what are the different types of views in sql server?
92043
There are 2 types of Views in SQL: Simple View and Complex View. Simple views can only contain a single base table. Complex views can be constructed on more than one base table. In particular, complex views can contain: join conditions, a group by clause, a order by clause.

SQL views are constructed from SELECT statements. According to the SQL-92, statements used to construct views cannot contain the WHERE clause. The SQL command SELECT is used to retrieve view instances. SQL views can be used to hide columns.

Views are used for security purposes because they provide encapsulation of the name of the table. Data is in the virtual table, not stored permanently. Views display only selected data. We can also use Sql Join s in the Select statement in deriving the data for the view.

In SQL, a view is a virtual table based on the result-set of an SQL statement. A view contains rows and columns, just like a real table. ... You can add SQL functions, WHERE, and JOIN statements to a view and present the data as if the data were coming from one single table.

In a database, a view is the result set of a stored query on the data, which the database users can query just as they would in a persistent database collection object. This pre-established query command is kept in the database dictionary. ... Views can join and simplify multiple tables into a single virtual table.

A view is a virtual table. A view consists of rows and columns just like a table. The difference between a view and a table is that views are definitions built on top of other tables (or views), and do not hold data themselves. If data is changing in the underlying table, the same change is reflected in the view.

The Oracle DBA views encapsulate the most important Oracle metadata with details about tables, indexes, the SGA and the physical storage. The best way to use the DBA views is to get the DBA reference poster where the important DBA views and columns are highlighted.

A materialized view is a database object that contains the results of a query. ... You can select data from a materialized view as you would from a table or view. In replication environments, the materialized views commonly created are primary key, rowid, object, and subquery materialized views.

A view is a saved T-SQL query in SQL Server. The view definition is stored by SQL Server so that it can be used as a virtual table to simplify queries and add a layer of security to your base tables; however, it does not take up any space in the database. In fact, a view really doesn't do anything until you query it.

When a join is used, I don't think the views information tied to that table is pulled in. For example, you won't be able to add relationships tied to that table. A relationship is a choice that the user can make on the view. They can choose to add the relationship (from the section on the right side of the view).

ANSI-standard SQL specifies five types of JOIN : INNER , LEFT OUTER , RIGHT OUTER , FULL OUTER and CROSS . As a special case, a table (base table, view, or joined table) can JOIN to itself in a self-Join.
