There are three types of indexes -.
Unique Index.
Unique indexing does not allow the field to have duplicate values if the column is unique indexed. This index can be applied automatically when primary key is defined.
Clustered Index.
Clustered index reorders the physical order of the table and search based on the key values. Each table can have only one clustered index.
NonClustered Index.
This type of Index does not alter the physical order of the table and maintains logical order of data. In this Each table can have 999 nonclustered indexes.
