## How to obtain Sum of count

 Author Message MVIT Old Hand Group: General Forum Members Points: 334 Visits: 85 The View obtains the first three columns , i need to add one more column(totalCount) to the view that obtains the totalCountCId CCId CCount totalCount1 a 3 61 a 3 61 b 3 61 c 3 62 b 2 62 b 2 62 a 2 62 a 2 63 v 1 6How to get the totalCount as 6 ?(Business rule for Cid=1 Ccount=3 Cid=2 Ccount=2 Cid=3 Ccount=1So the totalCount =3+2+1 =6) Steve Jones SSC Guru Group: Administrators Points: 327541 Visits: 20089 How are you getting the counts? are you basing this on the CCID column for a CID?It's better if you can give DDL like this:`CREATE TABLE mytable( CId int, CCId varchar(10), CCount int, totalCount int);GOINSERT MyTable VALUES (1, 'a',3, 6), (1, 'a', 3, 6), (1, 'b', 3, 6), (1, 'c', 3, 6), (2, 'b', 2, 6), (2, 'b', 2, 6), (2, 'a', 2, 6), (2, 'a', 2, 6), (3, 'v', 1, 6);go`Also, please explain the logic, don't just give some results and expect someone to interpret them to match your business rule.

Sean Lange SSC Guru Group: General Forum Members Points: 147501 Visits: 18565 Well the query that Chris posted returns the exact output you specified. If you need something different you have to explain it. We can't see your screen, we are not familiar with your project and we don't know the business rules. _______________________________________________________________Need help? Help us help you.

Are you sure you're not part Navaho? My mantra: No loops! No CURSORs! No RBAR! Hoo-uh!My thought question: Have you ever been told that your query runs too fast?My advice:INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.Need to UNPIVOT?

Some sample data would help too - exactly what will probably depend upon the view definition. “Write the query the simplest way.
