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,[email protected]

2500,Armando Guajardo,2500DATA,[email protected]

3500,AAA,3500DATA,[email protected]

3700,Armando Juan ,3700DATA,[email protected]

4500,padawan,4500DATA,[email 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
