Answer / sanjay kumar dinda
Two types of indexes are there in SQL Server
1. Clustered Index
2. Non-Clustered Index
We can create only 1 Clustered index in a table as it re-
orders the data of the table
We can create upto 249 Non-Clustered index in a table...

Answer / sureshsamatham
There can be 1 or more indexes in a table.Indexes can be
clustered or non clustered. A clustered index stores data
rows in the table based on their key values. Each table can
have only one clustered index as the key values in the data
rows are unique and the index is built on the unique key
column. Non-Clustered indexes have structures that are
different from the data rows. A non clustered index key
value is used to point to data rows that contain the key
value. This value is known as row locator. The structure of
the row locator is determined on the basis of the type of
storage of the data pages. If the data page is stored as a
heap, a row locator becomes a pointer to a row. If the data
page is stored in a clustered table the row locator is a
clustered index key. Clustered and Non clustered indexes can
be unique and indexes are automatically maintained for a
table or view whenever the data table is modified.
