I have three tables:
1. Flat Discount
2. Promotion
3. weeklyorder
When i join these table and take union i got 2 row with same data but one different .. how to merge it to show only one row.
Query:
SELECT skuMaster.SKU,
(skuMaster.MinimumStock - COUNT(*)) as ReorderQuantity,
'LowInventory' as descp
FROM SKUMaster skuMaster
JOIN InventoryMaster inventoryMaster ON skuMaster.SKU = inventoryMaster.SKU
GROUP BY skuMaster.sku, skuMaster.MinimumStock, skuMaster.Name
HAVING COUNT(*) < skuMaster.MinimumStock
UNION
SELECT WeeklyOrderList.SKU,
WeeklyOrderList.Quantity as ReorderQuantity,
'NoPO' as descp
FROM WeeklyOrderList
WHERE WeeklyOrderList.POCGen = 'true'
result :
SKU ReorderQuantity descp
1 1 LowInventory
2 2 LowInventory
2 2 NoPO
6 5 LowInventory
here 2nd And 3rd are alomost same only description is different.
can we combine them and show only one row with descp as lowinventory and NOPO
SKU ReorderQuantity descp
1 1 LowInventory
2 2 LowInventory NoPo
6 5 LowInventory
same as above suppose we have table below
SKU ReorderQuantity
1 1
2 5
2 10
6 5
here output should be Max reorder quantity of same sku
Result:
SKU ReorderQuantity
1 1
2 10
6 5
;WITH CTE AS
(
SELECT skuMaster.SKU,
(skuMaster.MinimumStock - COUNT(*)) as ReorderQuantity,
'LowInventory' as descp
FROM SKUMaster skuMaster
JOIN InventoryMaster inventoryMaster ON skuMaster.SKU = inventoryMaster.SKU
GROUP BY skuMaster.sku, skuMaster.MinimumStock, skuMaster.Name
HAVING COUNT(*) < skuMaster.MinimumStock
UNION
SELECT WeeklyOrderList.SKU,
WeeklyOrderList.Quantity as ReorderQuantity,
'NoPO' as descp
FROM WeeklyOrderList
WHERE WeeklyOrderList.POCGen = 'true'
)
SELECT DISTINCT
a.SKU,
a.ReorderQuantity,
descp = STUFF((SELECT ', ' + b.descp
FROM CTE b
WHERE b.ReorderQuantity = a.ReorderQuantity
FOR XML PATH('')), 1, 2, '')
FROM CTE a
just an example for above output mentioned
DECLARE #t TABLE
(
SKU INT,
ReorderQuantity INT
)
INSERT INTO #t (SKU,ReorderQuantity)
VALUES (1,1), (2,5), (2,10), (6,5)
SELECT t.SKU,tt.Qty
FROM #t t
INNER JOIN (SELECT MAX(ReorderQuantity)as Qty, SKU
FROM #t
GROUP BY SKU) tt
ON tt.SKU = t.SKU
GROUP BY t.SKU,tt.Qty

I‘m new in learning TSQL and I‘m struggling getting the numbers that doesn‘t exist in my table each ID.
Example:
CustomerID Group
1 1
3 1
6 1
4 2
7 2
I wanna get the ID which does not exist and select them like this
CustomerID Group
2 1
4 1
5 1
5 2
6 2
....
..
The solution by usin a cte doesn‘t work well or inserting first the data and do a not exist where clause.
Any Ideas?
If you can live with ranges rather than a list with each one, then an efficient method uses lead():
select group_id, (customer_id + 1) as first_missing_customer_id,
(next_ci - 1) as last_missing_customer_id
from (select t.*,
lead(customer_id) over (partition by group_id order by customer_id) as next_ci
from t
) t
where next_ci <> customer_id + 1
Cross join 2 recursive CTEs to get all the possible combinations of [CustomerID] and [Group] and then LEFT join to the table:
declare #c int = (select max([CustomerID]) from tablename);
declare #g int = (select max([Group]) from tablename);
with
customers as (
select 1 as cust
union all
select cust + 1
from customers where cust < #c
),
groups as (
select 1 as gr
union all
select gr + 1
from groups where gr < #g
),
cte as (
select *
from customers cross join groups
)
select c.cust as [CustomerID], c.gr as [Group]
from cte c left join tablename t
on t.[CustomerID] = c.cust and t.[Group] = c.gr
where t.[CustomerID] is null
and c.cust > (select min([CustomerID]) from tablename where [Group] = c.gr)
and c.cust < (select max([CustomerID]) from tablename where [Group] = c.gr)
See the demo.
Results:
> CustomerID | Group
> ---------: | ----:
> 2 | 1
> 4 | 1
> 5 | 1
> 5 | 2
> 6 | 2
I have two tables:
1. indexes and quantity of indexes
2. indexes and quantity of indexes with specified boxcodes. Boxcode is a number of box, which box contains indexes.
