Dear folks,
On testing and documenting my implementation of the V2 DB API Spec,
I am bothered
by my (limited) understanding of what the spec says for the behavior of
Cursor.description .
Clearly when a query (or rather an SQL statement) does not produce a
result, .description should be None. However, not producing a result is
not the same as producing a table of
zero rows by one or more columns. (This is like the distinction between
the two comparisons
"" == False
and
"" is False
, the empty string has the same 'value' as False while remaining distinct.)
I do not know that this will ever make a difference to my users
but I am expected
to be precise in my implementation. Is it the general understanding
that .description
will return None whenever the result set has no rows?
Thank you all,
Arthur Protin
