This is not a SDE question. File GDB.
I have a general question on looping through feature classes in a file geodatabase. I have (attached) a python script that adds a ton of fields and calculates them. It seems to run okay for 2-3 feature classes but by the time it hits the 4th or 5th one it often breaks down to Error 99999 or a dreaded schema lock error. Then if I comment out the first 2-3 fc's and run it just for 4 and 5 one at a time it runs fine.
Is there some way to 'clear' the loop at the end or should I MakeTableView do everything, export the table, then Delete the TableView? Should I be using environments too instead of using the long paths?
I don't have many people look at my code and have no real training so if there are any very very obvious things I'm doing wrong please let me know.
