How do TVPs inherit schema?
TVPs reference their types from the user-defined table so they inherit the schema of the table. In this way, we can obtain a parameter that can transfer the multiple columns and rows into the stored procedure as input. In this manner, the multiple parameter values can pass as an input to the stored and then they can be handled by the stored procedure.
Why do we use the read only keyword in the definition of the parameter?
Tip: The TVPs must be declared read-only therefore we have used the READONLY keyword in the definition of the parameter. The reason for this usage method is that we cannot make any manipulation (INSERT, UPDATE, DELETE) on the TVP in the routine body.
