Difference between Primary & Cluster index AX


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.

The disadvantages of having a cluster index are as follows:

  • It takes longer to update records (but only when the fields in the clustering index are changed).
  • More data space might be used for other indexes that use fields that are not part of the cluster index if the clustering index is wider than approximately 20 characters).
