Hi, I try to derive two classes from DBI with the following code:

use strict;
use warnings;
use DBI;

BEGIN{
  package MyDBI;
  our @ISA = ('DBI','MyDBI::st');

  sub connect {
    my $class=shift;
    my ($db,$user,$pw) = @_;
    my $self = DBI->connect($db,$user,$pw, { RaiseError => 1  } );
    bless $self;
    return $self;
  }
}

# ----------------------------------------
BEGIN {
  package MyDBI::st;
  our @ISA = ('DBI::st');
  
  sub query {
    my $class = shift;
    my $self = $class->prepare("SELECT * FROM `table` LIMIT 2");
    $self->execute();
    bless $self;
    return $self;
  }
}

my $dbh = MyDBI->connect("x","y","z"} );
my $sth = $dbh->query();

and perl gives the answer:

Can't locate auto/MyDBI/prepare.al in @INC (@INC contains ....) at lin
+e DB.pm line 29
[download]

I tried a couple of things, including using SUPER:: and different settings of @ISA but I don't find a solution. Thanks for your help, Jan

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
