Remove Duplicate title in database table mysql -

-

we have 2 tables called : "post" , "post_extra".

summary construction of "post" table's are: id, postdate, title, description.

and post_extra are: eid, news_id, rating, views

"id" filed in first table connected "news_id" second table.

there more 100,000 records on table, many of them duplicated. want keep 1 record , remove duplicate records on "post" table have same title, , remove connected record on "post_extra"

i ran query on phpmyadmin server crashed, , had restart it.

delete e post p1, post p2, post_extra e p1.postdate > p2.postdate , p1.title = p2.title , e.news_id = p1.id

how can this?

i think the id maximum in case of highest posteddate if can try code

delete post id in (select max(id) post group title)
