Specifically, it fires after the Pre-Update trigger fires and before the Post-Update trigger fires, when Oracle Forms would normally update a record in the database.

However, JDBC is designed to enable vendors to supply drivers that offer the necessary specialization for a particular database. Therefore, you can create triggers just not row triggers to read and modify the parent and child tables. For example, if table p has three rows with the values 1 , 2 , 3 , and table f also has three rows with the values 1 , 2 , 3 , then the following statement updates p correctly but causes problems when the trigger updates f: This feature lets Java programs access Java objects stored in Oracle Database and application servers across the enterprise.
