Sql Server中的简单存储过程：插入到桥接表中

我对以下存储过程有问题。只要我不取消最后一次插入的注释，它就可以正常运行。如果取消最后一次插入的注释，则会出现以下错误：

Msg 547，16级，状态0，程序 插入RecipeWithTags，第42行 INSERT语句与 外键约束 “FK_Tag_Tag配方”。冲突 发生在数据库“RecipeBox”中， 表“RecipedDetails.Tag”，第列 “tagID”。声明已被修改 终止

为了澄清，我有三个表格：

recipe(id, title, introduction, directions)
recipeTag(id, recipeID, tagID)
tag(id, name)

因此，如果我尝试插入到

recipeTag

表中，就会出现上述错误。请告知

谢谢

CREATE PROCEDURE [RecipeDetails].[InsertRecipeWithTags]
/*
    variables that map to columns
*/
@title varchar(50),
@intro varchar(255),
@directions varchar(2200),
@ingredients varchar(2200),
@difficulty varchar(6), /*need check constraint setting difficulty to "beginner" "medium" or "expert"*/
@prepTimeHour tinyint,
@prepTimeMinute tinyint,
@inactiveTimeHour tinyint,
@inactiveTimeMinute tinyint,
@servings tinyint,
@photo varbinary(MAX),
@tagName varchar(50),
@tagdescription varchar(255)

AS

BEGIN
    SET NOCOUNT ON;

    DECLARE @RecipeID int, @TagID int

    INSERT INTO RecipeDetails.Recipe (title, intro,directions, ingredients, difficulty, 
    prepTimeHour, prepTimeMinute, inactiveTimeHour, inactiveTimeMinute, servings, photo)
    VALUES (@title, @intro,@directions, @ingredients, @difficulty, @prepTimeHour, @prepTimeMinute,
    @inactiveTimeHour, @inactiveTimeMinute, @servings, @photo)

    SELECT @RecipeID=SCOPE_IDENTITY()

    SELECT * FROM RecipeDetails.Recipe WHERE recipeID = @RecipeID;

    INSERT INTO RecipeDetails.Tag (name, description)
    VALUES (@tagName, @tagdescription)

    SELECT @TagID=SCOPE_IDENTITY()

    SELECT * FROM RecipeDetails.Tag WHERE tagID = @TagID;

    /*INSERT INTO RecipeDetails.TagRecipe (tagID, recipeID)
    VALUES (@RecipeID, @TagID)*/
END

颠倒顺序

INSERT INTO RecipeDetails.TagRecipe (tagID, recipeID)
VALUES (@TagID, @RecipeID)

你当时走错了方向，是不是颠倒了顺序

INSERT INTO RecipeDetails.TagRecipe (tagID, recipeID)
VALUES (@TagID, @RecipeID)

你当时走错了路

就是这样！谢谢我还是个新手，这对我很有帮助！就这样！谢谢我还是个新手，这对我很有帮助！
