Assuming that you have a table called `dvna_table` with a partition column called `partition_col`, here is an example of using the `ALTER TABLE` command to add a partition to the table:
```
ALTER TABLE dvna_table ADD PARTITION (partition_col='my_partition') LOCATION '/path/to/my_partition';
```
In this example, we use the `ALTER TABLE` command with the `ADD PARTITION` clause to add a partition to the `dvna_table` table. The `partition_col` parameter specifies the value of the partition column for the new partition, and the `LOCATION` parameter specifies the path to the partition data.
You can also use the `DROP PARTITION` clause to remove a partition from the table:
```
ALTER TABLE dvna_table DROP PARTITION (partition_col='my_partition');
```
In this example, we use the `ALTER TABLE` command with the `DROP PARTITION` clause to remove the partition with `partition_col` equal to `'my_partition'` from the `dvna_table` table.
You can also use the `RENAME PARTITION` clause to rename a partition:
```
ALTER TABLE dvna_table PARTITION (partition_col='old_partition') RENAME TO PARTITION (partition_col='new_partition');
```
In this example, we use the `ALTER TABLE` command with the `RENAME PARTITION` clause to rename the partition with `partition_col` equal to `'old_partition'` to `'new_partition'` in the `dvna_table` table.
