Hey everyone...

Im having some issues with a filter I need to add to one of my querys. I need to filter a table by date, basically what I need is to filter the results depending on the hour that the query is executed, for example if I run the query after 6pm, it should only display values from 6am to 6pm of today... but if I run the report anytime between 6am and 6pm of today, it should display values from 6pm of yesterday to 6am of today...

Please help :P :D

   @dtEnd datetime =
      when cast(GetDate() as TIME) < '6:00' then DateAdd(Hour, -6, dateadd(Day, DateDiff(Day, 0, GetDate()), 0))   -- 6pm yesterday
      when cast(GetDate() as TIME) < '18:00' then DateAdd(Hour, 6, dateadd(Day, DateDiff(Day, 0, GetDate()), 0))   -- 6am today
      else DateAdd(Hour, 18, dateadd(Day, DateDiff(Day, 0, GetDate()), 0))   -- 6pm today

   @dtStart datetime = dateadd(Hour, -12, @dtEnd) 

   MyDatetime between @dtStart and @dtEnd
