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 });` [download]	[reply] [d/l]

If you are the one to create the database, why don't you just set a user and password?	[reply] [d/l]

You should always have a password set for any logins to a dbms even if it is just you accessing the database. Jason L. Froebe Blog, Tech Blog	[reply]

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?	[reply]

Have you tried using `undef` or `''` for the username and/or password?	[reply] [d/l] [select]

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. Regards, Karl ŤThe Crux of the Biscuit is the Apostropheť	[reply]
