Unless you're using Object-Relational mapping tools, its pretty hard not to hard-code SQL statements and most solutions that get around this do so in an un-manageable way. For example, you can have every query in a single properties file and/or attached to a stored procedure but the long term maintenance tends to lead to out-of-date and confusing code. Why do you want the table names to be dynamic? In practice, database changes are significantly less common than code changes.
