There isn't really any way to get around specifying the columns. I wrote a tool to help import files into the database, you could probably make use of it: https://github.com/f0rk/csv2table Assuming the table already exists and your csv has columns with the same names as the columns in your table: csv2table --file /path/to/your/file.csv --no-create --copy --backslash | psql If the table doesn't exist, you could do: csv2table --file /path/to/your/file.csv --copy --backslash | vipe | psql And edit the create statement to add a SERIAL column (the copy command will specify all of the columns in the file for you). It's a 95% solution I use to get delimited files into the database. It's not perfect but it works most of the time. If you have any issues or feature requests feel free to open an issue on github. -Ryan Kelly On Tue, May 6, 2014 at 4:22 PM, David G Johnston <david.g.johnston@xxxxxxxxx> wrote: > So, I am trying to import a file into a table and want to assign a sequence > value to each record as it is imported. > > I know that I can pre-process the input file and simply add the needed data > but I am curious if maybe there is some trick to having defaults populate > for missing columns WITHOUT explicitly specifying each and every column that > is present? > > Thanks! > > David J. > > > > > -- > View this message in context: http://postgresql.1045698.n5.nabble.com/any-psql-copy-tricks-for-default-value-columns-without-source-data-tp5802795.html > Sent from the PostgreSQL - general mailing list archive at Nabble.com. > > > -- > Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) > To make changes to your subscription: > http://www.postgresql.org/mailpref/pgsql-general -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
