The looping query pasted below works fine in updating ‘hour’ in a date time column using NTILE().

+++++++++++++++++++
DECLARE @loop int
DECLARE @inc int

SET @inc=1
WHILE (@inc<=24)

BEGIN

;with up AS
(
SELECT salesorderdetailid,ntile(24) OVER (order by productid ) as ntile24
from sales.salesorderdetail
)
UPDATE sales.salesorderdetail
SET modifieddate=DATEADD(hh,@inc,modifieddate)
from sales.salesorderdetail
where salesorderdetailid in
(
select salesorderdetailid from up
where NTILe24 =@inc
)
PRINT @inc
SET @inc=@inc+1
END

–select * from sales.salesorderdetail tablesample (1000 rows)

+++++++++++++++++++

Is there any simplest way to solve this problem?
OR
If the query can be modified without using CTE?

Kindly suggest how to increase the query performance when handling these situations.

Thanks,

here i know how many attribute names are there so i can use cases here to update.

UPDATE CORE.MasterAttr
SET AttributeValue = (
CASE AttributeName
WHEN ‘DESCRIPTION’ THEN ‘Barge’
WHEN ‘SAP_MODE’ THEN ’01′
WHEN ‘MODE_CODE’ THEN ‘B’
END
) WHERE MasterId=1

but in real scenario i dont know how many attribute name will be available.
so i need to write storedprocedure .the input values will come from c#.
suppose for master id 2 i can have 12 attribute names and i have to update attribute vales for those attribute names.
if we give give masterid 4 and we can get 15 attribute names etc.

so how can we dynamically loop it and write stored procedure sir.it will really helps me alot.can u please help me on this.

i have doubt when i use the variables i and n as integer type ,A is printed 11
times
declare @i varchar(10)
declare @n varchar(10)
set @i=0
set @n=10
while(@i<=@n)
BEGIN
PRINT 'A'
set @i=@i+1
END

when i use the variables i and n as varchar ,A is printed twice can you please tell me the reason y this could be like this

–insert into #calender (string,dat)
select distinct substring (CCAL_Available_Days
,@counter,1), dateadd (day,@counter,'2012-07-28 00:00:00.000') date from dbo.CCALCalend
where CCAL_Year = '2012'
set @counter = @counter+1
–select * from #calender

end
drop table #calender
i am getting the error
The column "string" cannot be modified because it is either a computed column or is the result of a UNION operator.
can you please help

ex:
function emp()

str=”select * from employ”
set rs=conn.execute(str)

do while rs.eof=false

for i= 1 to 6

if sex=’m’ then

update status=’male’ where empcode=” & rs!emocode & ”

else

update status=’female’ where empcode=” & rs!emocode & ”

next

loop

end function

example To Delete All Products

and if 1 product record has dependencies

For each Product record, there is a record also in Product Inventory table

DECLARE
cursor c1 is
SELECT
ID AS i_PRODUCTID,
FROM PRODUCT
ORDER BY ID ASC;

BEGIN
FOR DELETEPRODUCTRECORD in c1
LOOP
DELETE FROM PRODUCT_INVENTORY WHERE PRODUCTID = DELETEPRODUCTRECORD .i_PRODUCTID;

DELETE FROM PRODUCT WHERE ID = DELETEPRODUCTRECORD .i_PRODUCTID;

END LOOP;

END;

==

In terms of performance and simplicity, this is the best method i have seen

Thank you

SELECT a.ticketno, a.mkrdt
FROM Tbl_Newtagg1 a, (SELECT TicketNo, min(mkrdt) AS StartDate FROM Tbl_Newtagg1 GROUP BY TicketNo) b
WHERE a.TicketNo = b.TicketNo AND a.mkrdt =b.startdate

–but it lists every ticket n its startdate only once.. plz help.. Thanks in advance

Tab:

col1 Key col2 startdate enddate
1 10 100 20111215 29991231
1 10 100 20111220 20111225
1 10 100 20111215 29991231
1 10 100 20111215 29991231

I want output as

col1 Key col2 startdate enddate
1 10 100 20111215 20111219
1 10 100 20111220 20111225
1 10 100 20111215 20111224
1 10 100 20111225 29991231

i think need to write a loop which will update the endate properly.

Please help…
