This is the report I need - but I want to only select records after a given date - so that I'm not getting the entire history everytime. Any ideas on how to do this - I've tried Where gg.timemodified >= '2014-09-25' -- I'm wondering if it is a UNIX Time thing - any help would be GREATLY Appreciated
SELECT u.firstname AS 'First' , u.lastname AS 'Last', CONCAT(u.firstname , ' ' , u.lastname) AS 'Display Name',
c.fullname AS 'Course',
cc.name AS 'Category',
CASE
WHEN gi.itemtype = 'course'
THEN CONCAT(c.fullname, ' - Total')
ELSE gi.itemname
END AS 'Item Name',
ROUND(gg.finalgrade,2) AS Grade,
FROM_UNIXTIME(gg.timecreated) AS TIME
FROM mdl_course AS c
JOIN mdl_context AS ctx ON c.id = ctx.instanceid
JOIN mdl_role_assignments AS ra ON ra.contextid = ctx.id
JOIN mdl_user AS u ON u.id = ra.userid
JOIN mdl_grade_grades AS gg ON gg.userid = u.id
JOIN mdl_grade_items AS gi ON gi.id = gg.itemid
JOIN mdl_course_categories AS cc ON cc.id = c.category
WHERE gi.courseid = c.id AND gg.timecreated is not NULL
ORDER BY lastname
