Hi WonderMan,

it a database constraint or a dataset constraint ?

As for database constraint, you can check it using the 'Check Constraint
Dialog Box'. For more information on how to use this dialog box, please
refer to the following MSDN document:

'Check Constraint Dialog Box'
http://msdn2.microsoft.com/en-us/library/8kc2z88w.aspx

As for dataset constraint, it refers to unique constraint and foreign key
constraint. You can create a unique constraint by defining a primary key in
a datatable or right-clicking on the datatable and choose 'Add | Key'
command.

The foreign key constraint is created by data relation between two
datatables.

In VS, open the dataset in the designer and double-click a data relation
between two datatables if any. In the 'Relation' dialog box, if the option
of 'Both Relation and Foreign Key constraint' or 'Foreign Key Constraint
Only' in the 'Choose what to create' part is selected, a foreign key
contraint is created.

try to execute the stored procedure myself directly from SQL Server ?

When calling TableAdapter's method to execute a store procedure, we have no
chance to get the value of the parameters passed to the TableAdapter.

I suggest that you use SqlCommand instead and set the CommandType property
of the SqlCommand object to 'StoredProcedure' and set the CommandText
property to the name of the stored procedure. Then you can get the value of
the parameters through the Parameters property of the SqlCommand object.

Hope this helps.
If you have any question, please feel free to let me know.

Sincerely,
Linda Liu
