+  Hide errors which show view underlying table information. 
+  There are currently two mechanisms at work that handle errors for views,
+  this one and a more general mechanism based on an Internal_error_handler,
+  see Show_create_error_handler. The latter handles errors encountered during

+  handles SELECT from views. The two methods should not clash.
