connect to MySQL from Perl using DBI
Hi,
I want to connect perl with the mysql to select and so on but the connection don't work
code
PHP Code:
#!/usr/bin/perl
BEGIN {
# PERL MODULES WE WILL BE USING
use DBI;
$dbh = DBI->connect('DBI:mysql:C:\Program Files\MySQL\MySQL Server 5.0\data\db1','','pass') or die $DBI::errstr;}
# (insert query examples here...)
$sth = $dbh->prepare('SELECT gene_name FROM protein_names );
$sth->execute();
$result = $sth->fetchrow_hashref();
print "Value returned: $result->{description}\n";
end{
$dbh->disconnect();
}
I want from this code to get all gene_name in the table and put them in a hash table.
Note:
PHP Code:
$dbh = DBI->connect('DBI:mysql:C:\Program Files\MySQL\MySQL Server 5.0\data\db1','','pass') or die $DBI::errstr;
here i defined the path to the db file and pass is the password i set to the mysql when i treat with and i didn't use a user name for this database
Thanks in advance

dbix::class::storage::dbi::mysql
DBIx::Class::Storage::DBI::mysql(3pm) User Contributed Perl Documentation DBIx::Class::Storage::DBI::mysql(3pm)
NAME
DBIx::Class::Storage::DBI::mysql - Storage::DBI class implementing MySQL specifics
SYNOPSIS
Storage::DBI autodetects the underlying MySQL database, and re-blesses the $storage object into this class.
my $schema = MyDb::Schema->connect( $dsn, $user, $pass, { on_connect_call => 'set_strict_mode' } );
DESCRIPTION
This class implements MySQL specific bits of DBIx::Class::Storage::DBI, like AutoIncrement column support and savepoints. Also it augments
the SQL maker to support the MySQL-specific "STRAIGHT_JOIN" join type, which you can use by specifying "join_type => 'straight'" in the
relationship attributes
It also provides a one-stop on-connect macro "set_strict_mode" which sets session variables such that MySQL behaves more predictably as far
as the SQL standard is concerned.
STORAGE OPTIONS
set_strict_mode
Enables session-wide strict options upon connecting. Equivalent to:
->connect ( ... , {
on_connect_do => [
q|SET SQL_MODE = CONCAT('ANSI,TRADITIONAL,ONLY_FULL_GROUP_BY,', @@sql_mode)|,
q|SET SQL_AUTO_IS_NULL = 0|,
]
});
