Question

I have tables like post,tag and post_tag .. Each post have some tags.. I want to get data like

post 1 with tagA, tagB, tagC
post 2 with tagB, tagD
.
..

post N with tagZ

how is the right sql statement?

post: id(int), title(varchar), text(varchar)
tag: id(int), title(varchar)
post_tag: id(int), post_id(int), tag_id(int) -> post_id foreign key on post table and tag_id foreign key on tag table.

for example i want fetch all posts with tags title.

1 “post1” “somepost bla bla” “tag1 title ” “tag2 title”
.
..

Try using group_concat to list all tags for a given post in a single field. See http://dev.mysql.com/doc/refman/5.0/en/group-by-functions.html
