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.
