In an Oracle database, you can use the following SQL statement to determine if a partition exists:

SELECT COUNT(*) 
FROM USER_TAB_PARTITIONS 
WHERE TABLE_NAME = '表名' AND PARTITION_NAME = '分区名';

Replace the table name with the name of the table to be queried, and replace the partition name with the name of the partition to be checked. If the returned result is greater than 0, it means the partition exists; if the result is 0, it means the partition does not exist.
