Therefore, only one clustered index can be created on a given database table. Clustered indices can greatly increase overall speed of retrieval, but usually only where the data is accessed sequentially in the same or reverse order of the clustered index, or when a range of items is selected. An index is clustered if the order of the data records is the same as or close to the order of the index data entries In an unclustered index, the order of the data records and the order of the Clustered Index | Cs186 Wiki | Fandom clustered index (plural clustered indices or clustered indexes) (databases) a type of database index that physically sorts the data in a table on the disk to match the criteria specified by the index.

The key difference between clustered indexes and non clustered indexes is that the leaf level of the clustered index is the table. This has two implications. The rows on the clustered index leaf pages always contains something for each of the columns in the table (either the value, or a pointer to the actual value). A clustered index is a type of index where the table records are physically re-ordered to match the index. Clustered indexes are efficient on columns that are searched for a range of values. After the row with first value is found using a clustered index, rows with subsequent index values are guaranteed 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 are the columns included in the index definition. There can be only one clustered index per table, because the data rows themselves can be stored in only one order.

It is like a  11 Jan 2012 Maximizing the potential for elimination can require careful design, including a dependency on the clustered index order at the time the 

The Clustered index is basically used to order the rows in a table. A table can have only one clustered index because the rows in a table can be sorted in only one order, but there are ways to create a composite clustered index.
