getting related subjects for student in mysql - mysql

Question

I am trying to get subjects, which student has been enrolled using MySQL.
Student Table :
subjects table :
student enrolled subjects :
My query :
select *,(select subject_id from stu_subjects ss where ss.student_id =
s.student_id ) as subject_id
from student s
when executing above query I'm getting below error :
So i modified my query as below (added limit 1) :
select *,(select subject_id from stu_subjects ss where ss.student_id =
s.student_id limit 1) as subject_id
from student s
Final Output :
If you see the output I'm getting only one subject mapped to a student. But I need every subject which student has enrolled. So how can I achieve it?
What I'm trying to achieve is :

Answer 1

Althought Jagrut Sharma's answer is correct, this version specifies the separator of the subjects' ids, and uses an explicit JOIN rather than the implicit one.
Edit: It appears that , is the default separator, so you can omit it from GROUP_CONCAT. I'll leave it there in my query just so you know how to change it, if needed.
SELECT st.student_id, st.student_name
GROUP_CONCAT(sb.subject_id SEPARATOR ',')
FROM stu_subjects sb JOIN student st ON sb.student_id = st.student_id
GROUP BY st.student_id;

Answer 2

Use this query:
select a.student_id, b.student_name, group_concat(a.subject_id) as student_enrollment
from stu_subjects a, student b
where a.student_id = b.student_id
group by a.student_id, b.student_name;
Illustration:
-- table: student
> select * from student;
+------------+--------------+
| student_id | student_name |
+------------+--------------+
| 1 | Student-1 |
| 2 | Student-2 |
+------------+--------------+
-- table: subject
> select * from subject;
+------------+--------------+
| subject_id | subject_name |
+------------+--------------+
| 1 | Maths |
| 2 | Science |
| 3 | English |
| 4 | Telugu |
| 5 | Social |
+------------+--------------+
-- table: stu_subjects
> select * from stu_subjects;
+------------+------------+------------+
| stu_sub_id | student_id | subject_id |
+------------+------------+------------+
| 1 | 1 | 1 |
| 2 | 1 | 2 |
| 3 | 1 | 3 |
| 4 | 2 | 4 |
| 5 | 2 | 1 |
+------------+------------+------------+
-- query
> select a.student_id, b.student_name, group_concat(a.subject_id) as student_enrollment
from stu_subjects a, student b
where a.student_id = b.student_id
group by a.student_id, b.student_name;
+------------+--------------+--------------------+
| student_id | student_name | student_enrollment |
+------------+--------------+--------------------+
| 1 | Student-1 | 3,1,2 |
| 2 | Student-2 | 4,1 |
+------------+--------------+--------------------+

Answer 3

You can use simple join query to achieve this.
SELECT st.student_id,st.student_name,sb.subject_name
FROM student st
JOIN stu_subjects ss ON (ss.student_id = st.student_id)
JOIN Subject sb ON (ss.subject_id = sb.subject_id )
Also as you mentioned,if you want only for subject MySQL, then add below where condition
WHERE subject_name ='MySQL'
