I didn't manage to get a direct flight from Brussels to SF, so I'll spent some minutes in Chicago ;-)
On October 20, somewhere in the evening, I'll cross the streets of SF for the first time...
Almost all hotels near the Moscone Center were fully booked, so I'm staying in the "Best Western Grosvenor Hotel SFO", 380 South Airport Boulevard, South San Francisco, CA 94080.
Somebody else staying there too?
I'm currently looking what to do in the evenings. This is what I already planned:
- Sun 22/10 at 7pm: "Welcome Reception" at Yerba Buena Gardens and Howard Street
- Mon 23/10 at 7pm: "OTN Night (or OTN Underground)" at the Marriott Hotel, Yerba Buena Level and sumptuous Westin St. Francis in Union Square
- Tue 24/10 at 7pm: "OOW2006 Blogger Meetup", organized by Mark Rittman in the "Thirsty Bear Brewing Company", just around the corner from the Moscone. Afterwards there's also the Appreciation Event with sir Elton John.
- There will also be a "Belgium evening" together with Oracle Belgium, but that's not yet planned. Update: Benelux Cocktailparty - Mon 23/10 6pm-9pm
- John Scott and I are also organizing an "OOW APEX meetup" evening! You can subscribe here. The post in the APEX forum is here, initially started by Joel Kallman.

This release fixes several issues in Application Express 2.2, you find the details below. The full installation of Application Express 2.2.1 can be downloaded from the OTN Site. The Application Express 2.2.1 patch set, to be applied to an Application Express 2.2 instance, can be downloaded from MetaLink (Patch Number 5500033) and is about 2.6MB.
To install the patch:
- sqlplus "sys/syspass as sysdba" @apxpatch.sql
- Copy the
htmldb_html_elements.jsincluded in the patch set should overwrite the existing file.
It took me less than two minutes to apply the patch and it worked great :-)

I've a table "Teams", a table "Team Groups" and a table "Team Team Groups" (which teams are in which groups - many/many relationship).
While I was inputting the Champions League teams I had to
1. input into table Teams
2. input into table Team Team Groups
To speed up the inserts in an APEX application, you wouldn't create two insert pages (one per table), but only one page which handles the inserts for you. You can for ex. write some (APEX form) processing which will insert the data into the two tables or tell all items to which table they belong and adapt the standard processing.
I didn't use any of these, I did the insert through a view... I built an APEX tabular form on top of the view and had my GUI very quick and easy!
An updateable view exists of a regular view and an "instead of" trigger...
SELECT t.team_id, t.team_name, t.image_id, t.team_comment, t.is_active, g.team_group_id
FROM tdg_team t, tdg_team_team_group g
WHERE t.team_id = g.team_id;
CREATE OR REPLACE TRIGGER tdg_vw_teams_groups_ioi_trg
INSTEAD OF INSERT ON tdg_vw_teams_groups
INSERT INTO tdg_team
(team_id, team_name, image_id, team_comment, is_active)
VALUES (:NEW.team_id, :NEW.team_name, :NEW.image_id, :NEW.team_comment, :NEW.is_active);
INSERT INTO tdg_team_team_group
VALUES (:NEW.team_id, :NEW.team_group_id);
Almost the same for Update and Delete...
To see if the view is really updateable, run this statement
SELECT column_name, updatable, insertable, deletable
WHERE table_name = 'TDG_VW_TEAMS_GROUPS';
My insert statement
INSERT INTO tdg_vw_teams_groups
(team_id, team_name, team_comment, image_id, is_active, team_group_id)
VALUES (tdg_team_seq.NEXTVAL, 'Shakhtar', NULL, NULL, 1, 1011);
I found it very useful to speed up my inserts like this and this solution also works from SQL Plus, SQL Developer, etc.

After two weeks of honeymoon in Mauritius I'm back in Belgium...
We booked the One & Only Le Touessrok hotel. We can recommended Mauritius and this hotel in particular to everyone! We had a wonderful honeymoon and were treated as royalties!
We stayed in the Junior Suite 283 on the Frangipani Island. One word: "Luxe".
I can write pages of our stay, but I suppose this isn't interesting enough for everybody ;-) You find some more information and pictures of the hotel here.
Mauritius, for me, has two faces... The local people are not that rich and they don't have so much luxury as we know in Europe. They work hard on the fields (sugar, textile) or they fish to survive. Next to that you've the tourism. They literally created a "dream world": island, white beaches, crystal blue water, very nice weather, palm tries and they treat a tourist as a royalty! (tourism is an other important why of getting an income)
So, now a question for you! Any news in the Oracle world in the past two weeks?
