Sql server query to join two tables to get desired result set - sql

I have two table Customer-items and Available-locations i need to get the location where all items in customer-items are available.
Customer-items
ItemID ItemName
1 item1
2 item2
3 item3
Available-locations
LocationID ItemID AvailableForPickup
20 1 1
20 2 1
20 3 0
21 1 1
21 2 1
21 3 1
on simple inner join e.g
SELECT * FROM Customer-items
INNER JOIN Available-locations
ON Customer-items.ItemID = Available-locations.ItemsID AND AvailableForPicup = 1
this will exclude item 3 from Available-locations for LocationID 20 but return other two items for locationID 20 and all items for location 21.
i need to get the result set like; to exclude all items for location if any of item is not available.
Available-locations_CustomerItems
LocationID ItemID AvailableForPickup
21 1 1
21 2 1
21 3 1

select * from Customer-items
join Available-locations
on Customer-items.ItemID = Available-locations.ItemsID
where Available-locations.LocationID in
(select LocationID from Available-locations where AvailableForPickup = 1)

Please use the below code. It's working fine with SQL Server 2012.
DECLARE #Customer_Items TABLE (ItemsID int,ItemName VARCHAR(10))
DECLARE #Available_Locations TABLE (LocationID int,ItemsID int,AvailableForPickup int)
INSERT INTO #Customer_Items (ItemsID,ItemName)
VALUES
(1,'item1'),
(2,'item2'),
(3,'item3')
INSERT #Available_Locations
(LocationID,ItemsID, AvailableForPickup)
VALUES
(20,1,1),
(20,2,1),
(20,3,0),
(21,1,1),
(21,2,1),
(21,3,1)
SELECT LocationID,al.ItemsID,AvailableForPickup FROM #Customer_Items ci
INNER JOIN #Available_Locations al
ON ci.ItemsID = al.ItemsID AND al.AvailableForPickup = 1
WHERE al.LocationID NOT IN (SELECT al2.LocationID FROM #Available_Locations al2 WHERE al2.AvailableForPickup =0)

You could use NOT IN in following:
SELECT l.*
FROM [Customer-items] AS i
INNER JOIN [Available-locations] AS l ON i.ItemID = l.ItemID
WHERE l.LocationID NOT IN (SELECT LocationID FROM [Available-locations] WHERE AvailableForPicup = 0)
Note that - is not available in tables names. You have to use brackets [] on table names like [customer-items]. Also use alias names on tables to make It more readable.
OUTPUT
LocationId ItemId AvailableForPickup
21 1 1
21 2 1
21 3 1

SELECT B.ITEMID
,B.LOCATIONID
,B.AVAILABLEFORPICKUP
FROM #A A
RIGHT JOIN #B B ON A.ITEMID = B.ITEMID
WHERE B.AVAILABLEFORPICKUP= 1

SELECT * FROM Customer-items
INNER JOIN Available-locations
ON Customer-items.ItemID = Available-locations.ItemsID AND locationId
NOT IN (select locationID FROM Available-locations WHERE AvailableForPicup = 0)

SQL split one column into two columns based on values and use columns

Table: ProductionOrder
Id Ordernumber Lotsize
1 Order1 50
2 Order 2 75
3 WO-order1 1
4 WO-order2 1
Table: history
Id ProductionOrderID Completed
1 3 1
2 3 1
3 4 1
4 4 1
Table: ProductionOrderDetail
ID ProductionOrderID ProductionOrderDetailDefID Content
1 1 16 50
2 1 17 7-1-2018
3 2 16 75
4 2 17 7-6-2018
Start of my code:
Select p.ID, p.OrderNumber,
Case productionOrderDetailDefID
Where(Select pd1.productionOrderDetailDefID where ProductionOrderDetialDefID = 16) then min(pd1.content)
from ProductionOrder p
Left join History h1 on p.id = h1.productionOrderID
Left Join ProductionOrderDetail pd1 on p.ID = ProductionOrderID
The result in trying to get is
Id Ordernumber Lotsize Productionorder Completed
1 Order1 50 WO-order1 2
2 Order 2 75 WO-order2 2
Any help would be appreciated.
Try this
SELECT ordernumber,lotsize,Ordernumber,count(Ordernumberid)
FROM productionorder inner join history on productionorder.id = history.Ordernumberid
GROUP BY Ordernumber;
A bit of weird joins going on here. You should add this to a SQL fiddle so that we can see our work easier.
A link to SQL fiddle: http://sqlfiddle.com/
Here is my first attempt
SELECT
po.id
, po.ordernumber
, po.lotsize
, po2.productionorder
, SUM(h.completed)
FROM productionorder as po
INNER JOIN history as h
ON h.id = po.id
INNER JOIN prodcuctionorder as po2
ON po2.ordernumberid = h.ordernumberid
WHERE po.id NOT EXISTS IN ( SELECT ordernumberid FROM history )
GROUP BY
po.id
, po.ordernumber
, po.lotzise
, po2.productionorder
How far does that get you?

