At a high level? It prepares your statement. At a low level?
Whatever DBD makes it do.

That depends. In Oracle, it will flag some errors. In Mysql,
I don't think it will even do that.

Fetch is an alias for fetchrow_arrayref. As I just discovered, this fact
is surprisingly very poorly documented in DBI.
"fetchrow_arrayref"
$ary_ref = $sth->fetchrow_arrayref;
$ary_ref = $sth->fetch; # alias
That appears to be it. There should be an entry that says:
"fetch"
An alias for fetchrow_arrayref.
