Hello,
is there any possibility to convert special columns during an CSV import
via COPY?
For example:
HELLO;WORLD;9999;011001
9999 should be converted to a character field
011001 to the date 10th January 2001
For the moment the only idea we have is, to import the CSV into a TEMP
table and
perform the conversion by a select from the temp to the target table.
I don't think there is; AFAIK the only option is the one you've outlined.
Ray.
On PostgreSQL 9.1, you can use File FDW to create a foreign table (that
is your CSV file).
Then you can use any kind of conversion allowed in the SELECT statement
There is an interesting article here:

Very easy to use.

Edson
