Why I'm doing:
When partitions p4 and p5 in the base table t1 change, cascading will cause the refresh of p1 and p5 in the materialized view mv1. However, p1 includes two partitions, 2020-07-01 and 2020-07-02, and the partition 2020-07-02 does not only come from the partition p4. Therefore, other partitions it depends on must also be taken into account.
Since p1 contains two partitions, 2020-07-01 and 2020-07-02, and the partition 2020-07-02 is not solely derived from the p4 partition, other partitions it depends on must also be considered when cascading the refresh. Therefore, during the cascaded refresh, it is necessary to include partitions p1, p2, and p3 that have not changed:
