      Description

      Unable to use user-defined function within view.

      Steps to reproduce:
      Create a new schema with User Defined Function and View.
      Use the new user defined function in the View SQL
      Execute query with UDF
      => Success // UDF is registered successfully
      Execute query on VIEW
      => Error : No match found for function signature MY_INCREMENT(<NUMERIC>, <NUMERIC>
