in Oracle To remove the primary key of a table, you can follow these steps:

Firstly, use the following syntax to view the primary key name of the table:
Choose the constraint name from the user_constraints table where the table name is ‘your_table_name’ and the constraint type is ‘P’.
Next, remove the primary key from the table using the following syntax:
Modify the table by removing the primary key constraint named primary_key_name.

In the above syntax, your_table_name is the name of the table from which you want to delete the primary key, and primary_key_name is the name of the primary key you want to delete. By following these steps, you can successfully delete the primary key of the table.
