SELECT A.Name, H.Name as BookedBy
FROM dbo.vwAllLoads A WITH (NOEXPAND)
LEFT JOIN dbo.SystemInfo H
ON (A.BookedByUserID = H.GlobalNetUserID)
WHERE ((A.CustomerID IN (SELECT UCR.CustomerID
FROM dbo.UserCustomerRelations UCR
WHERE UCR.UserID IN
(SELECT UserID FROM #PodUsers)
OR H.GlobalUserID IN
(SELECT UserID FROM #PodUsers)))
Now I filter data using above where clause. How can I accomplish the same using joins or in a better way?
Please help
Assuming your query is something like:
select a.*
from a
where A.CustomerID IN (SELECT UCR.CustomerID
FROM dbo.UserCustomerRelations UCR
WHERE UCR.UserID IN (SELECT UserID FROM #PodUsers) OR
UCR.GlobalNetUserID IN (SELECT UserID FROM #PodUsers)
-----------------------------^ was `H`, I'm assuming is `UCR`
)
Then the following should be an equivalent query using joins:
select distinct a.*
from a join
dbo.UserCustomerRelations ucr
on A.CustomerID = ucr.CustomerID join
#PodUsers pu
on ucr.UserId = pu.UserId or ucr.UserId = ucr.GlobalNetUserID = pu.UserId;
The distinct would be unnecessary if you know that the joins do not produce multiple rows
I guess something like this:
INNER JOIN [dbo].[UserCustomerRelations] UCR
ON A.[CustomerID] = UCR.[CustomerID]
INNER JOIN #PodUsers PU
ON UCR.[CustomerID] = PD.[UserID]
OR H.[GlobalNetUserID] = PD.[UserID]

I am trying to rewrite a query which has a correlated subquery, the idea is to replace it with a CTE and join it later.
I have three tables, tbl_transaction, tbl_beneficiaries and tbl_reg_countries. The current (in short) SQL looks like the following.
SELECT
t.USER_ID,
t.TRANSACTION
FROM tbl_transactions t
JOIN tbl_beneficiaries b ON b.ID = t.USER_ID
WHERE b.COUNTRY NOT IN (
SELECT rc.country
FROM tbl_reg_countries rc
WHERE rc.id = t.USER.ID)
My goal is to query only those transactions for each user where the transaction happens outside of the registered countries. So a user may registered X,Y,Z country but had business with Q. In that case only Q should be returned. How could this be replaced with a CTE/JOIN?
I assume both tbl_beneficiaries.COUNTRY and tbl_reg_countries.COUNTRY are not nullable. You can use a LEFT JOIN with NULL test to detect never matching rows
SELECT
t.USER_ID,
t.TRANSACTION
FROM tbl_transactions t
JOIN tbl_beneficiaries b ON b.ID = t.USER_ID
LEFT JOIN tbl_reg_countries rc ON rc.id = t.USER_ID AND b.COUNTRY = rc.country
WHERE rc.country IS NULL
I would try rewriting query with "with"
Like this:
With a As
(Select
Distinct rc.country
From tbl_reg_countries rc
Inner Join tbl_transactions t on rc.id = t.USER.ID
)
Select
t.USER_ID,
t.TRANSACTION
From tbl_transactions t
Inner Join tbl_beneficiaries b On b.ID = t.USER_ID
Where b.COUNTRY Not In (select * from a)
I am working with sql server through SSMS right now. How can i choose all people with multiple(>2)vacancies?
I am trying something like that, but i dont understand how to make part with "more than 2 vacancies"?
