Question

我对SqL的世界相当新，我有这个常见的问题，大多数人似乎已修复，但我无法，当插入数据我得到错误1452，我在这里尝试下面的步骤PopOver displayed correctly

每个解决方案都失败了，这是我的SqL脚本：

# Author: Waheed Rafiq
# Date: 02/04/2016
# testX database
# list to Create tables 

# tbl_Admin 
create table tbl_admin(
adminID smallint not null  primary key auto_increment,
employeeID smallint null ,
admin_employee_Fname varchar(20),
admin_employee_Sname varchar(20),

admin_accessRight enum ('standard','accounts','classic','admin')
); 
# add dummy data :
insert tbl_admin values(1,1,'Waheed','Rafiq','admin');
insert tbl_admin values(2,2,'Sarah','Rafiq','classic');
insert tbl_admin values(3,3,'Philps','Smiths','standard');
insert tbl_admin values(4,4,'John','Edwards','standard');
insert tbl_admin values(5,5,'Ash','Codi','accounts');
insert tbl_admin values(6,6,'Kath','Womi','admin');

# tbl_employee 
create table tbl_employee(
employeeID smallint not null  primary key auto_increment,
adminID smallint null,
employee_Fname varchar(20),
employee_Sname varchar(20),
employee_AddressL1 varchar(100),
employee_AddressL2 varchar(100),
employee_PostCode varchar(10),
employee_tel_type enum ('work','personal','other'),
employee_telephone varchar(30) ,
employee_JobRole varchar(20),
employee_Salary float

); 

# add dummpy data to employee table

 insert tbl_employee values(1,1,'Waheed','Rafiq','36 do thed        road','Alcala','2345','work','07525177630','Admin','60.568');
insert tbl_employee values(2,2,'Sarah','Rafiq','126 Cala de  Polo','Alcala','4345','personal','034525177630','Office Admin','1.568');
insert tbl_employee values(3,3,'Philps','smiths','367 fake de pounda','Alcala','345','work','09258177630','Maintance','15.568');
insert tbl_employee values(4,4,'John','Edwards','36 Greader los OSO','Madrid','1045','work','07525177888','office clark','2.568');
insert tbl_employee values(5,5,'Ash','Codi','88 do thed road','Alcala','2345','work','07528547858','Finance','30.568');
insert tbl_employee values(6,6,'Kath','Womi','555 Gotham road','Madrid','1111','work','07525177999','Admin Techi','40.568');

# check up to this point all works fine dummpy data is added.

现在我添加FK键：在单独的脚本中

# Author: Waheed Rafiq
# Date: 02/04/2016
# testx database
# Add list of FK to database.

#FK to tbl_admin

alter table blindx_test1.tbl_admin add foreign key（employeeID）引用tbl_employee（employeeID）;

＃将FK添加到tbl_admin

alter table blindx_test1.tbl_employee add foreign key(adminID) references  tbl_admin(adminID);

这部分工作正常，现在这里是将新数据插入表中的问题我得到错误代码1452：

insert tbl_admin values( 7,7,'Samia','Fazal','admin');

insert tbl_employee values(7,7 ,'Samia','Fazal','786 Bromford    Lane','Madrid','1110','other','07525177999','Admin Techi','40.568');

任何帮助或支持，都会非常感激，这么简单的事情现在变得很难:(我相信你们能够发现它显而易见的东西。

感谢您的支持。如果我发现有人会更新我的帖子，我会继续寻找解决方案。

Answer 1

对于此查询：

insert tbl_admin values( 7,7,'Samia','Fazal','admin');

阅读整个错误：

无法添加或更新子行：外键约束失败（db_9_3137a。tbl_admin，CONSTRAINT tbl_admin_ibfk_1 FOREIGN KEY （employeeID）参考tbl_employee（employeeID））

这很清楚。您正尝试在employeeID中插入值7。没有这样的值，所以你得到错误。

Here是一个SQL小提琴，代码最后两个插入。
