Oracle SQL-ALTER TABLE Error

Question

I've been looking over the following SQL code for awhile and just can't seem to find the problem. I'm relatively new to SQL, so I'm sure it's just something I'm overlooking. The error message I get is: ORA-01735: Invalid ALTER TABLE option.

Code:

ALTER TABLE PATIENT
(
ADD CONSTRAINT PProfileForeignKey
    FOREIGN KEY (pProfileID) REFERENCES PATIENT_PROFILE(Profile_ID),
ADD CONSTRAINT InsForeignKey
    FOREIGN KEY (pInsID) REFERENCES INSURANCE(Insurance_ID)
        ON DELETE SET NULL
);

I have triple checked to make sure the foreign key column names and the referenced column names are correct.

Answer 1

seems The parentheses are in wrong place

ALTER TABLE PATIENT
 ADD (CONSTRAINT PProfileForeignKey
    FOREIGN KEY (pProfileID) REFERENCES PATIENT_PROFILE(Profile_ID),
    CONSTRAINT InsForeignKey
    FOREIGN KEY (pInsID) REFERENCES INSURANCE(Insurance_ID)
        ON DELETE SET NULL);
