我该如何解决“在这种情况下名称'X'是不允许的？”？

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，我想将两个值插入到M：M连接表中。 SELECT语句工作正常，我得到了期望的结果。 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

这是因为在INSERT的情况下，t1和t2不存在。

如果合并这两个问题，我认为它会做的正是你想要的东西：

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

根本不包括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

刚刚从insert into
