Thread: Oracle Package equivalent in Postgres
Hi Postgres master minds,
Am currently working on migrating databases from oracle to Postgres.
Am going to work on crons and packages in oracle which needs to be converted in Postgres. How to convert package in oracle to Postgres. Is there any equivalent in Postgres if not how it works in Postgres.
Eagerly waiting for replies.
Thanks
Hi, It depends on what you want to achieve with using packages. If you just want to group a number of functions and procedures, just create a schema for it (schemas are totally unrelated to users in PostgreSQL), e. g. CREATE SCHEMA functions; and then CREATE FUNCTION functions.f1 (integer) RETURNS integer LANGUAGE plgpsql AS $$ ... $$; Unfortunately, there are no schema related variables. You will have to resort to saving values in some (temporary, unlogged, normal) table. There is another way of using a setting as a variable described here: https://dba.stackexchange.com/questions/165361/assign-the-result-of-current-settingthe-setting-to-a-variable-in-pl-pgsql/165372#165372 Regards, Holger Am 06.08.20 um 14:22 schrieb Firthouse banu: > Hi Postgres master minds, > > Am currently working on migrating databases from oracle to Postgres. > Am going to work on crons and packages in oracle which needs to be > converted in Postgres.

Hi, ora2pg is a standard way to migrate stuff from ORA to PG. It also will attempt to translate packages/procs/funcs from PL/SQL to PL/pgSQL. For packages, the output can be separate files with package_name_func/proc_name, or you can group packages into separate output directories where you can subsequently load them into separate PG schemas to distinguish one ORA package from another.

Good info Michael,
I used ora2pg tool to migrate Oracle DB objects (particularly tables, constraints, sequences) into Postgres.
The TYPE attribute of ora2pg will tell if the DDL need to migrate or the Data or any other export type.
The TYPE attribute of ora2pg will tell if the DDL need to migrate or the Data or any other export type.
Though I have not explored any other tools, I found ora2pg is very efficient and this can be automated either using windows batch script or unix shell script.

Hi,
ora2pg is a standard way to migrate stuff from ORA to PG. It also will
attempt to translate packages/procs/funcs from PL/SQL to PL/pgSQL. For
packages, the output can be separate files with
package_name_func/proc_name, or you can group packages into separate
output directories where you can subsequently load them into separate PG
schemas to distinguish one ORA package from another.
