How to diff clob
How to diff two clob? I need to highlight the difference between two clob, something like revision control diff feature. Can this be done in pl/sql or sql?
A CLOB is a large object of characters.
What sort of diff do you want to do?
A typical command line "diff" will compare a text file "line by line", but a CLOB doesn't have lines per se.
You'll probably have to write some sort of parsing loop procedure to extract whatever parts you need to compare e.g. look for line feed characters and extract parts of the clob that way to make a "line" and then compare that to the same from the other CLOB.
The tricky part comes with the diff feature of being able to look ahead (or effectively backwards) to detect inserted and deleted lines etc.
Maybe someone out there has already written something similar with PL/SQL?

Hello,
In my java programme I am picking a huge data from a file and passing it to a oracle stored procedure.
In my oracle stored procedure I pick data line by line and process and to identify a new line I use CHR(10).
The problem is, the file containing the data has data in lines but when the data is read and sent over to oracle called procedure the new line is missing and the complete data is found in one line which is very huge. Hence the processing of data fails.
In Java programme, How should I read the data from the file so that the new line or line terminator remains as it is. Or the data is read exactly as it is in the file.
Also, the Oracle stored procedure argument is of CLOB type. How to handle CLOB in JAVA, that is, pass more than 32767 chars.
Thanks & Regards,
Sanju.Your problem is that createClob() isn't implemented until JDBC 4 (which I think will come with mustang). The usual way people deal with new Clob records on Oracle is to create the record, initially, with an empty Clob, read the record back and use getClob to get the Clob, then write to that and update the record. (Pretty aweful)
A technique I've found works on Postgressql blobs and which is probably worth a try is to write your own, minimal implentation of Clob. All it needs to handle are the length() and getCharacterStream methods (all others throw UnsupportedOperationException or similar. Try feeding one of those through a setClob(). Might work, might not.
With any luck JDBC will read your stream into the LOB as part of the setClob() action. -
HOW to read CLOB and create XML file on UNIX/LINUX
Hi,
Could you please let me know, how to read CLOB using ADODB. I have column CLOB type on Oracle 9.2, with content of whole XML type. I am unable to retreive more than 4k. I use adLongVarChar. So I have written Oracle stored procedure to read the clob and create XML file using DBMS_LOB package and UTL_FILE package, still no joy.
Please help.
example of my XML file is:

ThanksHello myself,
nobody has answered my question, so now I answer myself!!
The wrong part is to read the file with "open dataset" and to create the inputstream with
p_istream = p_streamfactory->create_istream_itable(
table = g_xml_table
size = g_xml_size ).
Better ist to create the inputstream with
p_istream = p_streamfactory->create_istream_uri(
.......................PUBLIC_ID = ''
.......................SYSTEM_ID = '
applserver\I$\TEMP\Datei.XML' ).
In this way no space is needed for the file.
Best regards,
Thomas

How To Update CLOB.......... Data into Table
I am using oracle 10g and i am having a tale Content_clob having two columns id integer and lob clob
in thins table i would store the lob data as ('10 20 30 40 ....100 200.........n') n number of data's
i the piece of data would be separated by space, i want to replace the data 20 into some character aa,
but if i can ues normal replace function would replace not only the 20 it also replace the 200 too,
but my requirement is replace only the specified data not the other data(like 200 or 2000)
how update the clob valueSince we're talking 10g, have you thought about using regular expressions? Here's an example:
WITH t AS (SELECT to_clob('10 20 30 40 ....100 200.........n') col1
FROM dual
SELECT REGEXP_REPLACE(col1, '(^| +)20( +|$)', '\1aa\2')

How to convert CLOB to BLOB with SQL Developer migration wizard?
Hi,
According to our requirement, we need to only migrate data from SQL Server 2008 to Oracle 11. I use the SQL Developer 3.0.04 migration wizard to do it.
I do migration from SQL Server (database name: SCDS41P2) to Oracle (User name: HCDS41P2).
My migration steps are as below: (I need to modify the target schema, so I add the steps 2) and step 3) )
1) Do migration by SQL Developer migration wizard;
2) Remove the Converted Database Objects node from migration project;
3) Re-do convert by SQL Developer migration wizard (contains changing the target schema);
When do step 1), the DBO_SCDS41P2 user is created automatically. CLOBTOBLOB_SQLDEVELOPER procedure is also created in this user.
I continued to run step 2) and step 3) with online mode. And find the table data which contains BLOB column can be moved into the target table. But from the Logging Page, I can't see the other detailed error info, so that I can't check which tables don't move data successfully.
Could you please tell me where the detail log file (e.g. contains every table's migration status) is if I use the online mode?
Additional, If I use offline mode to do step 3), I found the CLOB data can't be converted into BLOB automatically. Because in the load script (that is oracle_ctl.bat), only copy the source data to the CLOB column. After copy, it don't deal with the converting from CLOB to BLOB.
So could you please tell me how to convert CLOB to BLOB with offline mode?
Thanks so much.Hi,
For your first question about logging - after the migration there will be an entry in the right hand panel for the migration project. If you open this there are various fields that give information about the status of each part of the migration. Does this give you the information you need ?
For the second problem about offline moving blob data have a look at the SQL*Developer documentation -
Oracle® SQL Developer User’s Guide Release 3.0
in the section -
2.2.8.1.4 Populating the Destination Database Using the Data Files
which describes the problem and how to get round it.

