I am trying to get results of a customer from two linked servers remotely. i need to sum the points of every cust_id but am having problems with my query
SELECT sum(cust_point) as total
FROM [192.168.23.9].[POSDBV4].[dbo].[loyal_summery_branch] where cust_id='0100015388'
INNER JOIN [192.168.13.4].[POSDBV4].[dbo].[loyal_summery_branch]
ON cust_id.[192.168.23.9].[POSDBV4].[dbo].[loyal_summery_branch]=cust_id.[192.168.13.4].[POSDBV4].[dbo].[loyal_summery_branch];
I think you have your query syntax a little scrambled there. Try this.
SELECT sum(cust_point) as total
FROM [192.168.23.9].[POSDBV4].[dbo].[loyal_summery_branch] A
INNER JOIN [192.168.13.4].[POSDBV4].[dbo].[loyal_summery_branch] B ON A.cust_id=B.cust_id
WHERE cust_id='0100015388'
As you want the sum of cust_point of both of the table. Please find the query below
Select( (SELECT sum(cust_point)
FROM [192.168.23.9].[POSDBV4].[dbo].[loyal_summery_branch] where cust_id='0100015388') +
(SELECT sum(cust_point)
FROM [192.168.13.4].[POSDBV4].[dbo].[loyal_summery_branch] where cust_id='0100015388') ) as total
you can always use a UNION ALL here if you like.. this will allow you select other fields as well if you include a GROUP BY
SELECT SUM(cust_point) AS total
FROM (
SELECT cust_point
FROM [192.168.23.9].[POSDBV4].[dbo].[loyal_summery_branch]
WHERE cust_id = '0100015388'
UNION ALL
SELECT cust_point
FROM [192.168.13.4].[POSDBV4].[dbo].[loyal_summery_branch]
WHERE cust_id = '0100015388'
) t

I am writing a query but i'm getting wrong result.Table are follows:
Tbl1(ProId, price,VId)
Tbl2(ProId, price, VId)
I have written this query:
SELECT
a.ProId, b.ProId,
SUM(a.price) - SUM(b.price) AS TotalPro
FROM
tbl1 AS a
INNER JOIN
tbl2 AS b ON a.ProId = b.ProId
WHERE
a.VId = '1234'
GROUP BY
a.ProId, b.ProId;
This query is returning an incorrect answer. What I have done is sum the price from table one and two separately and minus them the answer was fine. But when I join, I don't know why I am getting the wrong answer. ProId is same in both table, values are same.
I guess you want sth like below:
SELECT ProdId, SUM(price)
FROM (
SELECT a.ProId,a.price
FROM Tbl1 a
WHERE a.VId='1234'
UNION ALL
SELECT b.ProdId, -b.price
FROM Tbl2 b
--WHERE b.VId ='1234' (?)
) sub
GROUP BY ProdId;
The issue with JOIN is you may have some rows that are summed multiple times.
I am relatively new at SQL so I apologise if this is obvious but I cannot work out how to use the results of the WITH clause query in the where statement of my main query.
My with query pulls the first record for each customer and gives the sale date for that record:
WITH summary AS(
SELECT ed2.customer,ed2.saledate,
ROW_NUMBER()OVER(PARTITION BY ed2.customer
ORDER BY ed2.saledate)AS rk
FROM Filteredxportdocument ed2)
SELECT s.*
FROM summary s
WHERE s.rk=1
I need to use the date in the above query as the starting point and pull all records for each customer for their first 12 months i.e. where the sale date is between ed2.saledate AND ed2.saledate+12 months.
My main query is:
SELECT ed.totalamountincvat, ed.saledate, ed.name AS SaleRef,
ed.customer, ed.customername, comp.numberofemployees,
comp.companyuid
FROM exportdocument AS ed INNER JOIN
FilteredAccount AS comp ON ed.customer = comp.accountid
WHERE (ed.statecode = 0) AND
ed.saledate BETWEEN ed2.saledate AND DATEADD(M,12,ed2.saledate)
I am sure that I need to add the main query into the WITH clause but I cant work out where. Is anyone able to help please
Does this help?
;WITH summary AS(
SELECT ed2.customer,ed2.saledate,
ROW_NUMBER()OVER(PARTITION BY ed2.customer
ORDER BY ed2.saledate)AS rk
FROM Filteredxportdocument ed2)
SELECT ed.totalamountincvat, ed.saledate, ed.name AS SaleRef,
ed.customer, ed.customername, comp.numberofemployees,
comp.companyuid
FROM exportdocument AS ed INNER JOIN
FilteredAccount AS comp ON ed.customer = comp.accountid
OUTER APPLY (SELECT s.* FROM summary s WHERE s.rk=1) ed2
WHERE ed.statecode = 0 AND
ed.saledate BETWEEN ed2.saledate AND DATEADD(M,12,ed2.saledate)
and ed.Customer = ed2.Customer
Results of CTE are not cached or stored, so you can't reuse it.
