SQL to generate a list of numbers from 1 to 100

Question

Using the DUAL table, how can I get a list of numbers from 1 to 100?

Answer 1

If you want your integers to be bound between two integers (i.e. start with something other than 1), you can use something like this:

with bnd as (select 4 lo, 9 hi from dual)
select (select lo from bnd) - 1 + level r
from dual
connect by level <= (select hi-lo from bnd);

It gives:

4
5
6
7
8

Answer 2

Do it the hard way. Use the awesome MODEL clause:

SELECT V
FROM DUAL
MODEL DIMENSION BY (0 R)
      MEASURES (0 V)
      RULES ITERATE (100) (
        V[ITERATION_NUMBER] = ITERATION_NUMBER + 1
      )
ORDER BY 1

Answer 3

Another interesting solution in ORACLE PL/SQL:

    SELECT LEVEL n
      FROM DUAL
CONNECT BY LEVEL <= 100;

Answer 4

You could use XMLTABLE:

SELECT rownum
FROM XMLTABLE('1 to 100');

-- alternatively(useful for generating range i.e. 10-20)
SELECT (COLUMN_VALUE).GETNUMBERVAL() AS NUM
FROM XMLTABLE('1 to 100');

Using GROUP BY CUBE:

SELECT ROWNUM
FROM (SELECT 1 AS c FROM dual GROUP BY CUBE(1,1,1,1,1,1,1) ) sub
WHERE ROWNUM <=100;
