问题
I have a table which holds information on television programs and I want to order it by Seasons and then by episodes. Here's a basic view of what I have:
+---+--------+---------+
|id | Season | Episode |
+---+--------+---------+
| 1 | 1 | 1 |
+---+--------+---------+
| 1 | 1 | 2 |
+---+--------+---------+
| 1 | 2 | 1 |
+---+--------+---------+
| 1 | 2 | 3 |
+---+--------+---------+
So I select what I need and order by Season. But there's going to be a lot between seasons so I need to sort episodes too, but without it affecting seasons.
回答1:
Do you mean:
SELECT id, Season, Episode
FROM table
ORDER BY Season ASC, Epsisode ASC
Sorting by multiple columns is as simple as it gets.
回答2:
We know what you mean :) In your order by you should have
ORDER BY Season, Episode
It will sort by Season and then on Episode within Season
