Abstract
A query object generator tool which generates interface definitions and code that implement a query object also generates a database schema access query object that retrieves the schema of an underlying database. Instead of retrieving data from the database, the database schema access query object retrieves “metadata”, including the names of tables and stored procedures in the database and their descriptions, from the database. The metadata is then displayed as part of a graphic user interface which is used to construct the SQL query implemented by the query object. In accordance with one embodiment of the invention, the database schema access object also verifies that an SQL query generated by a user is valid by submitting the query to the database engine of the underlying database. In accordance with another embodiment of the invention the database schema access object contains methods which perform automatic mapping of “standard” SQL data types to vendor-specific data.
