Some complex sql is not parsed correctly.

[liudonghua]

If I want to parse the following sql, the columns, columns_dict and so on are not correct.

CREATE TABLE `jeecg_order_main`  (
  `id` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '主键',
  `order_code` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '订单号',
  `ctype` varchar(500) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '订单类型',
  `order_date` datetime NULL DEFAULT NULL COMMENT '订单日期',
  `order_money` double(10, 3) NULL DEFAULT NULL COMMENT '订单金额',
  `content` varchar(500) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '订单备注',
  `create_by` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '创建人',
  `create_time` datetime NULL DEFAULT NULL COMMENT '创建时间',
  `update_by` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '修改人',
  `update_time` datetime NULL DEFAULT NULL COMMENT '修改时间',
  `bpm_status` varchar(3) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '流程状态',
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;