How to select rows from a group using a condition

I have a table which contains data in this format.
ProductID ShipId
11 1
11 2
11 3
22 1
22 2
33 1
33 2
Now I want only the distinct product ids where ship id 3 is not associated.
Output should be
22,33 only.
I have used this query but it throws error.
Select distinct productid from X_product_ship group by productid having shipid <> 3
Please help.
Use a subquery in the where clause to exclude the products that has a shipid of three.
select distinct P1.ProductID
from dbo.X_product_ship as P1
where P1.ProductID not in (
select P2.ProductID
from dbo.X_product_ship as P2
where P2.ShipId = 3
)
SQL Fiddle
Or you could get creative in the having clause using a case statement.
select P.ProductID
from dbo.X_product_ship as P
group by P.ProductID
having max(case when P.ShipId = 3 then 1 else 0 end) = 0

SQL Join with multiple row condition in second table

I have a question on SQL join which involve multiple condition in second joined table. Below is the table details
Table 1
pId status keyVal
---- ------- ------
100 1 45
101 1 46
Table 2
pId mode modeVal
100 2 5
100 3 6
101 2 7
101 3 8
I have above two tables and I am trying to join based on below condition to get pId's
pId's which has keyVal = 45 and status = 1 joined with table2 which has mode = 2 and modeVal 5 and mode =3 and modeVal = 6
the result I am expecting is to return pid = 100
Can you please help me with a join query ?
One way is to use GROUP BY with HAVING to count that the number of rows found is 2, of which 2 are matching the condition;
WITH cte AS (SELECT DISTINCT * FROM Table2)
SELECT t1."pId"
FROM Table1 t1 JOIN cte t2 ON t1."pId" = t2."pId"
WHERE t1."status" = 1 AND t1."keyVal" = 45
GROUP BY t1."pId"
HAVING SUM(
CASE WHEN t2."mode"=2 AND t2."modeVal"=5 OR t2."mode"=3 AND t2."modeVal"=6
THEN 1 END) = 2 AND COUNT(*)=2
If the values in t2 are already distinct, you can just remove the cte and select directly from Table2.
An SQLfiddle to test with.
SELECT columns
FROM table1 a, table2 B
WHERE a.pid = B.pid
AND a.keyval = 45
AND a.status = 1
AND (
(B.mode = 2 AND B.modeval = 5)
OR
(B.mode = 3 AND B.modeval = 6)
)
Below query should work for you perfectly
select distinct table1.pid FROM table1 JOIN table2
on table1.pid = table2.pid
WHERE table2.modeValue IN (5,6) AND table2.mode IN (2,3) AND table1.keyVal=45 and table1.status=1;

how to prevent duplicates with inner join query (Postgres)

I am trying to understand how to create a query to filter out some results based on an inner join.
Consider the following data:
formulation_batch
-----
id project_id name
1 1 F1.1
2 1 F1.2
3 1 F1.3
4 1 F1.all
formulation_batch_component
-----
id formulation_batch_id component_id
1 1 1
2 2 2
3 3 3
4 4 1
5 4 2
6 4 3
7 4 4
I would like to select all formulation_batch records with a project_id of 1, and has a formulation_batch_component with a component_id of 1 or 2. So I run the following query:
SELECT formulation_batch.*
FROM formulation_batch
INNER JOIN formulation_batch_component
ON formulation_batch.id = formulation_batch_component.formulation_batch_id
WHERE formulation_batch.project_id = 1
AND ((formulation_batch_component.component_id = 2
OR formulation_batch_component.component_id = 1 ))
However, this returns a duplicate entry:
1;"F1.1"
2;"F1.2"
4;"F1.all"
4;"F1.all"
Is there a way to modify this query so that I only get back the unique formulation_batch records which match the criteria?
EG:
1;"F1.1"
2;"F1.2"
4;"F1.all"
Thanks for your time!
In this case it is possible to apply the distinct before the join possibly making it more performant:
select fb.*
from
formulation_batch fb
inner join
(
select distinct formulationbatch_id
from formulation_batch_component
where component_id in (1, 2)
) fbc on fb.id = fbc.formulationbatch_id
where fb.project_id = 1
Notice how to use alias for the table names to make the query clearer. Also then in operator is very handy. The use of double quotes with those identifiers is not necessary.
One way would be to use distinct:
SELECT distinct "formulation_batch".*
FROM "formulation_batch"
INNER JOIN "formulation_batch_component"
ON "formulation_batch"."id" = "formulation_batch_component"."formulationBatch_id"
WHERE "formulation_batch"."project_id" = 1
AND (("formulation_batch_component"."component_id" = 2
OR "formulation_batch_component"."component_id" = 1 ))
I know the question asks how to prevent duplicates with inner join but could use an IN clause in the predicate.
SELECT "formulation_batch".*
FROM "formulation_batch" fb
ON "formulation_batch"."id" = "formulation_batch_component"."formulationBatch_id"
WHERE "formulation_batch"."project_id" = 1
AND fb.id IN (SELECT "formulation_batch"."id"
FROM formulation_batch_component
WHERE (("formulation_batch_component"."component_id" = 2
OR "formulation_batch_component"."component_id" = 1 ))

