i want to get some details not in ratings table with user name and i made a cross join query. but it shows me syntax error
SELECT applications.reference as "User id", applications.id
FROM applications
cross join ratings where (applications.id) NOT IN ( SELECT ratings.application_id FROM ratings )
INNER JOIN ratings ON users.id=ratings.user_id
error shows
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'INNER JOIN ratings ON users.id=ratings.user_id LIMIT 0, 25' at line 2
i want to get user details in applications where not in ratings table with user name in users table. how can i fix this?
I think you need such a query :
SELECT a.reference as "User id", a.id
FROM applications a
CROSS JOIN ratings r
INNER JOIN users u ON u.id = r.user_id
WHERE a.id != r.application_id;
SELECT applications.reference as "User id", applications.id
FROM applications
INNER JOIN ratings ON users.id=ratings.user_id
cross join ratings where (applications.id) NOT IN ( SELECT ratings.application_id FROM ratings )

There are three tables in the database users, organization_entries and user_invoices and I am trying to Join these three tables and my query is somewhat like this
select users.id , sum(user_invoices.due_amount) , organization_entries.id, organization_entries.createdAt from users INNER JOIN user_invoices ON users.id = user_invoices.customer_id INNER JOIN on users.id = organization_entries.user_id GROUP BY users.id ORDER BY organization_entries.createdAt;
But again and again, I am getting this error -
ERROR 1064 (42000): 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 'on users.id = organization_entries.user_id GROUP BY users.id ORDER BY organiza' at line 1
I am not able to understand where I am doing things wrong.
Update the query as follows, you are missing table in second inner join
select users.id , sum(user_invoices.due_amount) , organization_entries.id,
organization_entries.createdAt
from users INNER JOIN user_invoices ON users.id = user_invoices.customer_id
INNER JOIN organization_entries ON users.id = organization_entries.user_id
GROUP BY users.id ORDER BY organization_entries.createdAt ;
I have one problem with my SELECT query in my blog page.
I want comment count of each blog when comment status=1.
I am apply following query..
SELECT CONCAT(u.first_name," ",u.last_name) name, r.*,
IF(c.status=1,COUNT(c.id)) as comment
FROM users u
RIGHT JOIN resources r ON u.id = r.created_by
LEFT JOIN comments c ON r.id = c.resource_id
WHERE r.type = 1
AND r.status=1
GROUP BY r.id
ORDER BY r.created_date DESC
LIMIT 0,5
but it giving SYNTAX ERROR..
Error: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your
SQL syntax; check the manual that corresponds to your MariaDB server version for the right
syntax to use near ') as comment FROM users u RIGHT JOIN resources r ON u.id = r.created_by
LEFT JOI' at line 1
Please tell me where I am wrong.
Thanks
If statement contains three expressions. First, the expression, second the value returned if condition is true and third if condition is false so you are missing the third expression.
Try the below code
SELECT CONCAT(u.first_name," ",u.last_name) name,r.*,IF(c.status=1,COUNT(c.id), 0) as comment
FROM users u RIGHT JOIN resources r ON u.id = r.created_by
LEFT JOIN comments c ON r.id = c.resource_id
WHERE r.type = 1
AND r.status=1
GROUP BY r.id
ORDER BY r.created_date DESC
LIMIT 0,5
Select concat(u.first_name," ",u.last_name) name,r.*,
case when c.status=1 then COUNT(c.id) end as comment
FROM users u RIGHT JOIN resources r ON u.id = r.created_by
LEFT JOIN comments c ON r.id = c.resource_id
WHERE r.type = 1
AND r.status=1
GROUP BY r.id
ORDER BY r.created_date DESC
LIMIT 0,5

if function requires 3 parameters to be passed to it. IF(expression ,expr_true, expr_false) is how it should be used.
