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 a sql query  in seperate rows  I want this    1000  1001  1002  1003        1050

This completed for me in 36 seconds on our DEV server. Like Brian's answer, focusing on filtering to the range is important from within the query; a BETWEEN still tries to generate all the initial records prior to the lower bound even though it doesn't need them.

declare @s bigint = 10000000
    ,   @e bigint = 20000000

;WITH 
Z AS (SELECT 0 z FROM (VALUES (0),(1),(2),(3),(4),(5),(6),(7),(8),(9),(10),(11),(12),(13),(14),(15)) T(n)),
Y AS (SELECT 0 z FROM Z a, Z b, Z c, Z d, Z e, Z f, Z g, Z h, Z i, Z j, Z k, Z l, Z m, Z n, Z o, Z p),
N AS (SELECT ROW_NUMBER() OVER (PARTITION BY 0 ORDER BY z) n FROM Y)

SELECT TOP (1+@e-@s) @s + n - 1 FROM N

Note that ROW_NUMBER is a bigint, so we can't go over 2^^64 (==16^^16) generated records with any method that uses it. This query therefore respects the same upper limit on generated values.

Here are couple quite optimal and compatible solutions   USE master   declare  min as int     set  min   1000  declare  max as int     set  max   1050     --null returns all  --  Up to 256 - 2 048 rows depending on SQL Server version select  isnull  min 0  number number  as  number FROM    dbo spt values  AS  number WHERE   number  type                         P      --integers     and      max                            is null     --return all         or  isnull  min 0  number number     lt     max    --return up to max       order by    number    --  Up to 65 536 - 4 194 303 rows depending on SQL Server version select  isnull  min 0  value1 number  value2 number numberCount numbers   as  number FROM  dbo spt values            AS  value1   cross join  dbo spt values    AS  value2   cross join    --get the number of numbers  depends on version      select  sum 1   as  numbers     from    dbo spt values     where   spt values  type         P  --integers                                 as  numberCount WHERE   value1  type     P    --integers     and value2  type     P    --integers     and      max    is null     --return all         or  isnull  min 0  value1 number  value2 number numberCount numbers                   lt     max            --return up to max       order by    number

Update for SQL 2017 and later  If the sequence you desire is  lt  8k then this will work  Declare  start num int   1000      end num int   1050  Select  number     start num   ROW NUMBER   over  order by  Select null   from string split replicate      end num- start num-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 0x20000 as v  as bit17         cross join  select 0 as v union ALL select 0x40000 as v  as bit18         cross join  select 0 as v union ALL select 0x80000 as v  as bit19       intList     where  Ending -  Starting  lt  0x100000         and intList value between  Starting and  Ending

I know I m 4 years too late  but I stumbled upon yet another alternative answer to this problem  The issue for speed isn t just pre-filtering  but also preventing sorting  It s possible to force the join-order to execute in a manner that the Cartesian product actually counts up as a result of the join  Using slartidan s answer as a jump-off point       WITH x AS  SELECT n FROM  VALUES  0   1   2   3   4   5   6   7   8   9   v n   SELECT ones n   10 tens n   100 hundreds n   1000 thousands n FROM x ones      x tens       x hundreds        x thousands ORDER BY 1   If we know the range we want  we can specify it via  Upper and  Lower  By combining the join hint REMOTE along with TOP  we can calculate only the subset of values we want with nothing wasted   WITH x AS  SELECT n FROM  VALUES  0   1   2   3   4   5   6   7   8   9   v n   SELECT TOP  1  Upper- Lower   Lower   ones n   10 tens n   100 hundreds n   1000 thousands n FROM x thousands INNER REMOTE JOIN x hundreds on 1 1 INNER REMOTE JOIN x tens on 1 1 INNER REMOTE JOIN x ones on 1 1   The join hint REMOTE forces the optimizer to compare on the right side of the join first  By specifying each join as REMOTE from most to least significant value  the join itself will count upwards by one correctly  No need to filter with a WHERE  or sort with an ORDER BY   If you want to increase the range  you can continue to add additional joins with progressively higher orders of magnitude  so long as they re ordered from most to least significant in the FROM clause   Note that this is a query specific to SQL Server 2008 or higher

