Lets suppose, we define a schema with no primary key but there is an attribute(s) with unique and not null constraints. Now default indexing i.e primary indexing is not possible here because of no primary key.  Now, at the time of Database design, If i write query for clustering index then is it necessary to input records in sorted order? or is there any other way possible to apply clustering index over a given database file?
