I used the above information to get me to the following:
SELECT DISTINCT Username, FirstName, LastName, TabName
FROM useraccount, UserAccountDashboardAssign, UserAccount_Page
WHERE UserAccount.UserID = UserAccountDashboardAssign.UserID
AND UserAccount.UserID = UserAccount_Page.UserID
ORDER BY UserAccount.UserName
This is the query that I'm currently working on, but gets me some good information currently.
