Please include the mailing-list in your replies, you'll get better help that way. Try to prevent top-posting as well, it makes it more difficult on people to get the context of your message and thus reduces the chance they'll answer - there's plenty more mail in this list ;) I'm not really sure what you're looking for, you didn't tell what you tried to see your data or what failed (and how) when you tried. The built-in commands in psql and pgadmin that I referred to don't show you your data, they show your data structure. You can query your data using SQL commands. I'm sure there are plenty of SQL tutorials around if that's what you're looking for? I'm guessing that if no error message was shown when you copied your data into the database, then you'll be able to see your data if you query your tables. None of us can tell you how to do that exactly, as we don't know your table structure, but you could get some general pointers (The SELECT statement is probably what you're looking for). Seeing your original message though, I wonder whether you did create any tables at all before you tried copying data into them? > -----Original Message----- > From: Alban Hertroys [mailto:dalroi@xxxxxxxxxxxxxxxxxxxxxxxxxxxx] > Sent: Saturday, November 13, 2010 6:12 AM > To: ray > Cc: pgsql-general@xxxxxxxxxxxxxx > Subject: Re: Basic Tutorials for 9.0 > > On 13 Nov 2010, at 3:44, ray wrote: > >> On Nov 10, 11:07 pm, robjsarg...@xxxxxxxxx (Rob Sargent) wrote: >>> ray wrote: >>>> I also tried the shell. create mydb.