Have a look at https://www.w3resource.com/mysql/control-flow-functions/if-function.php
I've got the following SQL query and I'm trying to implement pagination, so I first want to get the COUNT of the result:
The normal query (works fine)
SELECT DISTINCT c.*, p1.*, username FROM candidate c
LEFT JOIN note p1 ON (c.candID = p1.candidateID)
LEFT JOIN user ON p1.userID = user.id
LEFT OUTER JOIN note p2 ON
(c.candID = p2.candidateID AND (p1.noteID < p2.noteID))
WHERE p2.candidateID IS NULL ORDER BY c.firstname ASC
I've tried the following, but it throws an error and I'm not sure what correct syntax to use:
Attempting to count the results (doesn't work)
SELECT COUNT(DISTINCT c.*, p1.*, username) FROM candidate c
LEFT JOIN note p1 ON (c.candID = p1.candidateID)
LEFT JOIN user ON p1.userID = user.id
LEFT OUTER JOIN note p2 ON
(c.candID = p2.candidateID AND (p1.noteID < p2.noteID))
WHERE p2.candidateID IS NULL ORDER BY c.firstname ASC
The error:
Syntax error or access violation: 1064 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 ', p1., username) FROM candidate c LEFT ' at line 1
One option is to use a subquery:
SELECT COUNT(*)
FROM (
SELECT DISTINCT c.*, p1.*, username FROM candidate c
LEFT JOIN note p1 ON (c.candID = p1.candidateID)
LEFT JOIN user ON p1.userID = user.id
LEFT OUTER JOIN note p2 ON
(c.candID = p2.candidateID AND (p1.noteID < p2.noteID))
WHERE p2.candidateID IS NULL
) t
Depending on your data, you may be able to do this without the subquery, but you cannot use multiple columns with the count aggregate -- that's what is causing your error.
I have 2 tables :
albums (idalbum, idauthor, idcompositor, idfeat)
people (id, firstname, last name)
My current Query :
SELECT * FROM albums where idalbum=:id
INNER JOIN people ON albums.idauthor = people.id
INNER JOIN people ON albums.idcompositor = people.id
INNER JOIN people ON albums.idfeat = people.id
What I want to do with my query :
[Album], [Author[First Name, Last Name]], [Compositor[First Name, Last Name]], [Feat[First Name, Last Name]]
My problem:
I have an error : SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax;
You need to correct your query where clause should be used after your join statements and also you are not using proper table names, according to structure shown in question you can write your query as
SELECT * FROM albums a
INNER JOIN people p ON a.idauthor = p.id
INNER JOIN people p1 ON a.idcompositor = p1.id
INNER JOIN people p2 ON a.idfeat = p2.id
where a.idalbum=:id
Basically I'm just unsure as to why this query is failing to execute:
(SELECT replies.reply_post, replies.reply_content, replies.reply_date AS d, members.username
FROM (replies) AS a
INNER JOIN members ON replies.reply_by = members.id)
UNION
(SELECT posts.post_id, posts.post_title, posts.post_date AS d, members.username
FROM (posts) as b
WHERE posts.post_set = 0
INNER JOIN members ON posts.post_by = members.id)
ORDER BY d DESC LIMIT 5
I'm getting this error:
#1064 - 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 'a INNER JOIN members ON replies.re' at line 2
All I'm trying to do is select the 5 most recent rows (dates) from these two tables. I've tried Join, union etc and I've seen numerous queries where people have put another query after the FROM statement and that just makes no logical sense to me as to how that works?
Am I safe to say that you can join the same table from two different but joined queries? Or am I taking completely the wrong approach, because frankly I can't seem see how this query is failing despite reading the error message.
(The two queries on there own work fine)
I think there is syntax error in your query at below part :
FROM (posts) as b
WHERE posts.post_set = 0
INNER JOIN members ON posts.post_by = members.id)
Inner join should come first before where condition. Also your join conditions are wrong. You need to apply conditions like
INNER JOIN members ON a.reply_by = members.id)
INNER JOIN members ON b.post_by = members.id)
So your query should be like this
(SELECT a.reply_post, a.reply_content, a.reply_date AS d, members.username
FROM (replies) AS a
INNER JOIN members ON a.reply_by = members.id)
UNION
(SELECT b.post_id, b.post_title, b.post_date AS d, members.username
FROM (posts) as b
INNER JOIN members ON b.post_by = members.id
WHERE b.post_set = 0)
ORDER BY d DESC LIMIT 5
Try this:
(SELECT a.reply_post, a.reply_content, a.reply_date AS d, members.username
FROM replies AS a
INNER JOIN members ON a.reply_by = members.id)
UNION
(SELECT b.post_id, b.post_title, b.post_date AS d, members.username
FROM posts as b
INNER JOIN members ON b.post_by = members.id
WHERE b.post_set = 0) /* Use where condition after matching Id's using ON */
ORDER BY d DESC LIMIT 5
