How can i remove an group result sql - sql

Question

I have a SQL query but it gives me more results that I want. For example when I run the query I will get 20 results from 2 products. Each product has a group by and the group by of the g.linkedline must be ignored and not shown in the results.
This is the query that I have
I tried to make a select over my select. I also tried a TOP 1 but it gives me 1 result.
SELECT i.itemcode,
g.warehouse,
Sum(g.aantal) AS Voorraad,
Max(CASE
WHEN g.transtype = 'N' THEN g.sysmodified
ELSE NULL
END) AS LastDate
FROM dbo.gbkmut AS g
INNER JOIN dbo.items AS i
ON g.artcode = i.itemcode
AND g.reknr = i.glaccountdistribution
AND ( g.transtype = 'N'
OR ( g.transtype = 'B'
AND g.transsubtype = 'B'
AND g.freefield1 NOT IN ( 'B', 'Q', 'W', 'K' )
AND g.blockitem = '0'
AND g.allocationtype = 'F' )
OR ( g.transtype = 'B'
AND g.transsubtype = 'B'
AND g.freefield1 = 'V'
AND g.allocationtype = 'B' ) )
WHERE g.transtype = 'N'
AND ( i.itemcode = 'TESTARTIKEL'
OR i.itemcode = 'IQ7-60-2-INT' )
GROUP BY i.itemcode,
g.warehouse,
g.linkedline

Answer 1

I'd try it like this, you can use the window function row_number to force a ranking. If you are interested in only 1 thing per unique item code or where house, the nyou substitute the thing of interest in the Partition by clause and then specify what you want to order on in the order by clause. For example in the query below the item of interest is the ItemCode and we are ordering on the warehouse and aantal desc (which I'm assuming you want to see items with more aantal than less, but you can remove desc if you that suits your needs.
select * from
(
SELECT row_number()over(partition by i.Itemcode order by g.warehouse, g.aantal desc) as rowno, i.ItemCode, g.warehouse, SUM(g.aantal) AS Voorraad, MAX(CASE WHEN g.transtype = 'N' THEN g.sysmodified ELSE NULL END) AS LastDate
FROM dbo.gbkmut AS g INNER JOIN dbo.Items AS i
ON g.artcode = i.ItemCode AND g.reknr = i.GLAccountDistribution AND (
g.transtype = 'N' OR
(g.transtype = 'B' AND
g.transsubtype = 'B' AND
g.freefield1 NOT IN ('B', 'Q', 'W', 'K') AND
g.BlockItem = '0' AND
g.AllocationType = 'F') OR ( g.transtype = 'B' AND g.transsubtype = 'B' AND g.freefield1 = 'V' AND g.AllocationType = 'B'))
WHERE g.transtype = 'N' AND (i.ItemCode = 'TESTARTIKEL' OR i.ItemCode = 'IQ7-60-2-INT') GROUP BY i.ItemCode, g.warehouse, g.LinkedLine
) x where rowno=1;

SELECT i.ItemCode, g.warehouse, SUM(g.aantal) AS Voorraad,
MAX(CASE WHEN g.transtype = 'N' THEN g.sysmodified ELSE NULL END) AS LastDate
FROM dbo.gbkmut AS g INNER JOIN dbo.Items AS i
ON g.artcode = i.ItemCode AND g.reknr = i.GLAccountDistribution AND (
g.transtype = 'N' OR
(g.transtype = 'B' AND
g.transsubtype = 'B' AND
g.freefield1 NOT IN ('B', 'Q', 'W', 'K') AND
g.BlockItem = '0' AND
g.AllocationType = 'F') OR ( g.transtype = 'B' AND g.transsubtype = 'B' AND g.freefield1 = 'V' AND g.AllocationType = 'B'))
WHERE g.transtype = 'N' AND i.ItemCode = 'IQ7-60-2-INT' GROUP BY i.ItemCode, g.warehouse, g.LinkedLine
This returns results first Voorraad 0 and with the script of DwightReynoldson it returns 1080

Answer 3

I found the problem. thank you all!
There was a desc to the Voorraad thats is why the result wasn't correct.
This is the Code
select * from
(
SELECT
i.ItemCode,
g.warehouse,
SUM(g.aantal) AS Voorraad,
MAX(CASE
WHEN g.transtype = 'N' THEN g.sysmodified
ELSE NULL
END) AS LastDate,
row_number()
over
(partition by
i.Itemcode
order by
g.warehouse
) as rowno
FROM dbo.gbkmut AS g
INNER JOIN dbo.Items AS i
ON g.artcode = i.ItemCode
AND g.reknr = i.GLAccountDistribution
AND ( g.transtype = 'N'
OR ( g.transtype = 'B'
AND g.transsubtype = 'B'
AND g.freefield1 NOT IN ( 'B', 'Q', 'W', 'K' )
AND g.blockitem = '0'
AND g.allocationtype = 'F' )
OR ( g.transtype = 'B'
AND g.transsubtype = 'B'
AND g.freefield1 = 'V'
AND g.allocationtype = 'B' ) )
WHERE g.transtype = 'N'
AND ( i.itemcode = 'TESTARTIKEL'
OR i.itemcode = 'IQ7-60-2-INT' )
GROUP BY i.itemcode,
g.warehouse,
g.linkedline
) x where rowno=1 ;

You can use:
select *****Here the columns that you want to use****** from (****Your query****) anyName
In your case:
select *****Here the columns that you want to use****** from (
SELECT i.ItemCode, g.warehouse, SUM(g.aantal) AS Voorraad, MAX(CASE WHEN g.transtype = 'N' THEN g.sysmodified ELSE NULL END) AS LastDate
FROM dbo.gbkmut AS g INNER JOIN dbo.Items AS i
ON g.artcode = i.ItemCode AND g.reknr = i.GLAccountDistribution AND (
g.transtype = 'N' OR
(g.transtype = 'B' AND
g.transsubtype = 'B' AND
g.freefield1 NOT IN ('B', 'Q', 'W', 'K') AND
g.BlockItem = '0' AND
g.AllocationType = 'F') OR ( g.transtype = 'B' AND g.transsubtype = 'B' AND g.freefield1 = 'V' AND g.AllocationType = 'B'))
WHERE g.transtype = 'N' AND (i.ItemCode = 'TESTARTIKEL' OR i.ItemCode = 'IQ7-60-2-INT') GROUP BY i.ItemCode, g.warehouse, g.LinkedLine
) Name
