Data adapter configureation error

Hi everybody. I got a db in sql server and it has 6 tables inside it .One of
the table that i want to create a datagrid using visual studio .net 2003 is
called matches. Unfortunetly when i try Right-click on the DataAdapter and choose Generate DataSet
i get the following errors.The table matches exist in sql server 2000 with data inside it but
i do not know why i get these error. I be happy if some one help me fix this problem.Thanks

Errors 1 and 2 indicate that you don't have any primary key specified for the table. Establish a primary key and try again.

thank u for u reply. Do u mean should i declare a column in sql server as a primary key? since i am new to sql server. could u guide me where i can declare a column as primary key?thanks

Yes, you need to define a column in your table as the primary key. This can be done with transact SQL (CREATE TABLE... script) or with the SQL enterprise manager.
