One to One relation in sql
712833Jul 20 2009 — edited Jul 21 2009Hi , I have some confusion in understanding One to One Mapping .
As per the Theory
One-to-one relationships occur when there is exactly one record in the first table that corresponds to exactly one record in the related table.
But can anybody Please let me know actually in what case such a requirement comes and how it will be useful
.
Thanks in advance .
