Task 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.
Test Query:
SELECT DISTINCT(constraint_name)
FROM information_schema.check_constraints
WHERE constraint_schema = 'InstantRide'
AND constraint_name = 'ACTIVE_DRIVERS_chk_1'
Expected Results
CONSTRAINT_NAME
ACTIVE_DRIVERS_chk_1
Could you do typing the query here please?
Here are the previous steps that have been done before reaching the question below:
step 1:
Task 1: Q1.Please write a query statement from emp table to display deptno 10’s empno, ename, sal, and a new_sal which is increase by 15% from the original sal (round the new_sal value to a whole number). Label the column headings to EMPNO, ENAME, SAL, and NEW_SAL.
Answer:
SELECT empno, ename, sal, new_salFROM deptnoWHERE new_sal = orginal_sal * 1.15
ALTER TABLE deptnoRENAME COLUMN empno to EMPNO;
ALTER TABLE deptnoRENAME COLUMN ename TO ENAME;
ALTER TABLE deptnoRENAME COLUMN sal TO SAL;
ALTER TABLE deptnoRENAME new_sal empno TO NEW_SAL;
step2:
Task 2: Please write a query statement from emp table to display deptno 30’s empno, ename, sal, comm, and total_income which is a new column of the amount of sal + comm. Label the column heading to EMPNO, ENAME, SAL, COMM, TOTAL_INCOME. The result should be like below:
Answer:
ALTER TABLE deptnoADD total_income INT NOT NULL
SELECT empno, ename,…
