I have the following.
In my dataset I have the table listed and there is a primary key.

using System.Data.SqlClient;

Datasetname dt = new Datasetname ();
command.CommandText = "Select * from table1"
adapter.SelectCommand = command;
adapter.Fill (dt, "table1");
SqlCommandBuilder commandb = new SqlCommandBuilder(adapter);
adapter.UpdateCommand = commandb.GetUpdateCommand();

I get the error:
Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information

I have no idea why.

Can you generate a CREATE script for table1 from SQL Server?  It seems that the SqlCommandBuilder is not able to determine what the primary key is.
