SqlException: The INSERT statement conflicted with the FOREIGN KEY constraint . The conflict occurred in database , column 'If'. The statement has been terminated. code example

Example: sqlexception: the insert statement conflicted with the foreign key constraint

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.

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.

Let me know if you need anything explained better!
