I want to run a loop for exact number of times.

if i pass days increment : 30 days and create 3 records. and will give a date as reference.

for example the date is todays date:(041107)

i need to run a loop 3 times,

*****************************************
1st record: will be 04/11/07 + 30 days

2nd records: will be 04/11/07 + 60 days

3rd record: will be 04/11/07 + 90 days

********************************************

please i am very sorry if i am confusing you, the user will have a form, on the form he will choose a record as a reference that record is an existing record and will have a duedate. that duedate will be taken as reference date. and then the user choose increment number of days , in my above example i chose 30 days and for number new records to be created for that i chose as 3 records.

the loop should run only for 3 times and foreach record it should incrment 30 days for the existing records duedate.

Please is it possible in the stored procedure.

**********************************************
insert into tbl_expedite(due_date)
select due_date+30 from tbl_copyfromExpedite

**************************************************

Thank you very much for the information....

Declare @dt datetime,
@i int,
@d int

Select @dt = getdate(),
@i = 3,
@d = 30

Select dateadd ( dd, number * @d, @dt), number * @d
From master..spt_values
where type = 'p'
and number <= @i
and number <> 0

In the above ex @i is no. of times u want to loop, @d is no. of days u want to increment
@dt is u r date column.
in master..sptvalues u ll get 1-256 numbers.

what is the max number of records you will be expecting ? If it is typically small, you can just cross join to a derived table as follows. If you are looking at a large number of records, then make use of F_TABLE_NUMBER_RANGE here http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=47685


insert into tbl_expedite(due_date)
select 	dateadd(day, 30 * n, d.due_date)
from 	tbl_copyfromExpedite d
	cross join
	(
		select	n = 1 union all select n = 2 union all select n = 3 union all select n = 4 union all select n = 5
	) n
where	n <= 3

Hello Khtan,
The numbers are not going to be fixed, it will be dynamic. it can be 3 or 4 or may be 10
incrementing can be 1 day or 7 days or 30 days or 180 days or 365 days.
Can i use your example in that case. Thank you very much..

Yes. You still can. If the max number of records that you going to have is 10, just add on the "union all select n = 6" etc up to 10.

change this part to variable

select 	dateadd(day, @days * n, d.due_date)
