back-sql Varchar2 Primary Key Support

[King, Leon C]

Hi all,
        
        Is there a way to wrap oracle functions to where clauses passed
into back-sql?  I have a non-numeric primary key value of my users'
table which in some cases is preceeded by a '0'.  None of the data
mapped via the ldap_entries.keyval and my table are being retrieve when
I execute an ldap search.  If I remove the preceeding '0' the values are
retrieved.

Thanks,

Leon King
