Kind of like "I heard a brake noise ... now my dog is limping ... Why?"

Please post the ddl of your table and all of the current constraints (including FKs).

Also post the actual "alter table " statement you wanted to execute.

I can't give you an answer to your question but I also has something similar to you. It errors out at my Insert Into statement. I believe it has something to do with the 'countries' table and the primary key that's inside which is 'country_code'.

This is the code that I put in:

set identity_insert customers on

select * from customers

insert into customers (custid, lname, fname, address, city, state, postal, country, mugshot, balance, monthly_fee)

values (101,'Johnson','Mike','101 Main st','Denver','CO','80231',0,null, 168.55, 25.00)

This is the error that I get:

(0 row(s) affected)

Msg 547, Level 16, State 0, Line 3

The INSERT statement conflicted with the FOREIGN KEY constraint "FK_customers_Countries". The conflict occurred in database "deptstore", table "dbo.Countries", column 'country_code'.

The statement has been terminated.

Can someone explain what this means. I'm sure if this is answered it will answer both of our questions, thanks.

Double check the country code you are inserting in your column 'country_code'.

It does not exist in your table Countries !!

In other words there is no pk in table Countries having a value of 0 (see your insert statement).
