i got 4 tables
table A
code accnt
-------------------
123 xxx
222 yyy
333 zzz
table B
code alloted
-----------------------
123 100
222 200
333 300
table C
code ref project
-------------------------------
333 11-2015 maintenance
table D
code ref item cost
---------------------------------------
333 11-2015 hammer 100
333 11-2015 nail 200
i want to join this table and have and output i like this
code accnt ref alloted
-----------------------------------------
123 xxx 100
222 yyy 200
333 zzz 300
333 maintenance 11-2015
333 hammer 11-2015 100
333 nail 11-2015 200
i use left join for this but i can't get the field A.accnt, C.project & D.item to be combine as one column..thanks in advance
Here is the Solution:
select tableA.code, accnt, '' as ref, alloted from tableA join tableB on tableA.code = tableB.code
Union ALL
select code, project as accnt, ref, ''as alloted from tableC
Union ALL
select code, item as accnt, ref, cost as alloted from tableD
Thanks!
Sounds like you need to JOIN the first 2 tables and UNION in the other 2.
See if this works for you --
SELECT a.code, a.accnt, NULL AS ref, b.alloted
FROM A
LEFT JOIN B ON a.code = b.code
UNION
SELECT c.code, c.project AS accnt, c.ref, NULL AS alloted
UNION
SELECT d.code, d.item AS accnt, d.ref, d.cost as alloted
UNION will take distinct results when combining. If you want ALL results, then use UNION ALL instead.
Here is an explanation that might help you understand the difference between the 2 -- JOIN combines multiple tables by appending columns based on some criteria where UNION combines multiple tables by appending rows. There are MANY tutorials out there that explain JOIN/UNION if you need more information.

I have 2 datasets from 2 different sources but many of the members are the same in both datasets. My select statement is :
Select a.member_id, a.start_date, a.customer_id, a.region_id, b.b_start_date, b.customer_id, b.region_id
from dataset1 a
left join dataset2 b
on a.member_id=b.member_id
I want to somehow pick up all recs in A and recs in B where a.member_id = b.member_id but bring in the fields from A when a.start_date = b.b_start_date or a.start_date > b.b_start_date and bring in the fields from B when b.b_start_date > a.start_date.
Here's a pretty small example:
Dataset A:
member_id
start_date
customer_id
region_id
1111
1/30/2021
123
555
2222
1/30/2021
222
555
3333
1/1/2021
345
678
Dataset B:
member_id
b_start_date
customer_id
region_id
1111
1/1/2022
567
444
2222
1/30/2021
222
555
Result:
member_id
customer_id
region_id
1111
567
444
2222
222
555
3333
345

/* try this */
select a.* from a inner join b using (member_id) where a.start_date >= b.b_start_date
union all
select b.* from a inner join b using (member_id) where b.b_start_date > a.start_date;
I'm trying to do some DB during the lockdown and would appreciate some help, since I have been doing this for 5 hours without luck. Got a PDF from a book and sadly, the solutions part isn't readable.
Here are two tables:
**Table 1 named Laptop**
Laptop ID(PK) Name
1 Lenovo
2 Asus
3 Mac
**Table 2 named Buyers**
Buyer ID(PK) Buyer Name Laptop ID(FK) Country
A Jet Li 1 China
B Hermione 1 UK
C Mercato 2 Spain
The activity requests that I create an
"SQL statement that selects all bags names and their buyer name (so 2 columns only), and to show null values as well" because Mac doesn't have a buyer.
I have been trying JOIN and UNION, but no lock.
SELECT Name from Laptop
UNION
SELECT Buyer name from Buyers;
Thank you very much
You need an OUTER JOIN:
SELECT
l.name,
b.buyer_name
FROM
laptop l
LEFT OUTER JOIN buyers b
ON l.laptop_id = b.bag_id;
Demo:
with laptop as(
select 1 laptop_id, 'Lenevo' name from dual union all
select 2 laptop_id, 'Asus' name from dual union all
select 3 laptop_id, 'Mac' name from dual
),
buyers as(
select 'Jet Li' buyer_name, 1 bag_id from dual union all
select 'Hermione' buyer_name, 1 bag_id from dual union all
select 'Mercato' buyer_name, 2 bag_id from dual
)
SELECT
l.name,
b.buyer_name
FROM
laptop l
LEFT OUTER JOIN buyers b
ON l.laptop_id = b.bag_id;
NAME BUYER_NAME

I have CLAIMMASTER table like this
CLAIMNO
123
456
789
and another related table PROCSTATUS like this
CLAIMNO PROCCODE
123 111
123 222
456 111
456 222
789 222
I want to exclude the records from table1 where proccode in table2 is 111
the result should be
CLAIMNO
789
I have tried almost everything i can but the closest result i get is like this
CLAIMNO PROCCODE
123 222
456 222
789 222
I know this should be easy but i can't figure out the query to do this.
please help.