If you don t have a problem installing a CLR assembly in your server a good option is writing a table valued function in  NET  That way you can use a simple syntax  making it easy to join with other queries and as a bonus won t waste memory because the result is streamed   Create a project containing the following class   using System  using System Collections  using System Data  using System Data Sql  using System Data SqlTypes  using Microsoft SqlServer Server   namespace YourNamespace      public sealed class SequenceGenerator                SqlFunction FillRowMethodName    FillRow            public static IEnumerable Generate SqlInt32 start  SqlInt32 end                        int  start   start Value              int  end   end Value              for  int i    start  i  lt    end  i                    yield return i                     public static void FillRow Object obj  out int i                        i    int obj                     private SequenceGenerator                 Put the assembly somewhere on the server and run   USE db  CREATE ASSEMBLY SqlUtil FROM  c  path to assembly dll  WITH permission set Safe   CREATE FUNCTION  Seq   start int   end int   RETURNS TABLE i int  AS EXTERNAL NAME  SqlUtil   YourNamespace SequenceGenerator   Generate     Now you can run   select   from dbo seq 1  1000000

This only works for sequences as long as some application table has rows   Assume I want sequence from 1  100  and have application table dbo foo with column  of numeric or string type  foo bar   select  top 100 row number   over  order by dbo foo bar  as seq from dbo foo   Despite its presence in an order by clause  dbo foo bar does not have to have distinct or even non-null values   Of course  SQL Server 2012 has sequence objects  so there s a natural solution in that product

I recently wrote this inline table valued function to solve this very problem   It s not limited in range other than memory and storage   It accesses no tables so there s no need for disk reads or writes generally   It adds joins values exponentially on each iteration so it s very fast even for very large ranges   It creates ten million records in five seconds on my server   It also works with negative values   CREATE FUNCTION  dbo   fn ConsecutiveNumbers            start int       end  int   RETURNS TABLE  RETURN   select     x268435456 X       x16777216 X       x1048576 X       x65536 X       x4096 X       x256 X       x16 X       x1 X        start      X from  VALUES  0   1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   as x1 X  join  VALUES  0   16   32   48   64   80   96   112   128   144   160   176   192   208   224   240   as x16 X  on x1 X  lt    end- start and x16 X  lt    end- start join  VALUES  0   256   512   768   1024   1280   1536   1792   2048   2304   2560   2816   3072   3328   3584   3840   as x256 X  on x256 X  lt    end- start join  VALUES  0   4096   8192   12288   16384   20480   24576   28672   32768   36864   40960   45056   49152   53248   57344   61440   as x4096 X  on x4096 X  lt    end- start join  VALUES  0   65536   131072   196608   262144   327680   393216   458752   524288   589824   655360   720896   786432   851968   917504   983040   as x65536 X  on x65536 X  lt    end- start join  VALUES  0   1048576   2097152   3145728   4194304   5242880   6291456   7340032   8388608   9437184   10485760   11534336   12582912   13631488   14680064   15728640   as x1048576 X  on x1048576 X  lt    end- start join  VALUES  0   16777216   33554432   50331648   67108864   83886080   100663296   117440512   134217728   150994944   167772160   184549376   201326592   218103808   234881024   251658240   as x16777216 X  on x16777216 X  lt    end- start join  VALUES  0   268435456   536870912   805306368   1073741824   1342177280   1610612736   1879048192   as x268435456 X  on x268435456 X  lt    end- start WHERE  end  gt       x268435456 X       isnull x16777216 X  0        isnull x1048576 X  0        isnull x65536 X  0        isnull x4096 X  0        isnull x256 X  0        isnull x16 X  0        isnull x1 X  0         start  GO  SELECT X FROM fn ConsecutiveNumbers 5  500     It s handy for date and time ranges as well   SELECT DATEADD day X  0  DayX  FROM fn ConsecutiveNumbers datediff day 0  5 8 2015    datediff day 0  5 31 2015     SELECT DATEADD hour X  0  HourX  FROM fn ConsecutiveNumbers datediff hour 0  5 8 2015    datediff hour 0  5 8 2015 12 00 PM       You could use a cross apply join on it to split records based on values in the table   So for example to create a record for every minute on a time range in a table you could do something like   select TimeRanges StartTime      TimeRanges EndTime      DATEADD minute X  0  MinuteX FROM TimeRanges cross apply fn ConsecutiveNumbers datediff hour 0 TimeRanges StartTime            datediff hour 0 TimeRanges EndTime   ConsecutiveNumbers

