как объединить 4 таблицы для правильного объединения в phpmysql?

Question

У меня возникла проблема с синтаксисом соединения четырех таблиц с использованием RIGHT JOIN:

SELECT personal.ExamineeID, personal.FirstName, personal.MiddleName, personal.LastName, personal.Age, personal.HomeAddress, personal.ContactNumber, senior.LastSchoolAttended, senior.Strand, senior.SchoolAddress,senior.Adviser, senior.Honor1, senior.Honor2, senior.Honor3, senior.Honor4, parent.Father, parent.EducationalFather, parent.Mother, parent.EducationalMother, parent.Guardian, parent.Occupation, score.Score, score.Rank, score.ExamTime
  FROM
  personal
  RIGHT JOIN senior, parent, score
  ON
  personal.ExamineeID = senior.ExamineeID
  personal.ExamineeID = parent.ExamineeID
  personal.ExamineeID = score.ExamineeID
  ORDER BY personal.ExamineeID

Это мой код, и я хочу присоединиться к таблице, которая является личной, старшей , родитель и оценка.

Answer 1

Объединение таблиц в SQL принимает только один аргумент, отметьте эту ссылку SQL , чтобы узнать больше об операторах JOIN.

SELECT personal.ExamineeID, personal.FirstName, 
personal.MiddleName, personal.LastName, personal.Age,
 personal.HomeAddress, personal.ContactNumber, senior.LastSchoolAttended,
 senior.Strand, senior.SchoolAddress,senior.Adviser, 
senior.Honor1, senior.Honor2, senior.Honor3, 
senior.Honor4, parent.Father, parent.EducationalFather, 
parent.Mother, parent.EducationalMother, parent.Guardian, parent.Occupation, score.Score, score.Rank, score.ExamTime
      FROM personal
      RIGHT JOIN senior ON personal.ExamineeID = senior.ExamineeID
      RIGHT JOIN parent ON personal.ExamineeID = parent.ExamineeID
      RIGHT JOIN score ON personal.ExamineeID = score.ExamineeID
      ORDER BY personal.ExamineeID
