It's just shorthand so you don't have to use the full table name all the time:

PHP Code:


			
useractivation AS ua

That simply means that you are allowed to use the shorthand "ua" instead of "useractivation". So for instance:

PHP Code:


			
AND ua.emailchange = 0

is the same as:

PHP Code:


			
AND useractivation.emailchange = 0
