oracle - PL/SQL private object method -

-

Oracle's PL / SQL (using 10G) I'm a little new, I was wondering if there is a way to do this in a personal type of object type, as often as other languages ​​(Java, C ++, C # Etc etc.) are used for personal accessory methods. It is possible to do personalized methods in the address package, but I can not find a way to do this for object types. I am telling compiler errors: 

 Error: PLS-00539: Subprogramme 'FOO' is declared in object type body and defined in object type specificity.

OK, here's a possible solution that I have tested very briefly, and it's still Works:

The parent object type that will be marked as not final and undesirable and then put all the private code there. Private methods will not really be private, but putting them in such a way that is not the last and prevents them from calling them instantly. In the immediate subtype, refer to "private" methods in SuperTem via SELF. Example: 

  Type the privatefu (member process setUpCommonFoo) under Superfu, not INSTANTIABLE; Creating or changing a private body type - Member procedures and methodology set up the member process setCommunfu starts SELF.SomeAttrib: '' Some Common Default Values'; End; End; Type or fuse type fu under the personal foo (resultant constructor function Foo return results as SELF, Constructor Function Fu Return results as SELF - Suppose that FQ is defined in Superfu, and Fuchi type somewhere Is defined;) The body is for the establishment of Fu - No-erg Constructor Basic Fu. The controller working party converter itself as the result of itself. SetupMeeting FU; Return; End; Free Manufacturer for Other Positions ... Constructor Function Party Convertor (FKI) returns as SELF returns such as the self Staff up Commonfu; SELF.RrelyUsedAttrib: '' Special Price! '; - Suppose something is attached and rarely used. Atreb is actually present;) self.fkey: = fkey; Return; End; - Other members go here ... end;

Now I have to accept, I really do not like this pattern. It sounds weird and weird, I'm probably going to avoid the object type as much as I can stick with the package (or very similar object type). A package-of-phariari helps to resolve the private common code problem only for consultants, not for other types of normal code refactoring.

... As long as there is no better way to work with the object type .... Anyone? anyone?

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
