Porting from PL/SQL to PLPGSQL

Hi All,

We are in the process of migrating of our application from Oracle to
PostGreSQL.


we are  facing a few problems with PL/SQL Code..


1)    In Oracle sqlplus we can run sql script files as @script_name;How do we do the same in PostGres.Also is there any
replacementfor "&&" in PostGres ?
 

Eg:    CREATE USER CATALOG    IDENTIFIED BY &ORA_PASSWORD    DEFAULT TABLESPACE &DFLT_TABLESPACE    TEMPORARY
TABLESPACE&TEMP_TABLESPACE
 


2)     In PostGres a function can not take more 16 arguments.We have some
procedures which are taking more than 16 arguements.So how can we convert them into PostGres.



Can anyone give some valuable suggestions..


Regards

Joe.

psql takes \i. See psql's \?

See the "Porting From Oracle PL/SQL" document I wrote that is part of the
PL/pgSQL documentation.

What does that do?

You can recompile to change the number of parameters.
PG 7.3 can have up to 32 arguments by default, IIRC.

Hi..

In postgres, you have two options..

From PSQL prompt, you can use " \i filename " to process the file..
OR from PSQL prompt, you can directly instruct to execute that file like..
psql ... --filename <<your_file_name>>

Basically, when "&&" is specified in PL/SQL scripts, it prompts the user to
enter its value. In Postgres, we do not have such option (so far i know).
So, you can replace those with your desired values directly.

Postgres supports Array type too. Although i haven't used it anyday.. you
can try it out.
