How to assign the pl/sql variable to a variable of the page element?

I want to select count (*) in the emp table.

assign this count (*) total to a pl/sql variable.

How can I assign this varialbe pl/sql variable of page element?

: p2_test = pl_total;

Thank you.

Good afternoon

Try this:

1. create a process Page:

Declare
pl_total number;
Begin
select count(*)
into pl_total
from emp_table;
:P2_test := pl_total;
End;

Or a simpler approach:


Begin
select count(1)
into :P2_test
from emp_table;
End;

If you use count (1) rather that count (*), you do the inventory column 1 and not the entire file. Oracle then reads just column 1 instead of the whole of the record, speed up your query, if the table can have a large number of columns AND a lot of files.

Good luck
Don.

    Nope... no obvious difference.

    This is because there is none: Oracle's SELECT sequence. NEXTVAL FROM DUAL under the covers. The direct assignment is just a convenient encoding for us, but it does not change the work that accomplishes Oracle.

  • Result passage of PL/SQL code for the page element

    Hello

    I have created a process in after the header to fill data to the page of the form elements.  The pl/sql code is like bellows.  Then I got the error message:

    ORA-06502: PL/SQL: digital or value error: character number conversion

    My question is that I do not see the difference in format between the page element and block pl/sql variables (e.g. : P31_STUDY_ID vs v_P31_STUDY_ID), they are either numeric or text field (in fact I have hidden field, but don't see conversion back to the digital field solved the problem).  And don't see needs to set the format mask.  Is there another way to detect the column that causes the problem, or if there is a syntax error with my assignment (from the variable element on the page)?  Thank you very much!

    How to reorder the pages in boat launch?

    Hello Bob,

    Thank you for being part of the community of Apple!

    Looks like you want to change the order of the pages both in Launchpad.  If it is not possible to change whole pages at a time, you can click and hold on an application and drag it to where you want it to be.  If you want to move it to another page, drag the app to the edge of the screen, and the page will change which allows you to place it on another page.

    You can find more information about Launchpad here:

  • How to change the page numbers after adding & save page numbers in the pdf document - need to change the existing page printed on the upper right in the header numbers

    How to change the page numbers after you add and save the page numbers in the pdf document - need to change the existing page printed on the upper right in the header numbers.

    These page numbers were initially created using Acrobat PDF header and footer.

    I have a 750 page pdf document that I've created.

    I have to sometimes the pages up and down after that I added the page numbers in the document by using the Header_Footer tool on the right column of tools.

    But after you save the document, if I get a few pages around, I can't go back and change the page numbers.

    I thought that the page numbers, as indicated in the header and footer must have changed automatically, but I guess that once its print, that it cannot be edited - is that, as what is?

    So I guess we should always first get a copy without numbers of pages before confirming the documents and the creation of an index.

    A way to remove these page numbers already there and add new page numbers.

    Its a lot of work to align 750 court documents and then realize that you must move some and then realize the page numbers cannot be changed and thus begin to do this all over again to compile which can take about 10 hours.

    My question is quite simple, but I hope that overall, I got my point. Sorry if I made it is too complex.

    If no simple way, want to know if anyone has another different tool or a few recommendations to better highlight what I'm doing wrong.

    Thank you for your review and response.

    You should be able to update with tools - Pages - header & foot-

    Update... It not work for you?

    If this isn't the case, then try to remove from this menu and then re - adding them.

    I set the default for this item.but I can't able to find value in the session state itself?

    Please post your suggestion here!

    Hi Amelia,.

    Through application process only we can able to save the page element value in session state? is there another way?
    Since my requirement is like I need to display footer text in all the pages, I have the version number included in this text, so I created a table and my intention to create an item and passing the point value for all other pages and see that point value & P26_NO. in the text. Version number is dynamic, it will change at each deployment.
    Is another way simple, other than my approach?

    Thank you best regards &,.

    You should use point demand for it and an application process to fill
