I have the following tables
tblMainequipment
asset_id rev equipment_name
123 0 box
123 1 box
124 0 box
125 0 bottle
tblmainswablocation
asset_id rev swab_location
123 0 cover
123 0 base
123 1 cover
123 1 base
123 1 lock
124 0 cover
124 0 base
125 0 tube
125 0 cover
I did like to get the total count of swablocations for the maximum rev for a particular asset_id. For example, the total number of swab location for asset_id 123 rev 0 is 2 but for rev 1 its 3. I have been trying to figure out for the past few hours but cant seem to find a solution. I am pretty bad with joins. The following shows the what i am trying to get,
query
asset_id maxrev #swablocation equipment_name
123 1 3 box
124 0 2 cover
125 0 2 bottle
I use the following sql
SELECT MEQ.*
FROM tblMainEquipment AS MEQ
INNER JOIN (Select asset_id, max(rev) as maxrev
From tblmainequipment GROUP By asset_id) AS groupmeq ON
(MEQ.asset_id = groupmeq.asset_id) AND (MEQ.rev = groupmeq.maxrev)
I am not sure how i can add the #swablocation into my query.
Here is a method that uses correlated subqueries:
select me.*,
(select count(*)
from tblmainswablocation as sl
where sl.asset_id = me.asset_id
) as numSwabs
from tblMainEquipment as me
where me.rev = (select max(me2.rev) from tblMainEquipment as me2 where me2.asset_id = me.asset_id);
The advantage is that the outer query does not require aggregation.
You need a count and a group by
SELECT MEQ.asset_id maxrev, MEQ.maxrev,
count(blmainswablocations.swab_location), MEQ.equipment_name
FROM tblMainEquipment AS MEQ
INNER JOIN (Select asset_id, max(rev) as maxrev
From tblmainequipment GROUP By asset_id) AS groupmeq ON
(MEQ.asset_id = groupmeq.asset_id) AND (MEQ.rev = groupmeq.maxrev)
Inner join blmainswablocations on MEQ.asset_id = blmainswablocations.asset_id
Group by MEQ.asset_id maxrev

How do I select only (all) TS like Sally's where the Transaction ID only occurs once?
Bonus points: How do I select TS like Ted's where the sum of all Is_Corresponding_Transaction = 0 != the sum of Is_Corresponding_Transaction = 1 for a given TS_ID?
I was looking and found a Group by or where not exists, but couldn't figure out how to get that to work
Here's an e.g. of what I tried:
select
Full_Name, amount, a.Posted_Date,a.Payee_Name, a.Memo, Accounts.Account_Name
from AccountTransaction a
left join Accounts on Accounts.Account_Code = a.Account_Code
left join users on a.UserId = users.UserId
where not exists (select 1 from AccountTransaction b where a.Transaction_ID = b.Transaction_ID having count(*)>1)
and a.Pending= 0
ORDER by a.Posted_Date desc
Just to expand on Stu's comment. Here is one option that uses the window function
with cte as (
Select *
,NetSum = sum(Amount) over (partition by Transaction_ID)
,NetCnt = sum(1) over (partition by Transaction_ID)
From YourTable
)
Select *
From cte
Where NetSum<>0
or NetCnt<>2

lets say i have 5 computers and i have allocated 3 computers and 1 is no longer going to be used so i should be remaining with 1 computer so now how do i make sql auto generate this math for me
You need to use aggregation and the join your tables -
SELECT id, asset_code, asset_name, asset_group, asset_quantity,
asset_quantity - COALESCE(AA.allocated_quantity, 0) - COALESCE(AL.liquidated_quantity, 0) available_quantity
FROM asset A
LEFT JOIN (SELECT asset_id, SUM(allocated_quantity) allocated_quantity
FROM asset_allocation
GROUP BY asset_id) AA ON A.id = AA.asset_id
LEFT JOIN (SELECT asset_id, SUM(liquidated_quantity) liquidated_quantity
FROM asset_liquidated
GROUP BY asset_id) AL ON A.id = AL.asset_id
This query will give you -1 as available_quantity for asset_id 1 as you have only 5 available, 3 of them are allotted and 3 are liquidated as per your sample data.
