How the mapped don, when there is no "column" attribute in <one-to-one> tag?

for <one-to-one> mapping, no column should be specified because, one-to-one generates join query on the ""OID"" attributes of 2 tables. That is why people called it one-to-one.
If you need to specify, column name, then it means that is many-to-one relation. Use many-to-one

You can use property-ref to specifiy a relation to a foreign key.
