MySQL Syntax Error for a complex query - mysql

Question

Here is the complex query that I wrote but can't figure out what's the problem:
SELECT student.progid,
student.batch
FROM (student
JOIN registers
ON student.studentid = registers.studentid)
JOIN (SELECT offers.courseno
FROM (offers
JOIN instructor
ON offers.instructorid = instructor.instructorid))
ON offers.courseno = registers.courseno
WHERE instructor.instructorname = 'P M Jaat'
AND ( offers.acadyear LIKE '2007%'
OR offers.acadyear LIKE '2008%'
OR offers.acadyear LIKE '2009%'
OR offers.acadyear LIKE '2010%'
OR offers.acadyear LIKE '2011%' );
This results in an error, but I'm going to leave it to others to tell you what that is:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds
to your MySQL server version for the right syntax to use near 'R1
JOIN (SELECT

Answer 1

Double check your parenthesis. Your FROM clause is
(student JOIN registers ON student.StudentID=registers.StudentID)
Which doesn't make sense.
What you want is:
FROM (student)
JOIN registers AS r1
ON (student.StudentID=registers.StudentID)
Or you can just lose the extra parenthesis:
FROM student
JOIN registers AS r1
ON student.StudentID=registers.StudentID
P.S. You also had your AS r1 in the wrong spot.
UPDATE: You need parenthesis when you are using subqueries.
FROM student
JOIN registers
ON student.studentid = registers.studentid
JOIN(
SELECT courseno
FROM offers
JOIN instructor
ON offers.instructorid = instructor.instructorid
) AS r2 ON offers.courseno = registers.courseno

Answer 2

Perhaps you're after something like this...
SELECT r.progid
, r.batch
FROM student s
JOIN registers r
ON r.studentid = s.studentid
JOIN offers o
ON o.courseno = r.courseno
JOIN instructor i
ON i.instructorid = o.instructorid
WHERE i.instructorname = 'P M Jaat'
AND o.acadyear BETWEEN '2007-01-01' AND '2011-12-31';
