Returns the tenant name that is recorded in the client-principal object for an OpenEdge multi-tenant database. A tenant name is returned if this client-principal instance has been used to set the connection identity for the specified multi-tenant database. The association of this tenant name and multi-tenant database persists for this instance of the client-principal and cannot be removed for the duration of the user login session identified by this client-principal.
An optional character expression that evaluates to a case-insensitive logical or alias name of a multi-tenant OpenEdge RDBMS. This expression can be unspecified or evaluate to the Unknown value (?) only if the client-principal object has been used to establish identity for a single OpenEdge database connection.
The method can return the following values:
A recorded tenant name — If tenant information is stored in the client-principal for the database specified by db-exp
The Unknown value (?) — If no tenant information is stored in the client-principal for the database specified by db-exp
Blank ("") — If the database specified by db-exp does not have multi-tenancy enabled or the specified database has multi-tenancy enabled, but the client-principal object has not been used to set its connection identity
ABL raises ERROR if:
The client-principal object is in the INITIAL or FAILED state (see the LOGIN-STATE attribute entry)
The expression specified by db-exp evaluates to the Unknown value (?) and multiple OpenEdge databases are connected
A recorded tenant name — If tenant information is stored in the client-principal for the database specified by db-exp