SELECT dbo.applicants.FirstName, dbo.vacancy.Name
FROM dbo.applicants INNER JOIN
dbo.VacancyApplicant ON dbo.applicants.id = dbo.VacancyApplicant.ApplicantId INNER JOIN
dbo.vacancy ON dbo.VacancyApplicant.VacancyId = dbo.vacancy.id WHERE dbo.vacancy.Name='third vacancy'
SELECT dbo.applicants.FirstName, dbo.vacancy.Name
FROM dbo.applicants A INNER JOIN
dbo.VacancyApplicant V ON A.id = V.ApplicantId
WHERE EXIST(
SELECT 1
FROM dbo.applicants INNER JOIN
dbo.VacancyApplicant ON dbo.applicants.id =
dbo.VacancyApplicant.ApplicantId INNER JOIN
dbo.vacancy ON dbo.VacancyApplicant.VacancyId = dbo.vacancy.id
WHERE A.id=dbo.applicants.id
GROUP BY dbo.applicants.id,dbo.vacancy.id
HAVING COUNT(1)>2
)
Group By and Having are you basic answer. Below is a simple solution, might not be ideal, but can give you the idea.
I am finding target "applicants" ids in subquery, that uses GROUP BY and HAVING then outer query joins to that to output FirstName and LastName of applicant
SELECT dbo.applicants.FirstName, dbo.applicants.LastName FROM
dbo.applicants a INNER JOIN
(
SELECT dbo.applicants.id
FROM dbo.applicants INNER JOIN
dbo.VacancyApplicant ON dbo.applicants.id = dbo.VacancyApplicant.ApplicantId INNER JOIN
dbo.vacancy ON dbo.VacancyApplicant.VacancyId = dbo.vacancy.id AND dbo.vacancy.Name='third vacancy'
GROUP BY dbo.applications.id
HAVING COUNT(dbo.vacancy.id) > 2
) targetIds ON a.id = targetIds.id
"more than 2 vacancies"?
Your question only mentions vacancies but your query is filtering for a particular name. I assume you really want more than two of that name.
If I understand correctly, you want aggregation:
SELECT a.FirstName, a.Name
FROM dbo.applicants a INNER JOIN
dbo.VacancyApplicant va
ON a.id = va.ApplicantId INNER JOIN
dbo.vacancy v
ON va.VacancyId = v.id
WHERE v.Name = 'third vacancy'
GROUP BY a.FirstName, v.Name
HAVING COUNT(*) > 2;
Note the use of table aliases. They make the query easier to write and to read.
WITH TempCTE AS (
SELECT DISTINCT ap.FirstName
,vc.Name
,COUNT (va.VacancyId) OVER (PARTITION BY ap.id) AS NoOfVacancies
FROM dbo.applicants ap
JOIN dbo.VacancyApplicant va
ON ap.id = va.ApplicantId
JOIN dbo.vacancy vc
ON va.VacancyId = vc.id
)
SELECT FirstName,[Name], NoOfVacancies FROM TempCTE
WHERE NoOfVacancies > 2
I am trying to create one single query that will give me a distinct count for both the ActivityID and the CommentID. My query in MS Access looks like this:
SELECT
tbl_Category.Category, Count(tbl_Activity.ActivityID) AS CountOfActivityID,
Count(tbl_Comments.CommentID) AS CountOfCommentID
FROM tbl_Category LEFT JOIN
(tbl_Activity LEFT JOIN tbl_Comments ON
tbl_Activity.ActivityID = tbl_Comments.ActivityID) ON
tbl_Category.CategoryID = tbl_Activity.CategoryID
WHERE
(((tbl_Activity.UnitID)=5) AND ((tbl_Comments.PeriodID)=1))
GROUP BY
tbl_Category.Category;
I know the answer must somehow include SELECT DISTINCT but am not able to get it to work. Do I need to create multiple subqueries?
