External connection example code

The following is the source code for the methods used to make a connection. The source code can be found in the main method and the ASAConnect method of the file JDBCExamples.java in the ASIQ-12_6/Samples/ASA/JavaSQL/manual-examples directory under your Sybase IQ installation directory:

// Import the necessary classes

import sybase.sql.*;           // Sybase utilities
import asademo.*;              // Example classes

    }

    ASAConnect( "dba", "sql", machineName );
