    Dear Vinish,

    Oracle Apex report printing, I want to print My Name with Address,city & pin
    before header.

    at zai
    gholvad station
    pin 401 701
    emp no emp name salary
    1 mahendra 1000
    2 sam 2000

    How to do it in oracle apex in classic report / interactive report

    1. Vinish Kapoor

      For the above requirement, the better solution is to create a BI publisher report for it to preview/print report in PDF format or use any other third party reporting tool such as jasper reports, etc.

      Because by using the interactive or classic report, you will be able to generate just a tabular report, you can even create the groups but still you will not get the desired output.


    I want to update Employee salary using IMPORT CSV DATA

    My CSV file is

    7654 , 10 <—–There is no space in between comma
    7788 , 20
    8899 , 30







    2)  when I click UPLOAD button then CSV record stored in

    3)  When I click VALIDATE button that time in data stored in below column
    validate CSV DATA

      first column, second column, third column, fourth column 
      EMP NO     SALARY     ERROR_Yes_no, Error_Description
      7654      10        NO
      7788      20        No
      8899      30        Yes     EmpNo not found in table 

    4) when i click UPDATE SALARY BUTTON to update EMP table

    I can do step 1,2,4 but how to do 3rd step, 
    how to read APEX_APPLICATION_TEMP_FILE and update 3rd and 4th column

    what to do when I Click VALIDATE DATA button


    there is another step in Oracle Apex.



    1. Vinish Kapoor

      First, you need to check that why the validation is getting failed for 3rd step.

      And I would suggest these steps to perform your update after importing the CSV file.

      1. You create an import CSV option in the Oracle Apex.
      2. Now create a trigger on after insert event for the table in which you are importing the data.

      So now when the data would be successfully loaded, your trigger will fire for each row and will do the update as required.


    Hi Vinish,


    CSV file have three column (empno, ename, deptno) 

    Page Item 1) :P54_FileUpload

    when click UPLOAD button —>submit Page
    ———————————– Database Action –> SQL Insert Action

    • Processes –>Processing –> UPLOADED_DATA

      insert into EMP_TEMP (empno, ename, deptno) 
      (select p.col001 ,
          p.col002 ,
       from apex_application_temp_files f,
            p_content  => f.blob_content,
            p_skip_rows => 1,
            p_file_type => apex_data_parser.c_file_type_csv ) p
       where f.name = :P54_FILEUPLOAD
     apex_util.set_session_state(‘P54_DATA_UPLOAD_VALIDATE_IMPORT’,’U’) ;
    END IF;


    3)  cursor valid_data is select empno, valid_data_yn, error_desc from emp_temp
      for update of valid_data_yn, error_desc;


    No record in EMP_TEMP table

    :P54_DATA_UPLOAD_VALIDATE_IMPORT, this value is getting change on different
    different Button selection why ?



    1. Vinish Kapoor

      Hi Mahendra,

      First of all, I will suggest you to ask the detailed questions on the orclqa.com.

      In comments, you can discuss on the small issues.

      For the above issue, you mean to say, that data is accessible till the point 3) there you are able to validate the data, but not able to access after the validate data so that you can insert into the emp table.

      I think you should update the field to V so that you can access it after validation. For example:

      apex_util.set_session_state(‘P54_DATA_UPLOAD_VALIDATE_IMPORT’,’V’) ;

      And this item value is getting changed because the different tasks can be performed accordingly.

      This is the program logic written by you or maybe by somebody else, you need to handle it.
