Explanation

QueryStr retrieves a string that represents an existing query. This function is a compile-time function, which is a metadata assertion function. Compile-time functions take arguments that represent entities in the Application Object Tree (AOT) and vali- date these arguments at compile time. They have no effect at run time. Not D: The QueryRun class traverses tables in the database, fetches records that satisfy con- straints that are given by the user, and helps to gather such constraints from user input.
