From the above input I would like to take table_name.column_name format output. but default null is not the column name. keeping that in mind I would like to get a regex to do this. I have written a perl code which comes for 20 lines. to do the above task. But I would like to get the better solution.
The out put should be as follows 
vodafone_capacity_cell_count_week
vodafone_capacity_cell_count_week.nc_id
vodafone_capacity_cell_count_week.cell_id
vodafone_capacity_cell_count_week.week_of 
vodafone_capacity_cell_count_week.busy_hour
vodafone_capacity_cell_count_week.gsm_tch_cong_pc_range_1 
vodafone_capacity_cell_count_week.gsm_tch_cong_pc_range_2 
vodafone_capacity_cell_count_week.gsm_tch_cong_pc_range_3 
vodafone_capacity_cell_count_week.gsm_sdcch_cong_pc_range_1
vodafone_capacity_cell_count_week.gsm_sdcch_cong_pc_range_2
vodafone_capacity_cell_count_week.gsm_sdcch_cong_pc_range_3
vodafone_capacity_cell_count_week.gsm_sdcch_cong_pc_range_4
vodafone_capacity_cell_count_week.gsm_hr_tch_util_pc_range_1
vodafone_capacity_cell_count_week.gsm_hr_tch_util_pc_range_2
vodafone_capacity_cell_count_week.gsm_hr_tch_util_pc_range_3
vodafone_capacity_cell_count_week.gsm_hr_tch_util_pc_range_4
vodafone_capacity_cell_count_week.gsm_hr_tch_util_pc_range_5
vodafone_capacity_cell_count_week.gprs_cong_pc_range_1
vodafone_capacity_cell_count_week.gprs_cong_pc_range_2 
vodafone_capacity_cell_count_week.gprs_cong_pc_range_3
