Need help on code PLSQL bit reality

Hello

I need help of reality bit on encoding.

I want to code a procedure that looks like where is a row in a table that is older, then a day and remove this line, but before that he sent an e-mail to the e-mail address that is stored in this row of the table.

Here is the example:

Table name: une_table

Columns: Username | SOMEINFO |         CREATE_DATE | CODE_THING | EMAIL_ADDRESS

Lines: user1 user1info 4 April 15 06.15.45.00PM XY2ZH89J [email protected]

User2 user2info 4 April 15 06.15.45.00PM KJH43TZH [email protected]

util_3 user2info 7 April 15 09.10.35.00PM LQT3B8N [email protected]

My test of this code (it just an example):


DECLARE
l_emailadres varchar2(50);
BEGIN
SELECT email_address into l_emailadres
FROM some_table
WHERE  create_date < sysdate -1;

APEX_MAIL.SEND(
p_to => l_emailadres,
p_from => '[email protected]',
p_subj => 'Email Info',
p_body => ‘Your row was deleted!’);
APEX_MAIL.PUSH_QUEUE();

DELETE FROM some_table WHERE create_date < sysdate -1;
END;

The problem is that there is more than one line which is given back then it gives me an error "in l_emailadres" because there is that [email protected] and [email protected] are selected.

I need a solution on this.


I'd appreciate any help.

Of course, it would be better if someone can give me a code example.

Thank you!

Of course, it seems that apex_mail.push_queue () performs a validation. It does not work with a 'for update cursor.
Therefore, place the push_queue after the loop:

declare
cursor c_x
is
Select email_address
of une_table
where create_date< sysdate="">
update the email_address;
Start
for in c_x r_x
loop
remove from une_table location being the c_x;
apex_mail. Send
(p_to-online r_x.email_address
p_from-online "[email protected]"
p_subj-online 'E-mail Info'
, p_body => "your row has been deleted!
);
end loop;
apex_mail.push_queue ();
end;

  • need help error code c355

    I have this code in my history of update?

    Hello

    1. for the update that you get this error code?
    2 did you recent hardware or software changes to your computer before this problem?

    Step 1: Install the first update manually in the clean boot state.

    Put your boot system helps determine if third-party applications or startup items are causing the problem. If so, you need to maybe contact the manufacturer of the program for updates or uninstall and reinstall the program.

    See the following article in the Microsoft KB for more information on how to solve a problem by performing a clean boot in Windows Vista or Windows 7:

    http://support.Microsoft.com/kb/929135

    Note: After troubleshooting, be sure to set the computer to start as usual as mentioned in step 7 in the above article.

    Step 2: I also suggest you to run the system analysis tool and look for problems with Windows Update.

    Step 3: You can try to download the update from the Microsoft Download Center and install it.

  • Need help with code signing.

    Hello

    I did an application that requires a code signature because I use the function 'Automatic Execution at startup' (this is what I was told).  I use not all restricted classes.

    So, I asked for a key to the RIM and received.

    I have received only a single file named "customer-CPR-# .csi" (the e-mail talked about three files however: RBB, CPR, RRT).  Nevertheless, I followed the instructions and managed to install this .csi without error (I received a confirmation e-mail).

    Now, I want to sign my code...

    I tried using "build - request Signatures ' in my Blackberry JDE and this displayed:

    javaw.exe - jar "C:\Program research in Motion\BlackBerry JDE 4.2.1\bin\SignatureTool.jar" f d "C:\Documents and Settings\johndoe\Local Settings\Temp\RIMSigTool65120.tmp"

    However, nothing happens (this jar file is there though).

    I looked beyond and found a 'Signature tool' under "Component of the Blackberry JDE 4.2.1 Package" in the "Programs" menu

    When I run this, I get invited to one. COD file.  I select my and then I see a window that shows six times my. File of COD that says that my COD file does not require a signature.

    Also, looking around this forum, I have seen some people saying a. CSL file is necessary... but I do not have this file in my project directory.

    So to make a long story short, I'm a bit confused on what do I do next for my application run at startup on the Blackberry.  How should I sign it?

    Thanks for your help!

