Conversion/extraction of CLOB
Hello.We are able to insert CLOB in the database, using oracle Text I'm able to search inside clob.
[two issues resolved]
The question arises when we need to send these data to demand either as text (varchar2) file.
I'm able to generate files of CLOB using the function, unfortunately it is located inside the db and developer is not able to access.
1) there is a possibility to mount the partition of application inside the db and export the file there, but this isn't a viable option according to the direction.
(2) I google the solution to create a JAVA API. Who will perform the command OS like scp to send file to db to app (or any remote host).
For security reasons, this option is also removed.
(3) I tried dbms_lob.substr but text inside clob is too long. File generated from CLOB size about 5 MB.
So I guess it takes a lot of effort if I wanted to convert in varchar2 as parameter inside the exit function.
So, to give CLOB data developer under file or varchar2. I'm not able to get any solution.
Y at - it another option using database to convert to string/varchar2 CLOB?
Or do I need to dig more into the third option.
I have oracle 10.2.0.5.
Kind regards
Dave.

I use version oracle 11g.

Another look: the CLOB is transformed in a way that allows for handlng as an xmltype.
Your particular case, it's that you are having just a single column (your | $| is Chr (10) in the solution) and you should get a result set single column to be processed according to your needs (you might be more comfortable to add a line number using keyword ordinalite to maintain order CLOB)

What I'm trying to do is
(i.) pass a value of xml string to the Oracle query variable

Approach:
Input variable type is CLOB and then running the petition below:
declare
TestXML clob.
Start

end;
Problem:
The request as written above wake up a digital error or value to sys.xmltype (ORA-06502 & ORA-06512). But if I declare the testxml as varchar2; It works very well. Searched wrong, but without success.

Easily accessible images AVI - BMP Conversion extraction
Hi, Im at a roadblock now, I have to extract frames of an AVI video then convert BMP images and load/apply a texture to an object in a 3D scene. Now the problem is not extract frames, Ive managed to extract the images using the available screws of AVI IMAQ but Im stuck after that.
I found the 'writing BMP file' VI under the utilities of Vision, one of the terminals of the VI says 'File path' which means the way he's going to write the file is now? Or...?
Secondly, I can't find a way to load/save lots of BMPS at the same time. The texture that I apply to the object comes to a BMP image (and in this case, a lot of BMP images extracted from AVI video) just by using the "Read file BMP" vi, which leads to the directory/path of the BMP on the PC. This is where the problem lies, I need the vi 'Read BMP file' was updated constantly, every 'x' seconds to account for the number of frames / FPS of the video then she reads each frame of the video as its update. But if I need to save the accquired executives AVI MPG I don't see a way to do this.
Any suggestions would be greatly appreciated.Hi again
I hope that your application is on the right track now. I found other examples for the avi feature, so I'll add the links below.

Hello
I wonder how to deal with a clob field in a JSON object that is returned by a web service. It consists of 3 - number, varchar2, and clob fields and looks like this:
{"MyNumber": 10}
'MyVarchar2': ' application/pdf ',.
{'MyClob': 'JVBERi0xLjQKJeLjz9MKMyAwIG9iago8PC9GaWx0ZXI'}
Its very easy to take the first two values using built-in functions, but I have no idea how to do to extract the clob value. My code is as follows:
DECLARE
v_response_clob CLOB; - the entire web service responsev_my_number NUMBER;
v_my_varchar2 VARCHAR2 (100);
v_my_clob CLOB.
BEGIN
-Select clob from collections of apex
SELECT c.clob001
IN v_response_clob
Of apex_collections c
WHERE c.collection_name =: PX_MY_COLLECTION_NAME;
-parse response clob
apex_json. Parse (v_response_clob);
-get my number
v_my_number: = apex_json.get_number (p_path = > "MyNumber");
-My varchar2
v_my_varchar2: = apex_json.get_varchar2 (p_path = > 'MyVarchar2');
-now how to get the CLOB?END;
Any help would be much appreciated.
Thank you very much

Edit: I forgot to mention that I use 11g XE, so the new JSON 12 c functions are not available and 5 APEX (which is actually quite obvious because of the APEX_JSON package).
Hahaha,
This is a known issue (well documented):
20974582 - apex_json.parse errors when parsing CLOB if DB Version<>
If your version of the database is 11.1.x, 11.2.0.1, 11.2.0.2 or 11gXE, apex_json.parse may report errors during parsing of a clob.
Solution: There is a group exception of fixes for this available on My Oracle Support - search by 20931298bug number. If you use ADR (Apex Listener), restart after installation of the patch.
Workaround: If you have not installed the patch, you can use the overloaded analytical procedures that take varchar2 or table of varchar2 rather.
Here

is a nice article on this subject.

