What Is The Difference Between Sql Server 2000 Clustered And Nonclustered Indexes? |
|
Answer» With a clustered INDEX, the data are STORED in the bottom level of the index and in the same order as that index. With a nonclustered index, the bottom level of an index does not contain data; it contains pointers to the data. For data RETRIEVAL, clustered INDEXES are FASTER than nonclustered indexes. With a clustered index, the data are stored in the bottom level of the index and in the same order as that index. With a nonclustered index, the bottom level of an index does not contain data; it contains pointers to the data. For data retrieval, clustered indexes are faster than nonclustered indexes. |
