Question

I have a dataset which contains phone data for a given period, i need to filter this data based on the hour of the day so i can use this in a chart which shows the peak periods.

So far, i have this expression:

=Count(IIF(DatePart("h", Fields!CallStart.Value = 7), Fields!ID.Value, 0))

So, what i had hoped this expression would do is replicate this SQL Query:

select * from PhoneData
where MONTH(callstart) = 7 and YEAR(callstart) = 2012 and DATEPART(HH, callstart) = 7
and Direction ='i' and Part1Device not like 'v%' and Continuation = '0'

The month and year are set in the dataset query.

Suffice to say, the expression doesn’t work and i can’t quite figure out why.. any help would be greatly appreciated.

Answer 1

Looks like your closing bracket for the DatePart function is in the wrong place. Try this.

=Sum(IIF(DatePart("h", Fields!CallStart.Value) = 7, 1, 0))