Getting ORA-22835: buffer too small for to CHAR CLOB or BLOB to RAW conversion in my ODI interface
Hi all
I am creating an interface ODI as explained below,
I table A column 'Comments' and one other table with column B "No Comment." I create a view as shown below and use it as a source for my interface.
SELECT * FROM WC_EQM_CSAP_FS_TMP WHERE to_char (QUESTION_COMMENT) IN (SELECT NO_COMMENTS FROM WC_EQM_NO_COMMENTS_LIST).
But my interface fails with the error below
ORA-22835: buffer too small for to CHAR CLOB or BLOB to RAW conversion (real: 4108, maximum: 4000)
22835 00000 - "too small buffer tank CLOB or BLOB to RAW conversion (actual: %s, maximum: %s)) '
* Cause: an attempt was made to convert CLOB to CHAR or BLOB to RAW, where
LOB size was larger than the buffer for CHAR and RAW limit types.
Note that the widths are reported in characters if characters length isadds are in effect for the column, other widths are
in bytes.
Here QUESTION_COMMENT is of type CLOB data. NO_COMMENTS is also CLOB data type. The maximum length of the data of QUESTION_COMMENT is also 11710
Please tell us how to solve.
Thank you
Dany
IMHO, it is not good to compare CLOB, can be that it is possible to use the primary key for the comments
Is it QUESTION_COMMENT and NO_COMMENTS a PRIMARY INDEX,
may be is the best solution to create vacabulary with comments (if it does not exist) and then compare it by id;
You can simply use the left join and check for null in a CASE statement
Try this, but I don't know... as I said before I have no Oracle DB

How to extract a value of sql xml column clob data
Hi guys,.
I need help with the following. I have a column with data type xml (clob data). I need to extract the information in the < RI4 > tag and the < RI6 > tag.
I truncated the data, but there is a repetition of the < RI4 > tag and consequenty internal to that tag RI6. However, each tag RI4 and RI6 has different data.I would be grateful if you can help me with this:

I think that since it's the repetition I might need to make some sort of PL/SQL programming, but I really need help here to build this announcement also a way to extract the information.
Any help would be greatly appreciated.

PDF to Word conversion and extract pages
I bought the program of conversion of PDF to Word, but is not copy graphs. All I have to do is extract pages of a large file to separate them. I have that drive. Nothing, I see works online.
Hi theresadrj,
Subscribe only for services to export in PDF format, which is used to convert PDF files to supported file formats.
In order to use the pages of the excerpt from a PDF file you need Acrobat application (Adobe Acrobat free trial downloadversion |) Acrobat Pro DC), check this tutorial document split split a PDF | Adobe Acrobat DC tutorials.
Kind regards

CLOB DataType: conversion with loss when migrating to WE8ISO8859P1 to AL32UTF8
We have an application data in a database of output 9.2.0.8 (characterset WE8ISO8859P1).Now, the data must be migrated in a 11.2.0.3 output database (characterset AL32UTF8).
When you run the CSSCAN utility on the target (9.2.0.8) database I get the following result:
Table: MASTERCONTENT
Column: INFO
Type: CLOB
Number of Exceptions: 116
Size of data Conversion MAX Post: 1489532ROWID Exception Type size cell Data (first 30 bytes)
------------------ ------------------ ----- ------------------------------
AAA4jBAAKAAACRcAAA conversion with loss
AAA4jBAAKAAACRcAAB conversion with loss
AAA4jBAAKAAAvNqAAA conversion with loss
AAA4jBAAKAABg0nAAC conversion with loss
AAA4jBAAKAABg0nAAE conversion with loss...
From my understanding CLOB objects can store up to (4 gigabytes-1) * (the value of the LOB CHUNK storage parameter)
data of type character. Or is the problem that can not get the characters of certain lines converted AL32UTF8?
Currently, I do not understand why "lossy conversion" will happen...
Any help will be appreciated!

"Lossy conversion" means that some codes of characters (bytes) the CLOB listed are not recognized as valid in WE8ISO8859P1. These codes are usually in the range 0 x 80-0x9f. You must take a look at these codes and try to guess what is their true meaning. In most cases that meet Oracle customers, these illegal WE8ISO8859P1 are actually codes of WE8MSWIN1252 (WE8MSWIN1252 is a binary superset of WE8ISO8859P1). The solution is then to set the source game the good character of characters in database value and then export.
Thank you

extracting data from the CLOB using materialized views
Hello
We have xml data from clob which I have a requirement to extract (~ 50 attributes) on a daily basis, so we decided to use materialized views with refreshes full (open good suggestions)
A small snippet of code
CREATE THE MWMRPT MATERIALIZED VIEW. TASK_INBOUND
IMMEDIATE CONSTRUCTION
FULL REFRESH ON DEMAND
WITH ROWID
AS
SELECT M.TASK_ID, M.BO_STATUS_CD, b.*

REVENUE_CLASS varchar2 (10) PATH "cmPCCustomerAgreement/revenueClassCode"
REQUESTED_BY varchar2 (50) PATH ' attributes customerInformation/contactName',...~50
This ddl ran > 20 hours and no materialized view created. There are certain limits that we have
- Cannot create a materialized view log
- cannot change the source as its defined provider table
- cannot do an ETL
DB is 11g R2
Any ideas/suggestions are very much appreciated
I explored a similar approach, using the following test case.
It creates a table "MASTER_TABLE" containing 20,000 lines and a CLOB containing an XML fragment like this:
09HOLVUF3T6VX5QUN8UBV9BRW3FHRB9JFO4TSV79R6J87QWVGN UUL47WDW6C63YIIBOP1X4FEEJ2Z7NCR9BDFHGSLA5YZ5SAH8Y8 O1BU1EXLBU945HQLLFB3LUO03XPWMHBN8Y7SO8YRCQXRSWKKL4 ...

SQL > create table master_table like
2. Select level as id
3, cast ('ROW' | to_char (Level) as varchar2 (30)) as the name

Materialized view created.
The discount is then performed in two steps:
- INSERT INTO master_table_xml
- Refresh the MVIEW
(Note: as we insert in an XMLType column, we need an XML (only root) document this time)
