Putting that statement in the where line, gets me no results found. There should be 5 records coming back.

Thanks anyway.

>I don't understand why stu.enrollment_status <> 'INACTIVE' should be part of the JOIN. Rather, it should be in the WHERE clause:

>   LEFT JOIN addresses AS adr ;
>   ON stu.student_id = adr.student_id AND ;
>   stu.school_year = adr.school_year ;
>   WHERE stu.enrollment_status <> 'INACTIVE' ;
