MultipleChoice

Consider the Information Engineering diagram shown in the exhibit for a building

management company. Referential integrity must be maintained such that a building cannot be

deleted when it has residents. Building_ID, R_ID, Room_Count and Room_Num are integer

numbers, whereas Bldg_Name, Location and Res_Name are all represented by variable-length

strings with a maximum of 20 characters. Which SQL statement best implements the relations

shown in this diagram?

Options

ACREATE TABLE RESIDENT (
R_ID INTEGER NULL PRIMARY KEY,
Room_Num FLOAT,
Res_Name VARCHAR,
Building_ID INTEGER NULL,
FOREIGN KEY Building_ID REFERENCES BUILDING (Building_ID));

BCREATE TABLE BUILDING (
Building_ID INTEGER NOT NULL PRIMARY KEY,
Bldg_Name VARCHAR (20),
Location VARCHAR (20),
Room_Count INTEGER );
CREATE TABLE RESIDENT (
R_ID NOT NULL PRIMARY KEY,
Room_Num INTEGER,
Res_Name VARCHAR (20),
Building_ID INTEGER NOT NULL,
FOREIGN KEY Building_ID REFERENCES BUILDING (Building_ID)
ON DELETE NO CHECK
ON UPDATE CASCADE);

CCREATE TABLE RESIDENT (
R_ID INTEGER NOT NULL PRIMARY KEY,
Room_Num INTEGER,
Res_Name VARCHAR (20),
Building_ID INTEGER NOT NULL,
FOREIGN KEY Building_ID REFERENCES BUILDING (Building_ID));

DCREATE TABLE BUILDING (
Building_ID INTEGER NOT NULL PRIMARY KEY,
Bldg_Name VARCHAR (20),
Location VARCHAR (20),
Room_Count INTEGER );
CREATE TABLE RESIDENT (
R_ID NOT NULL PRIMARY KEY,
Room_Num INTEGER,
Res_Name VARCHAR (20),
Building_ID INTEGER NOT NULL,
FOREIGN KEY Building_ID REFERENCES RESIDENT (Building_ID)
ON DELETE NO CHECK);