Please see if this helps
SELECT
asset_quantity AS Total_Assets
,ISNULL(allocated_quantity, 0) allocated_quantity
,ISNULL(liquidated_quantity, 0) liquidated_quantity
FROM asset
LEFT OUTER JOIN (
SELECT
asset_id, SUM(allocated_quantity) AS allocated_quantity
FROM asset_allocation
GROUP BY asset_id
) asset_allocation2
ON asset_allocation2.asset_id = asset.id
LEFT OUTER JOIN (
SELECT
asset_id, SUM(liquidated_quantity) AS liquidated_quantity
FROM asset_liquidated
GROUP BY asset_id
) asset_liquidated 2
ON asset_liquidated 2.asset_id = asset.id
I'm trying to reduce storage with packages included in sold products.
Products can have different amounts of same packages and invoice can have different amounts of products in separate lines. Action should be performed against certain invoiceID.
Simplified tables (summary is not column, just added to ease up calculation):
Inv_rows
InvID ProdID Qty *Summary*
999 100 2 *100 = 10*
999 101 2 *101 = 2*
999 102 2 *102 = 2*
999 103 2 *103 = 10*
999 100 8
999 103 8
Pack_to_prod
ProdID PackID Qty
100 A 2 *A = 20*
100 B 1 *B = 10*
101 A 1 *A = 2*
101 B 1 *B = 2*
102 A 3 *A = 6*
103 B 2 *B = 20*
Storage
ItemID Qty
A 100 *A = 28*
B 100 *B = 32*
**Desired Result**
Storage
ItemID Qty
A 72 *(100-28)*
B 68 *(100-32)*
What I have tried is:
UPDATE Storage
SET Storage.Qty = Storage.Qty -
(SELECT SUM (Inv_rows.Qty * Pack_to_prod.Qty) FROM Inv_rows
WHERE Inv_rows.ProdID IN (SELECT ProdID FROM Pack_to_prod
WHERE Pack_to_prod.PackID=Storage.ItemID) AND Inv_rows.InvId = 999
)
FROM Inv_rows, Storage, Pack_to_prod
WHERE Inv_rows.ProdID = Pack_to_prod.ProdID
AND Pack_to_prod.PackID = Storage.ItemID
AND Inv_rows.InvID = 999
But the problem is the 'IN' since it doesn't match the rows but I can't use '=' as 'where' results more than one line.
Then I tried to simplify it for myself (as I'm not a professional) with a select clause to understand what exactly needs to be done..
SELECT
Pack_to_prod.PackID AS PackageID,
Inv_rows.ProdID AS ProductID,
Inv_rows.Qty AS ProductQty,
Pack_to_prod.Qty AS PackageQtyPerProduct,
Inv_rows.Qty*Pack_to_prod.Qty AS PackageTotal,
Storage.Qty AS StorageQty,
Storage.Qty - (Inv_rows.Qty * Pack_to_prod.Qty) AS NewStorageQty
FROM Pack_to_prod,Inv_rows,Storage
WHERE Inv_rows.ProdID = Pack_to_prod.ProdID
AND Pack_to_prod.PackID = Storage.ItemID
AND Inv_rows.InvID = 999
GROUP BY Inv_rows.ProdID, Pack_to_prod.PackID, Pack_to_prod.Qty, Storage.Qty, Inv_rows.Qty
Which results as simple list showing the problem why they can't be just summed up:
PackageID ProductID ProductQty PackageQtyPerProduct PackageTotal StorageQty NewStorageQty
A 100 2 2 4 100 96
A 100 8 2 16 100 84
B 100 2 1 2 100 98
B 100 8 1 8 100 92
A 101 2 1 2 100 98
B 101 2 1 2 100 98
A 102 2 3 6 100 94
B 103 2 2 4 100 96
B 103 8 2 16 100 84
But can't figure out how to make it run 'line by line' so that each 'Pack_to_prod.Qty' would be handled separately.
