The DbCommandBuilder.DataAdapter has not been initialized.The DataAdapter.SelectCommand property has not been initialized.The
DataAdapter.SelectCommand.Connection property has not been initialized.Dynamic SQL generation is not supported against multiple
base tables.Dynamic SQL generation is not supported against a SelectCommand that contains duplicate columns.Dynamic SQL generation
for the DeleteCommand is not supported against a SelectCommand that does not return any key column information.
After the SQL statement is first generated, the application must explicitly call the DbCommandBuilder.RefreshSchema if it
changes the ULDataAdapter.SelectCommand in any way. Otherwise, the GetDeleteCommand method still uses information from the
previous statement, which might not be correct. The SQL statements are first generated when the application calls either the
DbDataAdapter.Update(System.Data.DataSet) or the GetDeleteCommand method.
