Re: CSV import

Hi

You will need two text utilities {dos2unix and sed} to do this in the simplest 
way. They are fairly standard text utilities and are probably already on your 
machine.

This is how I would do it :

sed "s/\"//g" file_name.txt \| dos2unix \| pgsql -c "COPY table_name FROM STDIN USING DELIMITERS ',';" db

Where "file_name.txt" is the csv file you want to import and "table_name" is 
the previously created table you want to insert the data into and db is the 
database name.

How this works is "sed" {stream editor} removes all the double quote 
characters '"' then pipes the output through "dos2unix" which converts all the 
CRLF {DOS EOL} sequences into CR {UNIX EOL} characters, then pipes the data to 
"pgsql"  with a command that does a bulk insert into the table of the database 
you have selected.
