Réécrivez l'instruction SQL de USING à ON

Question

Hé les gars. Avoir des problèmes ici. Avoir des webhotels avec les mêmes versions de MySQL et PHPmyadmin, mais réagit différemment. Mayb quelque chose avec le MySQL.ini.

Comment puis-je réécrire ceci sur ON, à partir de Using.

SELECT wiederquist_elearn_question.idelearn_question AS idelearn_question, idelearn_answer, idelearn_user, name, email, address, zip, city, phone, extra, user_created_time, newsletter, answertime, title, description, illustration, answertext, correct 
FROM wiederquist_elearn_user 
INNER JOIN wiederquist_elearn_question_answered 
USING (idelearn_user) 
INNER JOIN wiederquist_elearn_question 
USING (idelearn_question) 
INNER JOIN wiederquist_elearn_answer 
USING (idelearn_answer) 
WHERE name IS NOT NULL 
AND idelearn =1 

J'espère que vous pouvez m'aider ici.Merci.

Edit:

Maintenant, j'ai eu, mais il montre 11.700 résultats, et il ne devrait montrer 2. Mais ce sont les bons résultats, leur juste boucle.

Answer 1

Vous devez utiliser INNER JOIN jointablename SUR jointablename.join_id = tablename.id, pour ce cas requête ressemble à:

SELECT weq.idelearn_question AS idelearn_question, idelearn_answer, weu.idelearn_user 
as idelearn_uder, name, email, address, zip, city, phone, extra, user_created_time, 
newsletter, answertime, title, description, illustration, answertext, correct 
    FROM wiederquist_elearn_user AS weu 
     INNER JOIN wiederquist_elearn_question_answered AS weqa 
      ON weu.idelearn_user = weu.idelearn_user 
     INNER JOIN wiederquist_elearn_question AS weq 
      ON weq.idelearn_question = (table your need to join).idelearn_question 
and so on.. 

Answer 2

Je l'ai fait ! yay

SELECT wiederquist_elearn_question.idelearn_question AS idelearn_question, wiederquist_elearn_answer.idelearn_answer, wiederquist_elearn_user.idelearn_user, name, email, address, zip, city, phone, extra, user_created_time, newsletter, answertime, title, description, illustration, answertext, correct 
FROM wiederquist_elearn_user 
INNER JOIN wiederquist_elearn_question_answered 
USING (idelearn_user) 
INNER JOIN wiederquist_elearn_question 
USING (idelearn_question) 
INNER JOIN wiederquist_elearn_answer ON wiederquist_elearn_answer.idelearn_answer = wiederquist_elearn_question_answered.idelearn_answer 
WHERE name IS NOT NULL and idelearn = 1 

Merci les gars
