Techniques for developing database applications are described herein. According to one embodiment, an object-relational mapping (ORM) query language (OQL) statement is received via a first window which is entered from a user for querying an underlying database, where the OQL statement is written in a customized query language that is incompatible with the underlying database. In response, a SQL statement compatible with the underlying database is dynamically displayed in a second window, where the SQL statement is automatically translated from the OQL statement displayed in the first window. Other methods and apparatuses are also described.
