I believe that some time in the future mysql will support oracle style
connect by prior syntax but it's not implemented yet.

I am looking to do a query on a self join table that returns the parent
records.
Obviously there are ways to do this, but just wondered if there are any
functions in MySQL that make this easier, or specific functions
available to stored procedures. I have read the manual and couldn't find
any

Hi,
in oracle we have connect by prior for hierachical data traversal.
in mysql, you can use group_concat like this :
mysql> select parentid, group_concat(id) from ids
-> group by parentid;
+--+--+
| parentid | group_concat(id) |
+--+--+

Well, if you have everything setup right.. this is easy to do in SQL.
Lets say you have your root table:
create table root(
id integer unsigned not null auto_increment,
description varchar(50),

and your sub categories:
