mysql sum GROUP BY
ID NAME TYPE TOTAL
1 user1 1 5
2 user1 2 10
3 user2 1 5
4 user2 1 10
5 user3 3 20
6 user2 3 10
.........
NAME 和 TYPE
的总分组我想要这个结果
NAME TYPE1 TYPE2 TYPE3 TYPE4 TYPE5
user1 5 10 0 0 0
user2 15 0 10 0 0
user3 0 0 20 0 0
---------------------------------------------
Total 20 10 30 0 0
php和mysql((max type 9)) 感谢!!!!

答案 0 :(得分:1)
这应该可以解决问题:
SELECT
tt.`name` AS NAME,
SUM(CASE WHEN tt.type = 1 THEN tt.total ELSE 0 END) AS TYPE1,
SUM(CASE WHEN tt.type = 2 THEN tt.total ELSE 0 END) AS TYPE2,
SUM(CASE WHEN tt.type = 3 THEN tt.total ELSE 0 END) AS TYPE3,
SUM(CASE WHEN tt.type = 4 THEN tt.total ELSE 0 END) AS TYPE4,
SUM(CASE WHEN tt.type = 5 THEN tt.total ELSE 0 END) AS TYPE5,
SUM(CASE WHEN tt.type = 6 THEN tt.total ELSE 0 END) AS TYPE6,
SUM(CASE WHEN tt.type = 7 THEN tt.total ELSE 0 END) AS TYPE7,
SUM(CASE WHEN tt.type = 8 THEN tt.total ELSE 0 END) AS TYPE8,
SUM(CASE WHEN tt.type = 9 THEN tt.total ELSE 0 END) AS TYPE9
FROM
test_table AS tt
GROUP BY
tt.`name`
