can someone help me.
I need to change my sql query to a querybuilder. I don't know how to use select inside a innerJoin.
Here my sql query:
SELECT
user.id,
analytic_youtube_demographic.age_group,
analytic_youtube_demographic.percentage
FROM
user
INNER JOIN user_youtube ON user_youtube.id = user.id
INNER JOIN analytic ON analytic.id = user_youtube.analytic_id
INNER JOIN analytic_youtube_demographic ON analytic_youtube_demographic.analytic_id = analytic.id
INNER JOIN
(
SELECT analytic_youtube_demographic.id as id, MAX(analytic_youtube_demographic.percentage) max
from user
INNER JOIN user_youtube ON user_youtube.id = user.id
INNER JOIN analytic ON analytic.id = user_youtube.analytic_id
INNER JOIN analytic_youtube_demographic ON analytic_youtube_demographic.analytic_id = analytic.id
GROUP BY user.id
) AS T ON analytic_youtube_demographic.percentage = T.max
WHERE analytic_youtube_demographic.age_group IN ('18-24')
Thanks a lot for your help.

I'm trying to get a list of ALL user roles for each user through the nopcommerce database. i just need the Customer.Id, Customer.Username, Customer.Email and Customer.Role (some have multiple roles)
This is all jacked up.
SELECT Customer.Id, Customer.Username, Customer.Email, CustomerRole.Name
FROM ((Customer
INNER JOIN CustomerRole ON CustomerRole.Id = Customer.Id)
INNER JOIN Customer_CustomerRole_Mapping ON Customer_CustomerRole_Mapping.CustomerRole_Id = CustomerRole.Id)
Any help is greatly appreciated!
I think you need a LEFT OTUER JOIN because in your DB can be user without role; in this case you can use this:
SELECT DISTINCT CUST.Id, CUST.Username, CUST.Email, CR.Id, CR.Name,
CCRM.CustomerRole_Id ,
FROM CUSTOMER CUST
LEFT OUTER JOIN Customer_CustomerRole_Mapping CCRM
ON CUST.ID = CCRM.Customer_Id
LEFT OUTER JOIN CustomerRole CR
ON CCRM.CustomerRole_Id = CR.Id
Also, you can have only one row per user with a column with his roles, like this:
SELECT DISTINCT CUST.Id, CUST.Username, CUST.Email,
Roles = STUFF((
SELECT ',' + CAST(CR1.Name as varchar(4000))
FROM CustomerRole CR1
LEFT OUTER JOIN Customer_CustomerRole_Mapping CCRM1
ON CCRM1.CustomerRole_Id = CR1.Id
LEFT OUTER JOIN CUSTOMER CUST1
ON CUST1.ID = CCRM1.Customer_Id
WHERE CUST1.Id = CUST.Id
FOR XML PATH('')
), 1, 1, '')
FROM CUSTOMER CUST
LEFT OUTER JOIN Customer_CustomerRole_Mapping CCRM
ON CUST.ID = CCRM.Customer_Id
LEFT OUTER JOIN CustomerRole CR
ON CCRM.CustomerRole_Id = CR.Id
Depending of your using, last query can be a little bit slow if you have a lot of customers.
I have an issue with the IN instruction for a field...maybe you can see better than me what's happening.
The issue is on the waves parameter.
I got this in my database it's a configuration field...and this field contain a json
{
"typeId":"10,57",
"codeVague":"ITM1702A,ITMTEST"
}
This request inside sql return results:
SELECT v.id,v.`vague_code`, v.`date_fin_ultime`,m.*
FROM Vague v
INNER JOIN Enquete e ON e.`vague_id` = v.`id`
INNER JOIN Mission m ON m.id = e.`mission_id`
INNER JOIN Contrat c ON c.id = m.`contrat_id`
INNER JOIN `User` u ON u.`enqueteur_id` = e.`enqueteur_id`
INNER JOIN `PointDeVente` p ON p.id = e.`pdv_id`
WHERE v.`vague_code` IN ('ITM1702A','ITMTEST')
AND type_id IN (10,57)
But when I try to do the same from my symfony controller...I got an empty result
$sql="SELECT v.id,v.codeVague, v.date_fin_ultime,c.distance,p.adresse1,p.code_postal,p.ville,m
FROM McInvestigatorBundle:Vague v
INNER JOIN McInvestigatorBundle:Enquete e WITH e.vague_id = v.id
INNER JOIN McInvestigatorBundle:Mission m WITH m.id = e.mission_id
INNER JOIN McInvestigatorBundle:Contrat c WITH c.id = m.contrat
INNER JOIN McInvestigatorBundle:User u WITH u.enqueteur_id = e.enqueteur_id
INNER JOIN McInvestigatorBundle:PointDeVente p WITH p.id = e.pdv_id
WHERE v.codeVague IN (:waves)
AND e.type_id IN (:type_id)
AND m.enqueteur_id=:enq_id
ORDER BY m.date_rea_prev ASC";
$results= $em->createQuery($sql)->setParameters([
'waves' => $waves,
'type_id' => $type_id,
'enq_id' => $enq_id,
])->getResult();
The strange thing is that I got no issue with type_id, it works fine.
