I'm trying to sum an amount from two different tables using a left join. I need all rows returned regardless of whether or not there is a match on the second table.
SELECT l.tender,
l.starting+SUM(t.amount) AS 'amount'
FROM label l
LEFT JOIN transfers t on l.tender=t.name
ORDER BY l.tender
This should work:
SELECT l.tender,
l.starting + ISNULL(t.amount,0) AS amount
FROM label l
LEFT JOIN ( SELECT name, SUM(amount) amount
FROM transfers
GROUP BY name) t
ON l.tender = t.name
ORDER BY l.tender
Wrap the SUM(amount) in a COALESCE function so that if there is no match and it is NULL, it will add 0 and won't mark the whole row as NULL.
Change line 2 of your query to look like this:
l.starting + COALESCE(SUM(t.amount), 0) AS amount
Edit:
As #Lamak noted, you also need to GROUP BY your results so that you can SUM it properly. The whole query can look like this (alternative to the other answer):
SELECT l.tender,
l.starting + COALESCE(SUM(t.amount), 0) AS amount
FROM label l
LEFT JOIN transfers t on l.tender=t.name
GROUP BY l.tender, l.starting
ORDER BY l.tender

I have the following table resulted from
SELECT m.MedName as [Medicine],m.MedSellPrice as [RetailPrice],m.MedType as [Type],
m.SoldQuantity as [Sold],m.Quantity as [Available],b.BillAmount as [Total Bill],b.BillDate
FROM BillMedicine AS bm LEFT JOIN
Medicine AS m
ON bm.MedicineID=m.id LEFT JOIN
Bill AS b
ON bm.BilIID = b. ID
but now I want to remove the repeated rows except the Sum of 'TotalBill'.
Use GROUP BY:
SELECT
m.MedName AS [Medicine],
m.MedSellPrice AS [RetailPrice],
m.MedType AS [Type],
m.SoldQuantity AS [Sold],
m.Quantity AS [Available],
SUM(b.BillAmount) AS [Total Bill]
FROM BillMedicine AS bm
LEFT JOIN Medicine AS m
ON bm.MedicineID = m.id
LEFT JOIN Bill AS b
ON bm.BilIID = b.ID
GROUP BY
m.MedName,
m.MedSellPrice,
m.MedType,
m.SoldQuantity,
m.Quantity;
Note that for the billing date, the two "duplicate" records you have highlighted have different dates. It is not clear which date, if any, you want to report here. I have omitted this column.
GROUP BY Is Best Option for DUPLICATE DATE Removed & SUM.
Select Column1,column2....., SUM(Total) as Total From Tablename Group BY column1,column2
You seem to want most (or all) columns from m and then the sum from another table. One method is a lateral join or correlated subquery:
SELECT m.*, -- or whatever columns you want,
(SELECT SUM(b.BillAmount)
FROM BillMedicine bm JOIN
Bill b
ON bm.BilIID = b.ID
WHERE bm.MedicineID = m.id
) as [Total Bill]
FROM Medicine m ;
I suggest this approach for several reasons.
This is often more efficient than an outer aggregation.
You have LEFT JOINs but they do not look correct. I suspect you want to start with the Medicine table.
You are including a date/time in the results, but clearly that is not appropriate when combining multiple rows.
I have a number of SKU's for sold/invoiced products in a database table, but some of the SKU's have extra data appended at the end of the SKU delimited by a pipe (Could be many pipes after base sku). i.e. I could have the same product SKU like this
correct-product-sku
correct-product-sku|assembled
correct-product-sku|assembled|custom
etc...
I want to join the product table against the invoice table like so.
SELECT COUNT(*) AS totalCount, productVariant.productKey
FROM invoiceItem
INNER JOIN productVariant ON invoiceItem.sku = productVariant.sku
But this will only join on the base SKU correct-product-sku and will ignore the others.
Is there an efficient way to split the invoiceItem.sku by the | and then use only the first part [0]. Obviously the SKU won't always have a | in it or could have one or many appended.
Any pointers would be appreciated.
