clickhouse 建表知识点

去掉:
AUTO_INCREMENT=6967 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci COMMENT='用户表'
CHARACTER SET utf8 COLLATE utf8_general_ci
ON UPDATE
PRIMARY KEY
KEY

使用:
PARTITION BY (id) 根据id分区
ORDER BY (aa,bb) 排序

替换:
timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP => DateTime DEFAULT toDateTime(0)
InnoDB => MergeTree()
COMMENT='用户表' => COMMENT '用户表'
