SQL Indexes are used in relational databases to quickly retrieve data. They are
similar to indexes at the end of the books whose purpose is to find a topic
quickly. SQL provides Create Index, Alter Index, and Drop Index commands that
are used to create a new index, update an existing index, and delete an index in
SQL Server.
Type of Indexes:
SQL Server supports two types of indexes:
1. Clustered Index
2. Non-Clustered Index.
1. Clustered Index: A B-Tree (computed) clustered index is the index that
will arrange the rows physically in the memory in sorted order. When the
Primary Key is created automatically the Clustered Index is created.
An advantage of a clustered index is that searching for a range of values
will be fast. A clustered index is internally maintained using a B-Tree data
structure leaf node of the b tree of clustered indexes that will contain the
table data; you can create only one clustered index for a table.
2. Non-clustered Index:
● When a Unique Key is created automatically, a Non-clustered Index is
created.
● A non-clustered index is an index that will not arrange the rows physically in
the memory in sorted order.
● An advantage of a non-clustered index is searching for the values that are in a
range will be fast.
● You can create a maximum of 999 non-clustered indexes on a table, which is
254 up to SQL Server 2005.
● A non-clustered index is also maintained in a B-Tree data structure but leaf
nodes of a B-Tree or non-clustered index contain the pointers to the pages
that contain the table data and not the table data directly.
