Using DB->connect for mysql db without password

angeloulivieri has asked for the wisdom of the Perl Monks concerning the following question:

How can I do the thing in the title?

I've been googleing it for a lot of time but it seems that there's no way to access a database where no password has been set.

In example I use this form to create a db:

 $drh->func("createdb", $database, $host, $mySqlUser, $mySqlPass, 'admin');

and it works.


but what about if I don't have user and password for my mysql?

This one for sure don't work...

 $drh->func("createdb", $database, $host, 'admin');

    Having databases without passwords is a bad idea, but if you really must do it the following code works for me.

    my $database = 'test'; my $dbh = DBI->connect("DBI:mysql:$database",undef,undef,{ RaiseError +=> 1 });

    If you are the one to create the database, why don't you just set a user and password?

    You should always have a password set for any logins to a dbms even if it is just you accessing the database.

      I don't want to appear stupid... :D

      My problem is that I'm creating a software that does some analysis based on the use of a MySQL database. Now, I installed this program on a machine where I seen that mysql can be accessed without any pwd and usr. So I was wondering: "what if the user didn't set these two parameters?".

      I'm going crazy searching for an answer. I think now that this is not a possible situation with PERL DBI... is it true?

        Have you tried using undef or '' for the username and/or password?

        What software are you using, exactly? You don't seem to call DBI->connect, but rather a connect method on a different object. What kind of object is it?

        Usually connecting to mysql without user name and without password only works if you don't specify a host name either (not even localhost), then local domain sockets are used, and the identity of the system user is used.

    Please, give your mySQL database a password and the appropriate permissions, it's best practice.

    This ugly "no password approach" at basic setup is IMHO one of the sickest quirks of mySQL.
