每小时累计和每天重置

Question

我有一系列数据需要每小时汇总数据

我可以使用具有显示值的excel数据透视表->运行总输入量

如何通过sql查询获得以上结果

CREATE TABLE `rawData`  (
  `ID` int(10) UNSIGNED NOT NULL AUTO_INCREMENT,
  `StartTime` datetime(0) NULL DEFAULT NULL,
  `Duration` decimal(10, 2) NULL DEFAULT NULL,
  PRIMARY KEY (`ID`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 23 CHARACTER SET = latin1 COLLATE = latin1_swedish_ci ROW_FORMAT = Dynamic;
