Numeric or Alphanumeric datatype
Hi,
In a table,I've a column named EMPID,now i wants to say making EMPID as Numeric datatype has more advantage than making it as Alphanumeric datatype.I've studied somewhere,there will be improvement in performance by using Numeric type than Alphanumeric type,thats why i'm asking it.
What are the possible reasons can i say for it?
Please anyone help me in clearing this doubt.
Thanks,
Malru
