What is the result of with Schemabinding in a view?
In SQL Server, when we use the “WITH SCHEMABINDING” clause in the definition of an object (view or function), we bind the object to the schema of all the underlying tables and views. It also means that the underlying objects cannot be dropped.

What does the keyword with Schemabinding mean and why would you use it are there any prerequisites to using it?
Answer: SCHEMABINDING keywords prevent tables used in the views to make any such modifications that can affect the view’s definition. When this keyword is used in the view it binds the view to the schema of the underlying tables.
What does with Schemabinding mean?
SCHEMABINDING is an option that is available for objects in T-SQL which contain user defined code. Specifies that the schema is bound to the database objects that it references. This condition will prevent changes to the schema if other schema bound objects are referencing it.

How to remove schema binding from a UDF?
You can remove schema binding from a UDF, make the changes to the base object/s, then reapply schema binding. There are two ways to remove the binding of a user-defined function to its base objects: Alter the function so that its definition no longer specifies schema binding.
Why do I need schemabinding in a user defined function?
The purpose of schema binding a user-defined function (UDF) is to ensure that the base objects referenced in the UDF cannot be modified in a way that would affect the function’s definition. This is fine, as long as you don’t need to make any changes to the underlying objects.
What to do with schemabinding in SQL Server?
Create a table. Create a SCHEMABOUND UDF. Create a COMPUTED PERSISTED column that references the UDF. Add an INDEX over said column. Try to update the UDF. Good luck with that one!
Can a schemabind view reference other schemabound views?
One downside is that if you schemabind a view, it can only reference other schemabound views. I know this because I tried to schemabind a view and was met with an error message telling me it could not be schemabound because one of the other views it references is not also schemabound.
