# DatabaseQuery Finders

Previous

Next

Finders that use a `DatabaseQuery` lets you create dynamic queries that you generate at run time rather than at deployment time.

In addition to finders that take a `DatabaseQuery`, TopLink also provides a default `findAll` finder that returns all the EJB of a given type. As with other dynamic finders, the TopLink runtime reserves the name `findAll`.

For more information, see "Database Queries".

For more information on TopLink predefined finders that take a `DatabaseQuery`, see "Predefined Finders".
