通过PersonID获取每个Person的SUM

Question

我在表格中有以下列：

SCORE_ID 
SCORE_PERSON_ID 
SCORE_VOTE

SCORE_PERSON_ID是一个变量。我需要根据SCORE_PERSON_ID对SCORE_VOTE求和。

你能建议一个好方法吗？

Answer 1

您需要GROUP BY和汇总功能，例如count或sum

SELECT SCORE_PERSON_ID, sum(SCORE_VOTE) as score
FROM table 
GROUP BY `SCORE_PERSON_ID`

Answer 2

我认为这是你要求的：

SELECT SUM(SCORE_VOTE)
  FROM <your_table_name>
 WHERE SCORE_PERSON_ID = <some value>

或者这个：

SELECT SUM(SCORE_VOTE)
  FROM <your_table_name>
 GROUP BY SCORE_PERSON_ID

希望有所帮助。祝你好运。

Answer 3

SELECT SUM(SCORE_VOTE)
FROM SCORES
GROUP BY SCORE_PERSON_ID

Answer 4

怎么样

select sum(SCORE_VOTE) as score  from TABLE group by SCORE_PERSON_ID 

这是为每个人总结的

select sum(SCORE_VOTE)  as score  from TABLE where SCORE_PERSON_ID = 1
