Parimala writes "I have a meter table which has cols from P1 to P50 with MtrdID and Date being composite key. On inserting new rows and also upadting rows onto his table I have to sum up individual cols P1 through P50 and also aggregate all the 50 cols based on date.i.e
Aggregate= sum(p1)+....sum(p50) and update another table dealticket which has Total and P1 through P50 as columns.
In other words dealticket.P1 = Sum(P1) in metertable on a particluar date and so on till P50. Dealticket.Aggregate= Sum(p1) +...Sum(p50) from metertable based on particular date.
I want to know the optimal way of doing this in the update and Insert trigger.
thanks" |
