Question

创建表格

create table Empl(E_ID nvarchar(36) primary key, Name varchar(50), Designation varchar(50)) 

create table Location(L_ID nvarchar(36) primary key, Location varchar(50), E_ID nvarchar(36) foreign key references Empl(E_ID)) 

create table Contact_Emp (C_ID nvarchar(36) primary key, Contact_Number varchar(50), Lo_ID nvarchar(36) foreign key references Location(L_ID))

存储过程

alter proc InsertMultiplevalue  
(  
@Name varchar(50),  
@Designation varchar(50),  
@Location varchar(50),  
@Contact varchar(50)  
)  
as  
begin  
        insert into Empl values(newid(),@Name, @Designation)  
        declare @Employee_ID nvarchar(36) = NEWID()  
        insert into Location values(@Location,@Employee_ID)  
        declare @Cot_ID nvarchar(36) = NEWID()  
        insert into Contact_Emp values(@Contact,@Cot_ID)  
end

Ececute SP

exec InsertMultiplevalue 'UserName','Programmer','India','Admin@learn2Free.Com'

我收到此错误

消息547，级别16，状态0，过程InsertMultiplevalue，第25行 INSERT语句与FOREIGN KEY约束“FK__Location__E_ID__33D4B598”冲突。冲突发生在数据库中 “LocalDBTest”，表“dbo.Empl”，列'E_ID'。该语句已终止。消息547，级别16，状态0，过程InsertMultiplevalue，第27行 INSERT语句与FOREIGN KEY约束“FK__Contact_E__Lo_ID__36B12243”冲突。冲突发生在数据库中 “LocalDBTest”，表“dbo.Location”，列“L_ID”。

STore程序的变化是否有效

alter proc InsertMultiplevalue  
(  
@Name varchar(50),  
@Designation varchar(50),  
@Location varchar(50),  
@Contact varchar(50)  
)  
as  
begin  
          declare @Employee_ID nvarchar(36) = NEWID()  
        insert into Empl values(@Employee_ID,@Name, @Designation)  

        declare @Location_ID nvarchar(36) = NEWID() 
        insert into Location values(@Location_ID,@Location,@Employee_ID)  

        declare @Cot_ID nvarchar(36) = NEWID()  
        insert into Contact_Emp values(@Cot_ID,@Contact,@Location_ID)  
end

插入NEWID（）ID的运行时，在运行Store Procedure时出现FOREIGN KEY约束错误
