As you can see from the preceding code example, subroutine attributes can also have an argument (make sure there s no space before the parenthesis containing the argument, or your application will not compile) The built-in subroutine attributes for Catalyst controllers are implemented in the Catalyst:: Controller module, where the parse_XXX_attr methods provide the attributes for the dispatcher You can make your own with a base controller (we ll cover this in 10) The types of actions built into Catalyst are Private, Local, Global, Path, LocalRegex, Regex, and Chained Of these the first three do not take any arguments A Private action is one that cannot be accessed by visiting a particular URL; it can be invoked only through a forward or a detach within a controller In fact, this is not quite true For backward-compatibility reasons, default : Private and index : Private are special, publicly accessible private actions.

You sometimes need this (apparently) superfluous grouping on additional columns. For example, suppose you want to see the employee number and the employee name, followed by the total number of course registrations. The query in Listing 8-32, which could be a first attempt to solve this problem, produces an Oracle error message. Listing 8-32. Error Message: Not a GROUP BY Expression e.empno, e.ename, count(*) employees e join registrations r on (e.empno = r.attendee) group by e.empno; select e.empno, e.ename, count(*) * select from

ERROR at line 1: ORA-00979: not a GROUP BY expression The pseudo-intermediate result in Listing 8-33 explains what went wrong here, and why you must also group on e.ENAME. Listing 8-33. Pseudo-Intermediate GROUP BY Result GROUP BY e.EMPNO e.EMPNO ======= 7369 7499 7521 7566 e.ENAME ========= {'SMITH'} {'ALLEN'} {'WARD' } ... e.INIT ... ====== {'N'} {'JAM'} ... GROUP BY e.EMPNO,e.ENAME e.EMPNO ======= 7369 7499 7521 ... e.ENAME ======== 'SMITH' 'ALLEN' ... e.INIT ... ====== {'N'} {'JAM'} ...

Prompt for color of redlines: If this check box is enabled, Opticon will prompt the user to define the color of each new redline as it is created, using the Color dialog (see Figure 12-15). When enabled, the Color dialog will open immediately after a redline is created. You should select this option if you intend to create a series of redlines, each with its own custom color.

We don t use these any more instead of sub default : Private, we use something like sub default : Path, and instead of sub index : Private, we use sub index : Path Args(0) However, these can have any name you like, for example, sub do_404 : Path and sub homepage : Path Args(0) Using the Path attribute for the index and default actions, compared to the old method of special private actions, creates consistency across all of our controller actions For example, if we had the following subroutine definition in our application s Controller::Root, it would run if we requested /something or something_else, so long as we didn t actually have any definition that explicitly caught these arguments: sub level1_catchall : Path : Args(1) { .. We can also provide an argument to the Path attribute as follows: sub doit :Path('dog') :Args(1) { ...

The two results look similar; however, there is an important difference between sets consisting of a single element, such as {'SMITH'}, and a literal value, such as 'SMITH'. In mathematics, sets with a single element are commonly referred to as singleton sets, or just singletons. Listing 8-34 shows another instructive mistake. Listing 8-34. Error Message: Not a Single-Group Group Function select deptno , sum(msal) from employees; select deptno * ERROR at line 1: ORA-00937: not a single-group group function In the absence of a GROUP BY clause, the SUM function would return a single row, while DEPTNO would produce 14 department numbers. Two columns with different row counts cannot be presented side-byside in a single result. After the correction in Listing 8-35, the error message disappears, and you get the desired results. Listing 8-35. Correction of the Error Message in Listing 8-34 select , from group by deptno sum(msal) employees deptno;

Figure 12-15. The Color dialog. You can select a predefined color from the Basic colors palette, or define a new color using the Define Custom Colors button.

DEPTNO SUM(MSAL) -------- ------------10 8750 20 10875 30 9250
