Foreign Key Constraint Error / Parent Record Does Exist But Won't Let Child Record Be Created
Feb 21, 2010While I've previously many years of relational databases and procedural languages, I'm stumbling with Visual Basic. In this problem, the simple situation is that I have two files, parent and child. The primary key of the parent file (Area file) is linked by a relation to one of the two fields that makes up the primary key in the child file (Project file) (unique key is formed from 'area' and 'project'). I have the default table adapters created on both files. I have created two maintenance forms showing one each of the two files in datagrid view format.I can create some records in the Parent (Area) file, but when I try to create a record in the child (Project) file, using one of the valid key values from the Area file, I get the 'ForeignKeyConstraint [relation name] requires the child key values [actual value] to exist in the parent table' which I'm absolutely definitely sure it does.
I haven't done any actual coding for those two maintenance forms, just dragged-and-dropped the files from the data sources screen onto separate forms so it creates the controls itself. But I can't work out, if it already knows the data does exist because I can load it back in to the Area maintence form, why it can't check itself to find out the record does exist. Why does it think the record from the parent record doesn't exist? It does exactly the same thing, whether or not the database is in access or SQL Server Express. I have all the latest updates.
Database Control Binding - Create A Record Add Information To It And Click On Next Record

Trying To Save New Record In DB Gives Error
May 4, 2009I have it mostly working right now, I can edit existing data and have it save to the database so when I re-open the program all the new data is still there. Now I get an error saying "Column 'AppID' does not allow nulls." when I try to create a new record. AppID is a column in the DB that I use to number the appointments. I guess it's looking for this value when it tries to save the new data, and since it isn't a field on the form it doesn't get an entry and fires that message. I've tried changing the AppID column to an AutoNumber field so it generates by itself but I still get the same error.
