Custom block for display of scorm interactions with tree button

Question

I can't insert the values of the third interaction of a scorm . I see the values of the second interaction reported. Where am I wrong? thank you

this is the code
SELECT scc.userid AS User, sct.name AS Name, scc.scoid AS SCORM_ID, sct.module AS Module, scc.value AS Touch_1, sct.value AS touch_2, sct.value AS Touch_3
FROM

(SELECT u.id AS userid, st.scoid AS scoid, st.value AS value

FROM prefix_course AS c

LEFT JOIN prefix_scorm AS sc ON sc.course=c.id

LEFT JOIN prefix_scorm_scoes_track AS st ON st.scormid=sc.id

LEFT JOIN prefix_user AS u ON u.id=st.userid

WHERE st.element='cmi.interactions_0.time') AS scc

LEFT JOIN

(SELECT c.fullname Course, sc.name AS module, st.scoid AS scoid, u.id AS userid, u.firstname name, st.attempt as Attempt, st.value AS value

FROM prefix_course AS c

LEFT JOIN prefix_scorm AS sc ON sc.course=c.id

LEFT JOIN prefix_scorm_scoes_track AS st ON st.scormid=sc.id

LEFT JOIN prefix_user AS u ON u.id=st.userid

WHERE st.element='cmi.interactions_1.time') AS sct 





ON sct.scoid=scc.scoid

AND sct.userid=scc.userid

ORDER BY scc.userid

this is the wrong result

You haven't got a 3rd element in the SQL :)

Rather than using sub queries, I would probably use a GROUP BY if you want to put the values in columns.

SELECT u.id AS userid, u.firstname,
    c.id AS courseid, c.fullname AS coursename,
    s.id AS scormid, s.name AS scormname,
    MAX(CASE WHEN sst.element = 'cmi.interactions_0.time' THEN sst.value ELSE '' END) AS time0,
    MAX(CASE WHEN sst.element = 'cmi.interactions_1.time' THEN sst.value ELSE '' END) AS time1,
    MAX(CASE WHEN sst.element = 'cmi.interactions_2.time' THEN sst.value ELSE '' END) AS time2
FROM mdl_course c
JOIN mdl_scorm s ON s.course = c.id
JOIN mdl_scorm_scoes_track sst ON sst.scormid = s.id
    AND sst.element IN ('cmi.interactions_0.time', 'cmi.interactions_1.time', 'cmi.interactions_2.time')
JOIN mdl_user u ON u.id = sst.userid
GROUP BY u.id, u.firstname, c.id, c.fullname, s.id, s.name
