#Basics of Views-Sql Server

Views : They are virtual table and are generally combination of 2 or 3 tables.Being said Virtual they do not occupy space like a normal table.

Indexes on View :

Views are virtual table by default,to use index it’s mandatory to have a physical column.To enable indexes its mandatory to use SCHEMABINDING with views.

with schemabinding 


select  v1.column1 ,v1.column2 from v1 

Refreshing Views:

Since views are virtual tables,there might be cases where we need to refresh a view when underlying table used in view changes.

Execute SP_RefreshView "yourviewname"

 Single select must be used in view with check option enabled.
