mysql 日期维度序列生成

建表语句：

CREATE TABLE `shence`.`Untitled`  (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `date` datetime NULL DEFAULT NULL,
  `dayid` int(11) NULL DEFAULT NULL,
  `weekid` int(11) NULL DEFAULT NULL,
  `monthid` int(11) NULL DEFAULT NULL,
  `quartid` int(11) NULL DEFAULT NULL,
  `yearid` int(11) NULL DEFAULT NULL,
  `y` int(11) NULL DEFAULT NULL,
  `m` int(11) NULL DEFAULT NULL,
  `d` int(11) NULL DEFAULT NULL,
  `yearmon` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
  `weekstr` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
  `quar` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
  `weekday` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
  `monname` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
  `dayname` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 1
