I'm trying to do something like:

INSERT INTO stories 
   (vid, ip, body, timestamp) 
   (SELECT vid+1 FROM stories ORDER BY vid DESC LIMIT 1), 

but I'm having a problem figuring out how to nest a SELECT statement's returned data into an INSERT statement. I need to figure out how to get the highest existing vid and increment it by 1.

Any ideas?

use an explicit SELECT, not nested

INSERT INTO stories 
   (vid, ip, body, timestamp) 
   COALESCE(MAX(vid),0)+1,    --max always returns one row if no group by
FROM stories

that's a great solution! thank you. one more thing though - how do I return an integer 1 for vid value if table stories is empty? – donkapone Mar 20 '11 at 19:41
@Donkapone ~ That sounds like "I have two different business cases, I should test for one of them to be valid, and then execute one of two different paths depending on that test result" doesn't it? How would you solve it? – jcolebrand Mar 21 '11 at 19:34
