Обсуждение: Selecting more columns in ECPG in one select - error?

    Hi all,

I have one trouble.. I have this stable:
create table t (col1 varchar (10), col2 varchar (10), col3 int);

and now, I would like this:
exec sql select col1 into :str1, col2 into :str2 from t where col3 = :cislo;

ECPG distributed with PostgreSQL 6.4.2 say: parse error.

    In the older version ECPG, distributed in winter 1997 (I think PGSQL
6.0..?) I use this syntax without errors.

In PSQL I can do also this: select col1, col2 from t where col3 = <number>;

    Is this error in yacc definition and will be fixed in version 6.5, or
nobody know this error?

Please correct me if I'm wrong but IMO the correct syntax is:

exec sql select col1, col2 into :str1, :str2 from t where col3 = :cislo;

Yes, that old version did not really check the syntax.

I think the 1997 version is the buggy one.
