PolarDB:Rename a partition

Each partition has their name, and PolarDB for PostgreSQL (Compatible with Oracle) supports the modification of partition names. This topic describes the syntax for renaming partitions and provides a sample statement.

ALTER TABLE <table_name> RENAME PARTITION <partition_name> TO <new_name>;
ALTER TABLE <table_name> RENAME SUBPARTITION <subpartition_name> TO <new_name>;

CREATE TABLE hash_partitions_sales (deptno NUMBER, deptname VARCHAR(32))
     PARTITION BY HASH(deptno)
       (PARTITION p1 , PARTITION p2 ,
        PARTITION p3 , PARTITION p4 , PARTITION p5);

ALTER TABLE hash_partitions_sales RENAME PARTITION p1 TO p1_new;
