FAQ
Hi all. I'm doing a drupal 5.1 Oracle db experimental port. I have a
first core installation more or less working.

Next target will be cck and views.

One problem was the need to remove the db_num_rows calls (unavailable in
Oracle). I've seen here and there an inappropriate use of this function
("select *" and db_num_rows in place of "select count(*)"), and I think
my patches can be useful also for performance under other databases.

I'll be glad to submit my patches. In case, tell me the best way to do
so, I'm new to the drupal project.

Best regards,
Gabriele Turchi

P.S.: I'm sorry, my english il alpha version...

    Cool! :)

    Note that we can't commit your patch to the Drupal 5 branch -- only
    bugfixes are committed to that branch. You'll want to provide
    patches for CVS HEAD so that the new functionality can become part of
    Drupal 6.

    You'll want to check with Larry Garfield -- he's working on PDO
    support for Drupal 6, and is also looking into removing db_num_rows
    (). See this week's thread about "PDO and database limitations" for
    more information.

    Hope that helps and looking forward to your contributions,

    @Gabrieli: Greetings! Hopefully what I'm working on will make Oracle support easier, too.

    @Dries: Since it looks like db_num_rows() is going to be an issue for more than just PDO, would you be open to separate patches that just do "SQL cleanup" to eliminate db_num_rows(), clean up tablename-in-prepared-statement problems, etc, either as lots of little patches (my preference, easier to test/debug) or a big cleanup patch? I believe that will be the largest remaining part of PDO anyway, but valuable to native-Oracle efforts etc. as well.

    I think that too.

    To be honest, the big part of my patches about db_num_rows are
    one-liner... (change the select using "count(*)" where only the record
    number is needed and turning upside-down a while loop when fetching
    data).

    Maybe, creating some sort of "semi-official" patches should be useful to
    do something like a "beta-test" during the "5." release.

    About changes, may I also add a "we don't really need a kilometer-long
    table and index names"? Oracle doesn't like that...
