Hi, I have set up a postgis database (PostgreSQL 9.3.6 on currently updated open Suse) and am trying to import some third party csv file. I did some basic sql a long time ago, but I was never an expert, and am now rusty :) In my "CREATE TABLE" command I am defining about 50 attributes / columns. Two of them are: ACCIDENT_DATE date, ACCIDENT_TIME time, My csv files generally have date and time values, but there are a number of NULL values represented as --,"",-- I expected / hoped that these would be imported as NULL values, but when I run the copy command, I get the error message - ERROR: invalid input syntax for type time: "" Can someone help me to get the empty double quoted value accepted as a NULL value for date and for time? TIA sql command: copy crashes FROM '/ACCIDENT.CSV' DELIMITER ',' CSV; Data Sample with "" time: "ACCIDENT_NO","ACCIDENT_DATE","ACCIDENT_TIME","ACCIDENT_TYPE","DAY_OF_WEEK","DCA_CODE","LIGHT_CONDITION","NO_PERSONS","NO_PERSONS_KILLED","NO_PERSONS_INJ_2","NO_PERSONS_INJ_3","NO_PERSONS_NOT_INJ","NO_OF_VEHICLES","POLICE_ATTEND","ROAD_GEOMETRY","SEVERITY","SPEED_ZONE","IMAGE_NO_DIGIT","IMAGE_NO_FRAME","IMAGE_RUN_NO","NODE_ID","LOCATION_TYPE","LOCALS_INVOLVED","NODE_ID","NODE_TYPE","LOCATION_TYPE","LOCATED_MIDPOINT","COMPLEX_INT_NO","AMG_X","AMG_Y","ROAD_NAME_1","ROAD_TYPE_1","ROAD_DESC_1","ROAD_ROUTE_1","ROAD_NAME_2","ROAD_TYPE_2","ROAD_DESC_2","ROAD_NAME_3","ROAD_TYPE_3","ROAD_DESC_3","DISTANCE_LOCATION","DIRECTION_LOCATION","NEAREST_KM_POST","OFF_ROAD_LOCATION","DIRECTORY","EDITION","PAGE","GRID_REFERENCE_X","GRID_REFERENCE_Y","LGA_NAME","REGION_NAME","UNKNOWN" "W1990000191","1989-12-19","","5",3,"183","5",1,0,1,0,0,1,"1","5","2","100",1518,1517,1050,18378,"N","Y",18378,"N","N","Y",0,648329.25,5958402,"GREAT ALPINE","ROAD","",4005,"UNNAMED","","","MCILROY RAE","ROAD","",73,"S",,"","VCD","ED7","35","C","9","ALPINE","NORTH EASTERN REGION",0 "P1990028638","1990-07-19","18:00:00","4",5,"183","5",1,0,0,1,0,1,"1","5","3","100",1828,1827,1086,18378,"N","Y",18378,"N","N","Y",0,648329.25,5958402,"GREAT ALPINE","ROAD","",4005,"UNNAMED","","","MCILROY RAE","ROAD","",73,"S",,"","VCD","ED7","35","C","9","ALPINE","NORTH EASTERN REGION",0 "P1990029504","1990-08-15","15:45:00","1",4,"130","1",7,0,0,4,3,2,"1","5","3","60",146,144,1097,18383,"N","N",18383,"N","N","N",0,654588.610512537,5951870.61325035,"MYRTLEFORD-YACKANDANDAH","ROAD","",5467,"MUMMERY","ROAD","","ODONNELL","AVENUE","",36,"SW",,"","VCD","ED7","660","C","3","ALPINE","NORTH EASTERN REGION",0 "P1990039075","1990-10-26","00:15:00","4",6,"181","5",4,0,1,3,0,1,"2","5","2","100",1666,1665,1102,18398,"N","Y",18398,"N","N","N",0,652283.479975146,5950175.41617511,"MERRIANG","ROAD","",177824,"TONIAZZO","LANE","","CRAMERI","LANE","",118,"NW",,"","VCD","ED7","49","D","3","ALPINE","NORTH EASTERN REGION",0
