JOIN FOUR TABLES in mysql. Error in syntax - mysql

Question

I need to join four tables in mysql.
My database structure:
DROP DATABASE IF EXISTS db_applicant;
CREATE DATABASE db_applicant
DEFAULT CHARACTER SET 'utf8'
DEFAULT COLLATE 'utf8_unicode_ci';
USE db_applicant;
--
-- TABLE: PROFESSION
--
CREATE TABLE PROFESSION (
PROFESSION_ID INT NOT NULL AUTO_INCREMENT,
PROFESSION_NAME VARCHAR(50) NOT NULL,
PRIMARY KEY (PROFESSION_ID)
);
--
-- TABLE: SUBJECT
--
CREATE TABLE SUBJECT (
SUBJECT_ID INT NOT NULL AUTO_INCREMENT,
SUBJECT_NAME VARCHAR(50) NOT NULL,
PRIMARY KEY (SUBJECT_ID)
);
--
-- TABLE: APPLICANT
--
CREATE TABLE APPLICANT (
APPLICANT_ID INT NOT NULL AUTO_INCREMENT,
PROFESSION_ID INT NOT NULL,
LAST_NAME VARCHAR(30) NOT NULL,
FIRST_NAME VARCHAR(30) NOT NULL,
ENTRANCE_YEAR INT NOT NULL,
PRIMARY KEY (APPLICANT_ID),
FOREIGN KEY (PROFESSION_ID) REFERENCES PROFESSION (PROFESSION_ID)
);
--
-- TABLE: APPLICANT_RESULT
--
CREATE TABLE APPLICANT_RESULT (
APPLICANT_RESULT_ID INT NOT NULL AUTO_INCREMENT,
APPLICANT_ID INT NOT NULL,
SUBJECT_ID INT NOT NULL,
MARK INT,
PRIMARY KEY (APPLICANT_RESULT_ID),
FOREIGN KEY (SUBJECT_ID)
REFERENCES SUBJECT (SUBJECT_ID),
FOREIGN KEY (APPLICANT_ID)
REFERENCES APPLICANT (APPLICANT_ID)
);
--
-- TABLE: SPECIALITY_SUBJECT
--
CREATE TABLE SPECIALITY_SUBJECT (
SP_SB_ID INT NOT NULL AUTO_INCREMENT,
PROFESSION_ID INT NOT NULL,
SUBJECT_ID INT NOT NULL,
PRIMARY KEY (SP_SB_ID),
FOREIGN KEY (PROFESSION_ID)
REFERENCES PROFESSION (PROFESSION_ID),
FOREIGN KEY (PROFESSION_ID)
REFERENCES PROFESSION (PROFESSION_ID),
FOREIGN KEY (SUBJECT_ID)
REFERENCES SUBJECT (SUBJECT_ID)
);
I need that output would be something like:
first_name (this column from table applicant), last_name (this column from table applicant), entrance_year (this column from table applicant), profession_name (this column from table profession), subject_name (this column from table subject), mark (this column from table applicant_result).
You can see, that i have related fields. But i need strong INNER QUERY.
For that, i create new table with structure:
CREATE TABLE APP(
ALL_ID INT NOT NULL AUTO_INCREMENT,
APPLICANT_ID INT NOT NULL,
SUBJECT_ID INT NOT NULL,
PROFESSION_ID INT NOT NULL,
APPLICANT_RESULT_ID INT NOT NULL,
PRIMARY KEY (ALL_ID),
FOREIGN KEY (SUBJECT_ID)
REFERENCES SUBJECT (SUBJECT_ID),
FOREIGN KEY (APPLICANT_ID)
REFERENCES APPLICANT (APPLICANT_ID),
FOREIGN KEY (PROFESSION_ID)
REFERENCES PROFESSION (PROFESSION_ID),
FOREIGN KEY (APPLICANT_RESULT_ID)
REFERENCES APPLICANT_RESULT (APPLICANT_RESULT_ID)
);
And my inner:
SELECT ap.ALL_ID, a.FIRST_NAME, a.LAST_NAME,
a.ENTRANCE_YEAR, p.PROFESSION_NAME s.SUBJECT_NAME, ar.MARK
FROM app ap
JOIN (applicant a, profession p, subject s, applicant_result ar)
ON ap.APPLICANT_ID = a.APPLICANT_ID
AND ap.SUBJECT_ID = s.SUBJECT_ID
AND ap.PROFESSION_ID = p.PROFESSION_ID
AND ap.APPLICANT_RESULT_ID = ar.APPLICANT_RESULT_ID;
But i have error:
[2015-09-19 10:08:52] [42000][1064] 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 '.SUBJECT_NAME, ar.MARK FROM app ap
JOIN (applicant a, profession p, subject s, a' at line 1

Answer 1

Don't you think, a comma ',' is missing here in select statement before s.SUBJECT_NAME?
SELECT ap.ALL_ID, a.FIRST_NAME, a.LAST_NAME,
a.ENTRANCE_YEAR, p.PROFESSION_NAME s.SUBJECT_NAME, ar.MARK