Mike

How to seprate clob in dofferent variables?
how to seprate clob in dofferent variables?
I have clob with % and ^ sign.
I want to seprate with ^.Why do you explicitly mention the % sign? Doesn't seem to be of any relevance here.
In 11g (because of regexp_count) you could do sth like:
SQL> declare
cl clob := to_clob('abc%^def^ghfi%^jkl');
arr sys.odcivarchar2list;
begin
select regexp_substr(cl, '[^^]+',1,level) bulk collect into arr from dual connect by level <= regexp_count(cl, '\^') + 1;
for i in 1 .. arr.count loop
dbms_output.put_line('arr('||i||')=' || arr(i));
end loop;
end;
arr(1)=abc%
arr(2)=def
arr(3)=ghfi%
arr(4)=jkl
PL/SQL procedure successfully completed.Similar solutions exist for lower db versions. -
Hi,
I am using PHP4.4 and Oracle 10g for my research work. I defined 'protein_seq' field as CLOB in a table. I uploaded data into it using sqlloader.

$s4 = OCIParse($conn, "select * from protein_uniprot where uniprot_id LIKE '$protein%'");
OCIExecute($s4, OCI_DEFAULT);
while (OCIFetch($s4)) {
$proteinseq = OCIResult($s4, "PROTEIN_SEQ");

How to differ ammount and paid amount
Hi ALL,
how to differ ammount and paid amount IN A/R INVOICE
BSID-DMBTR THIS IS AMOUNT, LIKE THAT TABLE FIELD PAID AMOUNT TABLE FIELD.
THANKS
RAMHere is two way.
Normally SAP will store the amount document before clearing(paid) and after clearing in different table.
E.G. for the vendor payment invoice, before clearing is stored in BSIS, after clearing it stored in BSAK.
And you can also differentiate them by BSEG.
Check the field BSEG-AUGDT BSEG-AUGCP BSEG-AUGBL will be filled after clearing. And if BSEG-XRAGL set, this clearing has been cancelled.
hope it will be helpful

I would like to know how to differ tax currency with document currency in SAP contract.
Thanks and Regards
Vikram.MHello Vikram,
The document currency will be that of local currency. the tax currency should be of the customers country currency.
Perhaps you have to define different condition tables by passing on the fields to header or Item Level and depending on the customer Master currency detrmine Tax in different currecny. KNVV-WAERS.
This needs a bit of ABAP effort,and minor enhancement to take consideration of exhange rates. -
How to Passing clob to PL/SQL pipeline function
I have a PL/SQL stored function which takes clob as input parameter and sends the results in a pipe line.
create or replace function GetIds(p_list clob, p_del varchar2 := ',') return ideset_t pipelined is
I am using ojdbc14.jar (Oracle 10g driver) with oracle 9i (9.2.0.1.0).
I want to use the following SQL Query select * from table(GetIds(clob))
Now the question is how can I pass the clob from JDBC?
Here is my client code
PreparedStatement stmt = con.prepareStatement("SELECT COLUMN_VALUE FROM TABLE(GETIDS(?, ','))");
stmt.setCharacterStream(1, new StringReader(str), str.length());
stmt.executeQuery();
I get the following error when I try to run the program. The same thing works fine if the chracter lenght is less than some chaaracters.

Exception in thread "main"
The setChracterStream works for any insert/update clob. Example when I tried the query (INSERT INTO CLOB_TEST VALUES(?)) setCharacterStream just works fine.
Please any one can help me how to solve this.
Thanks in advance.Hóla LuÃs,
when you pick the PL/SQL function body returning a boolean, it implicitly means that TRUE means OK, while FALSE means error, always.
In order to associate such error to a given form field, you have to go back to the page definiton / validations and specify the name of the item in the corresponding field.
When you first create the validation rule, this value is not present even if you ask for the error message inline with the field.
The error message text can be specified in the validation definition, if I am not wrong.
When you need to return special error messages, including dynamic content for instance, you can use the Function Returning Error Message type, which reports an error when the string returned by the function is not null. This comes in handy when you want to display an item's code, for example, rather than generic text.
Even in this case, you must go back to the validation and specify the name of the field if you want to see it inline.
Hope it helps,
