View the results by unique identifier

Dear community,

I failed on something I do not know how to understand.

What I want is a page that contains a blank report and a LOV. When I choose something from the LOV (which is a primary key), the empty report should be filled with stored information / related to the selection of LOV.
As possible. because I could not find or have examples for this.



Explanation:

I have a 1 page.
I have a region 1 page.
I have a report on page 1.
I have a LOV element on page 1.

Selection of items LOV is pressed the report must be completed with tabledata lov selection-related.



Thank you!

"What I need on page 1, is I want all results by student.
I thought it could be done by having 1 LOV and a report based on a table (this report automatically shows all the data in the table, which is not a real problem).
"But when I select a student out of the LOV, the report should update only the results of the student."

Let's say your agenda of the LOV page called P1_STUDENT and your primary key on the table column is STUDENT_ID.

Your request would be

Select column1, 2, 3,....
FROM Student_Table
WHERE STUDENT_ID = :P1_STUDENT OR :P1_STUDENT IS NULL 

This is where your "select list item fits into the query's Where Clause"

So, following the previous tips to have your LOV P1_STUDENT point send the page when it is modified by the user, your report runs and data will be selected based on its new value and new details of the report will be generated.

-OR: P1_STUDENT IS NULL - allows the report to initially run and select all lines for all students ID's

    Kind regards

    You must have a database of information related to the pages.  If the pages are only jpeg images, then they will not be able to provide you with anything in the way of useful data searchable beyond possibly titles image.  So, you will need to create a database that contains all of the information in these pages that you can have your (matching chain) diagram of function search works with to find matching information.

  • View the results of a slider control

    HI, I'm suggling on this pl/sql, because I just started learning a few weeks ago. Basically what this pl/sql is check

    in my article "the time" to see if any time is not in the current time format and if it finds one it should display only and then someone can go and check.

    Firstly this my_table has 3 different columns which makes it the primary key, so I need display the columns so that the administrator can find the

    incorrect data easily in the time column.

    These 3 columns that actually the primary key are 'sid', "setid" and "sentry".

    I have created a slider and possesses the top loop to check all the my_table data but I do not know how to dmbs_output

    all results at once. In the results, I need to display all the columns in key primary and thus 3 under and this column that the data is.

    IF SQLCODE =-01858

    THEN

    Dbms_output.put_line (-);

    Can someone help me please.  Here are my codes

    DECLARE

    v_result varchar2 (4000);

    v_key1 varchar2 (10 byte);

    whole v_key2;

    whole v_key3;

    cursor c_get_times

    is

    SELECT sid, setid, Sentinel, time FROM my_table;

    c_get_times_row c_get_times % ROWTYPE;

    BEGIN

    TIMES a c_get_times LOOP

    v_key1: = times.sid;

    v_key2: = times.setid;

    v_key3: = times.sentry;

    SELECT TO_DATE (times.time, "HH24") IN v_result FROM my_table;

    END LOOP;

    OPEN c_get_times.

    LOOP

    EXTRACT the c_get_times in c_get_times_row;

    EXIT WHEN c_get_times % NOTFOUND;

    END LOOP;

    EXCEPTION

    WHILE OTHERS

    THEN

    IF SQLCODE =-01858

    THEN

    Dbms_output.put_line ();

    ELSIF SQLCODE =-01851

    THEN

    Dbms_output.put_line ('invalid value for minutes");

    ON THE OTHER

    Dbms_output.put_line (' failed with another unknown error: ' |) SQLERRM);

    END IF;

    END;

    If you can create the object in your schema, create the function below and the race below query it will give a correct result. I think that's the test objective you ask, otherwise do not use DBMS_OUTPUT. Just create the function and run the select statement.

