Hi all,

 

I am a Postgres-newbie and working on porting our code from Oracle to Postgres.

Oracle has a nice package procedure (dbms_output.put_line) to display a message in SQL*Plus, which can display a message to the user. I use this a lot, to notify users of the progress being made during the execution of a script.

Is there a way to do this with Postgres as well?

 

I have tried using ‘RAISE NOTICE’, but using this some extra lines are printed on screen. Those extra lines mess up the screen and will confuse the users. The extra lines shown are:

 

CONTEXT:  SQL statement "SELECT  migration_pkg.time_migration( $1 ,  $2 )"

PL/pgSQL function "check_migration" line 34 at PERFORM

 

Any help would be appreciated,

If you use the orafce module from pgfoundry, you get that same function.
