Primary index:  It works on unique indexes. The data should be unique and not null. Retrieve data from the database. Clustered Index:  Clustered Index. A clustered index defines the order in which data is physically stored in a table. Table data can be sorted in only way, therefore, there can be only one clustered index per table. In SQL Server, the primary key constraint automatically creates a clustered index on that particular column It works on unique and non-unique indexes. Retrieve data from the AOS. The advantages of having a cluster index are as follows: Search results are quicker when records are retrieved by the cluster index, especially if records are retrieved sequentially along the index.   Other indexes that use fields that are a part of the cluster index might use less data space.  Fewer files in the database; data is clustered in the same file as the clustering index. This reduces the space used on the disk and in the cache. ...
