I want to list all activities and resources in Moodle Course.. It should have details of ID, type, name and course id with name...
Someone would have created an adhoc query..
Can you someone help here please. Thanks
This will give you the activities per course but not the activity name
SELECT c.id AS courseid, c.fullname AS coursename,
cm.instance AS activityid, m.name AS activitytype
FROM mdl_course_modules cm
JOIN mdl_course c ON c.id = cm.course
JOIN mdl_modules m ON m.id = cm.module
ORDER BY c.fullname, m.name
For the activity name you will need to add the table for each activity in your site. So you will need to add to this list if you add new activities.
SELECT c.id AS courseid, c.fullname AS coursename,
cm.instance AS activityid, m.name AS activitytype,
activity.activityname
FROM mdl_course_modules cm
JOIN mdl_course c ON c.id = cm.course
JOIN mdl_modules m ON m.id = cm.module
LEFT JOIN (
SELECT a.id, a.name AS activityname, 'scorm' AS activitytype
FROM mdl_scorm a
UNION
SELECT a.id, a.name AS activityname, 'forum' AS activitytype
FROM mdl_forum a
UNION
SELECT a.id, a.name AS activityname, 'label' AS activitytype
FROM mdl_label a
UNION
SELECT a.id, a.name AS activityname, 'url' AS activitytype
FROM mdl_url a
....
) activity ON activity.id = cm.instance AND activity.activitytype = m.name
ORDER BY c.fullname, m.name

I have a problem I've been working on. I've broken it down to a couple of steps below. I have trouble combining all the queries together to solve the following:
Find members who have spent over $1000 in departments that have
brought in more than $10000 total ordered by the members' id.
Schema:
departments(id, name)
products (id, name, price)
members(id, name, number, email, city, street_name, street_address)
sales(id, department_id, product_id, member_id, transaction_date
Step 1)
I found the departments that have brought in more than 10,000$
select s.department_id
from sales s join products p on
s.product_id = p.id
group by s.department_id
having sum(price) > '10000'
Step 2) I found the members and the departments that they shop in
select *
from members m
join sales s
on m.id = s.member_id
join departments d
on d.id = s.department_id
Step 3) I combined 1 and 2 to find members taht shop in departments that have brought in more than 10,000
select *
from members m
join sales s
on m.id = s.member_id
join departments d
on d.id = s.department_id
where s.department_id in
(select s.department_id
from sales s join products p on
s.product_id = p.id
group by s.department_id
having sum(price) > '10000')
Step 4) I found members and their id, email, total_spending > 1,000$
select m.id, m.name, m.email, sum(price) as total_spending
from members m join sales s on
m.id = s.member_id
join products p on
p.id = s.product_id
group by m.id
having sum(price) > '1000'
Step 5)
All of the steps work individually but when I put them together in my attempt:
select m.id, m.name, m.email, sum(price) as total_spending
from members m join sales s on
m.id = s.member_id
join products p on
p.id = s.product_id
where m.id in (select distinct m.id
from members m
join sales s
on m.id = s.member_id
join departments d
on d.id = s.department_id
where s.department_id in
(select s.department_id
from sales s join products p on
s.product_id = p.id
group by s.department_id
having sum(price) > '10000'))
group by m.id
having sum(price) > '1000'
The output is wrong. (This is on CodeWars) If someone could point me in the right direction that would be really great! Thank you.
