We have a batch process that does a long series of updates, inserts, and deletes. Right now we are using a script to execute sql.

When is it appropriate to move this to PL/SQL and use array processing? couple of things I thought of...

1. We have one large table that has a column with 5-6 distinct values. We are often doing

select stuff
from big_table
where column = 'BLAH'

Would it be a good idea to bulk collect the rowids or even just select the entire row into a pl/sql table? and essentially break the table up into 5 smaller tables?

then do a forall statement to do my update?

In general when should you move from update, insert,delete statements with sub-queries to array processing? anyone have any rules of thumb?
