您是否可以在内部联接表上使用where约束来限制结果？

Question

解决

sql = "SELECT Title, Year, TmdbId, MovieFileId, Quality " \
      "FROM Movies " \
      "INNER JOIN MovieFiles on MovieFiles.Id = Movies.MovieFileId " \
      "WHERE Quality = 7"

sql = "SELECT Title, Year, TmdbId, MovieFileId, MovieFiles.Quality " \
      "FROM Movies " \
      "INNER JOIN MovieFiles on MovieFiles.Id = Movies.MovieFileId " \
      "WHERE MovieFiles.Quality = 7"

这些都不适合我，我没有返回任何行。质量是MovieFiles表的一部分。是的，存在符合此标准的行。

sql = "SELECT Title, Year, TmdbId, MovieFileId, Quality " \
      "FROM Movies " \
      "INNER JOIN MovieFiles on MovieFiles.Id = Movies.MovieFileId "

这很好用，并返回正确的质量。但是，如果我添加where，它不起作用，只返回任何内容。难道我做错了什么？ （使用python）
