Error with REF. Forms and RDB

[Javier Coego]

- Hi, all. -

- I have Developer 2000 - Forms Builder and RDB 7.1. - I'm trying to
create a form with a Master-Slave relation between two tables joined
by a varchar column. -

- Anyway, by hand or using the Wizards, when I try to get data it
raises the following error:

%SQL-F-RTNNOTDEF, function or procedure REF is not defined

- The "wrong" query always recovers, among others, a column with
REF(table_alias). - There are some REF references which I can change
by hand, but there are other which I cannot access (I suppose queries
which are generated and hidden by Forms Builder). -

- What does REF function do???? - (It seems that returns a pointer to
the table/column or returns the primary key for the corresponding
table)

- Does RDB support the REF function??? -

- Any idea to solve this problem??? -

- Thanks in advance. -

- Kind regards. -
