Games in ApEx

Hi,
Has anyone created any games in Apex?
I have some plsql code for solving sudoku that I would like to implement in ApEx (when I can work out an interface).
I would think that any of the game book ideas (if you choose to go right go to section 142, otherwise go to 122) would easily convert to the apex page format.
Regards
Michael

Thanks Doug,
I'll probably write my own interface (based loosely on yours).
Has anyone tried cards?
I wondered about cards....
If I could create a central table that people/robots could log into and record who is playing and who's turn it is.
Then I could trial one procedure against another to see which performs best.
I could even log into one of the slots myself to see if I can beat the computer!
Regards
Michael

In remembrance of last year let me share my collected (funny) quotes from this forum:
| 2010 PL/SQL Forum |
Aketi> This thread is to discussion what is difference between wmsys.wm_concat and ListAgg.
michaels2> You might then also introduce a comparison with 11g's similar (undocumented) stragg function:
BluShadow>Have they been letting Tom at the source code again!
Slow_Moe>There is most certainly a difference here. I use Toad 10.5.1.3 in both cases, just pressing the button.
We do have some issues with the database, performance wise, though. I'm starting to think it is
not completely sane (upgraded from 9i, not installed from scratch).
BluShadow>That could be an issue in Toad.
We've just installed Toad 10.5.1.3 and they certainly have seemed to manage to introduce a multitude of bugs in it.
Op presenting some large select> This was actually a query that someone else put together and asked me to fix - so I'm not actually sure what their requirements are.
Tubby> I think you should stop immediately what you are doing, i mean this seriously.
If you don't understand the requirement there's very little chance you'll have any measurable success tuning this. The bulk of tuning (in my experience anyways) comes from understanding the data, their distributions and the exact requirement needed by the query in question. Sure you can throw in the odd bit of technical magic to save the day, but i would say this is the exception and not the norm.
It's entirely possible you could transform this query into an elegant 20 line query that executes in a fraction of the time, however, that's never going to happen without understanding the question you are trying to answer.
oP> Thanks for Information.I will do in the below method.Confirm me it is OK or not
amarkiewicz >I'm not exactly a machine and can't parse it as well as the db can. It looks like a good start. Try it out and see what happens.
sybrand_b>BTW will anything bad happen if you post a question consisting of more than 1 line. Salary substracted? Fingers chopped off by your boss?
John Spencer (about naming conventions in Sql Server Db)>
Given that an unqualified name is usually resolved (only?) in the current database, and doing master.dbo.sp_help table_name gets tedious after a while, they chose to use the sp_ convention to "force" initial resolution to the master database.
Billy> So it was introduced just because they were lazy to type a fully qualified name and rather hacked the object resolution scope and introduce exceptions to what should be sacred grounds - consistent behaviour in scope resolution....
Makes sense... if you happen to be a Ferengi and dislike everything Vulcan...
OP>I am finding out that explain plan and running the optimzer tools in SQL Navigator is much to read than in sql plus.
SomeoneElse>I shall alert the media.
OP>My database session has been locked. Please suggest something.
Karthick_Arp> Kill the session.
Saubhik>Find the lock and kill....
sree>pls try alter system kill session 'SID,SERIAL#
Ulfet>Firstly investigate why session was locked. If necessary kill session.
Sven>All of you are session terrorists! All you want to do is kill...kill...kill! ;)
William>The killing is regrettable but necessary to liberate the session ;)
Billy>With most the advice offered here, you just as well can get some PE4/C4 (plastic explosives) and blow up the server. That will not only kill the "locked" session, but also kill any other potential and imagined problem arising from that server.
As William said - a session is never locked. There is no such concept at session level in Oracle. A session can be blocked - something very different from being locked.
A session can also become unresponsive for a number of other reasons. Stuck in an infinite loop courtesy of buggy code. Doing tons of I/O courtesy of bad SQL design that results in a cartesian join. Or slow because of just plain shoddy PL/SQL code. Etc.
Killing that session will not tell you anything about what happened, what went wrong, and how to prevent that from happening again.
The very first step when dealing with any IT problem is to identify the problem. Once you know WHAT the problem is, you will know HOW to address it. Killing the problem.. that only works as a solution in the military. Not in software engineering.
Toon Koppelaars>Don't believe everything you read on the internet (even not this...)
OP> what is the view?
JS1>It's what you see when you look out your window.
Someoneelse>http://theview.abc.go.com/
OP> the application generates dynamically the condition in the form :
where <condition_string> in ( 'red','blue')
Billy> You need to consider what that means in actual terms.. in terms of the data model, in terms of dealing with end user requirements, and it terms of database performance.
In most cases. this approach is fatally flawed. Is due to a poor data model and not correctly dealing with end user requirements in a performant and scalable fashion. Never mind trashing fundamental database concepts dealing with performance and sharable SQL.
OP>of course, thats what I know. I looked for a quick workaround.
Billy> So instead of running into a brick wall at a 90 degree angle, you want to see if it hurts less using a 60 degree angle?
I would have thought that not running into the brick wall at all was the aim...

