Re: PSQL return coder

Hello,

I am using PSQL to run SQL from a file with the -f flag as follows:

BEGIN
SQL
SQL
...
END

This gives me rollback on error and a nicer output than -1. This works fine.

My question is in a rollback scenario is it possible to get PSQL to return
a non 0 exit status?

Cheers,a
James

probably not - from psql perspective all statements was perfect

Maybe you could use -c instead of -f?

$ psql -c 'select 1; select 1/0' regression
ERROR: division by zero
$ echo $?
1

You won't need explicit BEGIN/END because this is already a single
transaction.

According to the man page,
"EXIT STATUS
psql returns 0 to the shell if it finished normally, 1 if a fatal error
of its own (out of memory, file not found) occurs, 2 if the connection
to the server went bad and the session was not interactive, and 3 if an
error occurred in a script and the variable ON_ERROR_STOP was set."

So for a longer script ON_ERROR_STOP might be the ticket (which is
usually a good idea anyways).

I was avoiding ON_ERROR_STOP because I was using ON_ERROR_ROLLBACK, but
have just realised that if I encase my SQL in a transaction then rollback
will still happen.

Perfect!
