Question

I’m using PHP + Oracle and was wondering if there are any recommendations on where to commit my transactions. I call stored procedures to do all my inserts/updates/deletes, and currently am committing at the end of my stored procedures.

I was wondering:

1. Is there any difference between
   calling commit/rollback in my stored
   procedure vs calling oci_commit /
   oci_rollback in my PHP code based on
   the success of the stored procedure
   call.

2. Which is preferable? Originally
   I was thinking in the stored
   procedures themselves, but now I’m
   wondering, if there’s no difference,
   perhaps it would give me more
   flexibility to commit in the calling
   application code since I could call
   several stored procedures in a
   single transaction rather than
   having to write new stored
   procedures every time I want to
   mix/match a variety of SQL
   statements in a single transaction.

Thoughts?

Answer 1

I definitely agree with option 2, for the reasons you give. Having each stored procedure act as a separate transaction can be too limiting sometimes. Tom Kyte would back option 2 as well: see this AskTom thread for example.
