Using field symbols and data references to print database table contents
Field symbols and references are an important combination for dynamic programming. Data references are addresses of data objects stored in reference variables. Field symbols are placeholders, or symbolic representations of these data objects.
This recipe shows how to print all the contents of a particular database table (the name of which is only known at runtime). For simplicity sake, we will only focus on the main logic pertaining to dynamic programming. In addition to data references and field symbols, we will also see some dynamic SQL statement application.
