I fixed this line to read...
AND (bg.expire_time IS NULL OR bg.expire_time > {int:current_time})
and it works, and IMHO, is easier to read. 8)
afaik, this should work in MySQL too, as IS NULL is standard sql. COALESCE(INTEGER, BOOLEAN) doesn't make any sense to me. ???
fyi, this code is unchanged in 2.0.8 (yeah, I should have upgraded /before/ I posted).
I haven't actually tested my alternate sql in mysql but it SHOULD work as mysql supports the standard construct IS NULL.
I'm as stumped as you are as to why COALESCE() is used there. It's already been changed to IS NULL for 2.1 though.
