Implicit Connection to an SQL Database

      Disclosed is a method of establishing an implicit connection
between a database client application and a predetermined database.

     Many database products provide a "default" database, to which a
user is always connected.  The Extended Services* Database Manager
does not provide this, which poses a code compatibility problem for
users.  We have solved this problem by providing a form of implicit
connection to a database.

     Currently, when an SQL statement is issued in the Extended
Services Database Manager, the issuing application must already be
connected (via a START USING DATABASE request) to a database, or an
error will be returned.  The program flow is as follows:
 APPLICATION               BASE SERVICES UTILITIES (BSU)
 issues SQL request

      ------------------------->

                          Is application connected?
                          YES:
                             route request ----------------->
                          NO:
                             issue error
 With Implicit Connection, the following occurs instead:
 APPLICATION               BASE SERVICES UTILITIES (BSU)
 issues SQL request

      ------------------------->

                          Is application connected?
