HI All!
This should be a simple one, but I'm having issues coming up with a solution.
I have the following dates Jan 2008-Dec 2012
(i.e. 200801
200802,
etc.)
stored into a table. When I run my query, I simply have 48 rows ( one row for each month). How can I get the 48 rows to repeat, say 100 times?
Thanks!!!:-)

HA! That was simple enough.

Is there a way to make it all one result set, rather than 100 sets. I really need it at least 600 times and don't want to copy and paste 600+ times.:-P

Not strictly T-SQL but its a useful feature.

Cross join to a table with the number of rows equal to the number of repetitions you need. Numbers tables are useful for that.

Sorry, can you elaborate a bit more. I'm still not having any luck.

That's cool. Would you mind posting your final code so others may learn how to do it? Thanks?

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Here is one way of doing it:

DROP TABLE #Temp

DECLARE @X int

SET @X = 1

CREATE TABLE #Temp (Phone varchar(17) null)

WHILE @X < 101

BEGIN

INSERT INTO #Temp(Phone) select Phone from People where Phone = '123-4567'

SET @X = @X + 1

END

select peop.* from People peop

LEFT JOIN #Temp on #Temp.Phone = peop.Phone

where Phone = '123-4567'

--DROP TABLE #Temp (don't forget to clean up)

That's very procedural. Why not do it faster, and more efficient:

select Phone

from People

cross join (select top 100 from sys.columns) as Multiplier;
