SQL database in Microsoft Fabric 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. These keys are stored in a structure (B-tree) that...
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 ...
Can be used in range queries. If the clustered index is not created with the UNIQUE property, the Database Engine automatically adds a 4-byte uniqueifier column to the table. When it is required, the Database Engine automatically adds a uniqueifier value to a row to make each key unique...
A clustered index on the range column avoids sorting the entire heap. Do not use a heap when there are no nonclustered indexes and the table is large. The only application for this design is to return the entire table content without any specified order. In a heap, Database Engine reads...
