Hi,

I have this query

select count(*) as Total, ST.ApplicationType,
cast(((count(*) * 100.0) / 741) as DECIMAL(10,2)) as Percentage from AppRepository AP
left join SourceType ST on AP.applicationType = ST.SourceID
where AP.Retired = 0
group by AP.ApplicationType, ST.ApplicationType

Open in new window


that generate this output

Total    ApplicationType                                        Percentage 
5	Access	                                                      0.67
21	Client	                                                      2.83
1	Crystal Reports	                                     0.13
303	Distributed	                                    40.89
25	Distributed/Mainframe	                   3.37
1	Function	                                                      0.13
242	Mainframe	                                     32.66
1	Other	                                                      0.13

the problem that I am having is the percentage in my query I hard coded "741"
that supose to be the total of my cound and I don't know how to get it.

In my query I have the percentage:

cast(((count(*) * 100.0) / 741) as DECIMAL(10,2)) as Percentage

cast(((count(*) * 100.0) / ?????????) as DECIMAL(10,2)) as Percentage


741 is the sum of my count how can I do this

sum(count(*)) ?????

See edited code ... Note the only change if the query that replaces your hard coded number
select count(*) as Total, ST.ApplicationType,
cast(((count(*) * 100.0) / (select count(*) from AppRepository where AP.Retired = 0 ) as DECIMAL(10,2)) as Percentage 
from AppRepository AP
left join SourceType ST on AP.applicationType = ST.SourceID
where AP.Retired = 0
group by AP.ApplicationType, ST.ApplicationType
