That is, DBI can return a value of 0E0 when an error occurs

Where in the DBI pod does it say when execute returns 0E0 there is an error. execute returns either, rows insert/updated/deleted, -1 (rows altered not known), 0E0 (no rows altered), undef (error)

I think you might be confusing this with the err method which can return '' (empty string) to indicate an informational state and 0 to indicate a warning.
