Store procedures contain variables, loops and calls to other stored procedures. Main difference is that when you are querying a view then it's definition is pasted into your query.Procedure could also give results of query, but it is compiled and for so faster. A SQL View is a virtual table, which is based on SQL SELECT query.Also the SQL Server query optimizer will try to use an indexed view even if the view is not referenced in the from clause of a T-SQL command.These features are not available in Oracle’s Materialized Views.Oracle Instant Client 12.2 is available on many platforms.This brings the latest and greatest Oracle functionality to applications.Obviously most of the time Memory tables are faster, if you are not retrieveing alot of data. Both the INSERT and the DELETE worked in this case Obviously you can't update any fields which are aggregated or calculated but any view which is just a straight view should be updateable.You can't INSERT to this view as not all of the fields in all of the table are present and I'm assuming that PROFILE_ID is the primary key and can't be NULL. If the view contains more than one table then you can't insert or delete but if the view is a subset of one table only then you usually can.

However, using views that return very large result sets can lead to poor performance, as the result set is not indexed and the entire result must be table scanned if the view is used in a join or a subquery of a T-SQL command.View is simple showcasing data stored in the database tables whereas a stored procedure is a group of statements that can be executed.A view is faster as it displays data from the tables referenced whereas a store procedure executes sql statements. Exactly what you are looking for @Patrick is correct with what he said, but to answer your other questions a View will create itself in Memory, and depending on the type of Joins, Data and if there is any aggregation done, it could be a quite memory hungry View.Please consult the license agreement and your legal department for clarification, if necessary.

With SQL Server 2000 (Enterprise Edition), Microsoft has introduced the concept of Indexed Views, which can make your applications and queries run faster in the right circumstances.The data accessed through a view is actually constructed using standard T-SQL select command and can come from one to many different base tables or even other views.
