I recently did this by parsing the data through a VB program that appended a “\” in front of any Char(10) and/or Char(13) characters which tells Postgres to accept the next character as a literal part of the column value I believe – must do because it worked! I also quoted the whole column as part of the VB prog…

 

Worked for me but I’m not sure the exact science behind it so someone else might be able to be of some more detailed help.

Subject: [SQL] Importing data from csv

 

Hi Folks,

sorry if this is a duplicate post, i've been tryin to find a solution of importing data into postgres from a csv file. The problem is, I have a database which consists of columns which contain newline characters (mac and unix). now when i export these files to a csv format, there are some line breaks (mixed unix and mac) in the data which breaks the copy procedure.

I also tried using the script posted in one of the previous posts..

#! /usr/bin/perl
$inquotes = 0;
while (<>){
     # Chop the crlf
     chop ($_);
     chop ($_);

     # this first bit goes through and replaces
     # all the commas that re not in  quotes with tildes
     for ($i=0 ; $i < length($_) ; $i++){
         $char=substr($_,$i,1);
         if ($char eq '"' ){
             $inquotes = not($inquotes);
         }else{
             if ( (!$inquotes) && ($char eq ",") ){
                 substr($_,$i,1)="~";
             }
         }
     }
     # this replaces any quotes
     s/"//g;
     print "$_\n";
}


cat data_file | perl scriptname.pl > outputfile.dat

and when i run the copy command i get messages like data missing for xyz column.
any possible hints.......
