amazon web services - sequence number generation function in AWS redshift

Question

Is there a sequence number generation function in redshift ? Or a function that takes combination of values and gives out a numerical hash key ?

Answer 1

Here is another way to generate 1 million numbers

with seq_0_9 as (
select 0 as num
union all select 1 as num
union all select 2 as num
union all select 3 as num
union all select 4 as num
union all select 5 as num
union all select 6 as num
union all select 7 as num
union all select 8 as num
union all select 9 as num
), seq_0_999 as (
select a.num + b.num * 10 + c.num * 100 as num
from seq_0_9 a, seq_0_9 b, seq_0_9 c
)
select a.num + b.num * 1000 as num
from seq_0_999 a, seq_0_999 b
order by num
