A view can be created from one or many tables which depends on the written SQL query to create a view.
Simply put, an index is a pointer to data in a table. A view also has rows and columns as they are in a real table in the database. Since filtered indexes weren’t introduced until SQL Server 2008, this can come in handy when you encounter older versions (I just finished a client project on SQL Server 2000, so you never know). Indexes are special data structures associated with tables or views that help speed up the query. This method is an extension of the earlier sys.indexes method. In SQL Server CREATE INDEX command creates a relational index on a table or view. Views, which are a type of virtual tables allow users to do the following − The dm_db_index_usage_stats DMV displays essential information about index usage, and it can be a useful tool in identifying unused SQL Server indexes. You can create a rowstore index before there is data in the table. (Remember that the index advice is a historical record and not a snapshot of the current system state. Indexed views work best for queries that aggregate many rows. When we insert single rows in the table, which is how many OLTP apps work, SQL is able to figure out which data is going to require updating the indexed view index. Remember, when we have an aggregate in the query, it adds the numbers together, so we need to have the GROUP BY clause.. Basically, when there’s a GROUP BY in a query, we need to group by everything that is in the select list except the aggregate. The fields in a view are fields from one or more real tables in the database. A view can contain all rows of a table or select rows from a table. Unless we defined indexed views, a view in SQL Server does not store a set of values in a database. This will be helpful to see the column names along with the index name. We got an aggregate in the SELECT statement followed by the GROUP BY clause. A view contains rows and columns, just like a real table. In this section, you will learn everything you need to know about indexes to come up with a good index … My understanding is that a view is really just a subquery, i.e., if I say SELECT * FROM myView, i'm really saying SELECT * FROM (myView's Query) It seems like the indexes on the underlying tables would be the ones that matter the most. Also called a rowstore index because it is either a clustered or nonclustered btree index. Right-click the Index Advisor entry naming the table you are interested in and click Table->**Work With->**Indexes. You can create a rowstore index before there is data in the table. Automatic statistics require a NOEXPAND hint SQL Server can create statistics automatically to assist with cardinality estimation and cost-based decision-making during query optimization. In SQL Server CREATE INDEX command creates a relational index on a table or view. Filtered indices are a special form of nonclustered indices, where the index is narrowed using a condition in the particular query. So i clearify that "you can not use AVG, MAX, MIN, STDEV, STDEVP, VAR, or VARP aggregate functions in select statement for a schema binded view ". Queries that don’t specifically use the indexed view can even benefit from the existence of the clustered index from the view.
