> Druid time expressions return numeric values in form of ms (instead of
> formatted timestamp). Because of this expressions/function which expects its
> argument as string type ended up returning different values for time
> expressions input.
> e.g.
> {code}
> SELECT SUBSTRING(to_date(datetime0),4) FROM tableau_orc.calcs;
> | 4-07-25 |
> SELECT SUBSTRING(to_date(datetime0),4) FROM druid_tableau.calcs;
> | 0022400000 |
> SELECT CONCAT(to_date(datetime0),' 00:00:00') FROM tableau_orc.calcs;
> | 2004-07-17 00:00:00 |
> SELECT CONCAT(to_date(datetime0),' 00:00:00') FROM druid_tableau.calcs;
> | 1090454400000 00:00:00 |
> {code}
> Druid needs explicit cast to make this work