Changing Column Value Style using SQL Query

Hi,
I'm trying to build a fantasy basketball game with APEX. I have a table that has a list of games. I need to change the color of the column value i.e. the name of the team that wins according to a SQL query Here's an example:
TABLE NAME: LATESTGAMES
Home Away Homepoints Awaypoints
Boston Cleveland 105 101
Toronto Washington 122 83
What I want to do is display the winning team i.e. Boston and Toronto in Green since that's the team that won.
The SQL query is:
SELECT HOME,
AWAY,
HOMEPOINTS,
AWAYPOINTS
from LATESTGAMES;
What do I need to do in order to display the Winning Team as Green on every column? Please Help

Hello Devilfish,
I did something like that in my DG Tournament application (http://www.dgtournament.com)
Your SQL query can look like this:
SELECT CASE
          WHEN (homepoints > awaypoints)
             THEN '<span style="color:green;">' || home || '</span>'
          ELSE home
       END AS home,
SELECT CASE
          WHEN (awaypoints > homepoints)
             THEN '<span style="color:green;">' || away|| '</span>'
          ELSE away
       END AS away,
HOMEPOINTS,
AWAYPOINTS
from LATESTGAMES;Hope that gives you an idea,
Dimitri

Apex 3.2 Tabular form - dynamic selection based on prev selection

Hi guys,
I am using apex 3.2. I am having difficulty in setting up a tabular form which provides an option to record information in other columns based on a value selected in the drop down.Here is an example
I have a table product. All the products are added using a tabular form by selecting type from a drop down list.
This allows the user to add multiple products without having to press save each time.
e.g.
product | type
monopoly | game
vase | home
coffee | food
cards | game
Depending on the product type, I want the user to be able to multi-select other options using checkboxes based on the option selected.
So for example if they add a product of type food, it should give additional options like beverage, cereal etc. If they select game, then they should get other options like for age_groups 10-12; 12-16; 18 and over;
Is it posisble to do this on a tabular form in apex 3.2?
If yes, please can someone help.
Thanks
Sam

"floating" table header is really amazing...is that possible to create in ApEx?
THX!

Hello Damir,
This floating table header has nothing to do with APEX. It is all HTML, JS and CSS games. You can see the principle demonstrated in the following Vikas's example - http://htmldb.oracle.com/pls/otn/f?p=24317:156 . With the same technique, you can float the report's header.
BTW, if you are looking for a table fix header functionality, already adapted to APEX, you should look into the following - Re: How to implement fixed column headers

b The nicest APEX app / feature /b

Hello,
At ODTUG I'm doing the APEX vs ADF Shoot-out, together with Lucas Jellema.
The last presentation Lucas and I did last year in the Netherlands. We decided to change some things in the presentation. One of them is to include "the nicest app or features in both environments".
So, I thought to ask the community what they think I should show.
Currently the list I thought to chose of:
* Out of the box in APEX: from raw Data to Application and Interactive Reports
* "Web 2.0" extensions in APEX: for ex. ExtJS and Dhtmlx
* Integration with Webservices, Fusion and SOA
* Extending E-business suite with APEX
(although I don't have the Oracle Applications Suite running on my laptop, so it will be hard to show)
* Integration with SQL Developer
I've about 15 mins to show the coolest, nicest features or application around, build in APEX. So it's not necessary to show things in dept or explain how to do them.
What features do YOU think make APEX incredible? Feel free to send me some screenshots or even nicer real demo sites or an application export I can show.
I know a lot of the applications we build are "internal" only, but if you could make a subset of it to just show the cool feature, that's already fine. If you just want to share what you think would be cool to show, just add a comment ... there might be a chance I already did some testing with it.
See also: http://dgielis.blogspot.com/2008/06/nicest-apex-appfeatures.html
Let's show the ADF guys something ;-)

