generate_series() method fails in Redshift

Question

When I run the SQL Query:

 select generate_series(0,g)
 from ( select date(date1) - date(date2) as g from mytable ;

It returns an error:

Answer 1

This works here (pg-9.3.3) Maybe your issue is just the result of a Redshift-"feature"?

CREATE TABLE mytable
        ( date1 timestamp
        , date2 timestamp
        );
INSERT INTO mytable(date1,date2) VALUES
( '2014-03-30 12:00:00' , '2014-04-01 12:00:00' );

SELECT  generate_series(0, ss.g) FROM
   ( SELECT date(date2) - date(date1) AS g
     FROM mytable
   ) ss ;
