One table can only one clustered index or primary key and
249 non-clustered index or unique key

Answer / raji

Indexes may be defined as unique or non-unique. A unique
index acts as a constraint on the table by preventing
identical rows in the index and thus, the original columns.

Answer / c.jagadish

In sqlserver we have two types of indexes (1) Clustered (2)
non clustered indexes.

Indexes may be simple index or composite index.

Index formed based on single column values is called simple
index

index formed based on multiple column values is called
composite index.

Default index is NON CLUSTERED INDEX

When a table contains a primary key column then sqlserver
automatically creates a unique clustered index.

Unique--- automatically creates a non clustered index

so for this reason PRIMARY KEY IS NOT EQUAL TO UNIQUE + NOT
NULL.
