Interval Partition是Range分区的一个扩展。 举例说明: CREATE TABLE t1 (order_date DATE, ...) PARTITON BY RANGE (order_date) INTERVAL 1 MONTH (PARTITION p_first VALUES LESS THAN ( '2021-01-01'); 分区键和主键解耦(UNIQUE CHECK IGNORE) MySQL要求主键、唯一键必须包含分区键,增加选项忽略该检查,可...
MySQL可以通过使用分区表的方式按日期进行分区。下面是一种按日期分区表的方法: 创建一个新表,包含要进行分区的列和其他需要的列。 CREATE TABLE my_table ( id INT, date_column DATE, other_column VARCHAR(255), ... ) PARTITION BY RANGE(TO_DAYS(date_column)); 复制代码 创建分区 ALTER TABLE my_...

下面,开始聊聊本次引入partition遇到的一些坑吧! 各种坑 一、确认你是用的MySQL支持分区 SHOW PLUGINS -- 查看 partition 的 status = ACTIVE 二、由于需要按照日期创建分期,使用字段 created_at 按照指定日期创建分区: 创建分区命令: -- 添加分区 ALTER TABLE partition_test PARTITION BY RANGE(TO_DAYS(created_...
