I'd like to use the generate series function in redshift, but have not been successful.
The redshift documentation says it's not supported. The following code does work:
select *
from generate_series(1,10,1)
outputs:
1
2
3
...
10
I'd like to do the same with dates. I've tried a number of variations, including:
select *
from generate_series(date('2008-10-01'),date('2008-10-10 00:00:00'),1)
kicks out:
ERROR: function generate_series(date, date, integer) does not exist
Hint: No function matches the given name and argument types.
You may need to add explicit type casts. [SQL State=42883]
Also tried:
select *
from generate_series('2008-10-01 00:00:00'::timestamp,
'2008-10-10 00:00:00'::timestamp,'1 day')
And tried:
select *
from generate_series(cast('2008-10-01 00:00:00' as datetime),
cast('2008-10-10 00:00:00' as datetime),'1 day')
both kick out:
ERROR: function generate_series(timestamp without time zone, timestamp without time zone, "unknown") does not exist
Hint: No function matches the given name and argument types.
You may need to add explicit type casts. [SQL State=42883]
If not looks like I'll use this code from another post:
SELECT to_char(DATE '2008-01-01'
+ (interval '1 month' * generate_series(0,57)), 'YYYY-MM-DD') AS ym
