I have Table PREV:
Client Ctg
1 CC
1 OVD
2 CC
3 OVD
and table ACT:
Client Ctg
1 OVD
2 CC
4 OVD
And i need to count the difference between those two tables for each product (how many clients left the product and how many are new ones)
So the result should be left CC -1 , OVD -1 new ones OVD 1
Those results can be in two different selects
I tried this :
select count (*) from PREV left join ACT on client = client where
cliet is null group by Ctg
but this is not working when one client has more products... :/
Please note that there are thousands of clients and each of them can have up to 5 products (Ctg)
Plus in each month (ACT and PREV are like February/January) are clients which left and clients which are new. In final form i want to count new ones as well.
If you want the number of records that are in the one table and not the other, do a left/right join between them and count the number of nulls. IE:
SELECT a.Ctg, a.Client PrevClient, b.Client ActClient
FROM PREV a
LEFT JOIN ACT b ON a.Client = b.Client AND a.Ctg = b.Ctg
So now ActClient will be null where it there is a record in the PREV table that is NOT in the ACT table. You can then simply get the count by wrapping that SQL in another SQL statement. IE
SELECT Ctg, COUNT(*) FROM (
SELECT a.Ctg, a.Client PrevClient, b.Client ActClient
FROM PREV a
LEFT JOIN ACT b ON a.Client = b.Client AND a.Ctg = b.Ctg
) Tmp
WHERE ActClient IS NULL
GROUP BY Ctg
So to get the count of the record in ACT that are not in PREV, you can simply use the same query with a RIGHT join. and change the a.Ctg to b.Ctg
you tried something like this?
select a.ctg,a.sum2-b.sum1 from
(select ctg, count(*) sum2 from prev group by ctg)a,
(select act.ctg ctg, count(*) sum1 from prev join act
on prev.client=act.client and prev.ctg=act.ctg group by act.ctg)b;
cte is doing calculation for PREV counts and then comparing with current counts.
; with cte
as
( select prev.Ctg, COUNT(ctg) as prevCount
from PREV
group by prev.Ctg
)
SELECT ACT.Ctg , COUNT(act.ctg) - cte.prevCount as Difference, COUNT(act.ctg) as CurrentCount, cte.prevCount as PrevCount
from ACT
join cte
on act.Ctg = cte.Ctg
group by ACT.Ctg, cte.prevCount
basic version:
SELECT COUNT(*) FROM [ACT] as a
where not exists (select * from [PREV] as p
where a.Client = p.Client and a.Ctg = p.Ctg)
ok, so thet try this one:
select a.Ctg, COUNT(a.Client) as ClientCoutThatAddThatCategory
from ACT as a
left outer join PREV as p
on a.Client=p.Client and a.Ctg=p.Ctg
where p.Client is NULL
group by a.Ctg
select p.Ctg, COUNT(p.Client) as ClientCoutThatLeftThatCategory
from ACT as a
right outer join PREV as p
on a.Client=p.Client and a.Ctg=p.Ctg
where a.Client is NULL
group by p.Ctg

Can anyone help I'm new to SQL and trying to figure out the below question see image for the table structure;
Question = Select account name, contact last name, case number, quote number, quote date and quote value for the f third-largest quote ever created for each of the accounts in the EC1 area
So far I got;
Select
a.accountname, cc.lastname, c.casenumber,
q.quotenumber, q.quotedate, q.quotevalue
from
TBL_Quote q
Left join
TBL_case c On q.caseid = c.caseid
Left join
tbl_contact cc On c.contactID = cc. contactID
Left join
tbl_account a On a.accountid = cc.accountid
Where
left(a.postcode, 3) like 'EC1'
and for the third:
SELECT TOP 1 value
FROM
(SELECT DISTINCT TOP 3 value
FROM tbl_quote
ORDER BY value DESC) a
ORDER BY value
I can't seem to combine the top 3 and the query is it best to overpartion by ?
I would suggest joins and a row-limiting clause:
select ac.accountName, co.lastName, ca.caseNumber, qu.quoteNumber
from tbl_account ac
inner join tbl_contact co on co.accountId = ac.accountId
inner join tbl_case ca on ca.contactId = co.contactId
inner join tbl_quote qu on qu.caseId = ca.quoteId
where ac.postcode like 'EC1%'
order by len(qu.value) desc
offset 2 rows fetch next 1 row only
thanks in advance for you help. I'm still quite new to MS SQL db but I was wondering why my recursive query for MSSQL below does not return the value i'm expecting. I've done my research and at the bottom is the code I came up with. Lets say I have the following table...
