Hi All... Two of my tables are:
Users - primary key is UserId, an int with identity turned on.
Messages - has a column named UserId that references the same in Users.
I'm using Visual Studio 2005 against a SQL 2005 database.
Using both the diagram tool and table data, I'm trying to set up the relationship implied above and am getting the following error:
Users table saved successfully.
Messages table
- unable to create relationship 'FK_Messages_UserId'.
The ALTER TABLE statement conflicted with the FOREIGN KEY constraint 'FK_Messages_UserId'. The conflict occurred in database 'XXXX', table 'dbo.Users', column 'UserId'.
I've done several other similar relationships without incident. But this one (and one or two others) refuse to work. I'm a bit of newbie with these rascals, so that doesnt help much... Any ideas what this things trying to tell me? Thanks! -- Curt
You might already have entries in your child table which have no parent entry in the parent table.HTH, Jens K. Suessmeyer.

Hi Jens... Thanks for the reply. You threw me a little at first on your use of "parent" and "child", but yeah you nailed it. To try and tie those terms to the tables in my original post, I had some records in Messages (child) that referenced a primary key that did not exist in Users (parent). Geez, these FKs really help us keep a clean house, dont they... Thanks again!! Curt
