    An index is an on-disk structure associated with a table or view that speeds retrieval of rows from the table or view.

    An index contains keys built from one or more columns in the table or view.

  • How many clustered index in a table
  • Create clustered index in sql server
  • Clustered index example
  • Create clustered index on multiple columns in sql server

    • These keys are stored in a structure (B-tree) that enables SQL Server to find the row or rows associated with the key values quickly and efficiently.

    Note

    Documentation uses the term B-tree generally in reference to indexes.

    In rowstore indexes, the Database Engine implements a B+ tree. This does not apply to columnstore indexes or indexes on memory-optimized tables. For more information, see the SQL Server and Azure SQL index architecture and design guide.

    A table or view can contain the following types of indexes:

    • Clustered

      • Clustered indexes sort and store the data rows in the table or view based on their key values.

        These key values are the columns included in the index definition. There can be only one clustered index per table, because the
