using COPY, .CSV and ¿catalog?
Hi everybody,
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?
Thanks,
Pere

I'm not a 100% certain I understand what you're trying
to achieve, but to me this looks like a mis-use? Why
not use the relational features of your RDBMS and just
pick a location from a table created once via a unique
value you assign during (or after) the COPY?
Thanks,
