A couple methods are applicable to almost all, if not all, table packages and object TYPEs. They are get_id and inactivate(). The method get_id is shown without parentheses because it takes no arguments. From my point of view, these black box methods should exist in every table package and object TYPE. Let s start with get_id.

Method get_id allocates and returns a new primary key value from an underlying Oracle sequence. FUNCTION get_id acts as an abstraction layer between the underlying Oracle sequence and PL/SQL. This abstraction layer allows you to later change the means by which you allocate a primary key value without having to recode any PL/SQL program units that call the method. The following is an example of the get_id method from code table package WORKER_TYPE_TS: FUNCTION get_id return n_worker_type_id begin select WORKER_TYPE_ID_SEQ.nextval into n_worker_type_id from SYS.DUAL; return n_worker_type_id; end get_id;

Rarely have I encountered an application where I actually delete data from a table. Instead, applications work with the idea of inactivating or invalidating an entry. Method inactivate() handles inactivation. If you have a code table, you can t delete a code value that s in use (one that has any relationships). Yet, you may want to stop users from using an outdated code value. To do so, you write your code value s SELECT statement to utilize the code s inactive date, and then you set a code s inactive date so users can no longer select it from a list of values. Along the same line of thinking, if you have a content table, and a particular entry has relationships, but you no longer want users to select the content table entry, you can set its inactive date and prevent it from appearing in the presentation layer. Just as with the code, the content entry has historical significance but is no longer to be used. With an intersection table, the concept is slightly different. With an intersection, the assignment of a relationship between two tables exists for the period of time defined from its active date through its inactive date. So when you inactivate an intersection entry, you re simply defining the end of a historical relationship. Regardless of the type of table for which an entry is inactivated, inactivate() does the same thing: it sets the inactive date. The following is an example of an inactivate() method from content table package LOGICAL_WORKPLACE_TS:

PROCEDURE inactivate( ain_logical_workplace_id in LOGICAL_WORKPLACE_T.logical_workplace_id%TYPE, aid_inactive_date in LOGICAL_WORKPLACE_T.inactive_date%TYPE) is begin update LOGICAL_WORKPLACE_T set inactive_date = aid_inactive_date where logical_workplace_id = ain_logical_worplace_id; end inactivate; That s straightforward enough. Now let s look at methods used by all packages and TYPEs.

Universal Methods
I expect some methods to exist in every package or TYPE. You ve already been introduced to methods help and test. I have one new one here named initialize. Let s start with help.
help
Method help should display help text for the package or TYPE for which it is executed. PROCEDURE help was covered extensively in 9. You should code this method to display help text in whatever manner you find suitable. What I showed you in 9 was just an example. But, whatever you do, you must be consistent; otherwise, programmers won t consider the help as reliable documentation, and then you ll have defeated the purpose of coding the method altogether. The following is an example of the method from code table package WORKER_TYPE_TS: PROCEDURE help is begin TEXT_HELP.process('WORKER_TYPE_TS'); end help; In this example, PROCEDURE process() in package TEXT_HELP will format and display the contents of the associated specification.
initialize
I know I have not talked about method initialize before, but I feel it s an important part of testing and should exist in any package that uses its initialization section. Just in case you don t know what I mean by initialization section, let me elaborate. A package body is a PL/SQL block. Because it is a PL/SQL block, it has a declaration section, which is where you code any instance variables, functions, procedures, and so on, and it has an executable section. Really, it does. If, after all the functions and procedures you coded, you add the keyword BEGIN, any code from the keyword BEGIN to keyword END at the end of the package body is executed once, and only once, any time the package is instantiated. By instantiated, I mean loaded into memory and initialized. There it is, that word: initialized.
