hello again!!
I have right now a problem I have a program to pick up data from a DBF and then convert all data to CSV,
and then with the data on a CSV put it in a table in MySql
but the problem facing right now is this :
DBD::CSV::db do failed: Can't call method "fetchrow_array" on unblesse
+d 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 20.
DBD::CSV::db do failed: Can't call method "fetchrow_array" on unblesse
+d reference at C:/Perl/site/lib/SQL/Statement/Functions.pm line 560.

+/SQL/Statement.pm line 264.
[for Statement "SELECT * FROM IMPORT (?)"] at testdbf4.pl line 20.
And this is where the program stops everytime :
while ( my $row = $sth->fetch) {
print "data es $row->[2].csv\n";
$dbhC->do("CREATE TABLE $row->[2] AS IMPORT(?)",{},$select);
this is the full code of the program :
#!/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) {
print "data es $row->[2].csv\n";
$dbhC->do("CREATE TABLE $row->[2] AS IMPORT(?)",{},$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]'
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]")
{
print "Advertencia el archivo existe iniciando el borrando del mis
+mo ";
unlink ('c:/proyecto/$row->[2].csv');
}
}
This a very important program for me I hope you can help me
Thanks :o)
