Examine SessionAlias to see if a database component is using a session alias. If SessionAlias is true, a session alias is in use. If false, a session alias is not in use. 

A session alias is automatically created for a database component if it 

Uses the DriverName and Params properties instead of the AliasName property, and the Params property contains any parameters. 

Overrides Params values supplied by a BDE alias in AliasName. 

A session alias may also be created if an application permits the user to log into a server using a different user name than the one specified in the Params property. 

A session alias exists only while the application is running. It is not stored in the BDE configuration file, and cannot be accessed from outside the application.
