Define the term referential integrity constraint. Give an example of a referential integrity constraint for the tables you created for question 1.8.
Write SQL statements to create at the two tables for the database. The tables must have at least three relevant columns with appropriate types, a primary key and at least one table should have a foreign key and the related foreign key constraints.
CREATE TABLE students (
Student_id int NOT NULL PRIMARY KEY,
Stud_firstname VARCHAR(30) NOT NULL,
Stud_lastname VARCHAR(30) NOT NULL,
Stud_email VARCHAR(80) NOT NULL UNIQUE
advisor_id int,
);
create table advisor (
advisor_id int not null primary key,
stud_id int,
adv_firstname varchar(30),
adv_lastname varchar(30),
foreign key(student_id) references students(student_id)
);
[keep getting error, need help correcting]
Not all versions of this database include referential integrity constraints for all foreign keys. Use whatever commands are available for the RDBMS you are using, investigate if any referential integrity constraints are missing. Write any missing constraints and, if possible, add them to the associated table definitions.

You need to create a constraint in the ACTIVE_DRIVERS table, called DuplicateCheck, to ensure the first name, last name, and the driving license ID are unique.

All keys can store between 6 to 10 characters. All the columns must have values (cannot be empty). Add on charges is set to 0.00 by default. Enforce entity and referential integrities. b) Diplay the therapists’ particulars (include TheraName, TheraContact) as first two columns, then calculate the Total_Count_Of_Appointment for each therapist within the year 2020 as third columns. Lastly, arrange the outcome to show the list by the higher popularity of therapists first.arrow_forward
- Write SQL code for the following design schema of three tables. The tables should have the following properties: sales table has a primary key on SalesNumber and it is set to AUTO-INCREMENT.products table has a primary key on number and it is set to AUTO-INCREMENT, they is an unique index on prodidsalesdetails table has a primary key on number and it is set to AUTO-INCREMENT, they is an index on prodid. They is a one-to-many relationship between the salesdetails.SalesNumber andsales.SalesNumber fields. There is a one-to-many relationship between the products.prodid and salesdetails.prodid fields. There is to be a delete constraint on the product.prodid field a record in the product table should not be allowed to be deleted if they exist a matching prodid in the salesdetails table. Primary and foreign keys should be implemented in the appropriate tables. Referential Integrity should be enforce at the database level, where appropriate for example, if a sales record is deleted all…arrow_forwardThe Car Maintenance team also wants to store the actual maintenance operations in the database. The team wants to start with a table to store CAR_ID (CHAR(5)), MAINTENANCE_TYPE_ID (CHAR(5)) and MAINTENANCE_DUE (DATE) date for the operation. Create a new table named MAINTENANCES. The PRIMARY_KEY should be the combination of the three fields. The CAR_ID and MAINTENACNE_TYPE_ID should be foreign keys to their original tables. Cascade update and cascade delete the foreign keys.arrow_forwardUsing the Henry Books database,Henry Books no longer carries books written by Barbara Owen. Delete this author from the authors table.

- Write CREATE TABLE statements to implement the following design. Include foreign key constraints. Define the individualID, and GroupID as identity columns. Decide which columns should allow null values, if any. Define Dues column with a default of zero and check constraints to allow only positive values.arrow_forwardAssume you have a vehicle table with a surrogate key vehicle_id column and VIN (Vehicle Identification Number) column and some other columns. You want to designate a unique index on the vehicle_id and VIN columns because together they filter on the joining column with the highest cardinality (or degree of uniqueness). Write the syntax to add a unique index on the vehicle_id and VIN columns triggered by joins on the surrogate key column?arrow_forwardTask 2: The Driver Relationship team wants to ensure that the all driving license IDs in the active drivers table have the length of 7. Alter the ACTIVE_DRIVERS table created in Chapter 8, Activity 1 to check the length of the DRIVER_DRIVING_LICENSE_ID. Add a CHECK to the ACTIVE_DRIVERS table to enforce a driver license length of 7.
