feedback_7day, feedback_5day, feedback_3day, feedback_1day where l_date = 
'2015-09-09' and bid in ('949722CF_12F7_523A_EE21_E3D591B7E755') 
insert overwrite table portrait.test2 select iid, feedback_15day, 
feedback_7day, feedback_5day, feedback_3day, feedback_1day where l_date = 
'2015-09-09' and bid in ('test') 
insert overwrite table portrait.test3 select iid, feedback_15day, 
feedback_7day, feedback_5day, feedback_3day, feedback_1day where l_date = 
'2015-09-09' and bid in ('F7734668_CC49_8C4F_24C5_EA8B6728E394')
