correct me if i'm wrong (and in that case please explain what you DB_GET function returns), but i believe this is just:
use DBI;
my ($db_name,$host_name,$port,$db_user,$db_pass,) = @_;
my $database = "DBI:mysql:$db_name:$host_name:$port";
my $dbh = DBI->connect($database,$db_user,$db_pass);
my ($table, $col, $value) = ('clients', 'client_id', $client_id);
my $sql = "select * from $table";
if( $value ){
$sql .= " where $col = ?";
push @bind, $value;
}
my $href = $dbh->selectall_hashref($sql, $col, {}, @bind);
I'm not sure exactly though.. it doesn't appear to me that your code works if trying to select out all the rows.. But be sure to read through the
DBI docs (
perldoc DBI) and look at all the
select* methods available.
Other modules to be aware of:
SQL::Abstract,
Class::DBI,
Class::DBI::Autoloader