This uses procedural code and a table-valued function  Slow  but easy and predictable   CREATE FUNCTION  dbo   Sequence    start int   end int  RETURNS  Result TABLE ID int  AS begin declare  i int  set  i    start  while  i  lt    end      begin         insert into  result values   i           set  i    i 1      end return  end   Usage   SELECT   FROM dbo Sequence  3 7   ID 3 4 5 6 7   It s a table  so you can use it in joins with other data  I most frequently use this function as the left side of a join against a GROUP BY hour  day etc to ensure a contiguous sequence of time values   SELECT DateAdd hh ID  2018-06-20 00 00 00   as HoursInTheDay FROM dbo Sequence  0 23     HoursInTheDay 2018-06-20 00 00 00 000 2018-06-20 01 00 00 000 2018-06-20 02 00 00 000 2018-06-20 03 00 00 000 2018-06-20 04 00 00 000         Performance is uninspiring  16 seconds for a million rows  but good enough for many purposes   SELECT count 1  FROM  dbo   Sequence       1000001    2000000  GO

Here is a generic and relatively fast solution that outputs integers from 1 to  n   It works with any positive integer of  n  very large numbers will cause arithmetic overflow  without needing to add or remove table joins  It doesn t require the use of system tables nor do you to change max recursions  declare  n int   10000    with d as  select   from  values  0   1   2   3   4   5   6   7   8   9   x  d    n as        select d x from d where d  gt  0 and d  lt    n     union all     select x   10   d from n  d where x   10   d  lt    n   select x from n   You can add an order by clause to sort the numbers

2 years later  but I found I had the same issue  Here is how I solved it   edited to include parameters   DECLARE  Start INT   End INT SET  Start   1000 SET  End   1050  SELECT  TOP   End -  Start 1  ROW NUMBER   OVER  ORDER BY S  object id     Start - 1   Numbers  FROM    sys all objects S WITH  NOLOCK

This will also do  DECLARE  startNum INT   1000  DECLARE  endNum INT   1050  INSERT  INTO dbo Numbers           Num                   SELECT  CASE WHEN MAX Num  IS NULL  THEN  startNum                      ELSE MAX Num    1                 END AS Num         FROM    dbo Numbers GO 51

Select non-persisted values with the VALUES keyword  Then use JOINs to generate lots and lots of combinations  can be extended to create hundreds of thousands of rows and beyond    SELECT ones n   10 tens n   100 hundreds n   1000 thousands n FROM  VALUES 0   1   2   3   4   5   6   7   8   9   ones n         VALUES 0   1   2   3   4   5   6   7   8   9   tens n         VALUES 0   1   2   3   4   5   6   7   8   9   hundreds n         VALUES 0   1   2   3   4   5   6   7   8   9   thousands n  WHERE ones n   10 tens n   100 hundreds n   1000 thousands n BETWEEN  userinput1 AND  userinput2 ORDER BY 1   Demo  A shorter alternative  that is not as easy to understand   WITH x AS  SELECT n FROM  VALUES  0   1   2   3   4   5   6   7   8   9   v n   SELECT ones n   10 tens n   100 hundreds n   1000 thousands n FROM x ones      x tens       x hundreds        x thousands ORDER BY 1   Demo

The best option I have used is as follows   DECLARE  min bigint   max bigint SELECT  Min 919859000000   Max 919859999999  SELECT TOP   Max- Min 1   Min-1 row number   over order by t1 number  as N FROM master  spt values t1      CROSS JOIN master  spt values t2   I have generated millions of records using this and it works perfect
