I have a table db_race
--------------------------
| Name | Time | Map |
--------------------------
| Max | 240 | test1 |
| Alvin | 600 | test2 |
| Amanda | 234 | test1 |
| Angela | 50 | test1 |
| Angela | 2000 | test1 |
--------------------------
I now want to select some rows ordered by best Time on a map like the following
SELECT Name, min(Time) AS Time
FROM db_race
WHERE Map='test1'
GROUP BY Name
ORDER BY Time ASC
That works perfectly fine, but I want to have the best time of all records added to another column looking like the following. (will later work with that but thats not a part of the question)
----------------------------
| Name | Time | TopTime |
----------------------------
| Angela | 50 | 50 |
| Amanda | 234 | 50 |
| Max | 240 | 50 |
----------------------------
So far I tried the following but it only shows the best time, I want it for the whole selected table
SELECT *, min(Time) AS TopTime
FROM (SELECT Name, min(Time) AS Time
FROM db_race
WHERE Map='test1'
GROUP BY Name
ORDER BY Time ASC) a
I want to make sure I dont need to find the TopTime by using a subquery. The actual query will be very long and my goal is to not have it executed twice.
Something like this, perhaps?
SELECT
Name,
min(Time) as Time,
(SELECT min(Time) FROM db_race WHERE Map='test1') as TopTime
FROM db_race
WHERE Map='test1'
GROUP BY Name
ORDER BY Time
