How to generate a range of numbers between two numbers?

Question

I have two numbers as input from the user, like for example 1000 and 1050.

How do I generate the numbers between these two numbers, using

Answer 1

This is what I do, it's pretty fast and flexible and not a lot of code.

DECLARE @count  int =   65536;
DECLARE @start  int =   11;
DECLARE @xml    xml =   REPLICATE(CAST('' AS nvarchar(max)), @count);

; WITH GenerateNumbers(Num) AS
(
    SELECT  ROW_NUMBER() OVER (ORDER BY @count) + @start - 1
    FROM    @xml.nodes('/x') X(T)
)
SELECT  Num
FROM    GenerateNumbers;

Note that (ORDER BY @count) is a dummy. It doesn't do anything but ROW_NUMBER() requires an ORDER BY.

Edit: I realized that the original question was to get a range from x to y. My script can be modified like this to get a range:

DECLARE @start  int =   5;
DECLARE @end    int =   21;
DECLARE @xml    xml =   REPLICATE(CAST('' AS nvarchar(max)), @end - @start + 1);

; WITH GenerateNumbers(Num) AS
(
    SELECT  ROW_NUMBER() OVER (ORDER BY @end) + @start - 1
    FROM    @xml.nodes('/x') X(T)
)
SELECT  Num
FROM    GenerateNumbers;