You can use CHARINDEX and LEFT function as below to join your columns-
Code is bit edited considering if the Sku column hold only the real value without having any | in it.
SELECT COUNT(*) AS totalCount, productVariant.productKey
FROM invoiceItem
INNER JOIN productVariant
ON LEFT(
invoiceItem.sku,
CASE
WHEN CHARINDEX('|',invoiceItem.sku,0) = 0 THEN LEN(invoiceItem.sku)
ELSE CHARINDEX('|',invoiceItem.sku,0) -1
END
) = productVariant.sku
I was going to suggest the substring function but Left is more clear in this situation:
substring(invoiceItem.sku, 1, charindex('|', invoiceItem.sku)-1)
If the sku has a fixed length you can use the length instead of the charindex funtion.
You can use LIKE:
SELECT COUNT(*) AS totalCount, pv.productKey
FROM invoiceItem it INNER JOIN
productVariant pv
ON pv.sku LIKE i.sku + '|%'
GROUP BY pv.productKey;
I have this simple unioned query in SQL Server 2014 where I am getting counts of rows from each table, and then trying to add a TOTAL row at the bottom that will SUM the counts from both tables. I believe the problem is the LEFT OUTER JOIN on the last union seems to be only summing the totals from the first table
SELECT A.TEST_CODE, B.DIVISION, COUNT(*)
FROM ALL_USERS B, SIGMA_TEST A
WHERE B.DOMID = A.DOMID
GROUP BY A.TEST_CODE, B.DIVISION
UNION
SELECT E.TEST_CODE, F.DIVISION, COUNT(*)
FROM BETA_TEST E, ALL_USERS F
WHERE E.DOMID = F.DOMID
GROUP BY E.TEST_CODE, F.DIVISION
UNION
SELECT 'TOTAL', '', COUNT(*)
FROM (SIGMA_TEST A LEFT OUTER JOIN BETA_TEST E ON A.DOMID
= E.DOMID )
Here is a sample of the results I am getting:
I would expect the TOTAL row to display a result of 6 (2+1+3=6)
I would like to avoid using a Common Table Expression (CTE) if possible. Thanks in advance!
Since you are counting users with matching DOMIDs in the first two statements, the final statement also needs to include the ALL_USERS table. The final statement should be:
SELECT 'TOTAL', '', COUNT(*)
FROM ALL_USERS G LEFT OUTER JOIN
SIGMA_TEST H ON G.DOMID = H.DOMID
LEFT OUTER JOIN BETA_TEST I ON I.DOMID = G.DOMID
WHERE (H.TEST_CODE IS NOT NULL OR I.TEST_CODE IS NOT NULL)
I would consider doing a UNION ALL first then COUNT:
SELECT COALESCE(TEST_CODE, 'TOTAL'),
DIVISION,
COUNT(*)
FROM (
SELECT A.TEST_CODE, B.DIVISION
FROM ALL_USERS B
INNER JOIN SIGMA_TEST A ON B.DOMID = A.DOMID
UNION ALL
SELECT E.TEST_CODE, F.DIVISION
FROM BETA_TEST E
INNER JOIN ALL_USERS F ON E.DOMID = F.DOMID ) AS T
GROUP BY GROUPING SETS ((TEST_CODE, DIVISION ), ())
Using GROUPING SETS you can easily get the total, so there is no need to add a third subquery.
Note: I assume you want just one count per (TEST_CODE, DIVISION). Otherwise you have to also group on the source table as well, as in #Gareth's answer.
I think you can achieve this with a single query. It seems your test tables have similar structures, so you can union them together and join to ALL_USERS, finally, you can use GROUPING SETS to get the total
SELECT ISNULL(T.TEST_CODE, 'TOTAL') AS TEST_CODE,
ISNULL(U.DIVISION, '') AS DIVISION,
COUNT(*)
FROM ALL_USERS AS U
INNER JOIN
( SELECT DOMID, TEST_CODE, 'SIGNMA' AS SOURCETABLE
FROM SIGMA_TEST
UNION ALL
SELECT DOMID, TEST_CODE, 'BETA' AS SOURCETABLE
FROM BETA_TEST
) AS T
ON T.DOMID = U.DOMID
GROUP BY GROUPING SETS ((T.TEST_CODE, U.DIVISION, T.SOURCETABLE), ());
As an aside, the implicit join syntax you are using was replaced over a quarter of a century ago in ANSI 92. It is not wrong, but there seems to be little reason to continue to use it, especially when you are mixing and matching with explicit outer joins and implicit inner joins. Anyone else that might read your SQL will certainly appreciate consistency.