CategoryID ParentID SomeName
1 0 hmm
2 0 err
3 0 woo
4 3 ppp
5 4 ttt
I'm expecting the query below to return 3 4 5. I basically wanted to get the list of category id's heirarchy below it self inclusive based on the category id I pass in the recursive query. Thanks for you assistance.
GO
WITH RecursiveQuery (CategoryID)
AS
(
-- Anchor member definition
SELECT a.CategoryID
FROM [SomeDB].[dbo].[SomeTable] AS a
WHERE a.ParentID = CategoryID
UNION ALL
-- Recursive member definition
SELECT b.CategoryID
FROM [SomeDB].[dbo].[SomeTable] AS b
INNER JOIN RecursiveQuery AS d
ON d.CategoryID = b.ParentID
)
-- Statement that executes the CTE
SELECT o.CategoryID
FROM [SomeDB].[dbo].[SomeTable] AS o
INNER JOIN RecursiveQuery AS d
ON d.CategoryID = 3
GO
If you want tree from specific root:
DECLARE #rootCatID int = 3
;WITH LessonsTree (CatID)
AS
(
SELECT a.CategoryID
FROM [EducationDatabase].[dbo].[LessonCategory] AS a
WHERE a.CategoryID = #rootCatID ---<<<
UNION ALL
SELECT b.CategoryID
FROM LessonsTree as t
INNER JOIN [EducationDatabase].[dbo].[LessonCategory] AS b
ON b.ParentID = t.CatID
)
SELECT o.*
FROM LessonsTree t
INNER JOIN [EducationDatabase].[dbo].[LessonCategory] AS o
ON o.CategoryID = t.CatID
As stated in the comments, the anchor isn't restricted. Easiest solution is to add the criterium in the anchor
with RecursiveQuery (theID)
AS
(
SELECT a.ParentID --root id=parentid to include it and to prevent an extra trip to LessonCategory afterwards
FROM [LessonCategory] AS a
WHERE a.ParentID = 3 --restriction here
UNION ALL
SELECT b.CategoryID
FROM [LessonCategory] AS b
INNER JOIN RecursiveQuery AS d
ON d.theID = b.ParentID
)
SELECT* from RecursiveQuery
Another option is to have the recursive query be general (no restricted anchor) and have it keep the rootid as well. Then the query on the cte can restrict on the rootid (the first option is probably better, this second one is mainly suitable if you are created some sort of root-view)
with RecursiveQuery
AS
(
SELECT a.ParentID theID, a.ParentID RootID
FROM [LessonCategory] AS a
UNION ALL
SELECT b.CategoryID, d.RootID
FROM [LessonCategory] AS b
INNER JOIN RecursiveQuery AS d
ON d.theID = b.ParentID
)
SELECT theID from RecursiveQuery where RootID = 3
I have a complex query to retrieve some results:
EDITED QUERY (added the UNION ALL):

LEFT JOIN dbo.Assunto ON dbo.Servico.SNT_Id = dbo.Assunto.SNT_Id
) t
The result is following:
It works good, the problem is that I was asked that if when a row is not present on this query, it must contain values from another table (ServicoAreaTecnica), so I got this query for the other table based on crucial information of the first query. So if I UNION ALL I get this:
Query1 +
UNION ALL
SELECT INN.INT_Processo,
PES.PFJ_Descri,
NULL, --ETS.ETS_Sigla,
ART.ATC_Sigla,
NULL ,--PAT.PAT_Sigla,
ASS.SNT_Peso,
NULL, --PESOAREA
NULL, --DATA_INICIO_TERMINO
NULL --seqnum
FROM dbo.ServicoAreaTecnica AS SAT
INNER JOIN dbo.AreaTecnica AS ART ON ART.ATC_Id = SAT.ATC_Id
INNER JOIN dbo.Servico AS SER ON SER.SRV_Id = SAT.SRV_Id
INNER JOIN dbo.Assunto AS ASS ON ASS.SNT_Id = SER.SNT_Id
INNER JOIN dbo.Intervencao AS INN ON INN.INT_Id = SER.INT_Id
INNER JOIN dbo.Pessoa AS PES ON PES.PFJ_Id = SAT.PFJ_Id_Analista
The result is following:
So what I want to do is to remove row number 1 because row number 2 exists on the first query, I think I got it explained better this time. The result should be only row number 1, row number 2 would appear only if query 1 doesn't retrieve a row for that particular INN.INT_Processo.
