Creating a crosstab query in MySQL - mysql

Question

I have a MySQL table that tracks certain totals by both hour of the day and various locations. I am trying to create a query that will total not only each column, but also each row. The query I have so far totals each column, but I can't figure out how to get a total for each row as well.
This is my query:
SELECT * FROM
(SELECT IFNULL(hour,"Total") as hour, SUM(location1), SUM(location2), SUM(location3), SUM(location4), SUM(location), FROM counts WHERE ay = 'AY1617' GROUP BY hour WITH ROLLUP) as crossdata
ORDER BY FIELD (hour,'8:00am','9:00am','10:00am','11:00am','12:00pm','1:00pm','2:00pm','3:00pm','4:00pm','5:00pm','6:00pm','7:00pm','8:00pm','9:00pm','10:00pm','11:00pm')
This is ultimately what I want the output to look like:
hour location1 location2 location3 location4 totals
8am 4 3 2 1 10
9am 1 2 2 1 6
10am 2 3 2 3 10
totals 7 8 6 5 26
How can I achieve this?

For what it's worth, this is not a crosstab query. You aren't pivoting rows to columns.
I tried this query and got the result you want:
SELECT IFNULL(hour, 'Total') AS hour,
SUM(location1) AS location1,
SUM(location2) AS location2,
SUM(location3) AS location3,
SUM(location4) AS location4,
SUM(location1)+SUM(location2)+SUM(location3)+SUM(location4) AS totals
FROM counts
WHERE ay = 'AY1617'
GROUP BY hour WITH ROLLUP;
You should really use the TIME data type instead of strings for the hour. Then it just sorts correctly.
+----------+-----------+-----------+-----------+-----------+--------+
| hourt | location1 | location2 | location3 | location4 | totals |
+----------+-----------+-----------+-----------+-----------+--------+
| 08:00:00 | 4 | 3 | 2 | 1 | 10 |
| 09:00:00 | 1 | 2 | 2 | 1 | 6 |
| 10:00:00 | 2 | 3 | 2 | 3 | 10 |
| Total | 7 | 8 | 6 | 5 | 26 |
+----------+-----------+-----------+-----------+-----------+--------+
