Question

INSERT INTO dbo.VehiclesCategories ( VehicleId, CategoryId )
VALUES ( t1.ID , t2.ID)

SELECT t1.ID, t2.ID
FROM dbo.Vehicle t1
inner JOIN dbo.VehicleCategory t2 ON t1.Category = t2.Name

在上面的SQL中，我想在M：M连接表中插入两个值。 SELECT语句工作正常，我得到了所需的结果。 INSERT语句抛出以下错误：

Msg 128, Level 15, State 1, Line 2
The name "t1.ID" is not permitted in this context. Valid expressions are constants, constant expressions, and (in some contexts) variables. Column names are not permitted.

如何将两个值（t1.ID和t2.ID）插入表中？

Answer 1

那是因为在INSERT的上下文中，t1和t2不存在。

如果你将这两个查询结合起来，我认为它会完全符合你的要求：

INSERT INTO dbo.VehiclesCategories ( VehicleId, CategoryId )
SELECT t1.ID, t2.ID
FROM dbo.Vehicle t1
inner JOIN dbo.VehicleCategory t2 ON t1.Category = t2.Name

Answer 2

根本不要包含VALUES (t1.ID, t2.ID)部分。

Answer 3

试试这个

INSERT dbo.VehiclesCategories ( VehicleId, CategoryId )  
SELECT t1.ID, t2.ID 
FROM dbo.Vehicle t1 
JOIN dbo.VehicleCategory t2 ON t1.Category = t2.Name

Answer 4

只需从VALUES ( t1.ID , t2.ID)

中删除insert into即可

我如何修复“在此上下文中不允许使用名称'X'”？
