You can do regular expression
Select DISTINCT area from table like '$searchterms%';
In SQL, you can use the 'LIKE' keyword along with the '%' and '_'
wildcards.. '_' is one character, '%' is any number of chars.

Well, its not really a search that would be way easier. :-) What
I'm looking for is a query that will give me the complete list of
items that are distinct, minus the last number after the last hyphen.
animal-dog
animal-cat
animal-bird

Oh! I misunderstood..
This is tougher, you're selecting the entire set, so you won't have
anything after 'WHERE', but you're defining how the returned items are
formatted, this goes before table selection:
Select DISTINCT SUBSTRING_INDEX(`area`, '-', 2) from table;
I didn't test this, but
i'm a bit confused. if i'm getting you right heres my 2 cents:
first you do sql query using DISTINCT
when the result are returned to you, you can then run thru the result array
using preg_replace. heres an example:
$aVar= array(
'animal-dog-5',
'animal-dog-3',
i'm not sure if it is possible to use regular expression in a sql query.
can
anyone comment on this? thanks.
Mysql Postgres can. I'm sure others can too.

You can do regular expression matching in MySQL and I think a few other
servers too, but that's not the same as regular expression replacement
like you can do with PHP.. It just returns a boolean true/false
depending on whether or not the match works.
