Return Multiple Identical Records

I need to return multiple records for each record in a table based on the numeric value of one of the columns.  I have this working in a separate sproc (example below) , but it is using non-numeric values to determine number of rows. I'm looking for a more mathy way to use the quantity column to determine the number of rows to return, so I don't have to have a hundred union alls.

Sample data is attached. The confirmeddrops field is the one that determines how many duplicates of the row to return.

	--Return multiple rows based on breakpoint/level.	
	INSERT INTO @Results(program,wAgin,mrkNbr,brand,ofln,bp,oflnAG,oflnCA,oflnCR,oflnGB,oflnTT,oflnWM)
	SELECT program,wAgin,mrkNbr,SUBSTRING(loc,3,2) Brand, SUBSTRING(fill,5,4) Ofln,bp,'','','','','',''
	FROM tbl_lsu
		SELECT 1 AS bp_repeater UNION ALL
		SELECT 2 WHERE bp IN ( 'D', 'T', 'Q' ) UNION ALL
		SELECT 4 WHERE bp IN ( 'Q' )
	) AS bp_repeater
	WHERE SUBSTRING(loc,3,2) = @Brand
	AND program = @Prog
	AND progYear = @Year
	AND Convert(int,SUBSTRING(fill,5,4)) BETWEEN @Ofln AND @LOfln

The simplest way to do this (and one of the most versatile ways to do a number of different tasks in SQL Server) is to make a tally table - just a table containing a sequence of numbers, of any size.

First, create the table:
CREATE TABLE tally (num int primary key clustered)

Open in new window

Then populate the table. Here is how I usually do this:
DECLARE @ct int, @num int, @max int
INSERT INTO tally (num) values (1);
INSERT INTO tally (num) values (2);

SET @ct = 2
WHILE @ct <= 12  -- this will be big enough for most uses - 2^12 entries
    SELECT @max = max(num) FROM tally

    INSERT INTO tally (num)
    SELECT num + @max
    FROM tally

    Set @ct = @ct + 1

Open in new window

Now, to use it to return multiple copies of your data, just JOIN to the tally table. Assuming a simple (value = number of rows) condition, a simple INNER JOIN would do:
INNER JOIN tally t
ON t.num BETWEEN 1 and x.value

The tally table suggestion above will certainly solve the specific question, but why are you needing this deliberate repetition?

It's for a Quality Control check application. Scan checks one by one with a timestamp on each check.

Thanks I'll give the tally a try.
