Drop Column in PL/SQL: ALTER TABLE Guide

In PL/SQL, to remove a field from a table, you can use the ALTER TABLE statement.

For example, if we have a table named “employees” with a field called “phone_number” that we want to delete, we can use the following statement:

ALTER TABLE employees DROP COLUMN phone_number;

After executing the above statement, the “phone_number” field in the “employees” table will be deleted. Please be aware that deleting a field is irreversible, so please proceed with caution.