Hi Peter,
I have a very nice anecdote about 1. APEX for Dummies!
In DG Tournament there was a problem, people couldn't login... but I didn't have an internet connection at that time and as people had to bet on the games it had to be fixed asap.
So I called my brother (as he was one of the only persons I could reach) and asked him to follow my instructions. In 5 minutes it was fixed! He's a teacher in sports, so NOT technical at all. He could do everything with his browser, no need to redeploy or have tools on his pc. I should blog about it, but then I'm not sure if the ADF guys read it, they will shoot at that ;-)
I don't want to stress 1 too much, as APEX is/was seen like that before and the marketing is also done like that by certain people, but as you also say in 2. APEX is very powerful. I see it as a fit for a lot of people; from business people who have not many technical skills to the guru developers.

Dimitri

Implementing Google Search into Apex Application

Hello everyone
I've recently been moved to handling Apex at work so I've been creating applications in my free time. At the moment, I'm working on a game wishlist application, where users can add games to a wishlist, get email updates upon release, etc.
I had the idea that a user can click on a game's title and be brought to a overview of that games details, including a news section where you could see recent news around the title. What I'd like is to integrate Google News into my application and have the search term dynamically change depending on which game the user is viewing.
Would this be possible and what would be the best way of doing it?

Not something I've ever done, but perhaps create a URL based region and define the source as the relevant google URL with your search field substituted in
ie, taking the URL example from 4.1
http://quote.yahoo.com/q?d=b&s=ORCLAnd try changing it to
http://quote.yahoo.com/q?d=b&s=&P1_SEARCH.

[b]Adding IM (XMPP/Jabber) messaging to APEX[/b]

For anyone interested on adding IM notifications to an APEX application, I have blogged about it at http://apextoday.blogspot.com . This has been a great hit with my deployed applications. In some cases sending e-mail notifications with apex_mail.send might be overkill, but some users don't seem to mind getting an IM with some useful data.

