That's not a good approach. There is no point in abstracting calls to
the database, as the bulk of the differences between databases lies in
the sematics of the queries. What you really want to do is abstract the
entire data retrieval process. You application code doesn't need to
know that it's getting its data from a database. The data just needs to
be coming from somewhere: a MySQL database, a MS-SQL database, an
XML-file, or even a SOAP-compatible web-service. If your application is
agnostic in regards to data source, then it's automatically database
independent.
