To add partitions to a table, you can use the ALTER TABLE statement. Here is an example:

ALTER TABLE table_name PARTITION BY RANGE (column_name) (
  PARTITION p0 VALUES LESS THAN (value1),
  PARTITION p1 VALUES LESS THAN (value2),
  PARTITION p2 VALUES LESS THAN (value3)
);

In the example above, table_name is the name of the table to which partitions are being added, and column_name is the name of the column used for partitioning. Then, specify the type of partitioning using the PARTITION BY clause (in this case, RANGE). Next, list each partition with its corresponding value range in brackets.

Please note that adding partitions may result in data movement and reorganization, so be sure to backup the data in the table before performing this operation.
