The INSERT statement conflicted with the FOREIGN

Answer 1

You are trying to insert a record with a value in the foreign key column that doesn't exist in the foreign table.

For example: If you have Books and Authors tables where Books has a foreign key constraint on the Authors table and you try to insert a book record for which there is no author record.