1. input table 1
item_id quantity
1 10
2 15
3 5
1 5
1 5
2 5
3 5
sum:
1 - 20
2 - 20
3 - 10
2. input table 2
item_id quantity boxcode
1 3 abc
2 2 abc
1 8 def
3 10 ghi
1 9 ghi
2 9 def
2 8 ghi !!!!!!!
1 item_id once on 1 boxcode
I want to get result:
3. result
item_id quantity boxcodes
1 10 abc/3, def/7
2 15 abc/2, def/9, ghi/4
3 5 ghi/5
1 5 def/1, ghi/4
1 5 ghi/5
2 5 ghi/4 !!!!!!!!
3 5 ghi/5
Records from table 1 must be in the same order.
I have no idea how it can be done.
Any suggestion?
CREATE TABLE #input1
(
rownum int,
item_id int,
quantity int
)
CREATE TABLE #input2
(
item_id int,
quantity int,
boxcode varchar(10)
)
INSERT INTO #input1 VALUES (1,1,10)
INSERT INTO #input1 VALUES (2,2,15)
INSERT INTO #input1 VALUES (3,3,5)
INSERT INTO #input1 VALUES (4,1,5)
INSERT INTO #input1 VALUES (5,1,5)
INSERT INTO #input1 VALUES (6,2,5)
INSERT INTO #input1 VALUES (7,3,5)
INSERT INTO #input2 VALUES (1,3, 'abc')
INSERT INTO #input2 VALUES (2,2, 'abc')
INSERT INTO #input2 VALUES (1,8, 'def')
INSERT INTO #input2 VALUES (3,10, 'ghi')
INSERT INTO #input2 VALUES (1,9, 'ghi')
INSERT INTO #input2 VALUES (2,9, 'def')
INSERT INTO #input2 VALUES (2,8, 'ghi')
select * from #input1
select * from #input2
drop table #input1
drop table #input2
result
Thanks,
Weird, but it works:
;WITH rec1 AS (
SELECT rownum,
item_id,
1 as q,
1 as [Level],
quantity
from #input1
UNION ALL
SELECT r.rownum,
r.item_id,
1,
[Level] + 1,
i.quantity
FROM rec1 r
INNER JOIN #input1 i
ON r.rownum = i.rownum AND r.item_id = i.item_id
WHERE [Level] < i.quantity
), rec2 AS (
SELECT boxcode,
item_id,
1 as q,
1 as [Level],
quantity
from #input2
UNION ALL
SELECT r.boxcode,
r.item_id,
1,
[Level] + 1,
i.quantity
FROM rec2 r
INNER JOIN #input2 i
ON r.boxcode = i.boxcode AND r.item_id = i.item_id
WHERE [Level] < i.quantity
), cte1 AS (
SELECT *,
ROW_NUMBER() OVER (PARTITION BY item_id ORDER BY item_id, rownum) as rn
FROM rec1
), cte2 AS (
SELECT *,
ROW_NUMBER() OVER (PARTITION BY item_id ORDER BY item_id, boxcode) as rn
FROM rec2
), final AS (
SELECT c1.rownum,
c1.item_id,
c1.quantity,
c2.boxcode+'/'+CAST(SUM(c2.q) as nvarchar(10)) as boxcodes
FROM cte1 c1
INNER JOIN cte2 c2
ON c1.item_id = c2.item_id and c1.rn = c2.rn
GROUP BY c1.rownum, c1.item_id, c1.quantity, c2.boxcode
)
SELECT DISTINCT
f.rownum,
f.item_id,
f.quantity,
STUFF((
SELECT ', '+f1.boxcodes
FROM final f1
WHERE f1.rownum = f.rownum
AND f1.item_id = f.item_id
AND f1.quantity = f.quantity
FOR XML PATH('')
),1,2,'') boxcodes
FROM final f
Output for dataset you have provided:
rownum item_id quantity boxcodes
1 1 10 abc/3, def/7
2 2 15 abc/2, def/9, ghi/4
3 3 5 ghi/5
4 1 5 def/1, ghi/4
5 1 5 ghi/5
6 2 5 ghi/4
7 3 5 ghi/5
The main idea is to spread quantity in both tables for a small parts 1. Than add row number, then join and get result.
A solution (but it's totally based on gofr1's answer, to be honest !), to simplify a bit, would be to create a Numbers table, with as many numbers as you want.
CREATE TABLE Numbers(Number INT PRIMARY KEY);
INSERT Numbers
SELECT TOP 1000 ROW_NUMBER() OVER (ORDER BY name)
FROM sys.all_columns;
That would just avoid the 2 recursive CTEs.
