NAME
    Oracle::DML::Common - Common routines for Oracle DML

SYNOPSIS
      use Oracle::DML::Common;

      my %cfg = ('conn_string'=>'usr/pwd@db', 'table_name'=>'my_ora_tab');
      my $ot = Oracle::DML::Common->new;
      # or combine the two together
      my $ot = Oracle::DML::Common->new(%cfg);
      my $sql= $ot->prepare(%cfg); 
      $ot->execute();    # actually create the audit table and trigger

DESCRIPTION
    This class contains methods to create audit tables and triggers for
    Oracle tables.

   new ()

    Input variables:

      %ha  - any hash array containing initial parameters

    Variables used or routines called:

      None

    How to use:

       my $obj = new Oracle::DML::Common;      # or
       my $obj = Oracle::DML::Common->new;  

    Return: new empty or initialized Oracle::DML::Common object.

    This method constructs a Perl object and capture any parameters if
    specified.

METHODS
    The following are the common methods, routines, and functions used by
    other classes.

  Connection Methods

    The *:db_conn* tag includes sub-rountines for creating and managing
    database connections.

      use Oracle::DML::Common qw(:db_conn);

    It includes the following sub-routines:

   get_dbh($con, $dtp)

    Input variables:

      $con - Connection string for
             Oralce: usr/pwd@db (default)
                CSV: /path/to/file
           ODBC|SQL: usr/pwd@DSN[:approle/rolepwd]
      $dtp - Database type: Oracle, CSV, etc

    Variables used or routines called:

      DBI
      DBD::Oracle
      Win32::ODBC

    How to use:

      $self->get_dbh('usr/pwd@dblk', 'Oracle');
      $self->get_dbh('usr/pwd@dblk:approle/rpwd', 'SQL');

    Return: database handler

    If application role is provided, it will activate the application role
    as well.

   is_object_exist($dbh,$tn,$tp)

    Input variables:

      $dbh - database handler, required.
      $tn  - table/object name, required.
             schema.table_name is allowed.

    Variables used or routines called:

      echoMSG    - display messages.

    How to use:

      # whether table 'emp' exist
      $yesno = $self->is_object_exist($dbh,'emp');

    Return: 0 - the object does not exist; 1 - the object exist;

  Table Methods

    The *:table* tag includes sub-rountines for creating, checking and
    manipulating tables.

      use Oracle::DML::Common qw(:table);

    It includes the following sub-routines:

HISTORY
    * Version 0.1

        class and formed Oracle::DML::Common.

    * Version 0.21
        Remove get_table_definition method to *Oracle::Schema* class.