But, the waves field it's not the same story....
In fact, it works only if I have only one value in the json
"codeVague":"ITM1702A" is working
"codeVague":"ITM1702A,ITMTEST" is not working.
I already tried those strings in $waves.
"ITM1702A,ITMTEST" and "'ITM1702A','ITMTEST'" and "'ITM1702A,ITMTEST'"
Thanks you for your help !
EDIT: Problem solved, thanks Veve.
I am trying to update a field in a table from another table using INNER JOIN. Here is the code:
UPDATE TestResults
INNER JOIN Distractors
ON TestResults.DistractorID = Distractors.ID
SET TestResults.DistractorValue = Distractors.DistractorValue
This does not work I don't know why! Any idea? When I run the query I get the following error
There was an error parsing the query. [ Token line number = 2,Token line offset = 1,Token in error = INNER ]
Not all databases support join syntax with update. And when they do, the syntax differs. Here is a way to do your query without an explicit join using standard SQL:
UPDATE TestResults
set DistractorValue = (select max(d.DistractorValue)
from Distractors d
where TestResults.DistractorValue = d.DistractorValue
)
where exists (select 1
from Distractors d
where TestResults.DistractorValue = d.DistractorValue
);
The max() is only needed if there could be more than one matching row.
The where is only needed if the join is intended to do filtering as well as matching.
UPDATE TestResults
SET TestResults.DistractorValue = Distractors.DistractorValue
FROM TestResults
INNER JOIN Distractors
ON TestResults.DistractorID = Distractors.ID
You use the Updated table in the Inner join clause
ex:
UPDATE TestResults
SET TestResults.DistractorValue = Distractors.DistractorValue
FROM TestResults INNER JOIN Distractors
ON TestResults.DistractorID = Distractors.ID
I am working on an asp.net application "social networking site".in this i am working on the following tables:-
Friends(ID,User_ID,Friend_ID)
Users(User_ID,User_Name,Full_Name,DOB,Gender)
User_Detail(ID,User_ID,Image,Father_Name,Mother_Name,Location,JobProfile)
Wall(Wall_ID,Wall_Content,TimeAgo,User_ID)
Wall_Comments(Comment_ID,Wall_ID,Comments,Comment_Date,User_ID)
I want to select all records of Tables- Wall and Wall_Comments where User_ID=5 and all friends of User_ID=5
I have done following Sql Query:
SELECT DISTINCT TOP (30) wall.wall_content,
wall.wall_id,
wall.user_id,
wall.timeago,
users.user_name,
users.full_name,
users.user_id AS UID,
wall_comments.comments,
wall_comments.comment_id,
CONVERT(NVARCHAR(1000), user_detail.image, 0) AS Image
FROM friends
INNER JOIN users
ON friends.user_id = users.user_id
INNER JOIN wall
ON users.user_id = wall.user_id
INNER JOIN user_detail
ON users.user_id = user_detail.user_id
left outer join wall_comments
ON wall.wall_id = wall_comments.wall_id
WHERE ( users.user_id IN (SELECT friend_id
FROM friends AS Friends_1
WHERE ( user_id = 5 )) )
UNION
SELECT wall.wall_content,
wall.wall_id,
wall.user_id,
wall.timeago,
users.user_name,
users.full_name,
users.user_id AS UID,
wall_comments.comments,
wall_comments.comment_id,
CONVERT(NVARCHAR(1000), user_detail.image, 0) AS Image
FROM wall
INNER JOIN users
ON wall.user_id = users.user_id
INNER JOIN user_detail
ON users. user_id = user_detail.user_id
left outer join wall_comments
ON wall.wall_id = wall_comments.wall_id
WHERE ( users.user_id = 5 )
ORDER BY wall.wall_id DESC
But it is showing only one record of table wall and Wall_Comments of user_ID-5 it is not showing his friends Wall and their post.and If their is not any comment on any wall then it is not showing.please Help me someone.