Here is the query
select a.CLAIMNO,b.PROCCODE from dbo.CLAIMMASTER a left join
dbo.PROCSTATUS b on a.CLAIMNO = b.CLAIMNO
where a.CLAIMNO not in (select b.CLAIMNO where b.PROCCODE in ('111'))
If you only need to select claimno then no need to have join.
select a.CLAIMNO from dbo.CLAIMMASTER a
where a.CLAIMNO not in
(select distinct b.CLAIMNO from dbo.PROCSTATUS b where b.PROCCODE = '111')
Also if you have claimno repeated in the claimmaster table then you need to use distinct in the select clause.
select a.CLAIMNO
from dbo.CLAIMMASTER a
inner join dbo.PROCSTATUS b
on a.CLAIMNO = b.CLAIMNO
where a.CLAIMNO not in
(select CLAIMNO FROM dbo.PROCSTATUS where PROCCODE in ('111'))
I need some help. I need to take the data from these 3 tables and create an output that looks like below. The plan_name_x and pending_tallyx columns are derived to make one line per claim id. Each claim id can be associated to up to 3 plans and I want to show each plan and tally amounts in one record. What is the best way to do this?
Thanks for any ideas. :)
Output result set needed:
claim_id ac_name plan_name_1 pending_tally1 plan_name_2 Pending_tally2 plan_name_3 pending_tally3
-------- ------- ----------- -------------- ----------- -------------- ----------- --------------
1234 abc cooks delux_prime 22 prime_express 23 standard_prime 2
2341 zzz bakers delpux_prime 22 standard_prime 2 NULL NULL
3412 azb pasta's prime_express 23 NULL NULL NULL NULL
SQL Server 2005 table to use for the above result set:
company_claims
claim_id ac_name
1234 abc cooks
2341 zzz bakers
3412 azb pasta's
claim_plans
claim_id plan_id plan_name
1234 101 delux_prime
1234 102 Prime_express
1234 103 standard_prime
2341 101 delux_prime
2341 103 standard_prime
3412 102 Prime_express
Pending_amounts
claim_id plan_id Pending_tally
1234 101 22
1234 102 23
1234 103 2
2341 101 22
2341 103 2
3412 102 23
If you know that 3 is always the max amount of plans then some left joins will work fine:
select c.claim_id, c.ac_name,
cp1.plan_name as plan_name_1, pa1.pending_tally as pending_tally1,
cp2.plan_name as plan_name_2, pa2.pending_tally as pending_tally2,
cp3.plan_name as plan_name_3, pa3.pending_tally as pending_tally3,
from company_claims c
left join claim_plans cp1 on c.claim_id = cp1.claim_id and cp1.planid = 101
left join claim_plans cp2 on c.claim_id = cp2.claim_id and cp2.planid = 102
left join claim_plans cp3 on c.claim_id = cp3.claim_id and cp3.planid = 103
left join pending_amounts pa1 on cp1.claim_id = pa1.claimid and cp1.planid = pa1.plainid
left join pending_amounts pa2 on cp2.claim_id = pa2.claimid and cp2.planid = pa2.plainid
left join pending_amounts pa3 on cp3.claim_id = pa3.claimid and cp3.planid = pa3.plainid
I would first join all your data so that you get the relevant columns: claim_id, ac_name, plan_name, pending tally.
Then I would add transform this to get plan name and plan tally on different rows, with a label tying them together.
Then it should be easy to pivot.
I would tie these together with common table expressions.
Here's the query:
with X as (
select cc.*, cp.plan_name, pa.pending_tally,
rank() over (partition by cc.claim_id order by plan_name) as r
from company_claims cc
join claim_plans cp on cp.claim_id = cc.claim_id
join pending_amounts pa on pa.claim_id = cp.claim_id
and pa.plan_id = cp.plan_id
), P as (
select
X.claim_id,
x.ac_name,
x.plan_name as value,
'plan_name_' + cast(r as varchar(max)) as label
from x
union all
select
X.claim_id,
x.ac_name,
cast(x.pending_tally as varchar(max)) as value,
'pending_tally' + cast(r as varchar(max)) as label
from x
)
select claim_id, ac_name, [plan_name_1], [pending_tally1],[plan_name_2], [pending_tally2],[plan_name_3], [pending_tally3]
from (select * from P) p
pivot (
max(value)
for label in ([plan_name_1], [pending_tally1],[plan_name_2], [pending_tally2],[plan_name_3], [pending_tally3])
) as pvt
order by pvt.claim_id, ac_name
Here's a fiddle showing it in action: http://sqlfiddle.com/#!3/68f62/10
I am very new to this type of complicated joins and summing functions.
