What is the difference between view and materialised view?
Answer Posted / sindhu
View - store the SQL statement in the database and let you
use it as a table. Every time you access the view, the SQL
statement executes.
Materialized view - stores the results of the SQL in table
form in the database. SQL statement only executes once and
after that every time you run the query, the stored result
set is used. Pros include quick query results
