写一个PL/SQL的存储过程:新增天分区

好的,这是一个PL/SQL的存储过程,用于新增天分区:
CREATE OR REPLACE PROCEDURE add_daily_partition (
p_table_name IN VARCHAR2,
p_partition_date IN DATE
) AS
v_partition_name VARCHAR2(30);
BEGIN
-- Generate the partition name using the partition date
v_partition_name := 'P_' || TO_CHAR(p_partition_date, 'YYYYMMDD');
-- Check if the partition already exists
IF NOT DBMS_PARTITION_MANAGER.EXISTS_PARTITION (
p_table_name,
v_partition_name
) THEN
-- Create the partition using the partition name and date
DBMS_PARTITION_MANAGER.CREATE_RANGE_PARTITION (
table_name => p_table_name,
partition_name => v_partition_name,
partition_value => p_partition_date
);
DBMS_OUTPUT.PUT_LINE ('Partition ' || v_partition_name || ' created successfully.');
ELSE
DBMS_OUTPUT.PUT_LINE ('Partition ' || v_partition_name || ' already exists.');
END IF;
COMMIT;
EXCEPTION
WHEN OTHERS THEN
ROLLBACK;
DBMS_OUTPUT.PUT_LINE ('An error occurred: ' || SQLERRM);
END add_daily_partition;
其中,p_table_name是表名,p_partition_date是要新增的分区日期。该存储过程会自动生成分区名称,并检查该分区是否已存在。如果不存在,则创建新的分区,如果已存在,则不会创建任何新分区。