I had 2 table queries which have same fields (i.e: ProdID, ProdName, NetQty, Unit)
The 1st one query contains OpStock and the 2nd one contains Purchase.
I want to add this 2 table query to make a single table so that I can able to see current stock.
The data looks like this for 1 st table is:
ProdID ProdName Qty
100 Rose 700
101 Lilly 550
103 Jasmine 600
105 Lavender 400
The data looks like this for 2nd table is:
ProdID ProdName Qty
100 Rose 400
101 Lilly 250
104 Lotus 1000
106 MariGold 400
The final data looks like this for 3rd table is:
ProdID ProdName Qty
100 Rose 1100
101 Lilly 800
103 Jasmine 600
104 Lotus 1000
105 Lavender 400
106 MariGold 400
How can i achieve this one using sql for access2003.
Thanks.
I am very sorry Ciaran,
This is purely access used for vb.net
Here Is my access query1
SELECT sp_OpenIandP_Prod.ProdID,
sp_OpenIandP_Prod.ProdName,
Sum(([sp_OpenIandP_Prod.SumOfNetQty]-[sp_OpenSales_Prod.SumOfNetQty])) AS NetQty,
sp_OpenIandP_Prod.UnitSName
FROM sp_OpenIandP_Prod
INNER JOIN sp_OpenSales_Prod ON sp_OpenIandP_Prod.ProdID=sp_OpenSales_Prod.ProdID
GROUP BY sp_OpenIandP_Prod.ProdID,
sp_OpenIandP_Prod.ProdName,
sp_OpenIandP_Prod.UnitSName;
The 1st query result would be like this:
ProdID ProdName NetQty UnitSName
1 Rose 0 Kgs
2 Lilly 7125 Mts
3 Lotus 12374 Nos
The second query is:
SELECT Products.ProdID, Products.ProdName,
Sum(OPDDetails.NetQty) AS SumOfNetQty, Units.UnitSName
FROM Units
INNER JOIN (Products
INNER JOIN (Brands
INNER JOIN OPDDetails ON Brands.BrID=OPDDetails.BrandID)
ON Products.ProdID=Brands.ProdID)
ON Units.UnitID=Products.UnitID
WHERE (((OPDDetails.PurID)>0)
AND ((OPDDetails.OPDDate)>=[StartDate] And (OPDDetails.OPDDate)<=[EndDate]))
GROUP BY Products.ProdID, Products.ProdName, Units.UnitSName;
and the result set would be like this:
ProdID ProdName SumOfNetQty UnitSName
1 Rose 1800 Kgs
2 Lilly 21000 Mts
I got the above result easily.
But it is not as much easy to get like this:
ProdID ProdName SumOfNetQty UnitSName
1 Rose 1800 Kgs
2 Lilly 28125 Mts
3 Lotus 12374 Nos
That's all. Thanks again.
This is not a vb.net question, however you need to use a UNION
Select ProdId, ProdName, Sum(Qty) As QtySum
From (Select ProdId, ProdName, Qty From TableA
Union All
Select ProdId, ProdName, Qty From TableB) DerrivedView
Group By ProdId, ProdName
You can create a UNION between your 2 queries then group by product:
SELECT ProdID, ProdName, Sum(NetQty) As NetQty, UnitSName
FROM
(
SELECT sp_OpenIandP_Prod.ProdID,
sp_OpenIandP_Prod.ProdName,
Sum(([sp_OpenIandP_Prod.SumOfNetQty]-[sp_OpenSales_Prod.SumOfNetQty])) AS NetQty,
sp_OpenIandP_Prod.UnitSName
FROM sp_OpenIandP_Prod
INNER JOIN sp_OpenSales_Prod ON sp_OpenIandP_Prod.ProdID=sp_OpenSales_Prod.ProdID
GROUP BY sp_OpenIandP_Prod.ProdID,
sp_OpenIandP_Prod.ProdName,
sp_OpenIandP_Prod.UnitSName
UNION ALL
SELECT Products.ProdID, Products.ProdName,
Sum(OPDDetails.NetQty) AS NetQty, Units.UnitSName
FROM Units
INNER JOIN (Products
INNER JOIN (Brands
INNER JOIN OPDDetails ON Brands.BrID=OPDDetails.BrandID)
ON Products.ProdID=Brands.ProdID)
ON Units.UnitID=Products.UnitID
WHERE (((OPDDetails.PurID)>0)
AND ((OPDDetails.OPDDate)>=[StartDate] And (OPDDetails.OPDDate)<=[EndDate]))
GROUP BY Products.ProdID, Products.ProdName, Units.UnitSName
)
GROUP BY ProdID, ProdName, UnitSName
