You Asked

HI Tom,

Can you please tell me what should be minimum row/processing count to use bulk collect/for-all .

My procedure would get around few 100s of records for record, should I go with bulk/for all or for loop.


Thanks

My rule of thumb is

1 row => no bulk
1-20rows => maybe
>20 rows => use bulk

because *typically* (not always) the moment you have more than 1 row, there is often no real upper limit on the number of rows you might encounter.

The "maybe" covers the difference between a fixed list of rows and a list that may grow over time.

Also...a lot depends on *where* you are running this from. If I have a 10second latency per insert, then I will be bulk binding the moment I get 2 rows :-)

But don't get too wrapped up in rules/numbers - go with what works best for your situation and your environment
