SELECT Count(*) FROM Work WHERE (UserID='user1' AND MAX(Finished)=0)
Work:-
+---+-------+--------+---------+----------+| ID | JobID | UserID | Finished | Comment |
+---+-------+--------+---------+----------+| 1 | 1 | user1 | 0 | ... || 2 | 1
| user1 | 1 | ... || 3 | 2 | user2 | 0 | ... || 4 |
3 | user1 | 0 | ... || 5 | 2 | user2 | 0 | ... ||
6 | 2 | user1 | 1 | ... || 7 | 3 | user1 | 0 | ...
|
+---+-------+--------+---------+----------+
All I want it to do is return the number of unfinished jobs for a specific
user.
In this example it would return 1 because job number 3 is not finished and
user1 was the last person working on it.
but I keep getting MySQL error #1111 - Invalid use of group function