I have four tables,in which First has one to many relation with rest of three tables named as (Second,Third,Fourth) respectively.I want to sum only Distinct Rows returned by select query.Here is my query, which i try so far.
select count(distinct First.Order_id) as [No.Of Orders],sum( First.Amount) as [Amount] from First
inner join Second on First.Order_id=Second.Order_id
inner join Third on Third.Order_id=Second.Order_id
inner join Fourth on Fourth.Order_id=Third.Order_id
The outcome of this query is :
No.Of Orders Amount
7 69
But this Amount should be 49,because the sum of First column Amount is 49,but due to inner join and one to many relationship,it calculate sum of also duplicate rows.How to avoid this.Kindly guide me
I think the problem is cartesian products in the joins (for a given id). You can solve this using row_number():
select count(t1234.Order_id) as [No.Of Orders], sum(t1234.Amount) as [Amount]
from (select First.*,
row_number() over (partition by First.Order_id order by First.Order_id) as seqnum
from First inner join
Second
on First.Order_id=Second.Order_id inner join
Third
on Third.Order_id=Second.Order_id inner join
Fourth
on Fourth.Order_id=Third.Order_id
) t1234
where seqnum = 1;
By the way, you could also express this using conditions in the where clause, because you appear to be using the joins only for filtering:
select count(First.Order_id) as [No.Of Orders], sum(First.Amount) as [Amount]
from First
where exists (select 1 from second where First.Order_id=Second.Order_id) and
exists (select 1 from third where First.Order_id=third.Order_id) and
exists (select 1 from fourth where First.Order_id=fourth.Order_id);
I keep getting the wrong sum value when I join 3 tables.
Here is a pic of the ERD of the table:
(Original here: http://dl.dropbox.com/u/18794525/AUG%207%20DUMP%20STAN.png )
Here is the query:
select SUM(gpCutBody.actualQty) as cutQty , SUM(gpSewBody.quantity) as sewQty
from jobOrder
inner join gpCutHead on gpCutHead.joNum = jobOrder.joNum
inner join gpSewHead on gpSewHead.joNum = jobOrder.joNum
inner join gpCutBody on gpCutBody.gpCutID = gpCutHead.gpCutID
inner join gpSewBody on gpSewBody.gpSewID = gpSewHead.gpSewID
If you are only interested in the quantities of cuts and sews for all orders, the simplest way to do it would be like this:
select (select SUM(gpCutBody.actualQty) from gpCutBody) as cutQty,
(select SUM(gpSewBody.quantity) from gpSewBody) as sewQty
(This assumes that cuts and sews will always have associated job orders.)
If you want to see a breakdown of cuts and sews by job order, something like this might be preferable:
select joNum, SUM(actualQty) as cutQty, SUM(quantity) as sewQty
from (select joNum, actualQty, 0 as quantity
from gpCutBody
union all
select joNum, 0 as actualQty, quantity
from gpSewBody) sc
group by joNum
Mark's approach is a good one. I want to suggest the alternative of doing the group by's before the union, simply because this can be a more general approach for summing along multiple dimensions.
Your problem is that you have two dimensions that you want to sum along, and you are getting a cross product of the values in the join.
select joNum, act.quantity as ActualQty, q.quantity as Quantity
from (select joNum, sum(actualQty) as quantity
from gpCutBody
group by joNum
) act full outer join
(select joNum, sum(quantity) as quantity
from gpSewBody
group by joNum
) q
on act.joNum = q.joNum
(I have kept Mark's assumption that doing this by joNum is the desired output.)
