To add a new partition in the original Oracle table, follow these steps:

  1. Firstly, confirm that the table has been enabled with partitioning. You can use the following statement to check if the table has been enabled with partitioning:
  2. Retrieve the table name and partition status from all tables where the table name is equal to ‘your_table_name’.
  3. If the table is not partitioned, you can use the ALTER TABLE statement to modify it into a partitioned table. For example, you can modify the table “your_table_name” to be partitioned by date.
  4. Modify the table “your_table_name” to partition by range using the column “your_partition_column” with an interval of “your_partition_interval”. Define partitions based on specific values such as “your_partition_value1” for “p1” and “your_partition_value2” for “p2”.
  5. Your_partition_column is the name of the column used for partitioning, your_partition_interval is the size of the partition interval, and your_partition_value1, your_partition_value2, and so on are the range values of the partition.
  6. If partitioning is already enabled on the table, you can use the ALTER TABLE statement to add a new partition. For example, adding a partition named new_partition.
  7. Add a new partition to your table, with values less than the specified partition value.
  8. your_partition_value represents the range value of the new partition.
  9. After adding a new partition, you can use the INSERT statement to insert data into the new partition. For example:
  10. Add data to your table with specific columns by specifying the partition column and its corresponding value, along with values for other columns.
  11. Here, your_partition_column is the name of the partition column, your_partition_value is the range value for the new partition, and other_columns and other_values are the names of other columns and their corresponding values.

Before performing partitioning operations, make sure to properly back up the table and proceed with caution in a production environment. Partitioning operations may have an impact on performance and storage requirements, so evaluation and optimization should be done based on specific circumstances.
