Question

您好我有一个查询，我在尝试将多个列连接成一列，同时加入一个表以将partnumber转换为ID。

我的查询有什么问题？

我收到错误

关键字“JOIN”附近的语法不正确。

但我不知道该如何说出来。

Select ID, Title
from dbo.features
unpivot
(
  Title
  for col in ([Features 1], [Features 2], [Features 3], [Features 4], [Features 5], [Features 6])
) un
order by partnumber, col;
(
JOIN    products.products
ON      Products.Products.PartNumber = dbo.features.PartNumber
)

Answer 1

...也许

Select F.ID Feature_ID, F.Title Feature_Title
from dbo.features
INNER JOIN    products.products
  ON Products.Products.PartNumber = dbo.features.PartNumber
unpivot
(
  Title
  for col in ([Features 1], [Features 2], [Features 3], [Features 4], [Features 5], [Features 6])
) un
order by partnumber, col;

但要回答这个问题：我的查询有什么问题？

<强>解答：您的连接语法错误。
