Question

我有以下数据集：

这指定了每个设施的任务周期，“周期”和“周期”。列指定循环的开始和结束日期，

并且使用指定startdate和completeion状态的各个列指定任务，如此（date~status），

＆＃39; 0＆＃39;在状态意味着不完整和＆＃39; 1＆＃39;意味着完整。

现在我想过滤行，以便我得到的每个设施：

当前周期
前一个周期，至少有一个任务不完整
如果下一个周期以3天的当前日期开始，则为下一个周期

到目前为止，我已经做到这一点，以获得每个设施的当前周期，但无法找出

   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);

在这方面的任何帮助将受到高度赞赏。

我不是百分之百确定你想要做什么但是如果我理解你的话，这里是首发：

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() )

基本上联合你想要的三组数据。

获取下一个和上一个循环周期将表连接到自身

只获得一个结果，并且在您可以使用max和min之后，因为它看起来没有重叠的句点，并且您的日期格式化为按字母排序有效。

如果你想要的不仅仅是循环周期列，那么再次将这个结果连接到表中，或者使用另一个临时表，或者像这样：

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

根据日期过滤表格行
