Eager-2-Learn Updating a Map inside a For Loop?
Hi,
I wanted to know if it is bad practice to update a map inside a for loop. When I say update I do not mean a DML update--as I know better! :) I mean can I do a get on a map and a put on that same map inside a loop. I want to read thorugh records in my loop and if I find a matching key in my map over and over, I want to keep updating the map with the latest records data? Once out of the loop then I figure I should be able to do my DML on the map.
