Query multiple keywords from one string
Hi,
I'm trying to build a search page that will give users a keyword search field and search my oracle database for all keywords entered.
I guess I need to look for spaces in the string and seperate out into an array, then build the sql dynamically from each item in the array using a loop.
Can anyone point me to any examples? Most I can find are mysql based so use functions not available in Oracle.
Many thanks.

Moving multiple queries from one category to another in QM
Hi All,
Is there is any way of moving multiple queries from one category to another in the query manager?
Or is the only way of doing it by saving each one individually into a different category.
Any ideas ?
Regards,
Rakesh NHi Rakesh,
The query manager has limited function compare with normal file management applications. Under current design, you have to do this one by one. You just need to make sure move the smaller amount of queries to large category. Category name can be changed easily.
Thanks,

Add to Multiple Tables from One Page
Hello,
I am building an application that handles hardware inventory (APEX 4.0). I have an input page that adds data to two or more tables all at once. The page has two forms on it that point to two separate tables. However when I try to run the page, it fails and returns an error:
ORA-06550: line 1, column 437: PL/SQL: ORA-00904: "ORH_LAST_UPDATE_DATE": invalid identifier ORA-06550: line 1, column 7: PL/SQL: SQL Statement ignored
Error Unable to process row of table IDD_ID_DATA.
So far as i can see within the App, that column is not at issue (I am not even doing anything to it and it is nullable). I have looked into the App itself as well as doing some online research but have found nothing helpful...
So my question is this: Is it possible to add to multiple tables from one page? If so how do I do it?
I am new to APEX so any help would be greatly appreciated!UPDATE:
I received an email from the APEX Support Team:
"The simple answer is that you will need to manually code the DML (and query) processes if you wish to maintain multiple tables from one page (There is a limit of one table when using the built-in processes).
In order to do this I suggest you delete the processes generated by the wizards and create PL/SQL processes with insert, update, delete statements as necessary. Such coding is not difficult but is more time consuming than when you can use built-in processes."
I have been playing around with PL/SQL code and the end result is this:
begin
INSERT INTO table1
VALUES(
:P2_Item_Field1,
:P2_Item_Field2);
INSERT INTO table2
VALUES(
:P2_Item_Field1,
:P2_Item_Field2);
end;
I used this code in a custom PL/SQL Process in the Processing>Processes section of Page Processing and it seems to work fine now. The only downside to this method is if the name of a Page Item is changed the code will also have to be changed. Other than that i have had no problems. -
How to copy iPhoto keywords from one library to another
I have over 30 iPhoto Libraries. Managing them is great using iPhoto Library, but keyword management is awful (if iPLM has a way I haven't found it). I would like to know how to copy keywords from one library to another. It's a pain to have to continually doing manual setup.
In advance, THANKS!With that many photos you might consider using one of the high end DAM (digital asset management) applications. I use Media Pro 1. It uses catalogs of thumbnails that are linked to the photos on your hard drive, CDs or wherever. A single catalog can hold 250,000 images. It uses Catalog Sets like Events in iPhoto. There are Categories which are like albums in iPhoto. Those and Catalog Sets are virtual. You can batch rename files once in the catalog either by date or text. The folders holding the photos on the hard drive can be set up auto update in the catalog so when you add a photo to the folder it will appear in the catalog. You can add keywords, hierarchical keywords, descriptions, etc. and write them back to the original file.
It has some built in editing capability and versioning capability. Clicking on a keyword will display all photos with that keyword quickly. Searches can be made across multiple catalogs and have the results displayed in a new catalog.
I use it as my primary DAM and iPhoto for special projects like books, etc. The catalogs can be viewed and keywords, descriptions added, etc. without the original files being available. You just can't do any editing, slideshows or anything that requires the full sized file.

Creating multiple links from one map image in Flash CS4
I have been tasked with creating multiple links from one map image using flash. Each link would go to the main website page with that location. I assume I could create a button for each location on the map but not having a lot of experience any help / tutorial you know of would be super helpful.. Thanks! Not looking for someone to work me thru it but a little guidance would be great!
If I was to answer the problem, I would be giving you what you asked not to be given... the solution. So I'll suggest that you start by researching the getURL() function. That is what AS2 uses for opening web pages.
As for coding a button, I'll recommend the following article for you... it will explain the proper approach to coding a button, which will give you an advantage over others who don't follow it, but instead use the way the article says not to.
http://www.adobe.com/devnet/flash/articles/as_bestpractices_04.html
Google is one of the best resources available for learning how to do things with Flash--it's the first place I go when I have a wondering. In general, if you type in the right keywords, you get fairly good search results. In your case, combinations of "AS2", "button", "getURL", "tutorial" would probably work well. -
Concatenate multiple columns into one string
Hello,
I am using Oracle 11.2, how can I concatenate the value of multiple columns into one string with one SQL:
create table testTb(classId number(5), classRoom varchar2(32));
insert into testTb value(101, 'room101');
insert into testTb value(101, 'room201');
insert into testTb value(101, 'room301');
insert into testTb value(202, 'room444');
insert into testTb value(202, 'room555');
I would like to generate the result as followings:
Class 101 is in room101, room201, room301
Class 202 is in room444, room555
Thanks,Hi,
Since you're using Oracle 11.2, you can use the aggregate LISTAGG function:
SELECT 'Class ' || classid
|| ' is in '
|| LISTAGG ( classroom
) WITHIN GROUP (ORDER BY classroom)
AS txt
FROM testtb
GROUP BY classid
;The generic name for concatenating all the strings in a group is String Aggregation . This page shows several ways to do it, suitable for different versions of Oracle. -
How do I transfer keywords from one photoshop to another
How do I transfer the keywords from one computer with photoshop cs6 to another computer with photoshop cs6.
I believe you can do it via Bridge CS or CC. From the Keywords Panel menu, choose Export, then Import on Bridge's Keyword panel in the target computer.
Back-ups Bridge CS6 - Collections, keywords etc.
Photoshop would then pick up on it. -