You could then use the same logic as gofr1 :
with rec1 AS (
SELECT
ROW_NUMBER() OVER (PARTITION BY item_id ORDER BY item_id, rownum) as rn,
rownum,
item_id,
case when quantity = 0 then 0 else 1 end as q,
quantity
from #input1
join Numbers n on n.Number <= quantity
)
, rec2 AS (
SELECT
ROW_NUMBER() OVER (PARTITION BY item_id ORDER BY item_id, boxcode) as rn,
boxcode,
item_id,
case when quantity = 0 then 0 else 1 end as q,
quantity
from #input2
join Numbers n on n.Number <= quantity
),
final AS (
SELECT c1.rownum,
c1.item_id,
c1.quantity,
c2.boxcode+'/'+CAST(SUM(c2.q) as nvarchar(10)) as boxcodes
FROM rec1 c1
INNER JOIN rec2 c2
ON c1.item_id = c2.item_id and c1.rn = c2.rn
GROUP BY c1.rownum, c1.item_id, c1.quantity, c2.boxcode
),
stuffed as (
SELECT
distinct rownum,
f.item_id,
f.quantity,
STUFF((
SELECT ', '+f1.boxcodes
FROM final f1
WHERE f1.rownum = f.rownum
AND f1.item_id = f.item_id
AND f1.quantity = f.quantity
FOR XML PATH('')
),1,2,'') boxcodes
FROM final f
group by item_id, quantity, boxcodes, rownum)
select *
from stuffed
order by rownum
I have a table_1:
id custno
1 1
2 2
3 3
and a table_2:
id custno qty descr
1 1 10 a
2 1 7 b
3 2 4 c
4 3 7 d
5 1 5 e
6 1 5 f
When I run this query to show the minimum order quantities from every customer:
SELECT DISTINCT table_1.custno,table_2.qty,table_2.descr
FROM table_1
LEFT OUTER JOIN table_2
ON table_1.custno = table_2.custno AND qty = (SELECT MIN(qty) FROM table_2
WHERE table_2.custno = table_1.custno )
Then I get this result:
custno qty descr
1 5 e
1 5 f
2 4 c
3 7 d
Customer 1 appears twice each time with the same minimum qty (& a different description) but I only want to see customer 1 appear once. I don't care if that is the record with 'e' as a description or 'f' as a description.
First of all... I'm not sure why you need to include table_1 in the queries to begin with:
select custno, min(qty) as min_qty
from table_2
group by custno;
But just in case there is other information that you need that wasn't included in the question:
select table_1.custno, ifnull(min(qty),0) as min_qty
from table_1
left outer join table_2
on table_1.custno = table_2.custno
group by table_1.custno;
"Generic" SQL way:
SELECT table_1.custno,table_2.qty,table_2.descr
FROM table_1, table_2
WHERE table_2.id = (SELECT TOP 1 id
FROM table_2
WHERE custno = table_1.custno
ORDER BY qty )
SQL 2008 way (probably faster):
SELECT custno, qty, descr
FROM
(SELECT
custno,
qty,
descr,
ROW_NUMBER() OVER (PARTITION BY custno ORDER BY qty) RowNum
FROM table_2
) A
WHERE RowNum = 1
If you use SQL-Server you could use ROW_NUMBER and a CTE:
WITH CTE AS
(
SELECT table_1.custno,table_2.qty,table_2.descr,
RN = ROW_NUMBER() OVER ( PARTITION BY table_1.custno
Order By table_2.qty ASC)
FROM table_1
LEFT OUTER JOIN table_2
ON table_1.custno = table_2.custno
)
SELECT custno, qty,descr
FROM CTE
WHERE RN = 1

My table structure is below :
MyTable (ID Int, AccID1 Int, AccID2 Int, AccID3 int)
ID AccID1 AccID2 AccID3
---- -------- -------- --------
1 12 2 NULL
2 4 12 1
3 NULL NULL 5
4 7 NULL 1
I want to create indexed view with below output :
ID Level Value
---- ----- -------
1 1 12
1 2 2
2 1 4
2 2 12
2 3 1
3 3 5
4 1 7
4 3 1
EDIT :
My table is very huge and I want to have above output.
