我有一个具有以下结构和示例数据的表:

I have a table with the following structure and sample data:

STORE_ID | INS_TIME | TOTAL_AMOUNT 2 07:46:01 20 3 19:20:05 100 4 12:40:21 87 5 09:05:08 5 6 11:30:00 12 6 14:22:07 100

我需要获取每个 STORE_ID 的每小时总金额 TOTAL_AMOUNT.我尝试了以下查询，但我不知道它是否正确.

I need to get the hourly sum of TOTAL_AMOUNT for each STORE_ID. I tried the following query but i don't know if it's correct.

SELECT STORE_ID, SUM(TOTAL_AMOUNT) , HOUR(INS_TIME) as HOUR FROM VENDAS201302 WHERE MINUTE(INS_TIME) <=59 GROUP BY HOUR,STORE_ID ORDER BY INS_TIME;

推荐答案

SELECT STORE_ID, HOUR(INS_TIME) as HOUR_OF_TIME, SUM(TOTAL_AMOUNT) as AMOUNT_SUM FROM VENDAS201302 GROUP BY STORE_ID, HOUR_OF_TIME ORDER BY INS_TIME;