Any help in right direction appreciated.
This seems like some aggregations and joins. To get the changes in values, then:
select pp.packid, sum(p.qty * pp.qty) as new_qty
from (select ir.prodid, sum(qty) as qty
from inv_rows ir
group by ir.prodid
) p join
Pack_to_prod pp
on pp.prodid = p.prodid
group by pp.packid;
You can then use this in an update:
update s
set s.qty = s.qty - pp.new_qty
from storage s join
(select pp.packid, sum(p.qty * pp.qty) as new_qty
from (select ir.prodid, sum(qty) as qty
from inv_rows ir
group by ir.prodid
) p join
Pack_to_prod pp
on pp.prodid = p.prodid
group by pp.packid
) pp
on pp.packid = s.itemid;
This was explained very well. The SQL code is user older coding conventions (such as JOIN conditions in the WHERE clause, instead of FROM) and isn't organized into subqueries properly. All the pieces are present though. I think something like this is what you're looking for.
with
inv_cte(ProdID, sum_qty) as (
select ProdID, sum(Qty)
from Inv_rows
group by ProdID),
pack_cte(PackID, prod_qty) as (
select pp.PackID, sum(pp.Qty*ic.sum_qty)
from Pack_to_prod pp
join inv_cte ic on pp.ProdID=ic.ProdID
group by pp.PackID)
select s.ItemID, s.Qty-p.prod_qty as ResultQty
from Storage s
join pack_cte p on s.ItemID=p.PackID;
Update statement
with
inv_cte(ProdID, sum_qty) as (
select ProdID, sum(Qty)
from Inv_rows
group by ProdID),
pack_cte(PackID, prod_qty) as (
select pp.PackID, sum(pp.Qty*ic.sum_qty)
from Pack_to_prod pp
join inv_cte ic on pp.ProdID=ic.ProdID
group by pp.PackID)
update s
set Qty=Qty-p.prod_qty
from Storage s
join pack_cte p on s.ItemID=p.PackID;
Tables
TRANSACTIONS
SUPP_ID | PAYMENT
----------+----------
1001 200
1002 100
1005 250
MASTER_SUPPLIERS
SUPP_ID | AREA
----------+----------
1001 ABC
1002 XYZ
1003 TYU
1004 MNO
1005 PQR
Intention:
Find those count of suppliers area wise where no payment (NO_TRANS_CNT) has been received
SELECT AREA, COUNT(*) AS NO_TRANS_CNT FROM MASTER_SUPPLIERS
WHERE AREA NOT IN (SELECT DISTINCT(AREA) FROM TRANSACTIONS)
GROUP BY AREA
AREA | NO_TRANS_CNT
----------+--------------
TYU 1
MNO 1
Want to ask: Now, I also want to add the column TOTAL_SUPPLIERS in this area
AREA | TOTAL SUPPLIERS | NO_TRANS_CNT
----------+--------------------+----------------
ABC 1 0
XYZ 1 0
TYU 1 1
MNO 1 1
PQR 1 0
I think it can be achieved using JOINs, but I am not able to get how ?
Try this:
SELECT
M.AREA
, COUNT(1) TOTAL_SUPPLIERS
, COUNT(CASE WHEN T.SUPP_ID IS NULL THEN 1 END) NO_TRANS_CNT
FROM MASTER_SUPPLIERS M
LEFT JOIN TRANSACTIONS T ON T.SUPP_ID = M.SUPP_ID
GROUP BY M.AREA;
Something like
select M.AREA, COUNT(*) as TOTAL_SUPPLIERS, COUNT(T.PAYMENT) as NO_TRANS_CNT
from MASTER_SUPPLIERS M left join TRANSACTIONS T
on M.SUPP_ID = T.SUPP_ID
group by M.AREA;
could work.
