If the table has a clustered index, the column or columns defined in the clustered index are automatically appended to the end of each nonclustered index on the table. Nonclustered Index Architecture Nonclustered indexes have the same B-tree structure as clustered indexes, except for the following significant differences: Column Considerations Consider columns that have one or more of these attributes: By doing this the objective of the index will be clear.

NET makes writing and deploying. Wide keys Wide keys are a composite of several columns or several large-size columns. Index maintenance may increase the time that it takes to perform modifications, inserts, updates, or deletes, to the underlying table or indexed view.

Developers do not usually generate dynamic SQL inside stored procedures. The resulting index will be smaller and cost less to maintain than a full-table nonclustered index defined on the same key columns.

Its been discussed over and over and over again.

Depending on the data types in the clustered index, each clustered index structure will have one or more allocation units in which to store and manage the data for a specific partition. Increase the length of varchar, nvarchar, or varbinary columns. After the query optimizer finds all entries in the index, it can go directly to the exact page and row to retrieve the data.

Use of Stored Procedures Option 3: White List Input Validation Option 4: Our binary releases are now all built with bit IDs by default.

Nonkey columns can only be defined on nonclustered indexes on tables or indexed views. This is faster as there is no intention of remembering things later. You might be tempted to use a single.

Similarly, if a filtered index contains only the frequently affected data, the smaller size of the index reduces the cost of updating the statistics. Note that they can still load older indexes with bit IDs, but that support will eventually be removed.

Use Included Columns to Extend Nonclustered Indexes You can extend the functionality of nonclustered indexes by adding nonkey columns to the leaf level of the nonclustered index. Partitions Across Multiple Filegroups You can also consider partitioning clustered and nonclustered indexes across multiple filegroups.

We recommend using the extended query syntax instead. Even if your database is SBCS likely for legacy reasons too, eh? For example, assume that you want to design an index to cover the following query.