Thanks!
Ok, there are two ways to reduce your record set. Given that you've already written the code to produce the table with the extra rows, it might be easiest to just add code to reduce that:
Select * from
(Select *
, Row_Number() over
(partition by IntProcesso, Analista order by ISNULL(seqnum, 0) desc) as RN
from MyResults) a
where RN = 1
This will assign row_number 1 to any rows that came from your first query, or to any rows from the second query that do not have matches in the first query, then filter out extra rows.
You could also use outer joins with isnull or coalesce, as others have suggested. Something like this:
Select ISNULL(a.IntProcesso, b.IntProcesso) as IntProcesso
, ISNULL(a.Analista, b.Analista) as Analista
, ISNULL(a.ETSsigla, b.ETSsigla) as ETSsigla
[repeat for the rest of your columns]
from Table1 a
full outer join Table2 b
on a.IntProcesso = b.IntProcesso and a.Analista = b.Analista
Your code is hard to read, because of the lengthy names of everything (and to be honest, the fact that they're in a language I don't speak also makes it a lot harder).
But how about: replacing your INNER JOINs with LEFT JOINs, adding more LEFT JOINs to draw in the alternative tables, and introducing ISNULL clauses for each variable you want in the results?
If you do something like ... Query1 Right Join Query2 On ... that should get only the rows in Query2 that don't appear in Query 1.
I wrote two queries below that produce one row of data each.
What is the best way to combine them such that I am LEFT with only a single row of data?
These are coming FROM two DISTINCT databases named : [ASN01] and [dsi_ASN_dsicx]
I have 70 pairs of databases like this but am showing only one for simplicity.
The fact that the three letter acronym ASN is common to both database names is no mistake and if needed can be a part of the solution.
Current Results:
Site, Elligence (header)
ASN, 100.00
Site, GP_Total (header)
ASN, 120.00
Desired results:
Site, GP_Total, Elligence (header)
ASN, 120.00, 100.00
SELECT 'ASN' AS Site ,
CASE SUM(perdblnc)
WHEN NULL THEN 0
ELSE -1 * SUM(PERDBLNC)
END AS GP_Total
FROM [ASN01].[dbo].[GL10110] T1
LEFT OUTER JOIN [ASN01].[dbo].[GL00105] T2 ON [T1].[ACTINDX] = [T2].[ACTINDX]
WHERE YEAR1 = 2012
AND PERIODID IN ( '2' )
AND ACTNUMST IN ( '4200-0000-C', '6940-0000-C', '6945-0000-C',
'6950-0000-C' )
SELECT 'ASN' AS [Site] ,
SUM(pi.amount) AS [Elligence]
FROM [dsi_ASN_dsicx].dbo.charge c
LEFT JOIN [dsi_ASN_dsicx].dbo.paymentitem pi ON c.idcharge = pi.chargeid
LEFT JOIN [dsi_ASN_dsicx].dbo.payment p ON pi.paymentid = p.idpayment
LEFT JOIN [dsi_ASN_dsicx].dbo.paymenttype pt ON p.paymenttypeid = pt.idpaymenttype
WHERE pi.amount != 0
AND pt.paymentmethod NOT IN ( '5', '7' )
AND pt.paymentmethod IS NOT NULL
AND p.sdate >= '20120201'
AND p.sdate <= '20120229'
WIthout going through and changing any of your queries, the easiest way would be to use temp tables using the "WITH" common_table_expression. Table1 and Table2 are temp tables created from your select statements. Therefore, we select table1 and join table2.
Let me know if there are any syntax problems, I don't have anything to test this on presently.
