Обсуждение: EXECUTE SELECT INTO... last one!

PgSql8.1beta2 gives me this:

ERROR:  EXECUTE of SELECT ... INTO is not implemented yet
CONTEXT:  PL/pgSQL function "_rndbroj" line 5 at execute statement

Shall I forget about this once and for all (and use FOR construct), or
there is a chance that will be 'fixed'?

Could you post a simple example of what you're trying to do?  The
following works for me in 8.1beta2 (from CVS):

CREATE FUNCTION mycount(text) RETURNS bigint AS $$
DECLARE   query  text;   cnt    bigint;
BEGIN   query := 'SELECT count(*) FROM ' || quote_ident($1);   EXECUTE query INTO cnt;   RETURN cnt;
END;
$$ LANGUAGE plpgsql;

SELECT mycount('pg_class');mycount 
---------    188
(1 row)

Yes, it's my fault. I was testing it on pg7.4. On 8.1beta2 works as you
explained. Though it would be realy nice to be able to do 
var := col FROM tempTable WHERE condition

withouth EXECUTE'ing and stuff.

Sorry for the fuss I might have created.
