这个SQL语句出了什么问题？

Question

SELECT * FROM Questions 
INNER JOIN QuestionKeyword INNER JOIN Keywords
ON Questions.ID=QuestionKeyword.QuestionID 
AND QuestionKeyword.KeywordID=Keywords.ID
WHERE Keywords.Keyword LIKE '%es%'

它说:关键字'WHERE'附近的语法不正确.

Answer 1

您无法组合来自多个JOIN的条件,但必须使用每个连接单独列出它们:

SELECT * FROM Questions 
INNER JOIN QuestionKeyword ON Questions.ID=QuestionKeyword.QuestionID
INNER JOIN Keywords  ON QuestionKeyword.KeywordID=Keywords.ID
WHERE Keywords.Keyword LIKE '%es%'
