When you use this statement, Amazon Redshift identifies changes that have taken place in the base table or tables, and then applies those changes to the materialized view. To update the data in a materialized view, you can use the REFRESH MATERIALIZED VIEW statement at any time. … That is, instead of having to construct a WHERE clause every time you want to filter the view, with an inline function, you just pass in parameters. Like a view, an inline function doesn’t have a body. On SQL Server, an inline table-valued function is as close as you can get to a parameterized view. What is the purpose of materialized view?.What is difference between view and table?.What are the advantages and disadvantages of view?.How do you create parameters in a view?.Can we pass parameter to view in Snowflake?.Which command is used to recompile a view?.How can we insert data into a view Mcq?.Why can’t we put order by inside the view?.How do you refresh a materialized view?.Can we have parameterized view in SQL Server?.Prerequisitesīefore you start practicing with various types of SQL examples given in this tutorial, I am assuming that you are already aware about what is a Database, especially the basics of RDBMS and associated concepts.
