I want to get the details from the exam_question_list table, the expected results are the question, options from the question table according to the question_paper_list table 'q1-q5'
I try to get data, but it is not working;
SELECT *
FROM exam_question_list eq
LEFT JOIN exam_paper ex
ON eq.exam_paper_id = ex.exam_paper_id
LEFT JOIN job j
ON j.job_id = ex.job_id
LEFT JOIN job_catergory jc
ON jc.catergory_id = j.catergory_id
LEFT JOIN question q
ON q.question_id=eq.q1
this query give only question 1 only.I want to get All 5 questions.How to do it?
Your Query is wrong. Correct is
SELECT eq.*
FROM exam_question_list eq
LEFT JOIN exam_paper ex ON eq.exam_paper_id = ex.exam_paper_id
LEFT JOIN job j ON j.job_id = ex.job_id
LEFT JOIN job_catergory jc ON jc.catergory_id = j.catergory_id
LEFT JOIN question q ON q.question_id=eq.q1
you need the foreign keys in question because the relevant data is there and you start you select with question after all join you put where = id_whherever_you_want
the exam_question_list isn't associated with anything try make one relational data model this help you understand what u need change in database. delete exam_question_list and put all foreign keys on question
