After running a query in the Editor there is no window that shows the results
After executing code in the Editor, no window displays showing the results. All that can be seen is the Editor, where code is typed.
RESOLUTION #1: Right click in Editor and select Desktop and make sure "Data Grid" or "Script Output" is checked. Data Grid would be for executing as statement (F9) and Script Output would be for executing as script (F5).
RESOLUTION #2: Make sure that the results window (Data Grid or Script Output) is not unpinned. If it is unpinned, a tab should be visible at the bottom of the Editor. Hovering over that tab will make the results window appear. If this is the case, clicking the pin in the top right corner of the results window will pin the window, so it stays visible.
RESOLUTION #3: Right click in the Editor and select Desktop | Restore Default Desktop.
