I have the Standard Edition.  I was running select statements before and all was working fine but now for some reason it does not working.....

For example if I try to get the resultset or return all rows from the graphical interface (rigth click----> Open Table...) I do not have problems I receive the resultset...

In fact with any query, for example if I run Select 1 or Select getdate().......,I got the same thing.
