#Inserts begin Here
INSERT INTO new_schema2.Employee 
       (EID, Fname, Lname, AddressID, PayLevel, Jobtitle, DateofEmployment) 
       VALUES 
   (    0,'Andrew','Wiggins','7', 10000.00,'Stock Boy','08/11/12' );

 INSERT INTO new_schema2.Employee

#Delete statements begin here
DELETE FROM new_schema2.employee
WHERE EID = 0 AND Fname='Andrew' AND Lname='Wiggins' AND AddressID='7' AND  DateofEmployment='11/12/08'  AND PayLevel='10000.00'AND  Jobtitle = 'Stock Boy'; 

Answer 1

The reason its not deleting because its failing on date condition.

You have field as

`DateofEmployment` DATE NOT NULL

When you insert 08/11/12 in MySQL it will become as 2008-11-12

So the delete command should be as

DELETE FROM Employee
WHERE EID = 0 
AND Fname='Andrew' 
AND Lname='Wiggins' 
AND AddressID='7' 
AND  DateofEmployment='2008-11-12'  
AND PayLevel='10000.00'
AND Jobtitle = 'Stock Boy';

Check with

SELECT DateofEmployment FROM Employee

And see how data is shown, you will get the answer by yourself.

Answer 2

you dont need to specify all columns in your delete

Use just this

   DELETE FROM new_schema2.employee
   WHERE EID = 0
