How do I join these two databases?
This table contains all users on the system. each one has a unique "UserID"
This table contains only those users who have completed a test
If they complete a test, the field "YourType" IS NOT NULL
All rows contain the field "UserID"
Both tables have "UserID" in common
I'm looking to output those users who have completed the test, but I need their Email and LastName which is in the Users table
