The limit to the number of columns to display in the report. Help!

Hi all

Maybe this is a stupid question. But why get this error with a report of the IR? and what is the solution for this. Please help me with this.

Error

The limit to the number of columns to display in the report. Please, click on select columns under Actions menu to minimize the list of columns in report view.

Oh... And I also have a blob column... If the format is not given, the table is very good... but happen to get this error only when the BLOB download format is given.

Thanks and greetings

Hello

I implemented a small suitcase of test on apex.oracle.com and I get the error even if I use the download format.

I have a table
test_blob (identification number, name varchar2 (10), blobcont blob)

If I create IR as

  select
    id,
    name,
    blobcont
  from test_blob

and then I set the download format I got the error.

If you want this to work you need to change your query to

  select
    id,
    name,
    dbms_lob.getlength(blobcont) blobcont
  from test_blob

And there still define download for blob on column blobcont format.

Kind regards

  • Max Number of columns allowed in Discoverer 9i / 10g report

    Hello

    I need to prepare a report of discoverer 9i which has 62 columns. Does anyone know how the Max number of columns is allowed in discoverer reports. I'll be able to include all of the 62 columns without any problem?

    Thanks advanced

    Lokesh.

    Hello
    Although I couldn't find any document about it, I don't think that you will have a problem with the discoverer.
    I don't know how the java it take good care.
    From the Viewer (and I hope I'm not mistaken and mislead you) in the definition of columns
    You can choose up to 999 columns to present so I guess that there will be no problem with 62.

    All documentation on its limits?

  • editing a table to add the number of columns fails with ORA-01792

    I'm editing a table to add columns, and ORA-01792 receiver: maximum number of columns in a table or view is 1000. The table of the altar will be no more than 1000 columns. The environment is RHE5 Oracle 11.2. ALTER statement adds a lot of columns in the table, but when I do a manual change to add a dummy column it works, after that, if I run the original the change works!

    What is a table compressed with unused columns?

    This may explain the error with the limit of 1000.

  • limiting number of column in the 4.1 apex data loader?

    Hi all!

    Is there a limit on the number of column in the APEX 4.1 data loading page?

    My DB object has 59 columns and they are all available in single colum drop of my load sample data table definition boxes.
    On page two of the wizard created database load pages "data/table mapping" columns only 45 is indicated. These columns are correctly inserted in my table. The last 14 columns are ignored.

    If anyone knows if there is a limitation and can it be extended?

    Thanks for any reply and cordially

    No, I don't have a solution for this.

    Split the file within columns each, with the primary key that is repeated and then sting tables up to post upload could be easier than to use other roads.

    And then there's always the good old SQL Loader and external Tables. But the integration of these into the Apex is not easy because Apex runs on the server and the file is usually the disk of HARD local to the client.

  • Impression of infinite number of columns in addition of Table to the report


    Using the VI "Append Table to declare", you cannot specify Center alignment, through if you enable the grid, it's easier to read tables.  If you generate an Excel report, you have more control and be able to specify the alignment of the cell.

    There is no way to get or to automatically print the page number in the Toolkit of report, using Standard report generation.  You can do this manually keep track of how many pages have been printed if your using the new report Page' VI.

    Using the VI script that you posted, I changed to illustrate adding selectively the columns on the report.  His practice is usually not standard for us to write code to customers, but this example seemed good for the Page example of Community (http://www.ni.com/code/) and with your permission, I would like to post here as well.

    How can I get the number of columns?

    It is a type of associative array definition. A table has no columns. It is a collection of elements (variables or values). An array location is usually called a cell.

    The standard method Count() exist in Oracle for all table types.

    As for the definition of the table, as in structures, variables make the table contain - associative array is defined in the PL/SQL code and does not exist in the layer of metadata to the database as a new user-defined type. For the definition, you must read the declaration of PL/SQL defining the table.

    Note that there is very rarely the need for associative tables in PL/SQL - 99% of the time they are used without any idea as to what as a table associative is also.

  • Query the number of columns have data in a Collection

    Hello

    Apex 4.2.

    I use the EXCEL2COLLECTIONS plugin to import csv data into a collection.

    I am now validate the collection and would like to know the number of columns in the collection were given.

    For example, if my collection has less than 10 columns with data, then I want to generate an error

    Is there a way to do it

    Concerning

    How and where is the best place to use this code.

    What type of validation

    You said:

    I am now validate the collection and would like to know the number of columns in the collection were given.

    and

    Otherwise, I should raise an error or enter an error indicator and the error message in columns 11 and 12

    So one could assume that aspect was already developed.

    The short answer is that without knowing the details of what you are trying to do, how your do it, and how you have reached: don't know.

    I expect this kind of import of data includes several pages forming a multi-step wizard, so there are a lot of possibilities. For example, use it in a cursor FOR loop to set the above error flag and message columns, then conditionally branch to a report with errors page if error indicators exist in the collection, or the next page of the wizard, if they are not.

    PDF does not contain columns, lines, formats, styles or other aspects of word processing or spreadsheet file formats.

    This is because the PDF is decidedly not a file format of word processor or a spreadsheet or something 'like' one of these.

    (see ISO 32000 for what PDF "is")

    Which allows to optimize the export of the content of a page PDF is to start with that tag well formed PDF (ISO 14289-1, PDF/UA-1).

    Without that export is what it is and we performs the cleanup of any necessary content using the native application for the export of files (MS Word or Excel).

  • How to export data to excel that has 2 tables with the same number of columns and the column names?

    Hi everyone, yet once landed upward with a problem.

    After trying many things to myself, finally decided to post here...

    I created a form in form builder 6i in which clicking on a button, the data gets exported to the excel sheet.

    It works very well with a single table. The problem now is that I cannot do the same with 2 tables.

    Because the tables have the same number of columns and the columns names.

    Here are the 2 tables with column names:

    Table-1 (MONTHLY_PART_1) Table-2 (MONTHLY_PART_2)
    SL_NOSL_NO
    MODELMODEL
    END_DATEEND_DATE
    U-1U-1
    U-2U-2
    U-4U-4
    ..................
    ..................
    U-20U-20
    U-25U-25

    Given that the tables have the same column names, I get the following error :

    402 error at line 103, column 4

    required aliases in the SELECT list of the slider to avoid duplicate column names.

    So how to export data to excel that has 2 tables with the same number of columns and the column names?

    Should I paste the code? Should I publish this query in 'SQL and PL/SQL ' Forum?

    Help me with this please.

    Thank you.

    Wait a second... is this a kind of House of partitioning? Shouldn't it is a union of two tables instead a join?

    see you soon
