Use the ALTER SESSION statement to specify or modify any of the conditions or parameters that affect your connection to the database.

How do you alter foreign keys in oracle?
To alter foreign keys in Oracle, you can use the ALTER TABLE statement. To modify an existing foreign key constraint, you typically need to drop the existing constraint first using ALTER TABLE table_name DROP CONSTRAINT constraint_name, then add a new foreign key constraint with the desired modifications using ALTER TABLE table_name ADD CONSTRAINT constraint_name FOREIGN KEY (column_name) REFERENCES other_table (other_column). If you only need to disable or enable the constraint without altering it, you can use ALTER TABLE table_name DISABLE CONSTRAINT constraint_name or ENABLE CONSTRAINT.
