DATE displayed as 00000000

Hi,

I am starting into HANA SQL these days.....

I am trying following SQL -

select BNAME,BCODE,GLTGV,PASSCODE,UFLAG from "SAPQ12"."USR02";

This sql displays the date as 00000000. I tried TO_DATS(GLTGV) and result is same.

I tried TO_DATE(GLTGV) the result is '?'. I tried TO_DATS(GLTGV,'YYYYMMDD') and i get syntax error -

""invalid DATE, TIME or TIMESTAMP value: Error while parsing DATE/TIME at function to_date()".

Please help me in resolving one of the simplest issue.

Regards,

SS
