• How can I know the number of columns in a TYPE?

  Hello

  If we have a guy like below

  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.

• I need to convert PDF to Excel, however, the columns and tabs make many merged cells and the number of columns empty. In addition to not separate the columns properly, I see many not separate lines together in the same cell. I think same as Adobe Acrobat

  I need to convert PDF to Excel, however, the columns and tabs make many merged cells and the number of columns empty. In addition to not separate the columns properly, I see many not separate lines together in the same cell. I even think that Adobe Acrobat Pro DC has limits. There is no way to set what points in columns to force the column break? Or create several columns that are unnecessary? How column in Excel, size fixed when import us text and define where breaks have columns of text?

  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).

  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.

  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

• Need to limit the number of columns

  When a tab in the last cell of the row, I want the cursor to the next line down. Instead, it creates a new useless column. Can't seem to find a setting that allows me to limit the number of columns in a page - someone ' one knows how to do this?

  Thanks for your wisdom shared, Oh wise Ones.

  I'm not aware of do what you want.  You can post your comments directly to Apple using the menu item "numbers > provide Feedback numbers.

  You can still use the key combinations:

  < command > + < right arrow > to access at the end of a line

  < command > + < left arrow > to move to the beginning of a line

  < command > + < down > to pass at the end of a column

  < command > + < arrow > to move to the beginning of a column

• 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.

• DR IP customizer: error on line number '17': the number of columns specified is incorrect.

  Hello

  I work with MRS 4.1 and trying to customizations ip configuration for my virtual machines guests on the recovering site (approx. 100 guests).  I've updated the CSV (generated from the order of Dr. - ip - customizer.exe) with all the necessary network information.  But when I try and upload it to my site SRM recovery server, I get the following error:

  Error on line number '17': the number of columns specified is incorrect.

  Is the command I use to download: Dr. - ip - customizer.exe - cfg... create csv - c:\srmip.csv - cmd \config\vmware-Dr.xml

  I found that if I change the csv file so that it contains 16 lines or less it downloads very well.  I have not read on any limitation of the number of rows in the csv file might contain so I think that there is a configuration that causes this behavior, but I can't figure out what that/where it is.  Any help would be greatly appreciated.

  Thank you.

  Hello

  something is wrong with your file formatting. A look at the image as an attachment. From the server6 (line 17) do not have the lines "," (comma) at the end of the line (and so less columns):

  

  If I take your file and then open in Excel and save it without changing anything, all lines have ',' (comma).

  Probably something wrong with the way in which you save the files (Excel throws several warnings when you try to save the file in the csv format, you have to press 'Yes').

• Display the icon change the number of columns

  I'm sure it must be a way to change the number of columns in the display icon, not the space between columns, not the size of the icons, but the number of columns, for example, that dumpster has 4 columns and I want to see those hidden on the right I have to use the scroll bar, I want to do I want to see ONLY for columns of the filling finder window?

  Thank you very much

  Nobody wants you to post 1 million rows. 10 lines can be many. Just examples of data make sure that validation really produces the results you post.

  I copied data from 16 Jan just differentiate different dates.

  I also tried trunc, but who has still not the sum of each divisions.

  Highlight a few places where the query I posted produces erroneous results and explain how to get good results in these places. Give concrete examples showing how to get the correct results of the sample data.
