Question

I am trying to insert multiple values to the same field using a single query. Are there any mistakes in the following code?

my $dbh =  DBI->connect("DBI:mysql:accounting:localhost", 'username', 'password',
      {RaiseError => 1});
my @id = [1,18,976,90];
my @name = ['ss','dc','ws','rd'];
my @data = ([@id],[@name]);
my $ab = $dbh->prepare("insert into table (id,name) values (?,?)";);
for my $datam (@data) {
  $ab->execute(@$datam);
}
$ab->finish();

I am getting the following error: DBI::st=HASH(0*a16f774) for prepare statement. What could be causing this?

Can’t really answer your question since you didn’t actually give the error, but I have spotted a problem with your code. You’re doing

$ab->execute([1,18,976,90]);
$ab->execute(['ss','dc','ws','rd']);

when you obviously want to do

$ab->execute(  1, 'ss');
$ab->execute( 18, 'dc');
$ab->execute(976, 'ws');
$ab->execute( 90, 'rd');

Fix:

my @id = (1,18,976,90);
my @name = ('ss','dc','ws','rd');

for my $i (0..$#id) {
   $ab->execute($id[$i], $name[$i]);
}
