There is always the Executed flag in DBI:

Executed (boolean)

The Executed attribute is true if the handle object has been "executed". Currently only the $dbh do() method and the $sth execute(), execute_array(), and execute_for_fetch() methods set the Executed attribute.

When it's set on a handle it is also set on the parent handle at the same time. So calling execute() on a $sth also sets the Executed attribute on the parent $dbh.

The Executed attribute for a database handle is cleared by the commit() and rollback() methods. The Executed attribute of a statement handle is not cleared by the DBI under any circumstances and so acts as a permanent record of whether the statement handle was ever used.

The Executed attribute was added in DBI 1.41.

Update: I must admit to some curiousity, as to why you might need this functionality. I generally rely on the AUTOCOMMIT flag, and rollback as necessary, in the rare occasions when I have multi-stage transactions that go bad. Can you comment on your use case?
