Greenplum anonymous code block error?

Question

We have a schema in Greenplum with Postgres version 8.2, where we are not allowed to create a function. We have some working functions in another server/schema. We like to run those functions in a new schema as anonymous code block. We tried the following in pgadmin (Gui interface) and command line psql. We're getting an error.

Here is the tried code.

do $$
  declare
    at1 text;
    ftxt varchar(50) := ‘How are you?’ ;
  begin
    RAISE NOTICE ‘Hello World ‘ || ftxt ;
  end;
$$;

It is not accepting "do". That's where the error points. I need your guidance to make this work.

Is there a mechanism like DB link of Oracle to work with across greenplum instances/schema objects?

Answer 1

Greenplum isn't PostgreSQL, it's a separate product based on PostgreSQL 8.2.

DO was added in PostgreSQL 9.0. So this won't work on Greenplum. You must create then execute a function. If you don't have the rights to do that, you're just out of luck, you cannot use PL/PgSQL.

PostgreSQL supports DBLink (see dblink in the docs) for cross-database connections. I have no idea whether it's supported by Greenplum.

In future questions ensure that:

• You tag them greenplum as well as postgresql
• If you get an error, you give the exact text of the error message.

Thanks for including the code and mentioning that you were using PostgreSQL and Greenplum, though.
