You alias traning_rating as C but you refer it as c(lowercase), that is the cause of the error. Please try this:
SELECT a.id, b.title, b.identifier,c.rating
FROM mdl_course_modules a
LEFT JOIN mdl_scorm_scoes b
ON a.instance = b.scorm and b.scormtype = ''
LEFT JOIN training_rating c
ON c.training_id = a.id and c.user_id = '1'
WHERE a.module='18'
ORDER BY rating DESC

I have a mysql query and is working totally fine when I run this query in phpmyadmin. The raw sql query is
SELECT IF(COUNT(u.id) > 1
, GROUP_CONCAT(CONCAT(a.amenity_name, '_' ,a.id)), a.amenity_name) as m_concat
, u.id as unit_id
, u.building_id
, (uav.id) as uav_id
, a.*
FROM amenities a
JOIN amenity_values av
ON a.id = av.amenity_id
JOIN units_amenities_values uav
ON av.id = uav.amenity_value_id
JOIN units u ON u.id = uav.unit_id
where a.category_id = 370
AND a.property_id = 82
AND u.building_id = 1265
group
by u.id
order
by u.id asc
But, when I try to run the exact query as raw query in laravel it is throwing error. I am trying to run it as:
$statement = DB::select(DB::raw("SELECT IF(COUNT(u.id) > 1, GROUP_CONCAT(CONCAT(a.amenity_name, '_' ,a.id)), a.amenity_name) as m_concat, u.id as unit_id, u.building_id, (uav.id) as uav_id, a.* FROM amenities a INNER JOIN amenity_values av ON a.id = av.amenity_id INNER JOIN units_amenities_values uav ON av.id = uav.amenity_value_id INNER JOIN units u ON u.id = uav.unit_id where a.category_id = '370' AND a.property_id = '82' AND u.building_id = '1265' group by u.id order by u.id asc"));
While running the exact above statement, it throws following errors:
SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'amenity_db_prod.a.amenity_name' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by (SQL: SELECT IF(COUNT(u.id) > 1, GROUP_CONCAT(CONCAT(a.amenity_name, '_' ,a.id)), a.amenity_name) as m_concat, u.id as unit_id, u.building_id, (uav.id) as uav_id, a.* FROM amenities a INNER JOIN amenity_values av ON a.id = av.amenity_id INNER JOIN units_amenities_values uav ON av.id = uav.amenity_value_id INNER JOIN units u ON u.id = uav.unit_id where a.category_id = '370' AND a.property_id = '82' AND u.building_id = '1265' group by u.id order by u.id asc)
I have three tables A B C and i'm trying to retrieve information from all three.
A has the columnns userid avatar username and B has the column postid, dateshared and C has the column commenter postid datecommented.
I'm trying to run the query
Select C.comment, C.commenter, C.datecommented, B.postid, B.dateshared A.username A.avatar from B Left Join C Left join A on C.postid = B.postid AND A.userid = C.commenter where B.postid IN ('1','2','3') order by C.dateshared desc
but it gives the following error:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'where B.postid IN ('1', '2', '3') order by C.dateshared '
Can anyone point out what I'm doing wrong or suggest how to go about it?
Each LEFT JOIN requires its own ON condition:
SELECT C.comment, C.commenter, C.datecommented, B.postid, B.dateshared, A.username A.avatar
FROM B
LEFT JOIN
C
ON C.postid = B.postid
LEFT JOIN
A
ON A.userid = C.commenter
WHERE B.postid IN ('1','2','3')
ORDER BY
C.dateshared desc
This should work for you, your query had some syntax errors:
Select C.comment,C.commenter,C.datecommented,B.postid,B.dateshared,A.username,A.avatar
from B
Left Join C on C.postid = B.postid
Left join A on A.userid = C.commenter
where B.postid IN ('1','2','3')
order by C.dateshared desc
Here is my database structure
https://docs.google.com/open?id=0B9ExyO6ktYcOenZ1WlBwdlY2R3c
My SQL query looks like that
SELECT
u.fullname,
a.id,
a.content,
a.addDT,
a.`right`,
acr.score,
acr.checkDT
FROM
answers a,
users u
LEFT JOIN `answer_chk_results` acr ON acr.aid = a.id
WHERE
a.qid = 7
AND u.id = a.uid
GROUP BY
a.`right` DESC
Getting error message
[Err] 1054 - Unknown column 'a.id' in 'on clause'
I'm pretty sure that a.id column exists
What am I missing?
you can't mix join syntax with comma delimited table syntax. If you are going to left join, you need to use an inner join for the other two tables.
SELECT
u.fullname,
a.id,
a.content,
a.addDT,
a.`right`,
acr.score,
acr.checkDT
FROM
answers a
INNER JOIN users u ON u.id = a.uid
LEFT JOIN `answer_chk_results` acr ON acr.aid = a.id
WHERE
a.qid = 7
GROUP BY
a.`right` DESC
This might work also, but is not guranteed:
SELECT
u.fullname,
a.id,
a.content,
a.addDT,
a.`right`,
acr.score,
acr.checkDT
FROM
(answers a,
users u)
LEFT JOIN `answer_chk_results` acr ON acr.aid = a.id
WHERE
a.qid = 7
AND u.id = a.uid
GROUP BY
a.`right` DESC
I receive an error that the column ls.amount is in field list when
I run the following query.
Can anyone help me diagnose the problem.
SELECT c.name, ic.keyword, COUNT(ic.keyword), SUM(ls.amount), ls.buyer FROM in_clicks AS ic
INNER JOIN ads AS a ON ic.ad_id = a.id
INNER JOIN ad_groups AS ag ON a.ad_group_id = ag.id
INNER JOIN campaigns AS c ON ag.campaign_id = c.id;
INNER JOIN leads AS l ON (ic.id = l.in_click_id)
INNER JOIN lead_status AS ls ON (l.id = ls.lead_id)
WHERE ic.create_date LIKE '%2011-08-19%' AND ic.location NOT LIKE '%Littleton%' AND discriminator LIKE '%AUTO_POST%'
GROUP BY ic.keyword ORDER BY COUNT(ic.keyword) DESC
The exact error message is:
Error Code: 1054
Unknown column 'ls.amount' in 'field list'
Drop the semicolon (;) on line 4. I suspect that is ending you query before you can define the ls alias.
SELECT c.name,
ic.keyword,
COUNT(ic.keyword),
SUM(ls.amount),
ls.buyer
FROM in_clicks AS ic
INNER JOIN ads AS a
ON ic.ad_id = a.id
INNER JOIN ad_groups AS ag
ON a.ad_group_id = ag.id
INNER JOIN campaigns AS c
ON ag.campaign_id = c.id
INNER JOIN leads AS l
ON ( ic.id = l.in_click_id )
INNER JOIN lead_status AS ls
ON ( l.id = ls.lead_id )
WHERE ic.create_date LIKE '%2011-08-19%'
AND ic.location NOT LIKE '%Littleton%'
AND discriminator LIKE '%AUTO_POST%'
GROUP BY ic.keyword

You can reference labelled fields from subqueries inside outer queries. You could even drop the relabelling and just use "b.id_user".
Probably a comma after c.email was missing.
SELECT a.id, a.name, a.ad, c.name, c.phone, c.email,
(
SELECT b.id_user
FROM price_b b
WHERE b.id = a.id
