Question

First off, the version of MYSQL I’m using is 5.1.66-community-log.

Now that we got that out of the way, I’m retrieving the following error when trying to create the below view:

You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near ‘all select RRA.id, RRA.reply_id as replyID, RRA.user_id,
RRA.vote_up, RRA.rank’ at line 4

and the view:

$sql = "Create or replace view userRank as 
select PRA.id, PRA.post_id as postID, PRA.user_id, PRA.vote_up, PRA.rank_date 
from post_rank_activity PRA
union all 
select RRA.id, RRA.reply_id as replyID, RRA.user_id, RRA.vote_up, RRA.rank_date 
from reply_rank_activity RRA";

I’ve checked a few sites and this seems to be the correct syntax – or has something changed over time?

Answer 1

Parentheses may helps, try :

Create or replace view userRank as 
(select PRA.id, PRA.post_id as postID, PRA.user_id, PRA.vote_up, PRA.rank_date 
from post_rank_activity PRA)
union all 
(select RRA.id, RRA.reply_id as replyID, RRA.user_id, RRA.vote_up, RRA.rank_date 
from reply_rank_activity RRA)