    Please ensure that you have a current project, when you select apply Signatures from the Build menu.  The only assets of signs SignatureTool projects, so if no project is active, nothing will happen.

  • Need help with forms, plsql

    Hi, am new to oracle and do a project on the same

    Hello

    By declaring the global variable, you can pass values between Forms.

    For example

    -to declare a global variable in the triggering of the preform

    : global .wid: = null;

    or

    default_value (null, 'global.wid');

    -then on your trigger when--button of the " connection " button

    SELECT W_ID IN: GLOBAL. WID OF VOTERS WHERE V_ID =: V_ID;

    -to destroy a global variable and free its memory, use the built-in procedure clear ;

    Erase ('global.wid');

    I think that the following discussion is useful to you:

  • Need help with a 32-bit Thinapp had app to interact with Outlook 2010 x 64.

    It is a specific example, but this isn't the only application that I have a problem with any ideas are welcome.

    Here's the current scenario that drives me bananas.

    The Thinapp - Visio 2010 (32-bit, of course), packed under XP SP3 with Office 2003 is installed locally.

    Target OS - Win 7 x 64 with Office 2010 x 64 installed locally.

    Visio 2010 is running, you can virtually all do it... except, save and send-> Send as an attachment (or take the steps to e-mail).

    Basically, I tried it is difficult to explain the specific error, because they vary from "There is no default mail client installed" as many variations of "Reinstall outlook" absolutely nothing happening.

    The common theme is that the windows installer starts a repair for msmapi32.dll.  Insulation on the folder that contains msmapi32.dll (C:\Program Files\Common Files\System\MSMAPI\1033) is set to writecopy.  I even tried including msmapi32.dll inside the thinapp Visio, but I don't seem to be getting anywhere.

    Send as attachments work fine on XP SP3/Office 2003.  So I was wondering if anyone had some advice to get 32-bit apps to play nicely with x 64 apps.

    I tried to turn on/off WOWon64 in package.ini, I've got the following in my buildoptions

    ChildProcessEnvironmentDefault = virtual

    ChildProcessEnvironmentExceptions = Outlook.exe

    and VirtualiseOutofProcessCOM = 0

    All tips/tricks beyond the ordinary, much appreciated. For now, it's time for me to go home and have a beer.

    Cannot conclude something concrete now.

    It may be a good idea to install 32-bit office natively, and to observe the behavior. This way atleast we can reduce. Take your old installation that has worked for you in the other OS. Deploy it on 64 bit OS and see if it works.

    If there is a communication problem with the 64-bit native applications. We need to varify if that actually works of native office visio and 64-bit native 32-bit.

    I try to install Theme Hospital, but it says it cannot start or run due to incompatibility with 64-bit windows versions... y at - there a way around this? I REALLY want to play.

    Hello

    always check the compatibility of vista programs on the link below

    and compare it to the 64-bit tab compatibility, not only the 32-bit standard

    http://www.Microsoft.com/Windows/compatibility/Windows-Vista/default.aspx

    If a program is compatible with vista you can try right click on the setup.exe, and then selecting run as administrator

    It is not compatible with vista, you can try running it in a previous operating system mode

    This does not work for all programs

  • Need help with rewrite PLSQL function EVALUATE

    Hi all

    I'm trying to convert some PLSQL (from Discoverer) in a column of answers and I can't seem to get the correct formula.

    The original formula:
    MIN (Processed_Date) MORE (SCORE OF Business_Area, product, Serial_No)

    I guess that this must be done in an evaluation function, but I can't work on the correct syntax.

    This formula:
    Evaluate ('MIN (%1) OVER (PARTITION OF 2%, 3%, 4%)) ", Business_Area, Processed_Date, Serial_No, product)
    Has generated this error:
    [nQSError: 10058] A general error occurred. [nQSError: 22027] Union of incompatible types. (HY000)

    I do not know what causes the error, and tried casting explicitly throughout the column, but still getting errors.


    I am open to any suggestion.

    Thank you.

    Jasonr,

    highlighted in bold is the change
    Try this EVALUATE ('MIN (%1) OVER (PARTITION OF 2%, 3%, 4%)) AS the DATE, Processed_Date, Business_Area, product, Serial_No)
    update if it solved your problem.
