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
