Hi, I need some help with upsert. Some info on what I want to do: Each day I create a table for my firewall logs. I have one entry for one occurrence of all the field except sum, which is the number of occurrence I have of each log that match all the field. My table has the following field: firewall,action,src_zone,src_ip,dst_zone,dst_ip,proto,port,hex1,hex2,sum Each day I want to copy the last 7 days into one table so I have one table with the last 7 days of logs. So I want to copy the data from 7 tables into 1. If the row does not exist I just insert and if the row already exist I just update the sum (existing sum + new sum). Public.test is the table I use for the last 7 days logs. daily.daily_20131202 is table for 1 day. I will run this command 7 times with different daily table. WITH upsert as (update public.test T set firewall=S.firewall,action="" from daily.daily_20131202 S where (T.firewall=S.firewall and T.action="" and T.src_zone=S.src_zone and T.src_ip=S.src_ip and T.dst_zone=S.dst_zone and T.dst_ip=S.dst_ip and T.proto=S.proto and T.port=S.port and T.hex1=S.hex1 and T.hex2=S.hex2) RETURNING * ) insert into public.test select * from daily.daily_20131202 a WHERE NOT EXISTS (SELECT * FROM upsert b WHERE a.firewall=b.firewall and a.action="" and a.src_zone=b.src_zone and a.src_ip=b.src_ip and a.dst_zone=b.dst_zone and a.dst_ip=b.dst_ip and a.proto=b.proto and a.port=b.port and a.hex1=b.hex1 and a.hex2=b.hex2); When I run the command I get an error ERROR: column reference "firewall" is ambiguous LINE 3: ... a WHERE NOT EXISTS (SELECT * FROM upsert b WHERE b.firewall... Any idea what I am doing wrong? Also, is there an easier way to do that? Thanks for the help. |
