LTRIM(RTRIM(SUBSTRING(b.CyclePeriod, 0, 11))) as date) < Cast(LTRIM(RTRIM(SUBSTRING(b.CyclePeriod, 0, 11))) as date) 
where 
    Cast(LTRIM(RTRIM(SUBSTRING(CyclePeriod, 0, 11))) as date) >=   cast(getdate() as date)
    and cast(LTRIM(RTRIM(SUBSTRING(CyclePeriod, CHARINDEX(''o'',CyclePeriod,0) + 2, 11))) as date) <= cast(getdate() as date)

UNION

select 
    min(b.cycleperiod)  
from 
    ##finalTempTable1 as a 
    inner join (
        select 
            b.CyclePeriod
        from
            ##finalTempTable1 as b
        WHERE 
            and right(cycleperiod) = '0'
    )as b
        ON Cast(LTRIM(RTRIM(SUBSTRING(b.CyclePeriod, 0, 11))) as date) > Cast(LTRIM(RTRIM(SUBSTRING(b.CyclePeriod, 0, 11))) as date) 
where 
    Cast(LTRIM(RTRIM(SUBSTRING(CyclePeriod, 0, 11))) as date) >=   cast(getdate() as date)
    and cast(LTRIM(RTRIM(SUBSTRING(CyclePeriod, CHARINDEX(''o'',CyclePeriod,0) + 2, 11))) as date) <= cast(getdate() as date)
    and Cast(LTRIM(RTRIM(SUBSTRING(b.CyclePeriod, 0, 11))) as date) <= <= dateadd(d,3,getdate() )

基本上，将所需的三组数据合并在一起

要获取下一个和上一个CyclePeriod，请将表连接到自身

为了只得到一个结果，beofre和after可以使用max和min，因为看起来没有重叠的句点，并且日期的格式可以按字母顺序排序

如果您想要的不仅仅是循环周期列，那么可以使用另一个临时表或类似的方式将此结果再次连接到表中：

select 
    d.*
from 
    ##finalTempTable1  as d
    inner join(
    select 
        cycleperiod
    from 
        ##finalTempTable1 
    where 
        Cast(LTRIM(RTRIM(SUBSTRING(CyclePeriod, 0, 11))) as date) >=   cast(getdate() as date)
        and cast(LTRIM(RTRIM(SUBSTRING(CyclePeriod, CHARINDEX(''o'',CyclePeriod,0) + 2, 11))) as date) <= cast(getdate() as date)
        and right(cycleperiod) = '0'
    UNION

    select 
        max(b.cycleperiod)
    from 
        ##finalTempTable1 as a 
        inner join (
            select 
                b.CyclePeriod
            from
                ##finalTempTable1 as b
            WHERE 
                and right(cycleperiod) = '0'
        )as b
            ON Cast(LTRIM(RTRIM(SUBSTRING(b.CyclePeriod, 0, 11))) as date) < Cast(LTRIM(RTRIM(SUBSTRING(b.CyclePeriod, 0, 11))) as date) 
    where 
        Cast(LTRIM(RTRIM(SUBSTRING(CyclePeriod, 0, 11))) as date) >=   cast(getdate() as date)
        and cast(LTRIM(RTRIM(SUBSTRING(CyclePeriod, CHARINDEX(''o'',CyclePeriod,0) + 2, 11))) as date) <= cast(getdate() as date)

    UNION

    select 
        min(b.cycleperiod)  
    from 
        ##finalTempTable1 as a 
        inner join (
            select 
                b.CyclePeriod
            from
                ##finalTempTable1 as b
            WHERE 
                and right(cycleperiod) = '0'
        )as b
            ON Cast(LTRIM(RTRIM(SUBSTRING(b.CyclePeriod, 0, 11))) as date) > Cast(LTRIM(RTRIM(SUBSTRING(b.CyclePeriod, 0, 11))) as date) 
    where 
        Cast(LTRIM(RTRIM(SUBSTRING(CyclePeriod, 0, 11))) as date) >=   cast(getdate() as date)
        and cast(LTRIM(RTRIM(SUBSTRING(CyclePeriod, CHARINDEX(''o'',CyclePeriod,0) + 2, 11))) as date) <= cast(getdate() as date)
        and Cast(LTRIM(RTRIM(SUBSTRING(b.CyclePeriod, 0, 11))) as date) <= <= dateadd(d,3,getdate() )
    ) as c
        on d.cycleperiod = c.CyclePeriod
