I am just using SYSDATE as an example only since SYSDATE can never be
'000000'. In my case I have the following syntax to retrieve from a
table:


SQL> select decode(bill_begin_date,'000000',null,TO_DATE
(bill_begin_date, 'YYYYMM')) from TEMP_DETERMINATION;

DECODE(BI
---------







01-JUL-10
01-AUG-10



DECODE(BI
---------




01-AUG-10
01-SEP-10
