Dear All,

I am facing a problem after migration DB from SQL to ORACLE.
There is a function ISNULL() supported by SQL but in ORACLE it is NVL().
But is there any way to use ISNULL in ORACLE without changing it's to NVL.
Please guide me or is there any DATA TYPE available in ORACLE that support all other data types(exp. char,varchar2,n umber date,etc...)
