Date conversion issue

Hi All,

I have an issue while converting the date datatype.

My source is 2013.05.12 

Target should be 20130512

I want only remove the dot from the field. data type is date in both source and target.

I applied to_date(to_char(2013.05.12,'YYYYMMDD'),'YYYYMMDD') but still i am getting the same output 2013.05.12 .

Expecting speed answer.

Thanks

Selvam
