SQL 所有未完成课程的用户的特别报告

Question

海刚！

我非常接近找到一份报告，我可以运行临时查找所有未注册课程的用户。我确实有一份针对未完成课程的已注册人员的报告，但此搜索未找到甚至未注册的给定学生。

当前代码为

SELECT u.lastname, u.firstname , u.email , c.fullname, 

DATE_FORMAT(FROM_UNIXTIME(cc.timecompleted),'%m/%d/%Y %T') AS 'Completed'

FROM 
prefix_role_assignments AS ra
JOIN prefix_context AS context ON context.id = ra.contextid 

AND
context.contextlevel = 50 JOIN prefix_course AS c ON c.id = context.instanceid

AND
 c.fullname LIKE "SAMPLE_COURSE_NAME" 
JOIN prefix_user AS u ON u.id = ra.userid 
JOIN prefix_course_completions AS cc ON cc.course = c.id 
AND cc.userid = u.id

ORDER BY
cc.timecompleted,
u.lastname,
u.firstname

有什么想法吗？？

Answer 1

这将列出所有未注册课程的用户 - 不过可能会很大。

将xxx替换为课程ID

SELECT u.id AS userid, u.firstname, u.lastname, u.email
FROM mdl_user u
WHERE u.deleted = 0
AND u.suspended = 0
AND NOT EXISTS (
    SELECT ue.userid
    FROM mdl_user_enrolments ue
    JOIN mdl_enrol e ON e.id = ue.enrolid AND e.courseid = xxx
    WHERE ue.userid = u.id
)

Answer 2

更新...我发现使用“mdl_”在 moodle 框架内不起作用，但您可以将其替换为“prefix_”并且它有效！太感谢了！我永远不会想到这个设置。

SELECT u.id AS userid, u.firstname, u.lastname, u.email
FROM prefix_user u
WHERE u.deleted = 0
AND u.suspended = 0
and firstname not like "Guest user"

AND NOT EXISTS (
    SELECT ue.userid
    FROM prefix_user_enrolments ue
    JOIN prefix_enrol e ON e.id = ue.enrolid AND e.courseid = XXX
    WHERE ue.userid = u.id
)

ORDER BY
Lastname,
Firstname
