        PARAMS: 
                SEQUENCE_NAME => sequence name for generate ID for insert  
                DB_CONN       => DBI instance

get_connection - return the value of DB_CONN param

get_sth - return the handle of the prepared statement

get_clone - return the clone of the object

get_next_sequence - return the next value of SEQUENCE_NAME

        PARAMS: 
                SEQUENCE_NAME - sequence name for generate ID for insert (default the valiue of the same param in the constructor)

        the second argument is  a id value
        the method return  the number of rows deleted if id value exist else return undef

query_rows - return rows reading a table

        the first argument is a table object generate from blx::xsdsql::parser::parse
        the second argument is  a id value
        in scalar mode the method return a pointer of an array 
        in array mode  the method return an array

get_binding_columns - return the columns with a value binding

get_query_prepared - return the current query prepared

finish - close the prepared statements

        this method return the self object
