它的Access数据库..

我有一个库表，其中Autnm Topic Size Cover Lang是外键

每条记录实际上是一本书，具有其属性，例如作者和资料。我不太确定我什至使用了正确的 JOIN .. 非常新的“复杂”SQL :)

SELECT Library.Bknm_Hebrew, Library.Bknm_English, Library.Bknm_Russian, Library.Note,
       Library.ISBN, Library.Pages, Library.PUSD, Author.ID AS [AuthorID],
       Author.Author_hebrew AS [AuthorHebrew],
       Author.Author_English AS [AuthorEnglish],
       Author.Author_Russian AS [AuthorRussian], Topic.ID AS [TopicID],
       Topic.Topic_Hebrew AS [TopicHebrew], Topic.Topic_English AS [TopicEnglish],
       Topic.Topic_Russian AS [TopicRussian], Size.Size AS [Size],
       Cover.ID AS [CoverID], Cover.Cvrtyp_Hebrew AS [CoverHebrew],
       Cover.Cvrtyp_English AS [CoverEnglish], Cover.Cvrtyp_Russian AS [CoverRussian],
       Lang.ID AS [LangID], Lang.Lang_Hebrew AS [LangHebrew],
       Lang.Lang_English AS [LangEnglish],

FROM Library INNER JOIN Author ON Library.Autnm = Author.ID
                 INNER JOIN Topic ON Library.Topic = Topic.ID
                 INNER JOIN Size ON Library.Size = Size.ID
                 INNER JOIN Cover ON Library.Cover = Cover.ID
                 INNER JOIN Lang ON Library.Lang = Lang.ID
WHERE (TopicID=13 AND LangID=1) ORDER BY LangID ASC

编辑： 插入@Guffa建议的括号后，我收到了一个新错误：

Too few parameters. Expected 3.

在 Access 中，如果您有多个联接，则需要括号。此外，正如 Ivar 指出的那样，在字段列表中的最后一项之后有一个额外的逗号。

select
  Library.Bknm_Hebrew, Library.Bknm_English, Library.Bknm_Russian, Library.Note,
  Library.ISBN, Library.Pages, Library.PUSD, Author.ID as [AuthorID],
  Author.Author_hebrew as [AuthorHebrew], Author.Author_English as [AuthorEnglish],
  Author.Author_Russian as [AuthorRussian], Topic.ID as [TopicID],
  Topic.Topic_Hebrew as [TopicHebrew],  Topic.Topic_English as [TopicEnglish],
  Topic.Topic_Russian as [TopicRussian], Size.Size as [Size], Cover.ID as [CoverID],
  Cover.Cvrtyp_Hebrew as [CoverHebrew], Cover.Cvrtyp_English as [CoverEnglish],
  Cover.Cvrtyp_Russian as [CoverRussian], Lang.ID as [LangID],
  Lang.Lang_Hebrew as [LangHebrew], Lang.Lang_English as [LangEnglish]  
from
  (((((Library
  inner join Author on Library.Autnm = Author.ID)
  inner join Topic on Library.Topic = Topic.ID)
  inner join Size on Library.Size  = Size.ID)
  inner join Cover on Library.Cover = Cover.ID)
  inner join Lang on Library.Lang  = Lang.ID)

编辑：

The error message "Too few parameters." means that you have defined parameters in the query that is not sent along when it's executed. As you don't use any parameters in the query it means that you have spelled some names in the query wrong, so that it thinks that they are parameters instead.

我对 Access 不太熟悉，因此不确定它是否接受这一点，但我会先从选择列表中删除最后一个逗号。

Lang.Lang_English AS [LangEnglish], => Lang.Lang_English AS [LangEnglish]
