comparing two tables

[xxreenaxx1]

I am writing a program which checks the results for a student. If the results are same as the ones inside the table, then correct message is printed. If the results are not the same then the right answer should be printed as well as wrong message and the answer the user selected. I am using checkbox to let the user choose the answers and this is saved on to the database.

 

I need to retrieve this and compare this with the original table.

 

my tables are

Answer: ,Ans_ID,Ans_Answer1, Ans_Answer2, Ans_Answer3, Ans_Answer4,Que_ID

Question:Que_ID, Que_Answer1, Que_Answer2, Que_Answer3, Que_Answer4

 

Answer table is what the user enters and the question table is the one with the correct answer.

 

SELECT Ans_ID, IF(answer.Ans_Answer1 = question.Que_Answer1 AND answer.Ans_Answer1 = question.Que_Answer1 AND answer.Ans_Answer1 = question.Que_Answer1  AND answer.Ans_Answer1 = question.Que_Answer1, "Correct","Wrong") AS result FROM answer LEFT JOIN question ON answer_id = question_id