This is really painful in MS Access. I think the following does what you want to do:
SELECT ac.Category, ac.num_activities, aco.num_comments
FROM (SELECT ca.category, COUNT(*) as num_activities
FROM (SELECT DISTINCT c.Category, a.ActivityID
FROM (tbl_Category as c INNER JOIN
tbl_Activity as a
ON c.CategoryID = a.CategoryID
) INNER JOIN
tbl_Comments as co
ON a.ActivityID = co.ActivityID
WHERE a.UnitID = 5 AND co.PeriodID = 1
) as caa
GROUP BY ca.category
) as ca LEFT JOIN
(SELECT c.Category, COUNT(*) as num_comments
FROM (SELECT DISTINCT c.Category, co.CommentId
FROM (tbl_Category as c INNER JOIN
tbl_Activity as a
ON c.CategoryID = a.CategoryID
) INNER JOIN
tbl_Comments as co
ON a.ActivityID = co.ActivityID
WHERE a.UnitID = 5 AND co.PeriodID = 1
) as aco
GROUP BY c.Category
) as aco
ON aco.CommentId = ac.CommentId
Note that your LEFT JOINs are superfluous because the WHERE clause turns them into INNER JOINs. This adjusts the logic for that purpose. The filtering is also very tricky, because it uses both tables, requiring that both subqueries have both JOINs.
You can use DISTINCT:
SELECT
tbl_Category.Category, Count(DISTINCT tbl_Activity.ActivityID) AS CountOfActivityID,
Count(DISTINCT tbl_Comments.CommentID) AS CountOfCommentID
FROM tbl_Category LEFT JOIN
(tbl_Activity LEFT JOIN tbl_Comments ON
tbl_Activity.ActivityID = tbl_Comments.ActivityID) ON
tbl_Category.CategoryID = tbl_Activity.CategoryID
WHERE
(((tbl_Activity.UnitID)=5) AND ((tbl_Comments.PeriodID)=1))
GROUP BY
tbl_Category.Category;
I'm currently working with database, but I've got stuck with a select query.
However, I'm not database expert.
The query should return the data from a table that has two relationships of many to many.
This is my tables Diagram that would shows the concept of my question
The Select Query should View three columns, which are VidTbl.Name, ActorTbl.Name and SubTitelTbl.name.
So, I've read and search in the Internet and I've given tries
First try
SELECT
VidTbl.NAME AS Video_Titel_Name,
ActorTbl.NAME AS Actor_Name
FROM ActorInVid
INNER JOIN VidTbl
ON VidTbl.Id = ActorInVid.FKVidId
INNER JOIN ActorTbl
ON ActorTbl.Id = ActorInVid.FKActorId
UNION all
SELECT
VidTbl.NAME AS Video_Titel_Name,
SubTitelTbl.NAME AS SubTitel_Langu
FROM SubTitelInVid
INNER JOIN VidTbl
ON VidTbl.Id = SubTitelInVid.FKVidId
INNER JOIN SubTitelTbl
ON SubTitelTbl.Id = SubTitelInVid.FKSTId
The Result I've got, it was wrong
Then I tried another way to solve this problem, but again I've got another error
second try
SELECT Temp1.*
From (SELECT VidTbl.Id AS Video_Id,
VidTbl.NAME AS Video_Titel_Name,
ActorTbl.NAME AS Actor_Name
FROM ActorInVid
INNER JOIN VidTbl
ON VidTbl.Id = ActorInVid.FKVidId
INNER JOIN ActorTbl
ON ActorTbl.Id = ActorInVid.FKActorId) AS Temp1
SELECT Temp2.*
FROM (SELECT VidTbl.Id AS Video_Id,
SubTitelTbl.NAME AS SubTitel_Langu
FROM SubTitelInVid
INNER JOIN VidTbl
ON VidTbl.Id = SubTitelInVid.FKVidId
INNER JOIN SubTitelTbl
ON SubTitelTbl.Id = SubTitelInVid.FKSTId) AS Temp2
SELECT *
FROM VidTbl
INNER JOIN Temp1
on Temp1.Video_Id = VidTbl.Id
INNER JOIN Temp2
on Temp2.Video_Id = VidTbl.Id
The error, I've got in the last select that was wrong
Thanks a lot for your help any ways
I wish that my question is clear and useful
Thanks again.
