为了练习向 RAID 阵列中添加一个分区，我们可以作两种处理，这取决于您要模拟哪种场景。

To practice adding a partition back into our RAID array, we can do one of two things, depending on what kind of scenario you'd like to prepare or.

youdao

这样，如果您想添加一个分区表名为SALES的空分区，可以执行一个与下面类似的ALTER table语句。

Thus, if you wanted to add an empty partition to a partitioned table named SALES, you could do so by executing an ALTER table statement similar to this.

youdao

因此，如果您添加一个主分区，分区编号也有可能不会改变，但是如果您要添加一个逻辑分区，您所有的其他逻辑分区变化都会改变。

Thus, if you add a primary partition, it's possible that no partition Numbers will change; but if you add a logical partition, all your other logical partitions' Numbers may change.
