All,
Anyboyd would like to share how easy to check the field which is string but
only 1 or 1.0 or 2.1 such data can be entered.
I could do it if I put the data field as number(10,1) something, but it can
not be retrieved from the perl script.
So I put the data field as varchar2 (oracle db), and now I need to validate
the data entry in the user interface.
User can not put string 'a', or 'a.a' .
Thanks,
Carol
