The viewer defaults to the Columns, which is a repetition of what's already in the Object Explorer. How do I change the Tab Order so it defaults to Data?
You can use Options - Explorer - Objects to set the tab order.
Once there - check the 'Display details' checkbox. Then use the up\down arrows to rearrange the tabs as shown below. You will need to select the database type (on the top of that screen) as well. In my example, I selected DB2... Hope this helps.