How to copy keywords from one image to many in Bridge CS6 (workaround)
I see a few questions about how to do this, but I didn't see this workaround (maybe it's even the workflow Adobe had in mind). Hope it helps others searching for this.
To copy keywords from one photo, and then apply the same keywords to many, in Bridge CS6:
Select one image that has the keywords you want to copy.
Right-click and choose File Info...
On the IPTC tab, scroll down to find the Keywords field. Select and copy the keywords you want (probably all).
Click Cancel to exit without making accidental changes.
Select the files you want to add the keywords to.
Right-click and choose File Info...
On the IPTC tab, scroll down to find the Keywords field.
Click in it and paste your copied keywords.
Click OK. Keywords are applied to all files. (NOTE: I think this replaces keywords, rather than adding to them).
I'm using CS6 on OS X 10.6.8.Sara,
Why wouldn't you just use a Windows .bat file with xcopy statements? You could even schedule it to run with the Windows task scheduler.

Scenario of multiple Asset from one AUC/WBS
Hello,
I am having a requirement, where I need to create multiple Asset from one WBS. I checked in the system and able to create more then 1 Asset for WBS.Also if I maintain the distrubution rules for those Asset then settle it accordingly to different Assets.
I just wanted to confirm, will it we the right way of handling this scenario? My main concern is this involves intervention of user for maintaing the settlement rule during final settlement.
Is there any other way to handle this scenario?
Thanks
SarangHello Virendra,
I am not using Investment Managemnt. What do you mean by IM profile?
I understand that I need to maintain the source of cost in Source structure. But even in that scenario the user has to go and maintain settlement rules and create multiple Asset against one WBS.
So how do I tackle it, if client requirement is such that they want to create only one AUC, but during final Asset creation they want to create multiple Assets from one AUC. They dont want to have WBS for each Asset.
Thanks

Passing Multiple rows from one external webpart list to another
Hi Folks,
I have almost spent 1 week looking into this without any success. I have an external list "List A" (in a webpart) with one of the columns as "State".
Another external list "List B" (in a webpart ) has state and user as columns. In some case I want to pass 1 state and in another I want to pass multiple state. Passing one state from List A to List B works fine. But Multiple state does
not work because the webpart list has the property "Send First row to connected web parts when page loads". If I disable this option then the web part does not pass anything. Is there a way to pass multiple rows from one Webpart
external list to other?http://www.sharepointanalysthq.com/2010/07/bcs-external-list-limitations/
No Lookups
Unfortunatly the only thing that you can do a look up on in an external list is on the ID column, anything else and you are out of luck.

Run multiple apps from one browser windows with 9ias r2
We are running 9ias r1 with forms 6i as our production server. Users are able to access one html page with multiple links to their applications. They can run one application, keep it running, navigate back to the html page and run a second application.
We are testing 9ias r2 with forms 9i, but when users try to navigate back to the html page to run the second application the first application closes.
Is there a way to have 9ias r2 work the same as r1 and allow users to run multiple application from one html page?Hi,

Lightbox -- Multiple photos from one thumbnail?
What I want to do is create a lightbox that launches a set of multiple photos from one thumbnail. Is this possible? All I have been able to do is create a lightbox that display's all of it's contents as thumbnails on my page. I am creating a portfolio page and I want each project's images to launch from one thumbnail. All of the projects would then be able to appear on one page. The work-around of course would be to make a separate page for each project, and make a lightbox within each one of these pages. Any solutions for this? Thanks!
You can achive this by combining the Composition Lightbox Widget with the Slideshow Widget.
01. Add Lightbox Display widget from the Composition section in the Widget Library
02. For each small grey box (the Trigger) add your thumbnail
03. In the larger grey box (the Target) add your Slideshow Widget (anyone you'd like from the Widget Library)
04. Replace images with the images you want for your slideshow