;With Table1 as (SELECT 'ASN' as Site, Case sum(perdblnc)
WHEN NULL THEN 0
ELSE -1*sum(PERDBLNC) END as GP_Total
FROM [ASN01].[dbo].[GL10110] T1
Left Outer Join [ASN01].[dbo].[GL00105] T2
ON [T1]. [ACTINDX]= [T2]. [ACTINDX]
WHERE YEAR1 = 2012
AND PERIODID in ('2')
AND ACTNUMST in ('4200-0000-C', '6940-0000-C', '6945-0000-C', '6950-0000-C'))
, Table2 as (SELECT
'ASN' as [Site],
SUM(pi.amount) as [Elligence]
FROM [dsi_ASN_dsicx].dbo.charge c
LEFT JOIN [dsi_ASN_dsicx].dbo.paymentitem pi on c.idcharge = pi.chargeid
LEFT JOIN [dsi_ASN_dsicx].dbo.payment p on pi.paymentid = p.idpayment
LEFT JOIN [dsi_ASN_dsicx].dbo.paymenttype pt on p.paymenttypeid = pt.idpaymenttype
WHERE pi.amount != 0
AND pt.paymentmethod not in ('5','7')
AND pt.paymentmethod is not null
AND p.sdate >='20120201' and p.sdate <= '20120229')
SELECT * FROM Table1
LEFT JOIN Table2 ON Table1.site = Table2.site
Hope this helps! Marks as answer if it is =)
Having issues getting a dataset to return with one date per client in the query.
Requirements:
Must have the recent date of transaction per client list for user
Will need have the capability to run through EXEC
Current Query:
SELECT
c.client_uno
, c.client_code
, c.client_name
, c.open_date
into #AttyClnt
from hbm_client c
join hbm_persnl p on c.resp_empl_uno = p.empl_uno
where p.login = #login
and c.status_code = 'C'
select
ba.payr_client_uno as client_uno
, max(ba.tran_date) as tran_date
from blt_bill_amt ba
left outer join #AttyClnt ac on ba.payr_client_uno = ac.client_uno
where ba.tran_type IN ('RA', 'CR')
group by ba.payr_client_uno
Currently, this query will produce at least 1 row per client with a date, the problem is that there are some clients that will have between 2 and 10 dates associated with them bloating the return table to about 30,000 row instead of an idealistic 246 rows or less.
When i try doing max(tran_uno) to get the most recent transaction number, i get the same result, some have 1 value and others have multiple values.
The bigger picture has 4 other queries being performed doing other parts, i have only included the parts that pertain to the question.
Edit (2011-10-14 # 1:45PM):
select
ba.payr_client_uno as client_uno
, max(ba.row_uno) as row_uno
into #Bills
from blt_bill_amt ba
inner join hbm_matter m on ba.matter_uno = m.matter_uno
inner join hbm_client c on m.client_uno = c.client_uno
inner join hbm_persnl p on c.resp_empl_uno = p.empl_uno
where p.login = #login
and c.status_code = 'C'
and ba.tran_type in ('CR', 'RA')
group by ba.payr_client_uno
order by ba.payr_client_uno
--Obtain list of Transaction Date and Amount for the Transaction
select
b.client_uno
, ba.tran_date
, ba.tc_total_amt
from blt_bill_amt ba
inner join #Bills b on ba.row_uno = b.row_uno
Not quite sure what was going on but seems the Temp Tables were not acting right at all. Ideally i would have 246 rows of data, but with the previous query syntax it would produce from 400-5000 rows of data, obviously duplications on data.
I think you can use ranking to achieve what you want:
WITH ranked AS (
SELECT
client_uno = ba.payr_client_uno,
ba.tran_date,
be.tc_total_amt,
rnk = ROW_NUMBER() OVER (
PARTITION BY ba.payr_client_uno
ORDER BY ba.tran_uno DESC
)
FROM blt_bill_amt ba
INNER JOIN hbm_matter m ON ba.matter_uno = m.matter_uno
INNER JOIN hbm_client c ON m.client_uno = c.client_uno
INNER JOIN hbm_persnl p ON c.resp_empl_uno = p.empl_uno
WHERE p.login = #login
AND c.status_code = 'C'
AND ba.tran_type IN ('CR', 'RA')
)
SELECT
client_uno,
tran_date,
tc_total_amt
FROM ranked
WHERE rnk = 1
ORDER BY client_uno
