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. 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.
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)
