I am trying to select my data but the where-clause says that "dp.active" is an INVALID Identifier. This is probably because the table dp is in the subquery. I have tried to give it an alias name and some other things I found while browsing stackoverflow, but I cant seem to find a solution. Any idea?
This is Oracle PL/SQL.
Put the check for active = 1 in the subquery as shown below.
select * from iiasa_inventory.inv_device d
join iiasa_inventory.inv_type ty on d.type_id = ty.id
join iiasa_inventory.inv_category c on ty.category_id = c.id
join iiasa_inventory.inv_device_2_barcode b on b.device_id = d.id
join iiasa_inventory.inv_barcodes bc on b.barcode_id = bc.id
join iiasa_inventory.inv_status s on d.status = s.id
join iiasa_inventory.inv_brand br on ty.brand_id = br.id
left join iiasa_inventory.inv_supplier su on su.id = d.supplier_id
left join iiasa_inventory.inv_supplier sup on sup.id = d.maintenance_with
left join (select distinct device_id from iiasa_inventory.inv_device_2_persons_cc where active = 1) dp on dp.device_id = d.id
That is because you are not selecting active column in dp.
select * from iiasa_inventory.inv_device d
join iiasa_inventory.inv_type ty on d.type_id = ty.id
join iiasa_inventory.inv_category c on ty.category_id = c.id
join iiasa_inventory.inv_device_2_barcode b on b.device_id = d.id
join iiasa_inventory.inv_barcodes bc on b.barcode_id = bc.id
join iiasa_inventory.inv_status s on d.status = s.id
join iiasa_inventory.inv_brand br on ty.brand_id = br.id
left join iiasa_inventory.inv_supplier su on su.id = d.supplier_id
left join iiasa_inventory.inv_supplier sup on sup.id = d.maintenance_with
left join (select distinct device_id,active from iiasa_inventory.inv_device_2_persons_cc) dp on dp.device_id = d.id
where dp.active = 1
OR you can just filter from the subquery itself. Like:
left join (select distinct device_id
from iiasa_inventory.inv_device_2_persons_cc
where active=1) dp on dp.device_id = d.id

Correct result table
Step1) Start count with the driver table i.e. the one you have alias as 'A'. Check the count if you get 3. Continue.
Repeat step 1 with each new join and see where your count blows up to 12. That is your troubling join. Comment it out if possible and continue with joins. If you cannot do successive joins then find best solution to bring count back down to 3.
If your sure of your where clause great; else start without it too. If count is more than 3. Pop it back in.

The commented parts are the code im trying to include to select the field, but it is giving me errors..
The problem is that you use aliases in your where clause of select sub-query. Aliases cannot be referenced on the same level in the query. You should use full qualified names and the sub-query should look something like that:
(select TOP 1 DTPROGENTR from CMPENL0 C (NOLOCK) where X.NRPEDICOMP = CMPENL0.NRPEDICOMP AND X.NRITEMPECO = CMPENL0.NRITEMPECO) AS DTPROGENTR
If your sql-server supports common table expressions you can try that:
;WITH cte AS
(
SELECT ROW_NUMBER() OVER(PARTITION BY NRPEDICOMP, NRITEMPECO ORDER BY NRPEDICOMP) row_num
,DTPROGENTR
,NRPEDICOMP
,NRITEMPECO

I have four tables and I need to find the average of each score for a particular id. I do not need the ENTIRE Column average, but the average of each record with the same id in each table.
I have tried this:
SELECT DISTINCT M.system_id, S.name, SUM(A.Score + WAL.score + F.score + WIN.score) / 4
AS avgScore
FROM dbo.T3_MovementSystemJoin AS M
INNER JOIN dbo.T3_systems AS S ON M.system_id = S.id

Thanks for your help!
No Sum needed (and no grouping too)

If you don't want NULL values to become zeros and included in the average:

WHERE (M.movement_id = #movement_id)
GROUP BY M.System_id, S.name
I'm getting this error: Cannot use an aggregate or a subquery in an expression used for the group by list of a GROUP BY clause.
I searched on internet, but i don't know how to apply the correction in my case. I found different types of query only.
I'm trying to get a Count result in a field (line 5), but when I add the Count query i'm getting this error.
I'm using SQL SERVER 2008 R2.
When I remove the Count from SELECT and GROUP BY the query run correctly.

I integrated the num_aditivo subquery in a LEFT JOIN.
I have a rather complex query that pretty much mimics a test query I have below:
SELECT C.*
FROM Customer C
INNER JOIN CustDetail CD ON C.CustomerId = CD.CustomerId
INNER JOIN Address A ON CD.DetailID = A.DetailID
INNER JOIN Group G ON C.CustomerId = G.CustomerId --Join only when C.code = 1
INNER JOIN GroupDetail D ON G.GroupId = D.DetailId --Join only when C.code = 1
WHERE G.Active = 1 AND --Only when C.code = 1
D.code = '1' AND --Only when C.code = 1
C.Id = #customerId
I'd like to do INNER JOINs on Group G and GroupDetail D (and ofcourse not have them in the WHERE conditions based on the table column C.code = 1
I replaced the INNER JOINs with LEFT OUTER JOINs for both the join conditions, but the result set is not what was expected
How do I conditionally do the JOIN
SELECT C.*
FROM Customer C
INNER JOIN CustDetail CD ON C.CustomerId = CD.CustomerId
INNER JOIN Address A ON CD.DetailID = A.DetailID
LEFT OUTER JOIN Group G ON C.CustomerId = G.CustomerId
LEFT OUTER JOIN GroupDetail D ON G.GroupId = D.DetailId
WHERE ((G.Active = 1 AND C.code = 1) OR G.Active IS NULL) AND
((D.code = '1' AND C.code = 1) OR D.code IS NULL) AND
C.Id = #customerId
I'm guessing you didn't include the IS NULL checks before so you never got to see rows where C.code <> 1 ?
You should check for NULL on a field that will never be null. This is almost always 'id', but it's not clear that you have a G.id or a D.id.
I'm guessing what you want is just a tighter ON clause, and a compound condition.
SELECT C.*
FROM Customer C
INNER JOIN CustDetail CD ON C.CustomerId = CD.CustomerId
INNER JOIN Address A ON CD.DetailID = A.DetailID
-- the next two joins happen only when c.code=1
-- their columns will be null when there is no match.
LEFT JOIN Group G ON C.CustomerId = G.CustomerId AND C.Code = 1
LEFT JOIN GroupDetail D ON G.GroupId = D.DetailId AND C.Code = 1
WHERE C.Id = #customerId AND --always check this
-- this condition is true if code is null or code isn't 1,
((C.code IS NULL or C.code <> 1)
-- or (if the code is 1), it is true if g.active and d.code
OR (G.Active = 1 AND D.code = '1'))
This will do a semi-join only when code is 1.
SELECT C.*
FROM Customer C
INNER JOIN CustDetail CD
ON C.CustomerId = CD.CustomerId
INNER JOIN Address A
ON CD.DetailID = A.DetailID
WHERE
C.Id = #customerId AND
(c.code != 1 OR
EXISTS(
SELECT NULL
FROM Group G
JOIN GroupDetail D ON G.GroupId = D.DetailId
WHERE
C.CustomerId = G.CustomerId AND
G.Active = 1 AND
D.code = '1'
))
