delete command using DataAdapter in c#
I am trying to insert/update/delete a field from my sql server table using dataadapter in c# windows application.
Here insert and update are happening,but 'delete' is not working
I will show my delete part :
public int UpdateAllUserDetails(DataSet dsUsers)
private SqlConnection connection;
private SqlCommand command;
private SqlDataAdapter dataAdapter;
connection = new SqlConnection(ConfigurationManager.AppSettings.Get("conString"));
dataAdapter = new SqlDataAdapter(command);
dataAdapter.DeleteCommand = new SqlCommand("DELETE FROM UserDetails WHERE vUserName=@vUserName", connection);
dataAdapter.DeleteCommand.Parameters.Add("@vUserName", SqlDbType.VarChar, 50, "vUserName");
int ret = dataAdapter.Update(dsUsers);
can somebody say what is missing here?