Try to group by member_id and department_id:
select s.member_id,s.department_id,sum(p.price) as total_spending
from members m
join sales s on m.id = s.member_id
join products p on p.id = s.product_id
where s.department_id in (
select s.department_id
from sales s
join products p on s.product_id = p.id
group by s.department_id
having sum(p.price) > 10000 -- the departments which brought in more than $10000 total
)
group by s.member_id,s.department_id
having sum(p.price) > 1000 -- who have spent over $1000 in one department
And if you need you will able to calc how much spent each of members:
select member_id,sum(total_spending) total
from
(
-- the first query is here
) q
group by member_id
I have a query like this:
select c.id, c.name, c.website, c.longdescription, c.description, c.email,
(SELECT jsonb_agg(ev) FROM
(SELECT ev.title, ev.description, ev.longdescription,
(SELECT jsonb_agg(ed) FROM
(SELECT ed.startdate, ed.enddate, ed.id WHERE ed.id notnull)ed) as dates, ev.id WHERE ev.id notnull) ev) as events,
(SELECT jsonb_agg(ca) FROM (SELECT ct.zip, ca.id, ca.street1, ca.street2, ca.addresstype_id, ST_Y(ca.geopoint::geometry) as latitude, ST_X(ca.geopoint::geometry) as longitude
WHERE ca.id notnull)ca) as addresses
FROM companies c
LEFT JOIN events ev ON ev.company_id = c.id
LEFT JOIN companyaddresses ca ON ca.company_id = c.id
LEFT JOIN cities ct ON ct.id = ca.city_id
LEFT JOIN eventdates ed ON ed.event_id = ev.id
GROUP by c.id
I am getting the error "ERROR: subquery uses ungrouped column "ev.title" from
outer query Position: 125".
Can't figure out how to group it correctly for the subqueries. Any suggestions?
Give this a try:
SELECT c.id, c.name, c.website, c.longdescription, c.description, c.email,
(SELECT jsonb_agg(ev) FROM
(SELECT even.title, even.description, even.longdescription,
(SELECT jsonb_agg(ed) FROM
(SELECT eventdates.startdate, eventdates.enddate, eventdates.id FROM eventdates WHERE eventdates.event_id = even.id)ed) as dates,
even.id FROM events even WHERE even.company_id = c.id) ev) as events,
jsonb_agg((SELECT ca FROM (SELECT ct.zip, ca.id, ca.street1, ca.street2, ca.addresstype_id, ST_Y(ca.geopoint::geometry) as latitude, ST_X(ca.geopoint::geometry) as longitude WHERE ca.id notnull)ca)) as addresses
FROM companies c
LEFT JOIN companyaddresses ca ON ca.company_id = c.id
LEFT JOIN cities ct ON ct.id = ca.city_id
Group by c.id
this query is not returning correct latest_enrolment date. whenever i enrol a user in course, it doesnot updates enrolment date in database.. can anyone help?
SELECT TRIM(c.id) course_id,TRIM(c.fullname) course_fullname,FROM_UNIXTIME(u.timecreated) as registration ,FROM_UNIXTIME( ra.timemodified ) latest_enrolment_date,COUNT( * ) AS enrol_count
FROM mdl_user u
INNER JOIN mdl_role_assignments ra ON ra.userid = u.id
INNER JOIN mdl_context ct ON ct.id = ra.contextid
INNER JOIN mdl_course c ON c.id = ct.instanceid
INNER JOIN mdl_role r ON r.id = ra.roleid
INNER JOIN mdl_course_categories cc ON cc.id = c.category
WHERE r.id =5 GROUP BY c.id
Something like this
SELECT MAX(ue.timecreated) AS latest_enrolment_date
FROM mdl_enrol e
JOIN mdl_user_enrolments ue ON ue.enrolid = e.id
WHERE e.courseid = xx
I need a query to return records if all conditions Match.
Example:
Lets say I have a User “John” (UserID: '37') that belongs to groups 'A','B','C' (GroupID: '47', '48', '166')
And I type
Select person, group
from persons p inner join groups g
on p.id = g.id
where p.id = '37'
and g.id in ('47','166')
The query should return No Record because not all conditions match, Group 'C' was not part of the query.
How can I do this?
This has to be a dup but I cannot find it
Select p.id
from persons p inner join groups g
on p.id = g.UserID
where p.id = '37'
and g.GroupID in ('47','166')
group by person
having count(*) = 2
--The subquery did what I was after
SELECT p.id, g.id
FROM persons p inner join groups g
on p.id = g.Userid
where g.Userid =
(select Userid from groups gs
where p.id = gs.Userid
And gs.id in (47,166)
group by g.Userid
having count(distinct gs.id) = 3)
