INSERT 语句与 FOREIGN KEY 约束冲突 - SQL Server

问题描述

我收到以下错误.你能帮我吗?

I am getting the following error. Could you please help me?

消息 547，级别 16，状态 0，第 1 行
INSERT 语句与 FOREIGN KEY 约束FK_Sup_Item_Sup_Item_Cat"冲突.冲突发生在数据库dev_bo"、表dbo.Sup_Item_Cat"中.声明已终止.

Msg 547, Level 16, State 0, Line 1
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Sup_Item_Sup_Item_Cat". The conflict occurred in database "dev_bo", table "dbo.Sup_Item_Cat". The statement has been terminated.

代码:

insert into sup_item (supplier_id, sup_item_id, name, sup_item_cat_id, 
                      status_code, last_modified_user_id, last_modified_timestamp, client_id)   
values (10162425, 10, 'jaiso', '123123',
        'a', '12', '2010-12-12', '1062425')

最后一列 client_id 导致错误.我试图将 dbo.Sup_Item_Cat 中已经存在的值放入列中，对应于 sup_item.. 但没有喜悦 :-(

The last column client_id is causing the error. I tried to put the value which already exists in the dbo.Sup_Item_Cat into the column, corresponding to the sup_item.. but no joy :-(

推荐答案

在您的表 dbo.Sup_Item_Cat 中，它有一个指向另一个表的外键引用.FK 的工作方式是，它不能在该列中具有不在引用表的主键列中的值.

In your table dbo.Sup_Item_Cat, it has a foreign key reference to another table. The way a FK works is it cannot have a value in that column that is not also in the primary key column of the referenced table.

如果您有 SQL Server Management Studio，请打开它并sp_help 'dbo.Sup_Item_Cat'.查看 FK 位于哪一列，以及它引用哪个表的哪一列.您插入了一些错误数据.

If you have SQL Server Management Studio, open it up and sp_help 'dbo.Sup_Item_Cat'. See which column that FK is on, and which column of which table it references. You're inserting some bad data.

如果您需要更好的解释，请告诉我！
