4、LIST分区 LIST分区没有类似如“VALUESLESS THAN MAXVALUE”这样的包含其他值在内的定义。将要匹配的任何值都必须在值列表中找到。 5、Linear线性 分区策略KEY和HASH都支持使用线性LINEAR的算法,也就是分区的编号是通过2的幂(powers-of-two)算法得到,而不是通过模数算法。 垂直分表、水平分表 垂直分表 1.减少...

But, though you didn't mention it in your query spec, you presumably want not the max bmi_id in the table, but rather the latest and previous bmi_weight values for a particular member, or a set of them, so you'll need to partition the lag window by member_id. Absent a script as...
After the INSERT..SELECT statement, the AUTO_INCREMENT of the table in which I'm inserting values from another table is equal to nearest (but bigger then inserted count) power of two. For example when I'm inserting 2 rows it equals 4, for 4 rows - 8, for 10 - 16 and so on. ...
