Creating a list of numbers in TransactSQL
To create a simple list of numbers in an SQL table,
(from http://www.simple-talk.com/sql/t-sql-programming/faking-arrays-in-transact-sql/), the following TransactSQL does the job for a small number of rows (fewer than 32768)
WITH Nbrs ( n ) AS (
SELECT 1 UNION ALL
SELECT 1 + n FROM Nbrs WHERE n < 500 )
SELECT n FROM Nbrs
OPTION ( MAXRECURSION 500 )
Alternatively (for higher row counts):
declare @i int
declare @rows_to_insert int
set @i = 0
set @rows_to_insert = 1000
while @i < @rows_to_insert
begin
INSERT INTO #temp VALUES (@i)
set @i = @i + 1
end
