Обсуждение: psql and autocommit

Hi all!
I am using 7.3.4
while executing psql -c the query is not commited
that is probably because i have setted the autocommit = false
However that is very unheandy - i have to add begin and
commit to my shell scripts.I beleave that automatically
commiting the psql -c queries is very logical thing.
Is there a way to avoid this ?
If that is not changed in 7.4  maybe it should be in
future versions?
Thanks.

I'm sure there are people who disagree with that statement. For instance
Oracle's sqlplus starts in noautocommit by default. And I've found that to be a
good thing actually.
For what it's worth I also think default client policy may as well be left
unchanged, or there will be a lot of baffled people.

Probably a metter of taste.

You are right.But there is no even a simple flag for psql
that will tell it to do autocommit!(maybe i will manage to use -set
but i don't know how for now).

You have found one of the reasons we decided server-side autocommit was
evil ...

Use 7.4.  Note that autocommit is a psql feature not a server setting
in 7.4.

Just a note to clarify sqlplus

It does start in noautocommit as you say.
However,  it issues a commit when you exit (with quit, Ctrl-D or whatever)
which is (in my opinion) incorrect, and very much worth taking into account
when writing scripts for Oracle.
I think it should automatically issue a rollback on exit.

regards,

Stephen.

You are all right .However i was talking about the writing
shell scripts and running
psql -c
from it .THIS is a big problem if no autocommit is setted on
since at the end of the psql -c command there is a disconnect
and you have to add a commit to it BEFOR this disconnect.very
unhandy .
However i understood from Tom that this is solved in 7.4 ,
just not yet ready to switch to it from my 7.3 server.
Thanks
