创建分区表：首先，使用CREATE TABLE语句创建表，并在表的定义中加入PARTITION BY子句，指定分区键和分区方式。例如：CREATE TABLE sales

(

sales_id NUMBER,

sales_date DATE,

amount NUMBER

)

PARTITION BY RANGE (sales_date)

(

PARTITION sales_q1 VALUES LESS THAN (TO_DATE(‘01-APR-2022’,‘DD-MON-YYYY’)),

PARTITION sales_q2 VALUES LESS THAN (TO_DATE(‘01-JUL-2022’,‘DD-MON-YYYY’)),

PARTITION sales_q3 VALUES LESS THAN (TO_DATE(‘01-OCT-2022’,‘DD-MON-YYYY’)),

PARTITION sales_q4 VALUES LESS THAN (TO_DATE(‘01-JAN-2023’,‘DD-MON-YYYY’))

);

添加分区：可以使用ALTER TABLE语句为现有的分区表添加新的分区。例如：ALTER TABLE sales ADD PARTITION sales_q5 VALUES LESS THAN (TO_DATE(‘01-JAN-2024’,‘DD-MON-YYYY’));

删除分区：通过ALTER TABLE语句删除分区。例如：ALTER TABLE sales DROP PARTITION sales_q5;

合并分区：可以使用ALTER TABLE语句合并相邻的分区。例如：ALTER TABLE sales MERGE PARTITIONS sales_q1, sales_q2 INTO sales_q1_q2;

拆分分区：可以使用ALTER TABLE语句将一个分区拆分成多个分区。例如：ALTER TABLE sales SPLIT PARTITION sales_q1 INTO (PARTITION sales_q1_a VALUES LESS THAN (TO_DATE(‘01-MAY-2022’,‘DD-MON-YYYY’)), PARTITION sales_q1_b VALUES LESS THAN (TO_DATE(‘01-JUL-2022’,‘DD-MON-YYYY’)));
