Here is a simple way to import a tab delimited.
cat file.tab | psql -c "copy table1 from stdin;" database1
And now for a comma delimited file.
cat file.cvs | psql -c "copy table1 from stdin using delimiters ``,'';"
database1
CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION
CAUTION CAUTION
CAUTION make sure their are NO SINGLE '\' characters CAUTION
CAUTION CAUTION
CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION CAUTION
The ``\'' character is an escape character.
To fix this automatically use a sed command like this.
sed -e "s;\\\;\\\\\\\;g" file.tab | sql -c "copy table1 from stdin;"
database1
You will also need to make sure any caracter in your data that is also
your
delimiter is escaped. For tabs escape tabs in the data with ``\ ''.
For comma's escape with ``\,''.
Escaping tabs can be difficult using a bash shell, you can do it within
a script.
This works for me.
