Clustered vs Non-clustered Index - shikshaglbe

There are two types of indexes in SQL Server: clustered and nonclustered. A clustered index is a special type of index that reorders the way records in the table are physically stored. Therefore, a table can have only one clustered index. A nonclustered index is a special type of index in which the logical order of the index does not match the physical stored order of the rows on disk. A nonclustered index can be used to create multiple indexes on a table.A clustered index is a type of index that reorders the way records in the table are physically stored. Therefore, a table can have only one clustered index. A clustered index is useful when the order of the data in the table is important, such as when you use an ORDER BY clause in a query.A non-clustered index is a type of index that does not change the way records are stored in the table, but creates a separate structure that can be used to quickly look up data. A non-clustered index can be used by itself or as part of anotherindex, such as a clustered index. A table can have more than one non-clusteredindex.A clustered index is a type of index that orders the data rows in a table by their key values. A clustered index is thus a physical ordering of the table data. There can only be one clustered index per table, because the data rows can only be physically ordered in one way. A non-clustered index is a type of index that has a structure separate from the data rows. A non-clustered index contains the non-clustered index key values and each key value entry has a pointer to the data row that contains the key value.A clustered index is a type of database index that stores the data for a table in the order of the clustered index keys. A non-clustered index is a type of database index that stores the data for a table in a separate structure from the table data, but the index still points to the data in the table. Clustered indexes are more efficient than non-clustered indexes because they require less disk space and are faster to query.There are two types of indexing in SQL Server: clustered and non-clustered. A clustered index is a special type of index that reorders the way records in the table are physically stored. Therefore, there can only be one clustered index per table. A non-clustered index is a regular index that does not change the physical order of the table data. There can be multiple non-clustered indexes per table.A clustered index defines the physical order of data in a table. There can only be one clustered index per table, because the data can only be physically ordered in one way. A non-clustered index does not change the physical order of the data in the table, but creates a separate structure that can be used to look up data quickly. Non-clustered indexes have their own structure separate from the data rows.