    FUNCTION to CREATE or REPLACE date_chk (p_value VARCHAR2, VARCHAR2 p_format)

    RETURN NUMBER

    AS

    v_val1 NUMBER (10);

    T_DATE DATE;

    T_DATE: = TO_DATE (p_value, p_format);

    RETURN 1;

    EXCEPTION

    WHILE OTHERS THEN

    IF SQLCODE =-01858 THEN

    RETURN 0;

    END IF;

    END;

    SELECT the sid,

  • View the results of the second request when I hover over a field in a report

    Hello

    I have a table 'ASSETS', which, among other things, an ASSET_ID and a NAME column. It is possible that an asset will be alias so I have a second table, ALIAS, which has a FK to ASSETS. ASSET_ID and a column ALIAS.

    I have a report on the PROPERTY table that includes the NAME. I wish I could have the user to move the mouse over the name and have a popup (like the ' title' that you can set in the attributes 'link' to a column in a report) appear that contains all aliases the ALIASES for this ASSET_ID table.

    Is this possible and, if so, can you point me in the right direction?

    Thank you

    Joseph

    Hello

    OK - I think you need to do something like the following:

    1. create a function that returns a VARCHAR2 value. This must concatenate the alias into a single string (you can include a blowdry form layout if you use the SPAN method to view the data instead of the setting of the "title" attribute).

    2. on the column that you want to apply it, you must build the content of the cell by using the parameter Expression HTML - in there, you can use #COLUMNAME # no matter wherever you need

    Yes, I understand that the table showing in the window is not the best, but we develop this for the cushions and with highest 7-inch screen tablets.

    I am able to achieve by droping inside the Table list item > row > component cell Format.

    Don't you see the disadvantages of this approach?

  • Score &amp; view the results of a form submission

    To http://theforrestproject.org/petitionform.html , I created a petition that sends the form to my email account successfully. But I also said on the same shape as the total number of results by country and by State can be found on the bottom of the page.

    Anyone would please give me clues as to how this could be done?

    I was able to copy the corresponding code from anywhere?

    I use CS3 and I am an old man, so please, be gentle.

    Any advice on this subject would be sincerely appreciated.

    Thank you, Ian Malik.

    If your server is windows-based, you would normally use ASP and MS SQL server, not PHP/MySQL. But how many answers you anticipate? If it's under the 1000 or so there would be much less active match them manually and update the web page manually. Or find someone ready to configure for you who codes ASP. The script that processes your form of petition is PHP. It is certainly possible for PHP on a windows server, but not a MySQL database.

    Another thing, your site you say that encryption is provided for the processing of the forms, but it is not provided by the SSL Protocol (secure socket layer). The script gdform.php crypt the data when it is sent to you? And then your e-mail off sales client? If you are not convinced that the process of form is secure, so you should probably not say anything on this subject. If you went on the road to the database, then you WOULD secure your form of disinfection and validation of the data before it goes into the databsase (but SSL is not necessary for the data that you collect).

  • How can I run the process steps in the call has a shape in the workspace and view the result

    Hi all

    I hava a process with two steps

    1. one runs the sql query and returns 'invoices me' data, I put these data in the fields in my xfaForm variable
    2. the second is a renderFormPDF witch takes a repository xdp and xfaForm as form data.

    When I run the process in the workbench, I have the right result: the pdf has fields filled by extracting data from sql query.

    but when I call the process of work space it gives me only the model without data.

    I think the process is not yet completed.

    Sorry, you just have a step of user if you wanted to send the form to the user using the interface of the workspace.

    You can write the CLOB ("soapResponse" from Billy code) in a file using DBMS_XSLPROCESSOR.clob2file ().

    You can then open it with an XML Editor to understand its structure.

  • View chkdsk results

    If you plan it chkdsk to run at startup (chkdsk C:/F/R/X/B) tracks like should (I think) but I'm unable to see the last screen before final statistics it's erased vista starts quickly. I can't find a log file. Is there a log or a log is written to disk can I access once Vista starts to view the results of the last run of chkdsk. If this is not the case, can I write a batch file to the "pipes" of chkdsk output in a text file?

    Hello illegal in all fifty States.

