Hi,
I'm trying to add another top 6 case statement to calulate the day before stats for a category field. Can this be included in the case statement?
Select Top 6 c.INTI_CATEGORY, count(c.ID) As TotalCat, --actual results
Case When c.OCCURED_DT = DATEADD("d",-1,GETDATE()) --calulate yesterday results
Then count(c.ID)End AS TotalCatYesterday
From DIM_CALL c
Where TYPE = 'Incident'
And c.OPEN_FLAG = 1 and c.ETL_CURRENT =1
Group by
c.INTI_CATEGORY ,
c.OCCURED_DT
Order By TotalCat Desc

do you mean getting previous ranks for top 6 items today or do you mean getting top 6 items for today and yesterday side by side?

Top 6 rank today and yesterday side by side, is this possible in same query?...been trying to just pull the records for yesterday using the occured date field below to exclude calls less than datetime but I'm struggling a bit to get them side by side
Select Top 6 c.INTI_CATEGORY, count(c.ID) As TotalCat
From DIM_CALL c
Where TYPE = 'Incident'
And c.OPEN_FLAG = 1 and c.ETL_CURRENT =1
And c.OCCURED_DT <= '2013-01-08 23:59:59' /*And c.OCCURED_DT <= '2013-01-08 23:59:59'*/--been trying to just get figure here
--DATEADD(d,-1,GetDate())
Group by c.INTI_CATEGORY
Order By TotalCat Desc

I'm getting c.OCCURED_DT cant be bound on the first 2 below
MAX(CASE WHEN DATEDIFF(dd,0,c.OCCURED_DT)= DATEDIFF(dd,0,GETDATE()) THEN INTI_CATEGORY END) AS TodayCat,
MAX(CASE WHEN DATEDIFF(dd,0,c.OCCURED_DT)= DATEDIFF(dd,1,GETDATE()) THEN INTI_CATEGORY END) AS YestCat
Also, I see you have entered actual dates, is it possible for the query to recalculate on a daily basis?
Thanks

Its not returning what I would expect to see...this the what I have already, what I would like to see is the same for TotalCatYest, so CategoryYest and TotalCatYest in next 2 columns.
Category TotalCatToday
Central 129
Local 93
Core Applications 74
Printers 54
Mail Services 23
Thin Client 21
Your result shows this, also strangely you have one different from my one where Domain Services is Printers.
1 NULL Central
2 NULL Local
3 NULL Core Applications
4 NULL Domain Services
5 NULL Mail Services
6 NULL Thin Client

OPEN_FLAG = 1? means all calls that are open
and c.ETL_CURRENT=1? means using current up to date dataset information, if not it will return all records and we only want the current ones that are open.
Basically is just means show me everything that is open and valid.

This returns the top 6 current records, so 2 columns one with the cat name and the other with the cat total. So really just need to include the previous days records side by side or even on its own query for now.
--return top 6 only
Select Top 6 c.INTI_CATEGORY, count(c.ID) As TotalCat
From DIM_CALL c
Where TYPE = 'Incident'
And c.OPEN_FLAG = 1 and c.ETL_CURRENT =1
Group by c.INTI_CATEGORY
Order By TotalCat Desc

how can you guarantee that same categories will come in top 6 in previous day too?

The top 6 count of ID and grouping of the category returns the top highest records, if all the records that are today are left out by only looking at occured date yesterday and backwards from there I would have thought that would have calculated the top 6 previous records only correctly? leaving out the current days selection. Otherwsie the only other way I can think of is to aggregate all the new current records and subtract these from all other open records from the previous days figure.
The categories may have changed slightly from previous day too, so the may differ slightly if a change has happened.
Does that help?
Also, I can check yesterdays results as I have a record, so can I change this query to just look at yesterday results leaving out todays by using the OCCURRED_DT field, if I have to have 2 queries one for today and one for yesterday I can work with that.
--return top 6 only
Select Top 6 c.INTI_CATEGORY, count(c.ID) As TotalCat
From DIM_CALL c
Where c.OCCURED_DT < DateAdd(dd,0,GETDATE())-1
and TYPE = 'Incident'
And c.OPEN_FLAG = 1 and c.ETL_CURRENT =1
Group by c.INTI_CATEGORY
Order By TotalCat Desc
Also, here I've asked for yesterdays date but the date is not doing anything, I need to bind it to the category count?
Declare @Date1 DateTime
Set @Date1 = '2013-01-08'
--return top 6 only
Select Top 6 c.INTI_CATEGORY, count(c.ID) As TotalCat,@Date1
From DIM_CALL c
--Where c.OCCURED_DT <= '2013-01-08' -- < DateAdd(dd,0,GETDATE())-1
where TYPE = 'Incident'
And c.OPEN_FLAG = 1 and c.ETL_CURRENT =1
Group by c.INTI_CATEGORY
Order By TotalCat Desc