You are close. This should work...
SELECT
VidTbl.Name,
ActorTbl.Name,
SubTitelTbl.name
FROM VidTbl
INNER JOIN ActorInVid ON VidTbl.Id = ActorInVid.FKVidId
INNER JOIN ActorTbl ON ActorTbl.Id = ActorInVid.FKActorId
INNER JOIN SubTitelInVid ON VidTbl.Id = SubTitelInVid.FKVidId
INNER JOIN SubTitelTbl ON SubTitelTbl.Id = SubTitelInVid.FKSTId
SELECT DISTINCT vt.Name, at.Name, st.Name
FROM VidTbl vt
JOIN ActionInVid aiv ON aiv.VidId = vt.Id
JOIN SubtitleInVid siv ON siv.VidId = vt.Id
JOIN ActorTbl at ON at.Id = aiv.ActorId
JOIN SubTitleTbl st ON st.Id = siv.STId
Can anyone please tell me how to write a delete statement for the following query:
SELECT a.UserID, b.UserEmailAddress
FROM tblUserProgramme AS a LEFT OUTER JOIN
tblUser AS b ON b.UserID = a.UserID LEFT OUTER JOIN
tblWorkGroup AS c ON c.WorkGroupID = b.WorkGroupID
WHERE(a.ProgrammeID = 59) AND (a.UserID NOT IN
(SELECT UserID FROM tblUser AS a WHERE (WorkGroupID IN
(SELECT WorkGroupID FROM tblWorkGroup WHERE
(WorkGroupName LIKE '%Insight%') OR (WorkGroupName LIKE '%Other%')))))
AND (b.UserEmailAddress NOT IN
(SELECT email FROM tmpUsers))
ORDER BY b.UserEmailAddress
SERVER is SQL Server 2005
Query would be
Delete from
(
SELECT a.UserID, b.UserEmailAddress
FROM tblUserProgramme AS a LEFT OUTER JOIN
tblUser AS b ON b.UserID = a.UserID LEFT OUTER JOIN
tblWorkGroup AS c ON c.WorkGroupID = b.WorkGroupID
WHERE(a.ProgrammeID = 59) AND (a.UserID NOT IN
(SELECT UserID FROM tblUser AS a WHERE (WorkGroupID IN
(SELECT WorkGroupID FROM tblWorkGroup WHERE (WorkGroupName LIKE
'%Insight%') OR (WorkGroupName LIKE '%Other%'))))) AND (b.UserEmailAddress NOT IN
(SELECT email FROM tmpUsers))
ORDER BY b.UserEmailAddress
) a
Syntax is DB specific..
For most of tha databases this should work , if you want to delete from tblUserProgramme
DELETE A
FROM tblUserProgramme AS a
.....
In general, in SQL Server, you can delete all records which match a given SQL query as follows, provided your SELECT only returns columns from a single table:
DELETE x
FROM
(
-- Any query which returns data from a single table, that you wish to delete
) x;
Or, using a CTE:
;WITH x as
(
-- Any query which returns data from a single table, that you wish to delete
)
DELETE x;
Thank you all for your quick answers:) There were a quite a few answers right, but had to pick the first one:)
As Joe G Joseph has mentioned,
this is what i did
DELETE a
from dbo.tblUserProgramme a
LEFT OUTER JOIN tblUser b ON b.UserID = a.UserID
LEFT OUTER JOIN tblWorkGroup c ON c.WorkGroupID = b.WorkGroupID
where a.ProgrammeID = 59 AND
a.UserID NOT IN (SELECT UserID FROM tblUser a WHERE a.WorkGroupID IN
(SELECT WorkGroupID FROM tblWorkGroup
WHERE WorkGroupName like '%Insight%' OR WorkGroupName like '%Other%'))
AND b.UserEmailAddress NOT IN(SELECT email FROM tmpUsers)
