To focus, simplify, and customize the perception each user has of the database. The replication of updates made by using the view is the same as when tables are replicated in two different databases: With the CHECK constraint definitions, the query processor maps the distribution of key values across the member tables. Therefore, there is no need to update Index statistics after you rebuild all your indexes, but you do need to update column statistics. The view could be created for the person in charge of tracking work anniversaries but without giving this person access to all the data in these tables. Rather than a blanket update to all statistics, or statistics where one row has changed, I prefer to update statistics that are outdated based on the amount of data that has changed. In that case, if you are running SQL Server and below, you want to update Column statistics only. Address a ON a. A partitioned view on Server1 is defined in the following way: As a security mechanism by allowing users to access data through the view, without granting the users permissions to directly access the underlying base tables. Additional Conditions for Distributed Partitioned Views For distributed partitioned views when one or more member tables are remote , the following additional conditions apply: There is no other difference between these packages. Updatable Views You can modify the data of an underlying base table through a view, as long as the following conditions are true: When a view is created, information about the view is stored in the following catalog views: The columns being modified in the view must directly reference the underlying data in the table columns. The data from this view comes from the HumanResources. If one or more of the member tables are remote, the view is called distributed partitioned view, and additional conditions apply. Encrypts the entries in sys. A view does not have to be a simple subset of the rows and columns of one particular table. In SQL Server you can configure the Rebuild Index task so that it only rebuilds an index if a certain level of fragmentation exists. Using built-in functions within a view The following example shows a view definition that includes a built-in function. Therefore, the corresponding columns in the same ordinal position in the select list in the local tables must also be of type money. A view can have a maximum of 1, columns. All member tables in the view should have the same ANSI padding setting. NET 4, there is no need to have both enabled. Any columns in remote tables of type smallmoney that are referenced in a partitioned view are mapped as money. The data provides name and hire date information for the employees of Adventure Works Cycles.

When you run the Rebuild Index task in SQL Server , you rebuild all indexes, and when you rebuild an index, its statistic is updated with a fullscan. These original settings are used to parse the view when the view is used. Corresponding columns in the same ordinal position in the select list in the local tables must be smalldatetime. But what I see most often is that someone configures the Rebuild Index task, and then has the Update Statistics task as the next step. If one or more of the member tables are remote, the view is called distributed partitioned view, and additional conditions apply. If a new table or view is created and the table structure does not change from the previous base table to replace the one dropped, the view again becomes usable. SQL Server Express with database engine only can work with either. This trigger lets the user specify the set of actions that must happen to process the data modification statement. To meet the conditions of the partitioned view, there should be only one partitioning constraint on the partitioning column. This is a bit more complicated in SQL Server When querying through a view, the Database Engine checks to make sure that all the database objects referenced anywhere in the statement exist and that they are valid in the context of the statement, and that data modification statements do not violate any data integrity rules. When the member tables and partitioned view definition are in place, the SQL Server query optimizer builds intelligent plans that use queries efficiently to access data from member tables.
