As Best Practices, John follows the belowlist of consideration while creating base views from SQL queries.I.SQL query has to use the SQL dialect of that database, not the SQL dialect of Virtual DataPort.II. Remove single line comments from the SQL query.III. If the SQL query invokes a PL/SQL function using an interpolation variable, you need to assign an alias to the return value.IV. If the SQL query is a SELECT query, after creating the view, John recommends setting to “yes” the “Delegate SQL sentence as subquery” property of the view.V. SQL query should not have interpolation variables, otherwise SQL query would fail.Mark the Correct Statements from the below list?
