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!

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 have a user requirement to convert oracle standard report (Transaction Historical Summary)'s output into Excel
I have tried to change output to xml to get the xml tags so to make rdf but it ends in error.
What are the steps to convert a standard report's output to excel?
You'd use Report Builder's DESFORMAT=SPREADSHEET parameter; it works for Reports 10gR2 onwards.
Here's a tutorial which shows how to do that: "Building a Report for Spreadsheet Output" (https://docs.oracle.com/cd/B14099_19/bi.1012/b13895/orbr_paptoexcel.htm).
It doesn't make sense to copy/paste all those steps over here, so - have a look, follow the instructions.
If you're on lower version, you'd create a CSV (comma-separated-values) file (choose any delimiter you want, such as comma or semi-colon). Although it is not a XSL(X) file, Excel is capable of opening it nicely.
I've been working with Oracle UCM.
All I have to do is to scan some documents, copy those pdf files in the Oracle Content Server, and then I should have access to the site and be able to search those files with their respectives names.
So far so good, but here's where things comes ugly.
Once I'm done searching one file, the UCM site doesn't show me the real name, the one that I gave to the scanned pdf. The site shows the name "sitios" ( "sites" in spanish, I'm in a latin country) instead of the name I gave it in the first place.
Usually files will be stored in two places in file system .
One will be vault location . File will be stored as it is .
Usually file name will be
dID.extension
.
Second will be in weblayout location . File will be stored as web view able version .
Usually file will be stored as
dDocName.extension
If you want to know the original file name in UCM search result , then try to get the
dOriginalName
metadata
I'm trying to write an update sql statement in postgresql (pg commander) that will update a user profile image column
I've tried this:
update mytable set avatarImg = pg_read_file('/Users/myUser/profile.png')::bytea where userid=5;
got ERROR: absolute path not allowed
Read the file in the client.
Escape the contents as bytea.
Insert into database as normal.
(Elaborating on Richard's correct but terse answer; his should be marked as correct):
pg_read_file is really only intended as an administrative tool, and per the manual:
The functions shown in Table 9-72 provide native access to files on the machine hosting the server. Only files within the database cluster directory and the log_directory can be accessed.
Even if that restriction didn't apply, using pg_read_file would be incorrect; you'd have to use pg_read_binary_file. You can't just read text and cast to bytea like that.
The path restrictions mean that you must read the file using the client application as Richard says. Read the file from the client, set it as a bytea placement parameter in your SQL, and send the query.
Alternately, you could use lo_import to read the server-side file in as a binary large object, then read that as bytea and delete the binary large object.
pg_read_file can read the files only from the data directory path, if you would like to know your data directory path use:
SHOW data_directory;
For example it will show,
/var/lib/postgresql/data
Copy you file to the directory mentioned.
After the you can use only file name in your query.
UPDATE student_card SET student_image = pg_read_file('up.jpg')::bytea;
or can use pg_read_binary_file function.
UPDATE student_card SET student_image = pg_read_binary_file('up.jpg')::bytea;
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.
