npertuset Posted June 17, 2011 Share Posted June 17, 2011 I'm having an SQL query issue. I think I need to self join, but I can't exactly figure out what to do. I have a table that keeps track of student exams. ID is the unique ID, studentno is the student ID number, moduleid is the course id, sitting is each time they took the exam (they can take an exam for a course as many times as they want) and grade is their grade. I just need to select the studentno, moduleid, sitting and grade for each student/course, but I only want to display the final sitting (See this for example: http://pastebin.com/X1ELnFa2) Link to comment https://forums.phpfreaks.com/topic/239609-db-query/ Share on other sites More sharing options...
