Thanks to all give response to help.
This is my solution using the luanguage I familiar.(http://www.r-project.org).
I use the code to read a 11819x807 csv file and it takes 10 minus.I think is
not too slow .(My PC:1.7G,512M RAM)
#code begins
rm(list=ls())
f<-file("D:\\wvsevs_sb_v4.csv","r")#134M

Hm, there is a CSV reading module in Tcllib, so one could contemplate
using Tcl instead of Perl for this. That ought to take care of the
quotes
and other nastiness...
Perl's Text::CSV module available from CPAN also handles these issues.

Hello All,
Wouldn't it make sense to write a program that reads it in, one line
at a time, splits and inserts the data into the proper tables? Even
creating the table on the fly? That's what I'd do, a little command
line utility.
It's basically the "convert to SQL" technique you suggest where
I create an SQL file that has contents like this:
[EMAIL PROTECTED] elections]$ cat insert_precinct.sql
BEGIN TRANSACTION;
INSERT INTO "precinct" VALUES(1, 'Community Center 15 Crescent Road', 3,
'Greenbelt', 'Maryland', 0);
INSERT INTO "precinct" VALUES(2, 'Police Station 550 Crescent Road',
I have a very large CSV file with 1 rows and 100 columns.and the
file looks like the following:
"a","b","c","d",
"1","2","1","3" ,
"3","2","2","1",
..
If I use .import,It seems I have to set the variable names manually .
Is there any way to import the whole data file into SQLite quickly?
