Difference between primary key and unique key ?
Answer Posted / manoj routh
Both primary key and unique enforce uniqueness of the column
on which they are defined. But by default primary key
creates a clustered index on the column, where are unique
creates a nonclustered index by default. Another major
difference is that, primary key doesn't allow NULLs, but
unique key allows one NULL only.
