Multiple Rows Update / Refresh Toplink Query when database trigger involved

Hi everybody!
I have two easy troubles for you; the platform is the same as the SRDemo Toplink version.
1. Multiple Rows Update: I want to update with mergeEntity method, multiple rows for an isolated table; that method receives a parameter that I try to bind with the iterator "dataProvider" but it only merges the first row, not all, any other combination returns an error.
What I want to do is to have a form (like tabular forms in Apex) that lets me update multiple rows in a single page. ¿May anyone tell me how to do it?
2. Refresh Toplink Named Query: I have a list on a page with two columns. From another page, a button does an action that fires a database trigger that updates one of the columns on the list´s page. When I go back to the list, it is not updated; however, the CacheResults´s property is set to false on the iterator.
Thanks in advance,
Alejandro T

I didn't use it (yet), but - you might take a look. You'll find a [url http://www.oracle.com/technetwork/developer-tools/apex/application-express/apex-plug-ins-182042.html]Timer plug-in on this page. It is a dynamic action which allows you to periodically fire other dynamic actions in the browser. For example use the timer to refresh a region every five minutes. You can perform any dynamic action you want using this infrastructure.So I was thinking: you might use it to run a dynamic action which would check whether something changed in that table (I suppose you'll know the way) (for example, a database trigger might set a flag in some table, timestamp or similar), and - if you find that something really changed - refresh the page.
As I said, I never used it so that's pure theory. Someone else might know better, though.

Multiple row update; CEV business rule parameters are not refreshed

During a multiple row update, a business rule is fired for each row.
This change event business rule must update the value of another column in the same table (and same row).
Unfortunately, the parameters of the BR are keeping the values of the first row that has been checked. Since my parameter p_id always keeps the same value, I always update the same row.
Does somebody have a hint on how to solve this problem ?
I'm using Headstart R6i and Forms6i with Oracle9i DB.
Thanks in advance for your help,
Denis.

I think that's how it works. I tried that with a variable where type is Members.
It is not showing me a prompt when i select multiple rows. However works only for first row. (even if the menu is initiated from second row).
Multiple rows selected, variable type is members. works only for first row in selection. (in 11.1.2.2) You can try log an SR and see what Oracle has to say.

Multiple Rows Update

Hi,
I am creating a form which will display the multiple rows from the table. Is there any way to make multiple rows update at the same time.
If it is report generated by the query, can we do multiple rows update.
Regards,
Munish

Munish,
Sounds like what youâre looking for is a tabular form. Click on create page, then choose form, then tabular form and follow the steps of the wizard. This will create a tabular form for you that lets you update multiple rows, add new rows and delete multiple rows.

Marc

Hi,
Whenever you have a question involving an error message, post the complete error message, including line number. Don't you think that might help people solve your problem?
Whneve you have any question, post a little sample data (CREATE TABLE and INSERT statements) and the results you want from that data. (In the case of a DM<L statement, like UPDATE, the INSERT statements show the tables before the change, and the results are the contents of the changed table after it.)
Review the syntax of the UPDATE statement in the SQL Language manual:
http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_10008.htm#sthref9598
MERGE may be more efficient and easier to use than UPDATE.

Multiple Row Update in a Table

Hi,
How do I do a multiple row update in a single table in Oracle? I was thinking of something that is similar to the insert example below:
Insert into SOME_TABLE (COL1, COL2) (select COL1, COL2 from ANOTHER_TABLE);
...wherein I don't have to write multiple lines of update statement.
Thanks.

Hi Mike,
Thanks for replying. I was actually looking for a multiple row update using a single update statement. The only reason I provided an Insert statement example is to show the idea. I did some test and I was able to figure it out. I thought it was something complicated but I just had to retrieve the new values from another table and equate the primary key and foreign keys of the two tables.

