透视不显示交叉表

Question

我坚持这个： （1）在第2行收到有关＆＃39;无效列名＆＃39; book_id＆＃39;＆＃39;的错误。我需要在publ_id之后列出book_id。 （2）获取max（list_price）值的空值。

select publ_id 'Publ'
  , book_id as 'Book'
  , [1] as 'Price1'
  , [2] as 'Price2'
  , [3] as 'Price3'
  , [4] as 'Price4'
from
(
  select publ_id, book_id, title, list_price
  from bkinfo.books 
) tbl   
pivot
( 
  max(list_price) for book_id in([1],[2],[3],[4])
)p
;
go

Answer 1

看起来您的代码缺少“as”：

Select publ_id 'Publ'
  , book_id as 'Book

这可能是你应该拥有的：

Select publ_id as 'Publ'
  , book_id as 'Book
