Need help 2007-10-19 - By Armando Gomez

I am working on getting data from a DBF and saving it on a CSV file and then
putting it on MySql
The program work great when it is only one but now I need to make the
program go look to a CSV file
And get from there the filenames this is the CSV file :
1458,juan armando,1458DATA,armano@(protected)
2500,Armando Guajardo,2500DATA,a5026@(protected)
3500,AAA,3500DATA,ar@(protected)
3700,Armando Juan ,3700DATA,armzg@(protected)
4500,padawan,4500DATA,padawan@(protected)
The filename is the 3rd Column
So I try to get them by an array
my $dbh = DBI->connect("DBI:CSV:f_dir=/Proyecto/")
or die "Cannot connect: " . $DBI::errstr;
my $sth = $dbh->prepare("SELECT * from patentes.csv")
or die "Cannot prepare: " . $dbh->errstr();
$sth->execute() or die "Cannot execute: " . $sth->errstr();
while ( my $row = $sth->fetch) {
but it give me an error message like this
DBD::CSV::db do failed: Can't call method "fetchrow_array" on unblessed
reference at C:/Perl/site/lib/SQL/Statement/Functions.pm line 560.
Can't use an undefined value as an ARRAY reference at
C:/Perl/site/lib/SQL/Statement.pm line 264.
[for Statement "SELECT * FROM IMPORT (?)"] at testdbf4.pl line 19.

This is complete code
#!/usr/bin/perl
use warnings;
use strict;
use DBI;
#---- This part conects to my 2 databases one CSV and one XBase -- --
my $dbhX = DBI->connect('dbi:XBase(RaiseError=1):');
my $dbhC = DBI->connect('dbi:CSV(RaiseError=1):');
my $select = $dbhX->prepare("SELECT * FROM reg501");
$select->execute();
#--- This one to the table on CSV where I have the data -- ---
my $dbh = DBI->connect("DBI:CSV:f_dir=/Proyecto/")
or die "Cannot connect: " . $DBI::errstr;
my $sth = $dbh->prepare("SELECT * from patentes.csv")
or die "Cannot prepare: " . $dbh->errstr();
$sth->execute() or die "Cannot execute: " . $sth->errstr();
while ( my $row = $sth->fetch) {
$dbhC->do("CREATE TABLE $row->[2].csv AS IMPORT(?)",{},$select);
my $mysql_dbh = DBI->connect("DBI:mysql:database=test;host=localhost",
"root", "xyz123",
{'RaiseError' => 1});
#---- Here I empty the table in MySql -- ---
$mysql_dbh->do("TRUNCATE TABLE $row->[2]");
#---- Here I load all the data -- ----
my $sql = "LOAD DATA LOCAL INFILE 'c:/proyecto/$row->[2].csv'
INTO TABLE $row->[2]
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'";
my $sth = $mysql_dbh->prepare($sql);
$sth->execute ();
if (-e "c:/proyecto/$row->[2].csv")
{
print "Advertencia el archivo existe iniciando el borrando
del mismo ";
unlink ('c:/proyecto/$row->[2].csv');
}
}
Can someone help me?
Thanks
