Auto commit Off how will it effect us ?

[Sai Hertz And Control Systems]

Dear all ,

Permit me to gain some of your most valuable knowledge ...........

Our intrAnet server has the following spec
1. RH 9.0
2. Postgresql 7.3.4
3. PHP 4.3.3
4. GCC 3.2.2

Till date my front end language (PHP) use to simply pass the data to
postgresql in case of insert and
update we were not using
1 BEGIN COMMIT block in PHP till date thanks to auto-commit-ON in postgreql
2. ROLLBACK script in PHP script


And now when our company has decided to switch over to postgresql 7.4
we have some doubt
1. Do we have to include BEGIN and COMMIT block around the insert
process . (Because Postgresql 7.4 has auto-commit-OFF) in our PHP scripts
2. Not only this do we also have to port the pgSQL functions which use
to do inserts into a third table such that
data gets committed on function execution


Please provide us any kinda information so that we can happily switch to
postgressql 7.4



Regards,
V Kashyap

I think you have misunderstood... autocommit works as it always has in
7.4, the difference is that the logic to turn it off is now left to the
client side instead of trying to manage it within the server.

ie.

phppgadmin=# select version();
version
-------------------------------------------------------------
PostgreSQL 7.4 on i586-pc-linux-gnu, compiled by GCC 2.95.3
(1 row)

phppgadmin=# set autocommit = off;
ERROR: SET AUTOCOMMIT TO OFF is no longer supported
phppgadmin=#


Of course PostgreSQL is open source, so I always recommend for folks to
do a test installation and test there apps out just to be on the safe
side.

Dear Robert Treat ,

First of all accept gratitude for answering the question

Post by Robert Treat
phppgadmin=# set autocommit = off;
ERROR: SET AUTOCOMMIT TO OFF is no longer supported
phppgadmin=#

Now does this mean that their must exist some PHP.INI file option that
will make client side auto commit on
But as such till now PHP version 4.3.4 their exist no such option till now
and defiantly we are testing our application for PostgreSQL 7.4 .
We would never like to miss the options provided by 7.4

Autocommit On is the default, you don't need any special options for it. If
you wanted autocommit off you would need a special option for that (which php
doesnt seem to have).
