Question

I want to provide 5 counts to SSRS from a conditional count on a column. For instance, suppose the column held the color of a product — green ,blue, red and yellow. What I would like to do is return the count of each in a single query.

Although I can accomplish getting this done using a case statement:

Select
      COUNT(*) 'Count',
      case
            When Color = 'BL' then 'Blue
            When Color = 'RD' then 'Red
            When Color = 'YL' then 'Yellow
            When Color = 'GR' then 'Green
            Else 'All Others'
      End as Payment
From COLORS(NoLock)
Group by
      case
            When Color = 'BL' then 'Blue
            When Color = 'RD' then 'Red
            When Color = 'YL' then 'Yellow
            When Color = 'GRthen ‘Green’
            Else 'All Others'
      End

When I use the dataset is SSRS, all I get is the a single count. I don’t want to create 4 dataset queries as I’m actually selection the records by the parameters start and end date and I would end up having 5 sets of date parameters.

Answer 1

This should do the trick

select count (*) as Total,
   sum (case when color='BL' then 1 else 0 end) as BlueTotal,
   sum (case when color='RD' then 1 else 0 end) as RedTotal,
   sum (case when color='YL' then 1 else 0 end) as YellowTotal,
   sum (case when color='GR' then 1 else 0 end) as GreenTotal
from Colors
