recursive query, store path MySQL


I have a table with two columns

'parentid' 'productref'

the 'parentid' column path always starts at '0' and follows a tree structure, so parentid can have a path '0' '3' '67' '4567'

currently only the final parentid is stored.
I would like a query that would find the path and output something like:

'productref' 'parentpath'

1234            0|3|67|4567

Any suggestions?

while you can do this in MS SQL and oracle easily, not so easy to crack in MySQL.

you should read up this page which discusses the options you have, starting with how to store the data:
