Hi Jeff,
'2000-12-14' is only 10 chars long.
You're asking for an 11-char long substring to match a 10-char ... not
going to happen!
You can see this better if you do something like this ...
select '@' || substr(datefoo,1,11) || '@' from table;
... and you'll get results like:
@2000-12-14 @
So, you could modify your query to do:
select foo from table where substr(datefoo, 1, 10) = '2000-12-14';
Alternatively, what's wrong with this approach?
select foo from table where date(datefoo) = '2000-12-14';
I think that might execute a little faster.
Hope this helps
