Not if you use an abstraction layer that does not do for instance data type
conversion. For instance, not all databases takes dates formatted in the
same way.
AFAIK, PEAR-DB is like Perl-DBI and so it does not support datatype
conversion and many other things important for assuring SQL code
portability.
Metabase and ADO-DB support datatype conversion.