Something like this?
select *
from Friends
inner join Wall_Comments On (Wall_Comments.User_ID = Friends.User_ID or Wall_Comments.User_ID = Friends.Friend_ID)
inner join Users On Users.User_ID = Wall_Comments.User_ID
where Friends.User_ID = 5
In Visual Studio 2010 with ASP.NET 4, I am trying to join several tables together to put the results in a gridview and details view with sqldatasource. In the sqldatasource wizard I have chosen to specify a custom SQL statement or stored procedure and then in the Query Builder to define complex queries such as JOINs, I have tried to generate a SQL statement to join the problem table with speficific columns from other tables. But when I try to test the query I get an error message which says "Cannot call methods on varchar". I am new to sql statements so please can you advise on what is wrong with the statement.
Here is the generated sql statement below
SELECT Problem.ProblemID, Problem.CustomerID, Problem.Summary,
Problem.DateLogged, Problem.DateUpdated, Status.Status, Priority.Priority,
Technician.Name, Technician.Surname, [Skill Group].[Skill Group],
HelpdeskOperator.Name AS Expr1,
HelpdeskOperator.Surname AS Expr2, Problem.NoteID, Problem.ResolutionID
FROM Problem
INNER JOIN Status ON Problem.StatusID = Status.Status.StatusID
INNER JOIN HelpdeskOperator ON
Problem.HelpdeskID = HelpdeskOperator.HelpdeskID AND Status.StatusID = HelpdeskOperator.StatusID
INNER JOIN Priority ON Problem.PriorityID = Priority.PriorityID
INNER JOIN [Skill Group] ON Problem.SkillGroupID = [Skill Group].SkillGroupID
INNER JOIN Technician ON Problem.ProblemID = Technician.ProblemID
AND Status.StatusID = Technician.StatusID AND
Priority.PriorityID = Technician.PriorityID
AND [Skill Group].SkillGroupID = Technician.SkillGroupID
Thank you in advance
Fixed your query:
SELECT p.ProblemID, p.CustomerID, p.Summary, p.DateLogged, p.DateUpdated, s.Status, pr.Priority, t.Name, t.Surname,
sg.* , ho.Name AS Expr1, ho.Surname AS Expr2, p.NoteID, p.ResolutionID
FROM Problem p
INNER JOIN Status s ON p.StatusID = s.StatusID
INNER JOIN HelpdeskOperator ho ON p.HelpdeskID = ho.HelpdeskID AND s.StatusID = ho.StatusID
INNER JOIN Priority pr ON p.PriorityID = pr.PriorityID
INNER JOIN [Skill Group] sg ON p.SkillGroupID = sg.SkillGroupID
INNER JOIN Technician t ON p.ProblemID = t.ProblemID AND s.StatusID = t.StatusID AND pr.PriorityID = t.PriorityID
AND sg.SkillGroupID = t.SkillGroupID
You had duplicate table identifier in your join clause Status.Status.StatusID
I doubt that your Skill Group table contains column [Skill Group] so changed it to return all values from Skill Group
I just think those were the errors, if not I will need more info about your query and table structure.
EDIT:
First it did not return anything for HelpdeskOperator, look at our query:
INNER JOIN HelpdeskOperator ho ON p.HelpdeskID = ho.HelpdeskID AND s.StatusID = ho.StatusID
that meanse that here is no such HelpdeskOperator record that is assigned to our problem AND statusid, so either problem id points to noexisting helpdeskoperator or statusid of
this operator is different that problem status id.
next is Skill Group
INNER JOIN [Skill Group] sg ON p.SkillGroupID = sg.SkillGroupID
again our problem point to no existing skill group
then Technican
INNER JOIN Technician t ON p.ProblemID = t.ProblemID AND s.StatusID = t.StatusID AND pr.PriorityID = t.PriorityID
AND sg.SkillGroupID = t.SkillGroupID
here is more work as more checks, technicas must be assigned to our problem with given status and priorityt and be in skill group, BUT our skill group is null? so to check if
there is technican for our problem remove AND sg.SkillGroupID = t.SkillGroupID so you get
INNER JOIN Technician t ON p.ProblemID = t.ProblemID AND s.StatusID = t.StatusID AND pr.PriorityID = t.PriorityID
and see if now we get any technican.
I hope this points you into right direction. You must be sure that there are matching record in every joining table.
