3 Shoes>Air>Jordan 2 Active

Hope you might help thanks ;)

Thanks for the article. It solved my problem

I want to make columns in a table like below:

Id Column1 Column2 Column3
1 5 5 => Same as Column1 5 => Same as Column2
2 2 12 => column1 current + column2.prev + column3.previous = 2+5+5 17 => column2.current + column3.prev = 12+5
3 3 32 => 3+12+17

easier way to see:

Id Column1 Column2 Column3
1 5 5 => Same as Column1 5 => Same as Column2
2 2 12 => 2+5+5 17 => 12+5
3 3 32 => 3+12+17 49 => 32+17

I am looking forward any answer and it will be appreciated. Thank you in advance

I have small doubt. The results from the above query and for the below query were same.

Then why i have to use CTE. Can you explain? Actually, i am the beginner for CTE’s.

select ProductMaster.Product_ID,
ProductMaster.ProductName,
Genre.GenreName,
ProductMaster.Price
from ProductMaster PM
Inner Join Product_Genre P_G on PM.Product_Id = P_G.Productid
Inner Join Genre G On G.Genre_Id = P_G.Genre_Id

Waiting for your reply,

Thanks & Regards

Is there any level for recursive CTE? How many levels we can go?

Please reply.

Thanks
Anand

for eg. if customer name, add store in one table then same customer phone no. in phone table.
so if customer name,add and phone no. are twise delete the record.

thanx madhivanan for the support

waiting for result

WITH dup(t1_name,t2_name,t3_name,duplicount)
AS(SELECT t1.t1_name,t2.t2_name,t3.t3_name
ROW_NUM() OVER(PARTITION_BY t1.t1_name,t2.t2_name,t3.t3_name ORDER BY t1.t1_name)AS duplicount from table1 t1
inner join table2 t2
on t1.t1_id=t2.t1_id
inner join table3 t3
on t1.t1_id=t3.t1_id)
delete from dup

above is the example plz reply as soon as posible

plz replay

tblParent
———
parentid(PK), parentname, address, age

tblMembers
———-
membername, age, sex, parentid(FK)

——————————-
My report should show like this:

Thanks for reply. i solved the issue in different way since i have 2million records..

with ctetbl1
as(
select affinityNumber from tbl
group by ID having COUNT(*)>1),
cteTemp
as(
select *
from tbl where AffinityNumber not in(select id from ctetbl1 where ID =’2′)
select * from cte temp

Thanks

You can use this solution, if you are using SQL 2005 and above.

I have used ROW_Number to identify if it is duplicate or not and get output as you want.

DECLARE @table TABLE(IDNO INT, Code INT)
INSERT INTO @table(IDNo, Code)
SELECT 1234, 1
UNION
SELECT 3456,1
UNION
SELECT 2345, 2
UNION
SELECT 1456, 2
UNION
SELECT 1234, 2
UNION
SELECT 2345, 1
UNION
SELECT 1456, 1
UNION
SELECT 2806, 2

;with cte as (
SELECT ROW_NUMBER() OVER(PARTITION BY IDNo ORDER BY Code) AS RowID,
IDNO,
Code
FROM @table
)
SELECT IDNO,
Code
FROM cte
WHERE RowID = 1

How’s this?

WITH
Data(IDNo, code)
AS
(
SELECT 1234, 1 UNION ALL
SELECT 3456, 1 UNION ALL
SELECT 2345, 2 UNION ALL
SELECT 1456, 2 UNION ALL
SELECT 1234, 2 UNION ALL
SELECT 2345, 1 UNION ALL
SELECT 1456, 1 UNION ALL
SELECT 2806, 2
)
SELECT
IDNo,
MIN(code)
FROM
Data
GROUP BY
IDNo;
