Detailed Description

Error Class.

Library: dataccess

The IliErrorMessage class is used to describe errors that occur during program execution. Errors may originate from different sources, such as the database server, the database client library, the Rogue Wave Views DB Link library, the Rogue Wave Views Data Access library, or the application itself. Each error message holds an error code whose meaning depends on the layer that triggered the error, and some descriptive text.
