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

The solution I've developed and used for quite some time now (riding some on the shared works of others) is slightly similar to at least one posted. It doesn't reference any tables and returns an unsorted range of up to 1048576 values (2^20) and can include negatives if desired. You can of course sort the result if necessary. It runs pretty quickly, especially on smaller ranges.

Select value from dbo.intRange(-500, 1500) order by value  -- returns 2001 values

create function dbo.intRange 
(   
    @Starting as int,
    @Ending as int
)
returns table
as
return (
    select value
    from (
        select @Starting +
            ( bit00.v | bit01.v | bit02.v | bit03.v
            | bit04.v | bit05.v | bit06.v | bit07.v
            | bit08.v | bit09.v | bit10.v | bit11.v
            | bit12.v | bit13.v | bit14.v | bit15.v
            | bit16.v | bit17.v | bit18.v | bit19.v
            ) as value
        from       (select 0 as v union ALL select 0x00001 as v) as bit00
        cross join (select 0 as v union ALL select 0x00002 as v) as bit01
        cross join (select 0 as v union ALL select 0x00004 as v) as bit02
        cross join (select 0 as v union ALL select 0x00008 as v) as bit03
        cross join (select 0 as v union ALL select 0x00010 as v) as bit04
        cross join (select 0 as v union ALL select 0x00020 as v) as bit05
        cross join (select 0 as v union ALL select 0x00040 as v) as bit06
        cross join (select 0 as v union ALL select 0x00080 as v) as bit07
        cross join (select 0 as v union ALL select 0x00100 as v) as bit08
        cross join (select 0 as v union ALL select 0x00200 as v) as bit09
        cross join (select 0 as v union ALL select 0x00400 as v) as bit10
        cross join (select 0 as v union ALL select 0x00800 as v) as bit11
        cross join (select 0 as v union ALL select 0x01000 as v) as bit12
        cross join (select 0 as v union ALL select 0x02000 as v) as bit13
        cross join (select 0 as v union ALL select 0x04000 as v) as bit14
        cross join (select 0 as v union ALL select 0x08000 as v) as bit15
        cross join (select 0 as v union ALL select 0x10000 as v) as bit16

        cross join (select 0 as v union ALL select 0x80000 as v) as bit19
    ) intList
    where @Ending - @Starting < 0x100000
        and intList.value between @Starting and @Ending