    To view the log Chkdsk , follow these steps:

    Open the event log.
    Control Panel (Classic view)-> administrative tools-> event (3rd choice) Viewer

    The ChkDsk log can be found at...
    Windows connects (2nd choice left)-> Application (1st choice subsidiary)

    < note="">
    A number of newspapers appears in the center pane, many of them since the most recent Windows startup. You will notice the difference in time of 1-2 hours in events if you restarted to analyze (time passing runnign chkdsk). This should help you identify startup events after the scan...

    At halfway in the logs list, find the Wininit item in the source column. This will contain the log for the ChkDsk scan data before starting.

  • Why save jpg to TIFF changes the number of unique colors?

    I have photoshop cs2, when I save a jpg to TIFF file using default (LZW, Interleaved, with IBM PC byte order), I discovered the tif number of unique colors are distinguished by the jpg.

    You can test it with this jpg image:
    https://CDN.theatlantic.com/assets/media/IMG/Mt/2015/06/rbow-1/lead_960.jpg?1435518405

    If you check the jpg with the IrfanView image viewer, the number of unique color is 272662, while it is saved as tiff with photoshop cs2, the number of colors unique to the tiff file is 247160, then the number is increased from the original jpg. But sometimes, in the other case of file jpg, the number is increased. If you zoom in the tiff image, you can see that clearly some parts are like having shift artifact, or color. However if I save the jpg to tiff using IrfanView (using the default option), the number of colors unique remains same (272662).

    I also found the same problem when I save the file in jpg to TIFF using microsoft paint (I use windows 7), the number of unique colors result tiff = 272802.

    So my questions, represents changes in County of normal color in PS CS2?

    Or is it wrong that I should avoid recording for tiff with PS CS2?

    Can someone explain what's happened here?

    Thanks in advance.

    Colors never change when recording in TIFF format. Colors have already been changed when the JPEG format was opened. The TIFF record is irrelevant.

    Hello

    Impossible to refer to the alias at the same or another must therefore repeat the instruction BOX or wrap it in a view online and refer to the alias in that. i.e.

    SELECT
        c1,
        DECODE(C1,1,'YES','NO') as C2
    FROM
        (
            SELECT

  • Monitor the quality of my Internet service provider and document the results.

    OT: ping.

    I am trying to monitor the quality of my Internet service provider and to document the results.   I would like to create a ping file during the execution of the order would send ping results to the screen and a file.   I ran the file whenever the computer is turned on.  The batch file must run continuously until interrupted and view the results of ping on the screen without the statistics, and it looks something like:

    Reply from 173.194.115.4: bytes = 32 time = 19ms TTL = 52

    Reply from 173.194.115.4: bytes = 32 time = 17ms TTL = 52

    Reply from 173.194.115.4: bytes = 32 time = 12ms TTL = 52

    Request timed out.

    Reply from 173.194.115.4: bytes = 32 time = 25 ms TTL = 52

    Reply from 173.194.115.4: bytes = 32 time = 191ms TTL = 52

    ...

    In the file, it should write the results and look like:

    Wednesday, December 2, 2015 9:30:34.02 response from 173.194.115.4: bytes = 32 time = 19ms TTL = 52
    Wednesday, December 2, 2015 9:30:34.58 request has expired.

    ...

    The batch file should display the results of ping on the screen.

    In the file, it should write the results and look like:

    It is one or the other: write the result on the screen or write to a file.

    It seems that you forgot to ask a question. If you want to know how to do such a thing, so this batch file would do the trick. It will write the result in the desktop Ping.txt file.

    off @echo
    Set IP = 173.194.115.4
    value = Write date % echo %%d time % > ^ > '% UserProfile%\Desktop\Ping.txt '.

    : Loop

    Created a basic form it mapped to the same CDO on which I created the list of choices.

    Now I'm completely confused in further process.

    I did previously several times

    Suggest what to do next.

    Thanks in advance

    Is there a company need sequential ID in the CDO?

    by default, if you do not specify an identifier for the CDO and you leave the key field not mapped to form processing stage, you will have a system generated ID.  The ID is not extra if you have several actively put CDO update.