Note that the COUNT(T.PAYMENT) only counts those where the PAYMENT is not NULL.
Use a left join, but start with suppliers:
select ms.area, count(*) as num_suppliers, count(t.supp_id) as num_transactions
from master_suppliers ms left join
transactions t
on t.supp_id = m.supp_id
group by ms.area;
The left join keeps everything in the first table -- which is what you want, along with matching rows from the second.
When you count the number of transactions, the argument to count() should either be a column used in the on clause or the primary key.
I have a case expression in a stored procedure summing an account field, and then inserting into a user id. The logic works... until joining to another table.
I tried adding distinct counts, and additional tables to the query, but still when I join to another table it applies the 1 value when I want it to be 0 to the account.
This is the calculation in the stored proc;
INSERT INTO #SUMMARY_TEMP (USER_ID,FSN_CNT )
(SELECT USER_ID,
SUM(CASE WHEN A_GROUP_CD = 'RED' AND A_TYPE_CD = 'FSN' THEN REC_COUNT ELSE 0 END)
) AS 'FSN_CNT',
FROM (SELECT A_ACCOUNT_NBR,
A_USER_ID,
A_GROUP_CD,
A_TYPE_CD,
COUNT(*) AS REC_COUNT
FROM EXCEPTION_DETAIL
INNER JOIN #STAFF ON A_REPORT_DT = #REPORT_DT
AND (A_USER = B_USER_ID)
GROUP BY A_ACCOUNT_NBR,
A_USER_ID_ID,
A_GROUP_CD,
A_TYPE_CD) EXCEPTIONS
GROUP BY A_USER_ID,
A_ACCOUNT_NBR)
This is the result which is what I expect for 2 USER Ids
A_ACCOUNT_NBR USER_ID FSN_CNT
123456 HENRY 0
123498 HENRY 1
374933 JOE 1
474930 JOE 0
but when I join to another table the data looks like
A_ACCOUNT_NBR USER_ID FSN_CNT
123456 HENRY 1
123498 HENRY 1
374933 JOE 1
474930 JOE 1
Its applying the 1 value to account 123456 & 474930 when it should be 0.
I think its because the other table does not have the ACCOUNT_NBR column - I am joining on USER_ID and so it applies the 1 to all ACCOUNT_NBR from table A.
Thanks for all the suggestions, I tried using a CTE, and the counts now look good, but its created duplicate rows as shown below. Any suggestions on how to remove the duplication, below is the join I am using for the CTE;
select cte.*, jt.USER_ID
from cte
join EXCEPTION_DETAIL jt on cte.USER_ID=jt.USER_ID
USER ACCOUNT_NBR FSN_CNT
HENRY 123456 0
HENRY 123456 0
HENRY 123498 1
HENRY 123498 1
JOE 374933 1
JOE 374933 1
JOE 474930 0
JOE 474930 0
you can separate the 1st query by using cte and join with it next level like below
with cte as
(
(SELECT USER_ID,
SUM(CASE WHEN A_GROUP_CD = 'RED' AND A_TYPE_CD = 'FSN' THEN REC_COUNT ELSE 0 END)
) AS 'FSN_CNT',
FROM (SELECT A_ACCOUNT_NBR,
A_USER_ID,
A_GROUP_CD,
A_TYPE_CD,
COUNT(*) AS REC_COUNT
FROM EXCEPTION_DETAIL
INNER JOIN #STAFF ON A_REPORT_DT = #REPORT_DT
AND (A_USER = B_USER_ID)
GROUP BY A_ACCOUNT_NBR,
A_USER_ID_ID,
A_GROUP_CD,
A_TYPE_CD) EXCEPTIONS
GROUP BY A_USER_ID,
A_ACCOUNT_NBR)
) select cte.*,jt.USER_ID from cte join jointable_name jt on cte.USER_ID=jt.USER_ID
