MySQL where 搜索问题

Question

I cannot seem to search when I add WHERE statement below. But it works without it....

Is there something wrong?

Below is my code: Thank you.

SELECT DISTINCT (
                    `name`
                    ), users.id, `email`, `state_id`,
                    MAX(`total_time_driven_at_this_trip`) AS trip
                    FROM `users`
                    LEFT JOIN trip_vics ON users.id = trip_vics.user_id
                    GROUP BY `user_id`
                    WHERE name LIKE '%dan%' 

Answer 1

You need to place your where right before group by

Answer 2

The WHERE keyword can't be used with aggregate functions. Use HAVING instead http://www.w3schools.com/sql/sql_having.asp

Put WHERE before the group by if you want to apply the filter before MAX is calculated.

Answer 3

having goes with group by .

having name like '%dan%'

Or if you are actually trying to have a where clause independent of the having clause, it should go between the join and the group by statement.