I can Get my query such as below :
Select ID,
Case StrLevel
When 'AccID1' Then 1
When 'AccID2' Then 2
Else 3
End AS [Level],
AccID as Value
From (
Select A.ID, A.AccID1, A.AccID2, A.AccID3
From MyTable A
)as p
UNPIVOT (AccID FOR [StrLevel] IN (AccID1, AccID2, AccID3)) AS unpvt
or
Select *
from (
select MyTable.ID,
num.n as [Level],
Case Num.n
When 1 Then MyTable.AccID1
When 2 Then MyTable.AccID2
Else MyTable.AccID3
End AS AccID
from myTable
cross join (select 1
union select 2
union select 3)Num(n)
)Z
Where Z.AccID IS NOT NULL
or
Select A.ID,
2 AS [Level],
A.AccID1 AS AccID
From MyTable A
Where A.AccID1 IS NOT NULL
Union
Select A.ID,
2 AS [Level],
A.AccID2
From MyTable A
Where A.AccID2 IS NOT NULL
Union
Select A.ID,
3 AS [Level],
A.AccID3
From MyTable A
Where A.AccID3 IS NOT NULL
But Above query is slow and I want to have indexed view to have better performance.
and in indexed view I can't use UNION or UNPIVOT or CROSS JOIN in indexed view.
What if you created a Numbers table to essentially do the work of your illegal CROSS JOIN?
Create Table Numbers (number INT NOT NULL PRIMARY KEY)
Go
Insert Numbers
Select top 30000 row_number() over (order by (select 1)) as rn
from sys.all_objects s1 cross join sys.all_objects s2
go
Create view v_unpivot with schemabinding
as
Select MyTable.ID,
n.number as [Level],
Case n.number
When 1 Then MyTable.AccID1
When 2 Then MyTable.AccID2
Else MyTable.AccID3
End AS AccID
From dbo.Mytable
Join dbo.Numbers n on n.number BETWEEN 1 AND 3
go
Create unique clustered index pk_v_unpivot on v_unpivot (ID, [Level])
go
Select
ID,
[Level],
AccID
From v_unpivot with (noexpand)
Where AccID IS NOT NULL
Order by ID, [Level]
The WHERE AccID IS NOT NULL must be part of the query because derived tables are not allowed in indexed views.
I need to run a sweepstakes script to get X amount of winners from a customers table. Each customer has N participations. The table looks like this
CUSTOMER-A 5
CUSTOMER-B 8
CUSTOMER-C 1
I can always script to have CUSTOMER-A,B and C inserted 5, 8 and 1 times respectively in a temp table and then select randomly using order by newid() but would like to know if there's a more elegant way to address this.
(Update: Added final query.)
(Update2: Added single query to avoid temp table.)
Here's the hard part using a recursive CTE plus the final query that shows "place".
Code
DECLARE #cust TABLE (
CustomerID int IDENTITY,
ParticipationCt int
)
DECLARE #list TABLE (
CustomerID int,
RowNumber int
)
INSERT INTO #cust (ParticipationCt) VALUES (5)
INSERT INTO #cust (ParticipationCt) VALUES (8)
INSERT INTO #cust (ParticipationCt) VALUES (1)
INSERT INTO #cust (ParticipationCt) VALUES (3)
INSERT INTO #cust (ParticipationCt) VALUES (4)
SELECT * FROM #cust
;WITH t AS (
SELECT
lvl = 1,
CustomerID,
ParticipationCt
FROM #Cust
UNION ALL
SELECT
lvl = lvl + 1,
CustomerID,
ParticipationCt
FROM t
WHERE lvl < ParticipationCt
)
INSERT INTO #list (CustomerID, RowNumber)
SELECT
CustomerID,
ROW_NUMBER() OVER (ORDER BY NEWID())
FROM t
--<< All rows
SELECT * FROM #list ORDER BY RowNumber
--<< All customers by "place"
SELECT
CustomerID,
ROW_NUMBER() OVER (ORDER BY MIN(RowNumber)) AS Place
FROM #list
GROUP BY CustomerID
Results

Single Query with No Temp Table
It is possible to get the answer with a single query that does not use a temp table. This works fine, but I personally like the temp table version better so you can validate the interim results.
Code (Single Query)
;WITH List AS (
SELECT
lvl = 1,
CustomerID,
ParticipationCt
FROM #Cust
UNION ALL
SELECT
lvl = lvl + 1,
CustomerID,
ParticipationCt
FROM List
WHERE lvl < ParticipationCt
),
RandomOrder AS (
SELECT
CustomerID,
ROW_NUMBER() OVER (ORDER BY NEWID()) AS RowNumber
FROM List
)
SELECT
CustomerID,
ROW_NUMBER() OVER (ORDER BY MIN(RowNumber)) AS Place
FROM RandomOrder
GROUP BY CustomerID
try this:
Select Top X CustomerId
From (Select CustomerId,
Rand(CustomerId) *
Count(*) /
(Select Count(*)
From Table) Sort
From Table
Group By CustomerId) Z
Order By Sort Desc
EDIT: abovbe assumed multiple rows per customer, one row per participation... Sorry, following assumes one row per customer, with column Participations holding number of participations for that customer.
Select Top 23 CustomerId
From ( Select CustomerId,
Participations - RAND(CustomerId) *
(Select SUM(Participations ) From customers) sort
from customers) Z
Order By sort desc
