Remove time from date in Cognos Report Studio

Question

I am working with Cognos Reporting Studio. What I'm trying to do is to dispaly a count of items that fall in a range of dates. I am to display the counts for the year selected and the two previous years. But there is a fourth count being displayed with a blank year. Now I have come to think that this is becasue of then time attached to the date. So when the max date value is Mar 1, 2013 12:00:00AM, then Mar 1, 2013 06:17:00AM falls outside of that range. I need to remove the time from the dates. Here is what I'm currently using:

Case

when [GCR_RECEIVED_DT] between cast(substring ([FromDate],1,10),date) 
and _add_years(cast(substring ([ToDate],1,10),date),-2) 
then extract(year, _add_years([ToDate],-2) )

when [GCR_RECEIVED_DT] between _add_years(cast(substring ([FromDate],1,10),date),1)
and _add_years(cast(substring ([ToDate],1,10),date),-1) 
then extract(year,_add_years([ToDate],-1))

when [GCR_RECEIVED_DT] between _add_years(cast(substring ([FromDate],1,10),date),2)
and cast(substring ([ToDate],1,10),date) 
then extract(year,[ToDate])

end

I was told that I should use cast and substring. But I keep getting this error:

An error occurred while performing operation 'sqlPrepareWithOptions' status='-9'.

Along with this big message. I'm sure I don't have to include all of this, but I'm going to.

I've also tried to_date instead of cast. But I still get the same thing. Any help?

Answer 1

I just used _add_days with my ToDate so the max date is now Mar 2, 2013 12:00:00AM. This alows cognos to count the Mar 1, 2013 dates properly.
