New ACCESSIBLE BY Clause: Oracle 12c

You might implement a database application as several PL/SQL packages—one package that provides the application programming interface (API) and helper packages to do the work. Ideally, only the API is accessible to clients.

Also, you might create a utility package to provide services to only some other PL/SQL units in the same schema. Ideally, the utility package is accessible only to the intended PL/SQL units.

Before Oracle Database 12c, PL/SQL could not prevent clients from using items exposed in helper packages. To isolate these items, you had to use relational database management system (RDBMS) security features. Some application deployment schemes made RDBMS security features hard to use.

As of Oracle Database 12c, each of these statements has an optional ACCESSIBLE BY clause that lets you specify a white list of PL/SQL units that can access the PL/SQL unit that you are creating or altering

How to use lexical parameters in Data template (XML document) R12

Lexical parameters can be added in data definition using &variable name This is flexible variable string where you can execute runtime conditions based on user-inputs Example 1. Append &gc_journal_filter at the end of sql statement 2. Define beforereport function in package signature FUNCTION beforereport RETURN BOOLEAN; 3. Define all the report parameters as a package variable in package signature including lexical parameters 4. Implement beforereport function by building your runtime conditions to be added to SQL statements  FUNCTION beforereport RETURN BOOLEAN IS  BEGIN          IF p_journal_source IS NULL THEN       gc_journal_filter := ' AND jh.je_source IN (''AutoCopy'',''Manual'')';     END IF;          IF p_journal_category IS NULL THEN       gc_journal_filter := 'AND jh.je_category IN (''Other'') ';     END IF;    RETURN TRUE;  END;
