adding DSN to a machine

[Anonymous Monk]

I have played around a bit with Win32::ODBC and have been quite successful. My issue now is I want to create a standalone app that will run on a given users machine, problem is not all machine have the DSN for the database added. I don't want to walk around to all the machine to add it, is there a way to add it from perl code?

Does anyone know if Win32::ODBC supports ADO? If it does, you can set up your connection string to be DSN-less.

For example, for an access database, you'd set up the connection string as follows..

"DBQ=C:\path\to\you.mdb;DRIVER={MS Access (*.mdb)}"

and for an MS SQL connection..

"Provider=SQLOLEDB; Data Source=Server_Name; Initial Catalog=DatabaseName; User ID=UserID; Password=Password"

This way you won't have to install DSN's on any of the machines. There's a bunch of debaet over performace.. some people saying that it's better DSN-less and others saying it's slower. I can't weigh in on that, but it will help you with you problem..

Hope this helps..

UPDATE The first example is NOT ADO. It should work regardless of whether or not Win32::ODBC supports ADO though... it's just a standard DSNless connection. There's an ADO method to connect to access database also. If you need more info on any of this, let me know and I'll dig up some more info.

You don't even need to add a DSN to each machine. As you can see in the Win32::ODBC docs, you can use a connection string instead:

my $dsn = 'DSN=SomeDataBase;UID=Foo;PWD=Bar';
my $odbc = new Win32::ODBC($dsn);