EDIT:
Based upon your requirement that all the records from CTE should be in final result, this is a new query:
;WITH summary AS(
SELECT ed2.customer,ed2.saledate,
ROW_NUMBER()OVER(PARTITION BY ed2.customer
ORDER BY ed2.saledate)AS rk
FROM Filteredxportdocument ed2)
SELECT
ed.totalamountincvat,
ed.saledate,
ed.name AS SaleRef,
ed.customer,
ed.customername,
comp.numberofemployees,
comp.companyuid
FROM
summary ed2
left join exportdocument ed
on ed.Customer = ed2.Customer
and ed.statecode = 0
AND ed.saledate BETWEEN ed2.saledate AND DATEADD(M,12,ed2.saledate)
INNER JOIN FilteredAccount comp
ON ed.customer = comp.accountid
WHERE
s.rk=1
summary you will be able to use only once. Alternate solution is store summary into temp table and use that as many times as u want.
Something like : Select * into #temp from Summary s where s.rk=1
I inherit an old SQL script that I want to optimize but after several tests, I must admit that all my tests only creates huge SQL with repetitive blocks. I would like to know if someone can propose a better code for the following pattern (see code below). I don't want to use temporary table (WITH). For simplicity, I only put 3 levels (table TMP_C, TMP_D and TMP_E) but the original SQL have 8 levels.
WITH
TMP_A AS (
SELECT
ID,
Field_X
FROM A
TMP_B AS(
SELECT DISTINCT
ID,
Field_Y,
CASE
WHEN Field_Z IN ('TEST_1','TEST_2') THEN 'CATEG_1'
WHEN Field_Z IN ('TEST_3','TEST_4') THEN 'CATEG_2'
WHEN Field_Z IN ('TEST_5','TEST_6') THEN 'CATEG_3'
ELSE 'CATEG_4'
END AS CATEG
FROM B
INNER JOIN TMP_A
ON TMP_A.ID=TMP_B.ID),
TMP_C AS (
SELECT DISTINCT
ID,
CATEG
FROM TMP_B
WHERE CATEG='CATEG_1'),
TMP_D AS (
SELECT DISTINCT
ID,
CATEG
FROM TMP_B
WHERE CATEG='CATEG_2' AND ID NOT IN (SELECT ID FROM TMP_C)),
TMP_E AS (
SELECT DISTINCT
ID,
CATEG
FROM TMP_B
WHERE CATEG='CATEG_3'
AND ID NOT IN (SELECT ID FROM TMP_C)
AND ID NOT IN (SELECT ID FROM TMP_D))
SELECT * FROM TMP_C
UNION
SELECT * FROM TMP_D
UNION
SELECT * FROM TMP_E
Many thanks in advance for your help.
First off, select DISTINCT will prevent duplicates from the result set, so you are overworking the condition. By adding the "WITH" definitions and trying to nest their use makes it more confusing to follow. The data is ultimately all coming from the "B" table where also has key match in "A". Lets start with just that... And since you are not using anything from the (B)Field_Y or (A)Field_X in your result set, don't add them to the mix of confusion.
SELECT DISTINCT
B.ID,
CASE WHEN B.Field_Z IN ('TEST_1','TEST_2') THEN 'CATEG_1'
WHEN B.Field_Z IN ('TEST_3','TEST_4') THEN 'CATEG_2'
WHEN B.Field_Z IN ('TEST_5','TEST_6') THEN 'CATEG_3'
ELSE 'CATEG_4'
END AS CATEG
FROM
B JOIN A ON B.ID = A.ID
WHERE
B.Field_Z IN ( 'TEST_1', 'TEST_2', 'TEST_3', 'TEST_4', 'TEST_5', 'TEST_6' )
The where clause will only include those category qualifying values you want and still have the results per each category.
Now, if you actually needed other values from your "Field_Y" or "Field_X", then that would generate a different query. However, your Tmp_C, Tmp_D and Tmp_E are only asking for the ID and CATEG columns anyhow.
This may perform better
SELECT DISTINCT B.ID, 'CATEG_1'
FROM
B JOIN A ON B.ID = A.ID
WHERE
B.Field_Z IN ( 'TEST_1', 'TEST_2')
UNION
SELECT DISTINCT B.ID, 'CATEG_2'
FROM
B JOIN A ON B.ID = A.ID
WHERE
B.Field_Z IN ( 'TEST_3', 'TEST_4')

I'm pulling my hair out over a subquery that I'm using to avoid about 100 duplicates (out of about 40k records). The records that are duplicated are showing up because they have 2 dates in h2.datecreated for a valid reason, so I can't just scrub the data.
