  • 使用 ALTER TABLE 命令来把一个分区分为两个分区

     

    ALTER TABLE p_store_sales SPLIT PARTITION FOR ('2016-01-01')

    AT ('2016-01-16')

    INTO (PARTITION part_001, PARTITION part_002);

    如果您的分区表中包含默认分区,您必须通过分裂默认分区的方式来增加新的分区。在使用 INTO 子句时,需要将默认分区做为第二个分区名称。例如:

     

    ALTER TABLE p_store_sales SPLIT DEFAULT PARTITION

    START ('2016-01-01') INCLUSIVE

    END ('20016-02-01') EXCLUSIVE

    INTO (PARTITION new_part, default partition);
