AFAIK, the '*' wildcard with LIKE is only valid in MS-Access "SQL"
(which gives an error with '%' ...duh...).

AFAIK it has to involves obtaining money or valuable services or
products from somebody, on promise of something of comparable value
in return, with deliberate intent to *not* keep that second half of
the deal. Since nothing of the sort is occurring in regard to
NewEco, you are committing libel every time you accuse me of

Dear Captain,
Sorry, but sarcasm does not really work, in cases like this....
I'm sorry, but where did I suggest I knew better than you? And I did
not refuse to give any information. Of course, I should have given the
FULL tabledef and expain in the first post, and by any next question I
have, I will. I did not think it would matter, after me trying to

One problem I have here is: Why should someone trust labor credits
on your site as opposed to other forms of currency, like Bernie
Madoff investments, Enron stock, promises of future benefits from
the Social Security system, S&H Green Stamps (anyone remember those?),
airline miles, or 1 contest entry in the Publisher's Clearinghouse

"now"? It has been for as long as I have coded SQL!

Ah yes, thanks. So '%' is wildcard now.

Because asterisk is not a wildcard in SQL.
Check the documentation for the LIKE clause.

Assuming there are records in the bills tables where
the id field is "AK2009H45", why doesn't the following
statement work?
select * from bills where id like "AK*45";

Well that is so kind of you.
I really don't get people like you. You come here to ask the experts
and when we ask you for the necessary information, you refuse to give
it, instead suggesting that you know better than us!
If you could read the explain output properly and knew how it all
worked, you wouldn't have needed to ask here in the first place.

It is saying it is not using a key - not that possible keys is null, as
you claimed in your previous statement. These are two entirely
different things.
MySQL will not use an index if it thinks the retrieval will return a
significant portion of the table. In a case like that, going to the
index and retrieving individual rows based on the index can be slower

Well, I can give you the whole query, and explain too:
mysql> describe item;
+------------+--------------+- -----+-----+---------+-------- --------+
+------------+--------------+- -----+-----+---------+-------- --------+
+------------+--------------+- -----+-----+---------+-------- --------+
mysql> explain select * from item where lat>50;

I don't believe you. If that really is all it says then there is
something seriously wrong.
