I want to enter a .CSV file using COPY comand and plpgsql. It enters latitude,longitude and some data. In the CSV data there is no field (such as "user_name" or current_time) that allow distinguish future queries for different users (ex: select x,y from table where user_name=z; after entering lat,lon I would like to update the_geom in another table using the lat,lon of ONLY this user). I could update this kind of data ("user_name") using php but next user could not enter his data by COPY (it only lets fill the destination table if ALL the fields are the same as the CSV or text file). So, I have a problem. I thought that may be I can reference/select data of a SINGLE USER using parameters like default_time without need to insert this data as a field in the table (otherwise, problems with COPY). Maybe asking in catalog?
