Sql 完整性约束错误再次出现

我通过以下模式创建了四个数据库表，但得到了一个完整性约束冲突错误。以下是我的整个架构以及填充表的查询：

create table Employee(
    Lastname    varchar(10),
    FirstName   varchar(10),
    MidInitial  char(1),

下面是我再次遇到的错误：

Schema Creation Failed: ORA-02291: integrity constraint (USER_4_3C8F2.SYS_C00778260) violated - parent key not found

这将是伟大的，让另一套眼睛来看看这一点，看看是什么错了它。。。我想知道我是否应该按照不同的顺序创建/填充表，但我认为我所做的是正确的

非常感谢您的帮助。谢谢

----更新----我也在使用SQL Fiddle和Oracle 11g R2。

这是您的问题：

insert into Works values('Gill', 'Mary', 'L', 'Union Pacific', 48700);

“联合太平洋”不是您的公司之一，您有“联合太平洋（UP）”

顺便说一句，无论如何，这是一种非常糟糕的方式。像这样跨表复制数据将意味着您会一次又一次地遇到这样的问题

您的每个参考数据表（

Employee

&

Company

）都应该有一个代理键，而您的详细信息表（

Works

和

Manages

）应该使用这些代理键。例如：

create table Employee(
    Id          numeric(8),
    Lastname    varchar(10),
    FirstName   varchar(10),
    MidInitial  char(1),
    gender      char(1),
    street      varchar(10),
    city        varchar(10),
    primary key(Id));

嗯。注意到一些错误

insert into Works 
    values('Gill', 'Mary', 'L', 'Union Pacific (UP)', 48700);
insert into Works
    values('Harrison', 'Susan', 'M', 'Union Pacific (UP)', 54320);

--将“联合太平洋”更改为“联合太平洋（UP）”

---

--将所有双引号更改为单引号

确定。注意到一些错误

insert into Works 
    values('Gill', 'Mary', 'L', 'Union Pacific (UP)', 48700);
insert into Works
    values('Harrison', 'Susan', 'M', 'Union Pacific (UP)', 54320);

foreign key(Lastname, FirstName, MidInitial) references Employee**(column)**

--将“联合太平洋”更改为“联合太平洋（UP）”

--将所有双引号更改为单引号

foreign key(Lastname, FirstName, MidInitial) references Employee**(column)**

您忘记了“员工”列

您忘记了Employee列。

似乎您正在尝试向子表插入一个值，但该值在父表中不存在。再次尝试重新验证数据集。似乎您正在尝试向子表插入一个值，但该值在父表中不存在。再次尝试重新验证您的数据集。谢谢，谢谢您提供了更好的方法来编写数据集。。。我修复了错误，但是现在我在尝试构建模式时遇到了这个错误：模式创建失败：ORA-00984:列此处不允许有任何关于这个的想法？再次感谢。请参考我的帖子。。。您的所有语句都已使用原始模式在@user1462294处修复？根据@realspirituals@David-说得好，我有点匆忙，忘了做那件事。。我编辑了这篇文章。虽然没有添加任何独特的约束，但如果他/她选择更改其设计，将由OP决定。谢谢，谢谢你提供了更好的方式来编写它。。。我修复了错误，但是现在我在尝试构建模式时遇到了这个错误：模式创建失败：ORA-00984:列此处不允许有任何关于这个的想法？再次感谢。请参考我的帖子。。。您的所有语句都已使用原始模式在@user1462294处修复？根据@realspirituals@David-说得好，我有点匆忙，忘了做那件事。。我编辑了这篇文章。但是，如果没有添加任何独特的约束，那么如果OP选择更改其设计，他/她将自行决定。。
