estimates,
I have a survey project for students in which there is a form_alumno table where students enter anonymously and fill out a form
then it is redirected to the survey, which consists of 21 questions and each question has 5 types of answers (1,2,3,4,5).
I have the following query that is to rescue the sum of the amount of each type of answer for each question and also a filter per course, year and semester:
SELECT p.id_pregunta, tr.tipo, COUNT(r.id_respuesta) as cantidad_respuestas
FROM preguntas p
LEFT JOIN tipo_respuesta tr on p.id_pregunta = tr.id_pregunta
LEFT JOIN respuesta r on tr.id_tipo = r.id_tipo
LEFT JOIN form_alumnos f on r.id_form_alumno_fk = f.id_form_alumno
WHERE f.cod_curso_alumno = '342139' AND f.anio = '2016' AND f.semestre = 'Primer'
GROUP BY p.id_pregunta, tr.tipo
What I need is that the tables give me the values or the table should look like this:
Id_respuesta tipo cantidad_respuesta
1 1 0
1 2 0
1 3 0
1 4 4
1 5 3
2 1 0
2 2 0
2 3 0
2 4 2
2 5 5
| | |
21 1 0
21 2 1
21 3 2
21 4 2
21 5 2
any guidance or help will be good in advance thanks
