You can reference a materialized view in your code much like a real table. Materialized View: Unlike a view, a materialized view has a concrete existance, in the sence that the tables are pre-joined and aggreations made and the results of the query are stored on disk. The following is an example of an Oracle materialized view on prebuilt table with an ON COMMIT refresh: A complete refresh occurs when the Oracle materialized view is initially defined, unless it references a prebuilt table, and a complete refresh may be requested at any time during the life of the Oracle materialized view. When accessing a materialized view, you are accessing the pre-computed results. This process is called a complete refresh. The Overflow Blog Podcast 297: All … Materialized views are a really useful performance feature, allowing you to pre-calcuate joins and aggregations, which can make applications and reports feel more responsive. Usually, a fast refresh takes less time than a complete refresh.A materialized views log is located in the master database in the same schema as the master table. While querying Materialized View, it gives data directly from Materialized View and not from table. A materialized view in Oracle is a database object that contains the results of a query. In Oracle pl SQL, a Materialized view is a copy of a target master, at one point in time. A materialized view is a view where the query has been executed and the results has been stored as a physical table. and hence, they need a refresh mechanism. Purpose. A materialized view log was created for the employee table, so Oracle Database performs a fast refresh of the materialized view every 7 days, beginning 7 days after the materialized view is created. A materialized view is a database object that contains the results of a query. This means that any user or application that needs to get this data can just query the materialized view itself, as though all of the data is in the one table, rather than running the expensive query that uses joins, functions, or subqueries.
