Re: multiple numbers in one statement

Is there any way to insert into table 100 integers from 1 to 100 in one
insert statement?
Now I have to use loop to insert numbers. I was wondering if there is the
simpler way.

WITH numbers(n) AS
SELECT row_number() OVER (ORDER BY object_id) FROM sys.columns
)
SELECT n FROM numbers WHERE n <= 100

The row_number function is handy for a lot of things.

If you want lots of numbers, you not have a good table to work from. Here
is a query for a million numbers:

CREATE TABLE Numbers (Number int NOT NULL PRIMARY KEY);
WITH digits (d) AS (
SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION
SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION
SELECT 7 UNION SELECT 8 UNION SELECT 9 UNION
SELECT 0)
INSERT Numbers (Number)
SELECT Number
FROM (SELECT i.d + ii.d * 10 + iii.d * 100 + iv.d * 1000 +
v.d * 10000 + vi.d * 100000 AS Number
FROM digits i
CROSS JOIN digits ii
CROSS JOIN digits iii
CROSS JOIN digits iv
CROSS JOIN digits v
CROSS JOIN digits vi) AS Numbers
WHERE Number > 0
