I want to delete the records from this table and I want retain only last 3 recent records for each userid.

Any help on this Appreciated.

SELECT @SQL = @SQL +[Text]
FROM @tblSQL
WHERE id <= @intCount
ORDER BY id

Sale{Cleant_name,Product}
eg:
Client_name | Product
a | 123
a | 321
b | 123
output must be in this pattern:
Client_name | product1 | product2
a | 123 | 321
b | 123

Thanks in advance

See, I knew this would kill performance. Use this for now. In couple of days I will update another version which I can assure you will be much faster than this.

But, I wonder, 14,000 records execution time is 4 minutes… That is worst than I expected.

What is your Server Specs ?

Thanks again for your help.

One Important assumption I made here was, First C_Rank Value for any C_ID would be ‘A’. If not, you have to modify script accordingly.

~IM.

I am sure there is a better way of doing this, but below script is the quiest way….

/*
THIS IS SETUP TABLE, WITH SOME SAMPLE DATA
*/
if exists (select 1 from tempdb.sys.objects where name like ‘#Temp_Table%’)
drop table #Temp_Table

create table #Temp_Table
(
C_ID int
, C_Rank char(1)
, Date datetime
, NewColumn int
)

insert into #Temp_Table
(
C_ID
, C_Rank
, Date
)
select 42, ‘A’, ’10/14/2010′
union all
select 42, ‘B’, ’10/26/2010′
union all
select 42, ‘B’, ’10/14/2010′
union all
select 42, ‘C’, ’10/26/2010′
union all
select 42, ‘A’,’02/16/2011′
union all
select 43, ‘A’, ’12/17/2010′
union all
select 44, ‘A’, ’07/28/2010′
union all
select 44, ‘B’, ’08/10/2010′
union all
select 44, ‘A’, ’01/11/2011′
union all
select 44, ‘B’, ’01/28/2011′
union all
select 44, ‘C’, ’10/14/2010′
union all
select 44, ‘D’, ’10/26/2010′

Your blog is very helpful. But i am stuck with something different. I have table having following columns.

C_ID C_ Rank NewColumn(Cycle) Date
42 A 1 October 14, 2010
42 B 1 October 26, 2010
42 A 2 February 16, 2011

43 A 1 December 17, 2010

44 A 1 July 28, 2010
44 B 1 August 10, 2010
44 A 2 January 11, 2011
44 B 2 January 28, 2011

45 A 1 July 30, 2010
45 B 1 August 9, 2010
45 B 1 September 24, 2010
45 A 2 April 5, 2011
45 B 2 April 26, 2011

Actually table has three columns(C_ID, C_rank, Date). I want to generate one more column called Cycle in such a way that for each C_ID, it should generate the number start from one and increment the number from next C_rank ‘A’ (a shown above).
I tried using row_number, but no luck.
May be some loop option till next C_Rank ‘A’ works.
This is urgent.
Any help is appreciated.

Thanks.

como faz qual formulas horario para turno? exemplo

hora — turno
6:15 — 1
9:00 — 1
15:50 — 2
23:05 — 3

I was hoping if you guys can point me to the right direction.

I do have the following table scenario

Columns: Year, Period, MonthToDate, YearToDate

Row1: 2010, 0, 100, 100
Row2: 2010, 3, 200, 300
Row3: 2010, 9, 300, 600

I was hoping to create a While script that will insert the missing periods (up to period 12), and then place 0 for the MonthToDate, while also making sure the YearToDate values are correct.

As such, I was hoping to get the following result set:

Columns: Year, Period, MonthToDate, YearToDate

Row1: 2010, 0, 100, 100
Row2: 2010, 1, 0, 100
Row3: 2010, 2, 0, 100
Row4: 2010, 3, 200, 300
Row5: 2010, 4, 0, 300
Row6: 2010, 5, 0, 300
Row7: 2010, 6, 0, 300
Row8: 2010, 7, 0, 300
Row9: 2010, 8, 0, 300
Row10: 2010, 9, 300, 600
Row11: 2010, 10, 0, 600
Row12: 2010, 11, 0, 600
Row13: 2010, 12, 0, 600

It looks like I would also need some grouping on the script.

Any ideas you have would be greatly appreciated.

Thank you for your time.

Regards,

Eric

Small Correction in SQL Statement, it should be Plus but not a comma,

Corrected SQL :
————————————-

Select AccountID
,SUM(ISNULL(InBytes,0)+ ISNULL(OutBytes,0) TotalUsage
From MyTable
Where Day Between @StartDate AND @EndDate
Group BY AccountID