Creating multiple reports from one query
Hello Everyone
I are designing crystal reports where 1 query is built for 1 report / 1 sub-report. To improve overall efficiency of reports, I am trying to design multiple reports/ subreports from the same query. All the sub-reports belong to the parent report and they are very similar to each other.
For example: in Webintelligence, we can just create 1 data provider and pull multiple reports from it and display it in multiple tabs.
Can we do the same thing in Crystal reports??
Please advice.
Thanks
Edited by: Devesh Modi on Jun 9, 2010 11:19 PMHello,
If you are using WEBI then you have access to BOE. Create a Universe and publish it to the Repository and then you can use it as your data source.
But I think what you are asking is how to query the DB once? Not possible, each subreport will run the query each time it's viewed.
What you may want to do is create a Stored Procedure and get all of you info into one data collection and not use subreports, use grouping to emulate subreports. As an Example ....
You may want to create a case in Service Market Place since you have BOE and work with a Report Design Rep to help you work out the best solution for you.
Thank you

Generating multiple rows from one physical row
I was wondering if anyone has done or knows how to generate multiple rows for one physical row. In my query "SELECT Cust_No, Amount from Balances" if the amount is > 99,999.99 I want 2 rows returned, one with an amount of 90,000.00 and the other with an amount of 9,999.99. I'm thinking I need to use a view or function to return a result set but I'm not sure how.
Thanks in advance,
Allen Davis
[email protected]James,
Well your right in that you need a function, but also 3 views to accomplish that. I just wrote up the sql below and tested it. Basically you want the first view to return all records less than your cap of 99,999, thoes that exceed that will always return as 90,000 (see example on record PK 774177177). The second view returns money that remains AFTER the cap (in your case 9,999). The second view though also has to excude the ones less than the CAP.
DATA and TABLE layout
1) Table is called T1, columns are PK : primary key value, and N2 : some number column holding the MONEY amount
2) data is below fromtable called t1 (10 records) ...
select pk,n2 from t1 order by pk
PK N2
117165529 100
274000876 200000
350682010 9999
737652242 90000
774177177 99999
1369893126 1000
1663704428 100000
1720465556 8888
1793125955 0
1972069382 1000000
Now see the records with money at 99,999 (just like in your example). You want 2 records, so the VIEWS now come into play. The view itself CALLS the function, this occurs when you select from the view. The function will either return 90,000 (your defined cap) or the remained after subtracting the money from 90,000. The 3 views are defined below (the FUNCTION which is shown after will have to be compiled first) ...
--[VIEWS START]
CREATE OR REPLACE VIEW VIEW1
(PK,SHOW_MONEY)
AS SELECT PK,FN_TRIM_MONEY(N2,1) FROM T1;
CREATE OR REPLACE VIEW VIEW2
(PK,SHOW_MONEY)
AS SELECT PK,FN_TRIM_MONEY(N2,2) FROM T1 WHERE N2 >= 99999;
CREATE OR REPLACE VIEW VIEW_ALL
(PK,SHOW_MONEY)
AS
SELECT * FROM VIEW1
UNION ALL
SELECT * FROM VIEW2;
--[VIEWS END]
OK now for the actual function ...
--[FUNCTION START]
CREATE OR REPLACE FUNCTION
FN_TRIM_MONEY
PI_MONEY NUMBER,
PI_VIEW_ID NUMBER
RETURN NUMBER AS
LS_TEMP VARCHAR2(2000);
LI_TEMP NUMBER;
LD_TEMP DATE;
LI_CON_MONEY_MAX CONSTANT NUMBER := 90000;
LS_RETURN VARCHAR2(2000);
BEGIN
IF (PI_MONEY > LI_CON_MONEY_MAX) THEN
IF PI_VIEW_ID = 1 THEN
LI_TEMP := LI_CON_MONEY_MAX;
ELSIF PI_VIEW_ID = 2 THEN
LI_TEMP := (PI_MONEY - LI_CON_MONEY_MAX);
END IF;
ELSE
LI_TEMP := PI_MONEY;
END IF;
IF LI_TEMP < 0 THEN
LI_TEMP := 0;
END IF;
LS_RETURN := LI_TEMP;
RETURN LS_RETURN;
END;
SHOW ERRORS;
--[FUNCTION END]
I compiled the function and views with no errors. This is what I get when I query the 3 views ...
--[VIEW 1]
PK SHOW_MONEY
117165529 100
274000876 90000
350682010 9999
737652242 90000
774177177 90000
1369893126 1000
1663704428 90000
1720465556 8888
1793125955 0
1972069382 90000
--[VIEW 2]
PK SHOW_MONEY
274000876 110000
774177177 9999
1663704428 10000
1972069382 910000
--[VIEW ALL]
PK SHOW_MONEY
117165529 100
274000876 90000
274000876 110000
350682010 9999
737652242 90000
774177177 90000
774177177 9999
1369893126 1000
1663704428 90000
1663704428 10000
1720465556 8888
1793125955 0
1972069382 90000
1972069382 910000
So notice the PK entry 774177177 listed twice, once with 90,000 and other with 9,999. Also notice we now have 14 records from the original 10, meaning 4 records qualified for the split (all data from VIEW 2).
This is why Oracle kicks ass, views and functions are very powerful when used together and can return pretty much anything.
Thanks,
Tyler D.
