Обсуждение: plpgsql question - simple I would have thought

This should be simple, but it's not. I think I'm just missing something
simple.  I converted an oracle PL/SQL program to plpgssql, but it wouldn't
work, so I tried some very simple blocks, and even they fail. As far as I
can tell, the syntax is all valid.

Any help?


(postgres) robux:/opt/postgres/VRNJED
->cat it.sql

\echo raise notice attempt
begin
  raise notice 'hello';
end;

\echo select into attempt
declare
  i_int integer;
begin
 select count(1) into i_int from vrnsys_version;
end;

(postgres) robux:/opt/postgres/VRNJED
->psql -U vrnsys

PL/pgSQL is for writing user-defined functions, so you need some
CREATE FUNCTION statements.

That version is pretty old -- if you must use 7.3 then at least
consider upgrading to 7.3.9.  See the Release Notes for a summary
of bug fixes and other changes:

http://www.postgresql.org/docs/7.3/interactive/release.html

If you're not committed to using 7.3 then you might want to check
out 8.0.2 when it's released (which should be Real Soon Now).
