How to view a BLOB data, can i export it to text file? I am using Oracle SQL developer 5.1. When i tried
select utl_raw.cast_to_varchar2(dbms_lob.substr(COLNAME))
from user_settings where <fieldname>=...
It returns the following error: ORA-06502 PL/SQL : numeric or value error : raw variable length too long
The BLOB contains text in XML format.
To view xml data stored as a BLOB, do the following;
Open the table view, with the Data tab selected
Double click on the column field value, and a pencil button should appear in the field. Click the pencil button.
The Edit Value window should open, click checkbox for 'View As: Text'. From this window you can also save out any particular file data you require.
PS: I'm running Oracle SQL Developer version 3.1.05
Cause it over the size of the display field. It needs to set the size
You add 1500 for the substr, it should be work.
select utl_raw.cast_to_varchar2(dbms_lob.substr(colname,1500))
from user_settings where <row_id>=...
BLOB data is typically just... a binary blob of data.
Sure, you can export it to a text file by converting it to some kind of text representation... But what if it is an image?
jaganath: You need to sit down and figure out what it is you're dealing with, and then find out what it is you need to do.
You could look at DBMS_LOB.CONVERTTOCLOB
But if it is XML, why store it in a BLOB rather than an XMLType (or CLOB)
From the error message it seems that the blob length is too long to fit into a varchar. You could do the conversion in your application code and write the XML into a String or file.

Hi i have found some video and text on how to do this but they dont help with this task.
I know how to get one values but not extract a table.
I want this to get exported into a database if possible or a Excel. But i cant figure it out.
I have even tryed change the "Change reading opption"
I tryed to "data scraping" but the program just say
"This controler does not support data extraction"
And it can't be more of a table then this.
I have heard that it cant be because the structure of the PDF is bad.
Still isn't there more ways of doing this.
Unfortunately, there is no activity in UiPath to read tables directly from PDFs. (As of today.) That was the bad news. The good news is that you can get to the contents of the PDF. Either you get the data (as flat text) directly with UiPath.PDF.Activities.ReadPDFText or you have to use OCR.
#kwoxer provided a wonderful link for explanations on this topic.
I have already been able to extract data from tables contained in a PDF document. At that time, I was lucky: ReadPDFText extracted everything. The table elements were separated by tabs ("\t"). And the table header contained a word that did not appear elsewhere in the document.
Just as an idea, I proceeded like this:
Extract text from the PDF document with UiPath.PDF.Activities.ReadPDFText.
Create an array, where the elements are the lines in the document. (Split using Environment.NewLine and option StringSplitOptions.RemoveEmptyEntries)
Go through lines in a loop (ForEach) until the table header is found. (StartsWith or Contains etc.)
The next row belongs to the table as long as it contains a tab. (Otherwise the table is over.)
Split current row by tab and store it in an array: The elements of the array are the individual cells of the row.
I hope, this idea help.
I am working on Odoo12, I read in https://apps.odoo.com/apps/modules/8.0/product_image_filestore/ that images are store in filestore in later version of Odoo. i.e.9-13.
If that is true then why there is field db_datas in ir_attachment table. It is showing binary_data in this column. Although there is store_fname in this table having file path. Is odoo storing both informations binary form and filepath of image? Will not it increase the size of database?
PGADMIN show "NULL" value of db_datas as "<binary data>". If you do "select query" or view this lines in phppgadmin, you'll see "NULL".
How to read an excel sheet and put the cell value within different text fields through UiPath?
I have a excel sheet as follows:
I have read the excel contents and to iterate over the contents later I have stored the contents in a Output Data Table as follows:
Read Range - Output:
DataTable: CVdatatable
Output Data Table
DataTable: CVdatatable
Text: opCVdatatable
Screenshot:
Finally, I want to read the text opCVdatatable in a iteration and write them into text fields. So in the desired Input fileds I mentioned opCVdatatable or opCVdatatable+ "[k(enter)]" as required.
Screenshot:
But UiPath seems to start from the begining of the Output Data Table whenever I called for opCVdatatable.
Inshort, each desired Input fileds are iteratively getting filled up by all the data with the data stored in the Output Data Table.
Can someone help me out please?
My first recommendation is to use Workbook: Read range activity to read data from Excel because it is quicker, works in the background, and does not require excel to be installed on the system.
Start your sequence like this (note the add headers property is not checked):
You do not need to use Output Data Table because this activity outputs a string containing all row items. What you want to do instead is to access the items in the data table and output each one as a string in your type into, e.g., CVDatatable.Rows(0).Item(0).ToString, like so:
You mention you want to read the text opCVdatatable in an iteration and write them into text fields. This is a little bit more complex, but i'll give you an example. You can use a For Each Row activity and loop through each row in CVDatatable, setting the index property if required. See below:
The challenge is to get the selector correct here and make it dynamic, so that it targets a different text field per iteration. The selector for the type into activity will depend on the system you are targeting, but here is an example:
And the selector for this:
Also, here is a working XAML file for you to test.
Hope this helps.

Here's a different, more general approach. Instead of including the target in the process itself, the Excel would be modified to include parts of a selector:
Note that column B now contains an identifier, and this ID depends on the application you will be working with. For example, here's my sample app looks like. As you can see, the first text box has an id of 585, the second one is 586, and so on (note that you can work with any kind of identifier including the control's name if exposed to UiPath):
Now, instead of adding multiple Type Into elements to your workflow, you would add just a single one, loop over each of the datatable's row, and then create a dynamic selector:
In my case the selector for the Type Into activity looks as follows:
"<wnd cls='#32770' title='General' /><wnd ctrlid='" + row(1).ToString() + "' />"
This will allow you to maintain the process from the Excel sheet alone - if there's a new field that needs to be mapped, just add it to your sheet. No changes to the Workflow are required.
I am newbie in Oracle Forms. I have stored a PDF file in an Oracle database; now I want to read that PDF file and display the content in text field in Oracle Forms.
How should I go about doing this?
Oracle Forms cannot natively display a PDF. If you are storing the actual contents of the PDF in the database, you can look into developing a PJC that leverages an existing Open Source PDF presentation layer, and embed it in the Oracle Form. You would then need to stream the contents of the database into the PJC, which would be tricky (but not impossible).
Your better bet would be to build a small PL/SQL package that can be accessed from a DAD to serve up the document, and fire off a web.show_document call to the URL from Oracle Forms.
There is no built-in to do this.
But if you dont have to use the content of the PDF anywhere
i.e you just want to see the contents of the PDF then you may try this : ( **webutil utility required)
vboolean := webutil_file_transfer.DB_To_Client_With_Progress
( 'D:\files\abc.pdf' , --location of the file with extension
'table_nm', --table name
'field_nm', --field which contains ur PDF
'sr_no=1' , --fetch the PDF of row where sr_no =1
'Downloading from Database',
'Wait to Complete');
client_host('cmd /c start '||vfilename1); --open the file
If you want to make it generic, you can store the extention, append it to the file_nm i.e
1st parameter of DB_To_Client_With_Progress(), then you will be able to open any type of document stored in the database!
I am creating a report in BIRT. My problem is a data set value which I am putting inside a table column. The returned value is a sentence, but in my report that column is showing only the first word. How can I break the line of the column to show the full data?
Try to use Dynamic Text instead of Data field, which I assume you were using.
As expression write something like row["MY_COLUMN"].
