我有一个具有以下结构和示例数据的表:
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的每小时总计TOTAL_AMOUNT。我尝试了以下查询,但我不知道它是否正确。
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;
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;