Avoid repeatation of rows for every instance when joined with a table

Hi i have 3 tables and i am trying to join them to get a desire table. I have tried group by and temp tables options to get the desired table but no help. I want to avoid duplicates for every instance of a value in one table from another table.
Table 1 Customer Table:
CstId CstDetails CstType
---------- --------------- ------------
1 address 1 1
2 address 2 1
3 address 3 1
4 address 4 2
5 address 5 2
Table 2 Customer Relationship:
CstId CstGroupId
---------- ----------------
1 4 (this is same as CustomerId)
2 5 (this is same as CustomerId)
3 4 (this is same as CustomerId)
Table 3 Customer Notes:
CstId NotesId NoteTxt
----------- --------- ---------
1 1 note11
1 2 note12
1 3 note13
3 1 note31
4 1 note41
4 2 note42
4 3 note43
4 4 note44
4 5 note45
Now i want the result to be in the below format
Table result:
(NoteId) (Notetxt) (NoteId) (Notetxt)
CstId CstDetails CstGroupId CstNoteId CstNote CstGroupNoteId CstGroupNote
1 address1 4 1 note11 1 note41
1 address1 4 2 note12 2 note42
1 address1 4 3 note13 3 note43
1 address1 4 null null 4 note44
1 address1 4 null null 5 note45
But i am getting CstGroupNote repeated for all the CstNote, which i am trying to avoid.
Is there a way i could achieve this result?
Below is the code i use:
select c.cstid, c.cstdetails, cn.cstnotesid, cn.cstnotetxt
insert into temp1
from customer c
left outer join customernotes cn
on c.cstid = cn.cstid
where c.customertypeid = 1
select cr.cstid, cr.cstgroupid, cn.cstgroupnoteid, cn.cstnotetxt
insert into temp2
from customerrelationship cr
left outer join customernotes cn
on cr.cstgroupid = cn.customerid
select t1.cstid, t1.cstdetails, t1.cstnotesid, t1.cstnotetxt, t2.cstgroupnoteid, t2.cstnotetext
from temp1 t1
left outer join t2
on t1.cstid = t2.cstid
Try:
select CstId,
max(CstDetails) CstDetails,
max(CstGroupId) CstGroupId,
max(CstNoteId) CstNoteId,
max(CstNote) CstNote,
max(CstGroupNoteId) CstGroupNoteId,
max(CstGroupNote) CstGroupNote
from
(select c.CstId,
c.CstDetails,
0 CstGroupId,
n.NotesId CmbNotesId,
n.NotesId CstNoteId,
n.NoteTxt CstNote,
0 CstGroupNoteId,
'' CstGroupNote
from customer c
left outer join customernotes n on c.cstid = n.cstid
where c.customertypeid = 1
union all
select c.CstId,
c.CstDetails,
r.CstGroupId,
n.NotesId CmbNotesId,
0 CstNoteId,
'' CstNote,
n.NotesId CstGroupNoteId,
n.NoteTxt CstGroupNote
from customer c
left outer join customerrelationship r on c.cstid = r.cstid
left outer join customernotes n on r.CstGroupId = n.cstid
where c.customertypeid = 1) u
group by CstId, CmbNotesId
Use a derived table and an outer join
The trick there is the
and cn.cstnotesid = cG.cstnotesid
to link those two on one row
select c.cstid, c.cstdetails, cn.cstnotesid, cn.cstnotetxt
,cG.CstGroupId, cG.cstnotesid, cG.cstnotetxt
from customer c
join customernotes cn
on cn.cstid = c.cstid
outer join (select c.cstid, c.CstGroupId, cn.cstnotesid, cn.cstnotetxt
from customer c
join customernotes cn
on cn.cstid = c.CstGroupId) as cG
on c.cstid = cG.cstid
and cn.cstnotesid = cG.cstnotesid
order by c.cstid, cn.cstnotesid, cG.cstnotesid
