I have two tables:

1.ChapterQuest columns(Id(int),QuestionId(int),Question(varchar(max),OptionA(varchar(100)),
OptionB(varchar(100)),OptionC(varchar(100)),Answer(varchar(10),Ismultiple(bit))

2.ChapterQuestAnswer columns(Id(int),ChapterQuestionID(int),OptionSelect(varchar(10))

Data In ChapterQuest is:

Id  QuestionId  Question  OptionA  OptionB  OptionC  Answer  Ismultiple

Hi ,

This will give you your desired result if values inserted in your answer field and optionselect without any space in between the answer and sperated by comma.

For Right answer

select * from ChapterQuestAnswer t join ChapterQuest q on t.questionid= q.chapterquestionid and t.answer=q.optionselect

For Wrong Answer
select * from ChapterQuestAnswer t join ChapterQuest q on t.questionid= q.chapterquestionid and t.answer <> q.optionselect

or you can view questionid( not attempted) not there in your chapteranswer like this

select * form ChapterQuest where QuestionId not in ( select distinct ChapterQuestionId from ChapterQuestAnswer )

Regards,
Mubin