Multiple SQL Update within Parent Query

I am tring to extract an image from within a MS SQL image field,
opening the image using JAI, getting the src.getWidth() & src.getHeight
() of each item within the database, and then writing the width and
height back into the database. Everything works except when I goto
write the values into the database - the page (when loading) continues
to work and work and work until I restart the tomcat service. I do not
understand why this would occur, and what is even stranger - I have
very similar code i used for resizing images in the database into a
thumbnail - display and original file sizes using a similar approach...
and that works with out a problem...
I have tried the code with out the inner update query - it works. I
tried with just the selection of a single specific item in the first
query and that works, but when I try multiple updates the second query
appears to stall.
The code is as follows.:

URGENT!!! Can't implement a Multiple Row Update Process

Hi All,
I'm a total newbie to APEX and wondered if anyone could help.
I've created an Application using the "Report and Form" template. My Table, call it tab1, has a pk called pk1 and four fields, f1, f2, f3 and f4. The Application has 3 pages, p1 is the login page, p2 is the Report and p3 the Form. The Report is fine and I've added a search on the Report based on the pk. The Below is an example of the output of a Report filtered on the value pk=3:
PK F1 F2 F3 F4
3 21 A C A
3 21 B B C
3 21 C A A
3 21 B D A
Each of the 4 rows above then links into a Form on P3 for updating, so if I clicked on the link for the first row the Form would like something like this:
PK 3
F1 21
F2 A
F3 C
F4 A
Now here's what I'm trying to achieve. I've created an "Update" button on p3 and when I press this I would simple like the below statement to be executed:
Update Tab1
set F4 = :P_4,
F3 = :P_3
where F1 = :P_F1
where :P_1, :P_3 and :P_4 are the values inserted by the user. So basically I want to do a multi-row update based on a non-primary key. In this case I would want 4 rows updated after pressing the Update button.
Any help would be most appreciated.

ADF JSF - Multiple Rows Update

Does anybody if there is a new component in ADF JSF that allows update of multiple rows? Se example...
ID     | Name | Number
1     | textbox | textbox
2     | textbox | textbox
3     | textbox | textbox
|Create- button| | Save - button|

Sure, the ADF Faces <af:table> supports updating multiple rows: just put an <af:inputText> inside one of the columns.

JDBC Receiver - Multiple rows Update

I have an interface the incoming message contain multiple columns and it has to be updated using a JDBC Receiver Adapter with its key values.
Can we send multiple rows in a single JDBC Update Statement.
Please advise.

Sebin,
No ,it's not possible to have multiple rows in single update statement. Rather you can duplicate the segment at Statement level and do the update.

You can also use correlated update. This one is from AskTom (http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1197999096334)

How to process multiple rows of data into a single string

Hello,
I am trying to process multiple rows of text from an Oracle database into one field to display on a report as continuous text. Below is sample data. The text field is 55 characters wide so anything longer is broken into multiple rows. I need to recombine it for display.
line          text
1             IN THE N.E. QUADRANT OF THE INTERSECTION OF THE FAIRFAX
2              COUNTY PARKWAY AND THE DULLES AIRPORT ACCESS AND THE T
3             OLL ROAD AND SOUTH OF SUNSET HILLS ROAD
I tried creating a formula field but it did not work, below is the code in Visual Basic syntax. I also tried using the Maximum() and UBound() functions without luck. I don't quite understand how to make the UBound() work; it threw a lot of errors.
Dim i As Number
Dim strLocDesc As String
For i = 1 To count({LDS_AR_RL_COMM.ART_LINE_NUM})
    strLocDesc = strLocDesc & {LDS_AR_RL_COMM.ART_COMM_RMK}(i)
Next i
formula = strLocDesc
Any ideas on how to solve this?

Hello Allison,
You can try this:
Create a formula called @StoreText, place it in the details and have the following code in it:
WhilePrintingRecords;
Global StringVar Text1;
Global StringVar TextRest;
if {field.line} = 1 then
Text1:= {field.text} else
if {field.line} >= 2 then
TextRest := TextRest+" "+{field.text};
In the Group Footer you can have a formula called @GetStoreText with the following code in it:
WhilePrintingRecords;
Global StringVar Text1;
Global StringVar TextRest;
Text1+varTextRest;
See how that works out for you.

Zack
