How to Create VIEW With SCHEMABINDING in SQL
In this article I am going to explain how to create VIEW With SCHEMABINDING in SQL
Introduction
View in SQL is a virtual table and this table is created on the result set of SQL statement. View is similar to a normal table and also have rows and columns. View may be combination of some rows and columns of two or more than two tables. You can use SQL function and WHERE clause with View in SQL statement.
View works on tables stored in database. If someone delete table then view doesn't work. You can restrict these tables that no one delete these table before deletion of view. For this we create view with SCHEMA BINDING in SQL. To create view we use CREATE VIEW With SCHEMABINDING statement.
