Database Triggers

Triggers can be created for IBM^® Informix^® database tables with the CREATE TRIGGER instruction.

If you plan to support different types of database servers, you must be aware that each DB vendor has defined its own trigger creation syntax and stored procedure language. In such cases, you may consider writing most your business logic in BDL, and implementing only some triggers in the database, mainly to get better performance or use database features that only exist with stored procedures.

Genero BDL partially supports trigger creation:

• The Genero BDL static SQL syntax does not include the CREATE TRIGGER and DROP TRIGGER instructions. However, you can create database triggers by using dynamic SQL (EXECUTE IMMEDIATE).
