Hi guys, Ive got two tables, one a listings and another representing a list of tags for the listing table.

In the listings table the tag ids are stored in a field called tags as 1-2-3- this has worked out very well for me regular expressions and joins to seperate and display the data, BUT... I now need to pull the titles of those tags into a single row. See below.

listings table
id    tags
1     1-2-3-
2     4-5-6-


tags table
id    title
1     pig
2     dog
3     cat
4     mouse
5     elephant
6     duck

And what I need to produce out of the listings table is:

id     tags
2      mouse, elephant, duck

any suggestions?
