Using the Ingres Demonstration Application
Ingres Demonstration Application
Ingres provides a sample transactional based application that demonstrates common programming tasks required to develop an application using Ingres.
The application shows how information is retrieved from Ingres and presented in a user interface control. Novice users can "borrow" code from the application to use in their own application development.
The demonstration application provides a working example of the main tasks required to insert, update, and retrieve data from an Ingres database, including:
SELECT queries that require parameters
Execution of a row producing procedure
Transaction commit and rollback
Use of Unicode character types
Handling of binary large objects (BLOBs)
