QUERY Structure?

QUERY Structure?

Hi Dave,

If I understand the question right, sure it can be done:

SELECT id, LEFT(joketext, 20) FROM joke WHERE jokedate >= "2004-04-17"
AND joketext LIKE "%chicken%" ;

The joketext LIKE "%chicken%" condition won't be able to use any indexes
and could perform pretty slowly.  You might consider looking at
full-text indexes and search if you can use MyISAM tables:

Obviously, whether or not this is a good option depends on your actual
query and use cases.

Best regards,
