#67: Add methods for returning scalar values
--------------------------------+-----------------
Reporter: cito | Owner:
Type: enhancement | Status: new
Priority: minor | Milestone: 5.1
Component: Classic and DB API | Version: 4.1
Keywords: scalar |
--------------------------------+-----------------
Often you have queries that are intended to return only a single row of
values, a single column of values, or just a single value.
In these cases, it would be useful to have methods that return the data
only as a single sequence (not a sequence of sequences), or a single
value.
The DB API 2 already has the fetchone() method that can be used to get a
single row. The classic interface does not have such a method. Both do not
have a method for returning a single column or single scalar value.
Maybe a `fetchscalar()` method for the DB API 2 and a `getscalar()` method
for the classic interface would be useful.
See also #48 ("Add methods returning interator of rows to the classic
module") in this context.
