试图正确插入数据

Question

从模糊棒棒糖收到非常好的修正后，我修改了我的代码，为每行数据创建插入语句。这是我输入的代码：

INSERT DEPARTMENTS 
(Department_Id,Department_Name,Manager_Id,Location_Id) 
VALUES 
('D0001','Think Tank',NULL,'L0001') 
GO 

INSERT DEPARTMENTS 
(Department_Id,Department_Name,Manager_Id,Location_Id) 
VALUES 
('D0002','Creators',NULL,'L0002') 
GO 

INSERT DEPARTMENTS 
(Department_Id,Department_Name,Manager_Id,Location_Id) 
VALUES 
('D0003','Marketers',NULL,'L0003') 
GO 

INSERT EMPLOYEES 
(Employee_Id,First_Name,Last_Name,Email,PhoneNumber,Hire_Date,Manager_ID,Department_Id) 
VALUES 
('E0001','Joe','Blow',NULL,NULL,2010/06/25,NULL,NULL) 
GO 

INSERT EMPLOYEES 
(Employee_Id,First_Name,Last_Name,Email,PhoneNumber,Hire_Date,Manager_ID,Department_Id) 
VALUES 
('E0002','John','Doe',NULL,NULL,2010/06/25,NULL,NULL) 
GO 

INSERT EMPLOYEES 
(Employee_Id,First_Name,Last_Name,Email,PhoneNumber,Hire_Date,Manager_ID,Department_Id) 
VALUES 
('E0003','Sue','Happy',NULL,NULL,2010/06/25,NULL,NULL) 
GO 

INSERT EMPLOYEES 
(Employee_Id,First_Name,Last_Name,Email,PhoneNumber,Hire_Date,Manager_ID,Department_Id) 
VALUES 
('E0004','Tina','Turner',NULL,NULL,2010/06/25,NULL,NULL) 
GO 

INSERT EMPLOYEES 
(Employee_Id,First_Name,Last_Name,Email,PhoneNumber,Hire_Date,Manager_ID,Department_Id) 
VALUES 
('E0005','Ike','Turner',NULL,NULL,2010/06/25,NULL,NULL) 
GO 

INSERT EMPLOYEES 
(Employee_Id,First_Name,Last_Name,Email,PhoneNumber,Hire_Date,Manager_ID,Department_Id) 
VALUES 
('E0006','Big','Bird',NULL,NULL,2010/06/25,NULL,NULL) 
GO 

INSERT EMPLOYEES 
(Employee_Id,First_Name,Last_Name,Email,PhoneNumber,Hire_Date,Manager_ID,Department_Id) 
VALUES 
('E0007','Speedy','Gonzales',NULL,NULL,2010/06/25,NULL,NULL) 
GO 

然而，这些是我收到错误消息：

Msg 547, Level 16, State 0, Line 1 
The INSERT statement conflicted with the FOREIGN KEY constraint "FK__DEPARTMEN__Locat__09DE7BCC". The conflict occurred in database "Final_Project", table "dbo.LOCATIONS", column 'Location_ID'. 
The statement has been terminated.

我不会没有立即响应解决方案犯同样的错误。我不知道检查绿色复选标记意味着答案是令人满意的。

感谢您的帮助

Answer 1

你有两种不同类型的错误。

首先是您违反了外键约束。有三种方法来解决这个问题：

• 找出正确的密钥应该是什么（例如通过查询LOCATIONS表），并改变你的外键正确的值。
• 在插入DEPARTMENTS之前，在LOCATIONS表中插入缺失的行。
• 删除约束（这可能是一个坏主意）。

第二个错误更简单 - 您错误地格式化了日期。它应该是一个字符串。

'2010-06-25' 

完整的查询：

INSERT EMPLOYEES 
(Employee_Id,First_Name,Last_Name,Email,PhoneNumber,Hire_Date,Manager_ID,Department_Id) 
VALUES 
('E0001','Joe','Blow',NULL,NULL,'2010-06-25',NULL,NULL) 

Answer 2

1）有与位置表中给出LocationIDs没有记录

2）你需要引用的日期值

Answer 3

• 是否有部门和位置之间的外键约束。如果是这样，那么插入一个部件需要一个现有的位置。地点连接到同系LOCATION_ID

• 时间戳语法应为一个字符串'12/12/2010' 离不开“-signs
