The error you get is because just having the SELECT privilege on the view/tables should not be enough to view the data. Please grant the ’SHOW VIEW’ privilege on the view inorder to view the data from the View which would rule out the error you get.
I think the original request is still valid. Since that error message does not affect the execution of the query, but only the EXPLAIN, SQLyog should treat it as a warning message, perhaps in the EXPLAIN output window, rather than a pop-up error message.
