Verify support for named parameters in a CallableStatement

The JDBC specification provides the DatabaseMetaData.supportsNamedParameters() method to determine if the driver and the RDMS support named parameters in a CallableStatement. For example:
      Connection myConn = . . .   // connection to the RDBMS for Database
      . . .
      DatabaseMetaData dbmd = myConn.getMetaData();
      if (dbmd.supportsNamedParameters() == true)
      {
          System.out.println("NAMED PARAMETERS FOR CALLABLE"
                             + "STATEMENTS IS SUPPORTED");
          . . .
      }

The system returns true if named parameters are supported.