h2. Interact with Openfire
h3. How to use Oracle XMPP and Openfire
The purpose of plugging Oracle XMPP is to integrate Instant messaging in a secure way in already existing production environments, as it seems like more and more people do use XMPP for different reasons. As a DBA, will appreciate to get Alert Messages from my instances without having to open ports to the world wide web as network people do dot really appreciate to open ports to the outside. So, here we are, i'll provide you a very simple tutorial on how to interact with Openfire from Oracle XMPP.
h3. Requirements
In this howto, i'll assume that you will use Openfire and Spark default settings, so if you perform a Next/Next install, things will be straight for you.
In this very short tutorial, be sure to follow some very basic conditions.
Be sure that the Oracle-XMPP account and target user do accept messages the one from the other. In my case (surprise !!!), the XMMP used to send messsages from Oracle is the openfire configured scott/tiger user, and i'll send messages to prslump. In my case, everything runs locally on my laptop and my hostname is l20323.
In my configuration, i connect my self to the Openfire with the Spark client as prslump. That's all, we are ready to start make interact Oracle with Openfire/Spark.
h3. Test connection
Log on with your prslump/target IM account (the one that will receive incoming messages) with Spark (or any other XMPP client of your choice, like Pidgin) to your running Openfire server
Notice that everything is here running locally, so for a more realistic example, replace localhost with the server name that hosts Openfire.
Next, run from your Oracle session :
{noformat}select dbms_xmpp.test_connection('localhost',
     5222,
     'spark',
     'scott',
     'tiger') xmpp_return_code from dual;
{noformat}And you should get the following output : {noformat}XMPP_RETURN_CODE
0
{noformat}this is it. We are ready to go further.
h3. Send a Messge
In this section, scott/tiger will send a message to prslump, and it will be a bit fun. Before to run the script, be sure to always have your Spark client, logged as prslump, and at a give instant, you will see scott online, then you get the message, then back offline.... hmmm looks like dba have funny games ;-)
Therefore, just run :
{noformat}select dbms_xmpp.send_plain_text_message('localhost',
     5222,
     'spark',
     'scott',
     'tiger',
     'prslump@l20323',
     'Dummy subject',
     'Hi, this is scott talking ! Can you run stats on my schema please ?') xmpp_return_code
from dual;
{noformat}And you should get the following output (and of course your message in your IM client) : {noformat}XMPP_RETURN_CODE
0
{noformat}
h3. Get Rosters
Finally, discover scott's contacts. Hence we should (at least) discover prslump, therefore, just run :
{noformat}- get XMPP rosters
col ID for 99
col ROSTER_NAME for a30
col ROSTER_USER for a30
col ROSTER_TYPE for a5
col ROSTER_STATUS for a30
set linesize 135
select ID as "Id",
     ROSTER_NAME as "Name",
     ROSTER_USER as "User",
     ROSTER_TYPE as "Type",
     ROSTER_STATUS as "Status"
from table(dbms_xmpp.rosters_table('localhost',
     5222,
     'spark',
     'scott',
     'tiger'));
{noformat}Then we get something like that : {noformat}Id Name User Type Status
1 prslump prslump@l20323 both ITEM_STATUS_NULL
{noformat}That's all.
h3. Conclusion
As you can see, there's nothing more to configure to interact with Openfire and Spark from Oracle-XMPP. Initially, i wanted to interact with Openfire for two main reasons :
# Be able to use Oracle-XMPP in secured and closed environments
# Be able to work and develop locally while not connected to internet
I think that both goals have been achieved and hope that it could be helpfull to some of you. As always, your feedback is of course welcome.

Resources on building multi-resolution desktop games?

Hi, I'm currently working on a game and was wondering if it was at all possible to build an Adobe AIR desktop game that has multi resolution handling.
For instance, when you boot up Binding of Issac, or any other desktop game, in the settings page you can change the resolution from2560 x 1440, to 1920x1080, and so on so forth to accomadate the game to your monitors screen / fullscreen, windowed, etc.
Is this possible to do?
I've looked on the web for and I've come across is iOS resolution development. Are there any resources available for desktop games? So that hypothetically in the future, if I use Adobe Air to package up my game I could submit it to steam, and not neglect users who have monitors bigger than 1920x1080 6:9?

O.K.
This is my opinion:
If you want to create high quality applications using Apex you will need the following
(the percentages in the brackets are supposed to show the importancy in the total of 100%):
1. Good knowledge of PL/SQL and SQL (70%)
2. Good knowledge of javascript (10%)
3. Good knowledge of HTML and DOM (10%)
4. Good knowledge of CSS (5%)
5. Other programming skills (5%)
How can you get (improve) that knowledge?
1. getting a training (5%)
2. reading documentation (15%)

Can I play Game Center Games with other family members sharing one Apple ID

I have several IOS devices sharing the same Apple ID that my sons and wife use. I have set up a game center account using that ID and can find no way that we can play head to head games on those multiple devices against each other using that one Apple ID login, even if I create multiple Nicknames. Am I missing something?

An Apple ID is just an account that uses an email address and password. It does not have to be tied to iTunes. You can create one here. Create one each for your sons and wife.

Apex application registered with sso as partner application

We have 1 apex app registered with sso and working properly.
I just registered a new apex application with sso. when i authenticate through sso, it directs me to the originally registered application.
I went in through the portal administrator app and verified my settings all pointed to the new application. I verified that my dad is set up correctly.
Any ideas?
APEX 2.0

i did register and obtain the keys through portal admin.
to ensure i used the proper keys (i guess there is a possibility i used the keys from db1 registration) i re-ran regapp with the right keys but recieved the following output:

The first class defines a BALL as a THREAD
If anyone knows how to correct the code please to write....
