Hi,
I have a column with DATE datatype and has data in it.
Based on this column, I would like to update another column that is of NUMBER datatype.
The data should be updated as follows:

source_column: 01-JAN-2013
target_column: 20130101 (YYYYMMDD format)

Could someone please suggest?

Thanks

Try this:

select to_number(to_char(trunc(source_column),'YYYYMMDD'))
from your_table;

(to see if you get the right values).

And if it looks OK, update like this:

update your_table
set target_column = to_number(to_char(trunc(source_column),'YYYYMMDD'));
