Isolating numbers from varchar field

SubbuMay 21 2007 — edited May 21 2007
Hi All,

My table contains a varchar2 field. It has both numeric entries and alpha numeric entires. Please suggest me a simple solution (cost effective) to isolate only the numeric value rows.

My table contain millions of record.
