  Hi all

  This is pavan, using Apex version 4.2.3

  
  

  I am trying to download the csv file I followed this link , and I'm able to download excel with headers, when I try to download with headers of this error "'ORA-01858: a non-digit character was found here where was waiting for a digital" I searched in google but could not find the right solution, "

  
  

  can anyone help on this please.

  Thanks in advance,

  
  

  Kind regards

  This article is 6 years old.

  You should study the solutions that are available for APEX 4.2: data loader or the 'Excel2Collection' plugin (which also manages the CSV files).

  Data Loader

  It is a wizard that generates an Assistant for your application.

  Excel2Collection

  You will use the Excel2Collection (in a single process) to convert the BLOB in a Collection

  Then, in a 2nd address), you just do a "INSERT...". SELECT statement.  Add ' where seq_id > 1 "for files with a header.

• ADF: How to manage the value zero when downloading the csv file

  Dear all,

  I'm new in the ADF and use 12.2.1. I am downloading of data in the database using af table: inputfile and CSVParser class. Data download correctly in the database where all columns are met, but whenever the csv file has value null (empty) in his column, then CSVParser class does not recognize it and get the next value of columns and assign the previous column. I also tried another one that uses a different class to download date but not get success.

  For Ex:

  ID name Dept

  1 abc Dept1

  2 cde Dept2

  3 Dept3

  In example above two first line are perfectly inserted in the table while the third line Id goes to ID column, due to the value of the column name is null class CSVParser does not recognize it and put Dept3 in the name column.

  Please help how to handle this.

  Thanks in advance.

  Kind regards

• Performance problem when downloading the CSV files into Oracle tables

  We have implemented the Vikas solution ([http://htmldb.oracle.com/pls/otn/f?p=38131:1]) to download CSV files into tables Oracle permanent and it works fine. However, whenever we try to send more than 5,000 records, it takes a lot of time and often wait times. What can we do to improve performance? We are running HTMLDB 2.0.
  
  For example, a CSV file with 12000 documents and 40 columns takes 40 minutes to load (while a recording of CSV 2000 file takes 2 minutes to load).

  For large external files, copy us our CSV files to the Oracle server and then make reference to the file in an Oracle external table. Once the external table defined you then load your APEX table via a stored procedure by using:

  INSERT INTO your_tbl (columns)
  SELECT (columns)
  Of external_tbl

  Hope that gives you another option to consider.

• ColdFusion does not recognize the CSV files

  I have a local version of ColdFusion developer 10 on my local machine.

  I use ColdFusion to create a CSV file and save it on the server and create a link by using the following code.

  Browsers open the CSV file in a text file and I use link right click to save target, my Windows Explorer save a html file.

  It works on the other server, using the same code.

  I want to know are there any which configuration to set ColdFusion recognize the format of CSV file when saving the target and he lets browsers know how to use Excel to open CSV files.

  Your information and help is much appreciated,

• Publish everything by downloading a CSV file in a form

  We have a master (M) and detail (D) registration form. The main block and can display 5 files at once (multi block)

  The recordings will be filled by downloading a CSV file from the hard drive.

  Question

  If there are 5 records in the csv file, the download works correctly. If this isn't the case, it won't be very good.

  We were wondering if there is a few BLOCKS / WEB of property should be defined, which will allow more than 5 documents to download

  Please provide your valuable suggestions

  Thank you

  "Error in the filling of the block" isn't an oracle error message. When the error appears, like her "FRM - 12345 Text". Please post the 3 initial letters and the number 5-digits of the error. Also you said nothing about your version of forms or code that you use to fill the block.

• list box given to the .csv file using write on the worksheet File.vi

  Hi, I use the write on the worksheet File.vi to write data multicolumn ListBox to the .csv file. If I do record from Excel, the pop-up window shows as an attachment. And data listbox are too different.  I want the data displayed in the first line not the second row (third photo).

  Thank you for your help.

  Before making your Save As in Excel, change the cell formatting of number. This should avoid the scientific notation conversion before you re-register.

  Or just use Notepad to display the file instead of Excel.

• Unwittingly, I asked for a way to watch the CSV files.

  I was sent to a program that is downloaded into my computer. With Vista, how can I quickly find this program and delete it. I have done nothing else in the computer, but write to you guru. Thank you very much.

  Hello DaveF1953,

  Thank you for your message.  The. The extension is CSV refers to "Comma Separated Values".  Usually (not always), it is a format that can be used for the transfer of personal and other address books.  As stated Michael Murphy, we would need to know more information before we can give you sound advice.  If you need to view the information contained in the .csv file, try to open the file with Excel if you have Office on your computer.
  We can't wait to hear back on your part.
  See you soon

• How to download the CSV from Server?

  Hello

  We have an obligation where the user must download a (.csv) file from the server by clicking a button in the OPS.

  Thank you

  Please see the update below of Oracle Technology Mukul Blog: download option giving the user of a file at a particular location on the application server

  ============================

  When you run this code in jdeveloper, jdev has its own local as application server OC4J server, so your local machine acts as a server and the way that you MENTION it, it will search in the path to your local office itself, that's why you get this error, since this file and the path that you MENTION is there on the server of real applications Oracle apps and not on your local desktop.

  Therefore, once you deploy this code on the server and run try to access this page from there, it works perfectly.

• How to write the char value as it is in the CSV file

  Hello world
  
  I create a csv files containing details of the inventory of all products. I am able to create the CSV file utl concepts. My problem starts after the csv file is being created.
  some of the product numbers (although I mean the product number, it is varchar2 data type in the table) is like this 3rd-12, 3rd-54 and so on. I have totally 23 numbers of product like this.
  When the user opens the csv file, it evolves to numbers like this 3.00E - 12, 3.00E - 54. I want to keep the product number because it is like the char value. I tried many methods of submissions and concat.
  But none of them works for me.
  
  I use oracle 9i.

  This is because in Excel, the default format for all cells is "Général" and this format is this:
  >
  Format 'Général' Converts numeric values to numbers, values from date to date, and all remaining values to text.
  >
  If you open a file with CSV extension, then each cell uses the format "General".

  You have two choices, and two of them will require the user to go through the text import wizard dialog boxes.

  Save the file with another extension, for example "txt". Then when a user opens the file they will have to select "Delimited" for the file type in step 1 of the wizard and select "next". They will then choose "Comma" as the separator at step 2 of the wizard and select "next". They must then select 'Text' to the data format column in step 3 of the wizard for these two columns, and then select "Finish".

  The other 'Data-> external data' option in the menu and involves the same selections in the wizard.

  You can chat with your users the ability to use a standard for these two columns prefix so that they will be treated as text. If you use "-" as a prefix data will display correctly.

  As mentioned, this disrupts the question, because a possible answer was published in the OTHER thread... Check your server logs, you probably delay... Preliminary discussions with a similar problem:

  Take a look at the httpd.conf file (or get your system administrator to look at it) and see what's on the value of TimeOut. You may need to increase in order to export large tables by APEX.

  Hi Like2Flex,

  The problem is that coldfusion does not see

  list = "a, b, c, d.

  as a list of 9 things you expect. He just sees 4 elements a, b, c and d because Coldfusion does not include two delimiters next to each other.

  A solution to the problem is to manually insert a space between two delimiters that are side by side. Here is an example of such a solution

  
  
  
  length of the list: #listlen (list) #
