Hi all,
Just trying to sort this out.
I have a very simple calculation.
Step1
Round up the item price to the next dollar
Step 2
Add 10% to the result in step 1
Step 3
Round to the nearest point
Step 4
Use the result in step 3 to update the xxx db field
As I don't want to:
execute a SQL to retrieve the 100 recs.
Loop thru each rec and execute a singe update SQL for each rec
I want the DB to do all the work thru a single SQL command.
What's the best method for this calculation?
i.e. a stored calculation procedure ?
as we use this calculation in many places
where we could use a single SQL Update Command
that selects the 100 recs
and calls the stored calculation procedure
or perhaps a single SQL update command
that selects the 100 recs
that somehow contain this calculation embedded in the SQL
(not as a stored procedure)
Thanks,
Barry G. Sumpter
