Declaration

TnxDatabaseMapper = class(TnxStateComponent)

 
Description

Component that wraps a collection of database connections. The collection is used to create a unique namespace from database aliases that are not necessarily unique, for instance if you have the same aliasname in both a local and remote server, and want to use a report engine that needs database name uniqueness (e.g. ReportBuilder).

There are two ways of creating the collection; either set the DefaultSession property, which reads in the list of databases connected to the session, or create entries in the Mappings collection.
