DBI's internal objects are very weird. You are not supposed to be poking around in them anyway; there is nothing useful to be seen there, unless you are writing your own DBD:: module.

You got nothing because there is nothing to get; the object has nothing in it. Data::Dumper will show you the same thing, because that is the truth. A DBI statement handle object is a reference to an empty tied hash.

The hash is tied to an object which is implemented (probably) with another hash that actually contains real member data. You can see this by doing:

  x tied %$sth

in the debugger. But I don't really understand what you think you're going to accomplish by looking into the internals of the DBI object---it's unlikely that you will find anything there that you can 'debug'.

For most ordinary objects, you will not have to do this. The x command will do what you want.
