Hi

I have a typed DataSet that contains two tables. The second table has a
foreign key that refers to the primary key of the first table. When i fill
the first table there is no problem. But when i fill the second table i get
the following error:

Failed to enable constraints. One or more rows contain values violating
non-null, unique, or foreign-key constraints.

Many thanks in advance
 
Bert:

That error typically means that something isn't kosher in the second table,
either a key value that's not present in the parent or a null value. If you
are positive neither case exists, I'd run a where clause on both queries and
try to narrow down what will work and what won't to determine where the
problem is.

HTH,

Bill
