What is an index?

Answer Posted / mandar kavishwar

Indexes in databases are similar to indexes in books. In a
database,an index allows the database program to find data
in a table without
scanning the entire table.
There are two types of Index in MS-SQL.
1.Clustered
2.Non-Clustered
In MS-SQL Server 2005,
Only 1 Clustered & 249 Non-Clustered Possible.So (Total 250)
But in MS-SQL Server 2008,
Only 1 Clustered & 999 Non-Clustered Possible.(Total 1000)