I'm trying to get only the earliest date to return. The first subquery (that starts with "select distinct address_id", with the MIN) works fine on it's own...no duplicates are returned. So it would seem that the left join (or just plain join...I've tried that too) couldn't possibly see the second h2.datecreated, since it doesn't even show up in the subquery. But when I run the whole query, it's returning 2 values for some ipc.mfgid's, one with the h2.datecreated that I want, and the other one that I don't want.
I know it's got to be something really simple, or something that just isn't possible. It really seems like it should work! This is MSSQL. Thanks!

The typical approach to only getting the lowest row is one of the following. You didn't bother to specify what version of SQL Server you're using, what you want to do with ties, and I have little interest to try to work this into your complex query, so I'll show you an abstract simplification for different versions.
SQL Server 2000
SELECT x.grouping_column, x.min_column, x.other_columns ...
FROM dbo.foo AS x
INNER JOIN
(
SELECT grouping_column, min_column = MIN(min_column)
FROM dbo.foo GROUP BY grouping_column
) AS y
ON x.grouping_column = y.grouping_column
AND x.min_column = y.min_column;
SQL Server 2005+
;WITH x AS
(
SELECT grouping_column, min_column, other_columns,
rn = ROW_NUMBER() OVER (ORDER BY min_column)
FROM dbo.foo
)
SELECT grouping_column, min_column, other_columns
FROM x
WHERE rn = 1;
This subqery:
select distinct address_id, equipment_id,
min(datecreated) as datecreated, comment
from history where comment like 'MAC: 5%' group by equipment_id, address_id, comment
Probably will return multiple rows because the comment is not guaranteed to be the same.
Try this instead:
CROSS APPLY (
SELECT TOP 1 H2.DateCreated, H2.Comment -- H2.Equipment_id wasn't used
FROM History H2
WHERE
H2.Comment LIKE 'MAC: 5%'
AND C.Address_ID = H2.Address_ID
ORDER BY DateCreated
) H2
Switch that to OUTER APPLY in case you want rows that don't have a matching desired history entry.
I have 2 tables, that look like:
CustomerInfo(CustomterID, CustomerName)
CustomerReviews(ReviewID, CustomerID, Review, Score)
I want to search reviews for a string and return CustomerInfo.CustomerID and CustomerInfo.CustomerName. However, I only want to show distinct CustomerID and CustomerName along with just one of their CustomerReviews.Reviews and CustomerReviews.Score. I also want to order by the CustomerReviews.Score.
I can't figure out how to do this, since a customer can leave multiple reviews, but I only want a list of customers with their highest scored review.
Any ideas?
This is the greatest-n-per-group problem that has come up dozens of times on Stack Overflow.
Here's a solution that works with a window function:
WITH CustomerCTE (
SELECT i.*, r.*, ROW_NUMBER() OVER (PARTITION BY CustomerID ORDER BY Score DESC) AS RN
FROM CustomerInfo i
INNER JOIN CustomerReviews r ON i.CustomerID = r.CustomerID
WHERE CONTAINS(r.Review, '"search"')
)
SELECT * FROM CustomerCTE WHERE RN = 1
ORDER BY Score;
And here's a solution that works more broadly with RDBMS brands that don't support window functions:
SELECT i.*, r1.*
FROM CustomerInfo i
INNER JOIN CustomerReviews r1 ON i.CustomerID = r1.CustomerID
AND CONTAINS(r1.Review, '"search"')
LEFT OUTER JOIN CustomerReviews r2 ON i.CustomerID = r2.CustomerID
AND CONTAINS(r1.Review, '"search"')
AND (r1.Score < r2.Score OR r1.Score = r2.Score AND r1.ReviewID < r2.ReviewID)
WHERE r2.CustomerID IS NULL
ORDER BY Score;
I'm showing the CONTAINS() function because you should be using the fulltext search facility in SQL Server, not using LIKE with wildcards.
I voted for Bill Karwin's answer, but I thought I'd throw out another option.
It uses a correlated subquery, which can often incur performance problems with large data sets, so use with caution. I think the only upside is that the query is easier to immediately understand.
select *
from [CustomerReviews] r
where [ReviewID] =
(
select top 1 [ReviewID]
from [CustomerReviews] rInner
where rInner.CustomerID = r.CustomerID
order by Score desc
)
order by Score desc
I didn't add the string search filter, but that can be easily added.
I think this should do it
select ci.CustomterID, ci.CustomerName, cr.Review, cr.Score
from CustomerInfo ci inner join
(select top 1*
from CustomerReviews
where Review like '%search%'
order by Score desc) cr on ci.CustomterID = cr.CustomterID
order by cr.Score
