I'm trying to fetch out clob data from a table.
In ORACLE SQL DEVELOPER, when am trying to execute a query, its displaying "..." at the end beyond 3800 characters. Could you please help me here to fetch out complete data?
Ex:
select data_clob from sample
Note:
I have tried to use dbms_log.substr as well. but still the error persists.
I have tried to set buffer as well but keep on saying its "skipped."
So please let me know if anyother possibility.

I have created a temporary table in oracle sql developer but I forgot to save it and now I want to reuse the query but I don't remember the code used then. Is there a process to get query used creation of temp table?
You can use dbms_metadata.get_ddl()
select dbms_metadata.get_ddl('TABLE', 'YOUR_TABLE_NAME_HERE')
from dual;
The result is a CLOB with the complete DDL. You might need to adjust the display in SQL Developer to make the content of that value fully visible (I don't use SQL Developer, so I don't know if that is necessary and if so, what you would need to do)
Edit:
It seems SQL Developer can't display the result of this query properly unless you use the "Run Script" option. And with that you need to use a SET LONG 60000 (or some other big number) before you run it, to see the complete source code:
I have an interface which is a simple receiveport mapping sendport. The receiveport is the result of an add generated items query. The query just fetches some adres data from the database. This data does contain 'foreign' letters but when i run the query on Oracle SQL Developer, it works fine (gives me 12800 rows).
When BizTalk runs the query, it gives an ORA, which i assumed was an error the db gives to BizTalk am i wrong?
Where do i actually have to fix this problem? and How? Do i need to find out which character set is used on the database and use a convert in the query?
This is an error coming from Oracle - it's very unlikely that it's due to BizTalk or the WCF adapter. It indicates you have some corrupt data in your Oracle DB. You may not be getting the error in SQL Developer because SQL Developer is only returning the first ~50 rows by default (until you actually scroll down past them).
I'd use a strategy like this: http://vibhork.blogspot.com/2011/02/fix-of-ora-29275-partial-multibyte.html to try to find the bad data (e.g. page through the rows using ROWNUM until you find the row that's in error) - you could simulate that in SQL Developer by just scrolling down until you get the error (I think). If you can fix the data, fix it - if the data was put there by another source, you'll either have to get that source to stop putting invalid characters in there or you'll have to convert/concat the column(s) that is (are) causing problems, like:
SELECT problem_column || '' FROM table
or
SELECT CONVERT(COLUMN NAME,'NLS_CHARACTERSET','NLS_CHARACTERSET') FROM table
You might try SELECT CONVERT(COLUMN NAME, 'UTF8', 'US7ASCII') for example.
I'm trying to move data in between two oracle databases say SOURCE_A and DEST_B. I have created a dblink (LINK_A) using TOAD on DEST_B to SOURCE_A to copy data from the tables. Dblink creation was fine, but when I used a select statement like below, I see no data except column names.
SELECT * FROM TABLE_A#LINK_A;
Could you please help me understand what am I doing wrong or missing here. I tried running a DESC on the TABLE_A using the link and it worked fine. Not sure why its not pulling any data from the SOURCE_A database.
Any help is greatly appreciated. Thanks.
Alright, with many trial and errors, I managed to get a solution that works for me in this SO question.
I used the technique provided by - Jeremy Scoggins and it worked like charm. I was able to move data using toad and its perfect. Thanks to all of you for your time and support.
Appreciate it.
Overview: Need to read row from Oracle view and create a Notes document, save document, then write Document Unique ID back to Oracle.
I am able to read connect and read data no problem. I am using a type 4 connection connecting to an Oracle 11 database. The Oracle view is setup to allow Updating. The view has nothing in it that is outline here: In Oracle, is it possible to INSERT or UPDATE a record through a view?
*With the same username and password, you are able to successfully update view by typing in SQL statement.
*Tried using conn.setAutoCommit(false); This had no effect.
*Verified that the result set was updatable (1008)
*User has been given full DBA access (temporarily)
*I have tried every possible combination of the first parameter in the createStatement method
...
Statement statement = conn.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_UPDATABLE);
ResultSet rs = statement.executeQuery(fetch);
...
String UNID = doc.getUniversalID(); //gets unique id from saved Notes Document
System.out.println("This is what to write to Oracle:" + UNID);
System.out.println("is updatable=1008, not updatable=1007 value is:" + rs.getConcurrency());
System.out.println("is Result Set Closed:" + rs.isClosed());
rs.updateString("NOTES_DOC_ID", UNID);
System.out.println("got past updating NOTES_DOC_ID column");
rs.updateRow(); //fails here
Here is the error from console:
This is what to write to Oracle:BF8091259610C61B87257B16005C14FB
is updatable=1008, not updatable=1007 value is:1008
is Result Set Closed:false
got past updating NOTES_DOC_ID column
java.security.AccessControlException: Access denied (java.lang.RuntimePermission exitVM.0)
Prior to asking for the user to have DBA access I would get a
java.sql.SQLSyntaxErrorException: ORA-01031: insufficient privileges
I think this a big clue. My DBA doesn't know what further access to give me.
The DBA is wanting me to start using ref cursors, which is fine, but I suspect there is some kind of security setting for JDBC access that is tripping me up, and I want to explore that first. If there is a security issue, then I don't think changing the way I read the rows is going to make a difference. Most of all the documentation on how to do this was obtained from Oracle's website, as well as this site.
I am going to answer my question and explain how I got past this roadblock. In the end, I basically did what 'a_horse_with_no_name' suggested.
Instead of using the resultSet cursor or a ref cursor to perform the update, I was able to use a plain UPDATE statement. This was possible, because I was able to convince the DBA to create a column for a unique identifier. We could never get around the exceptions caused by the updateRow() method of the resultSet. Prior to him adding the unique identifier, there was not a key in which to reliably use the UPDATE statement.
Here is the code where updateSQL is a string holding the update SQL statement:
updateResultInt = updateStatement.executeUpdate(updateSQL);
It returns a 1 if successful.
One word of caution, if you are using a tools like TOra or sql plus to check your update statements, you have to remember to manually commit them. If you don't your java agent will hang when trying to run it. Here is an good reference that helped me with that issue: SQL Update hangs Java program
Thanks to those who commented!
I have a weird problem right now that if a ref cursor returned from a stored procedure that has only 1 record in it, the fetch operation will hang and freeze. The stored procedure execution was really fast, just the fetching process hangs. If the ref cursor has more than 1 record, then everything is fine. Does anyone have similar issues before?
The Oracle server is 11g running on Linus. The client is Windows Server 2003. I'm testing this using the generic Oracle sqlplus tool on the Windows Server.
Any help and comments would be greatly appreciated. thanks.
When you say hangs, what do you mean ?
If the session is still active in the database (status in V$SESSION), then it is probably waiting on some event (eg SQL*Net from client means it is waiting for the client to do something).
It may be that the query is taking a long time to find that there aren't any more rows. Consider a table of 10,000,000 rows with no indexes. The query may full scan the table and find the first row matches the criteria. It still has to scan the next 9,999,999 rows to find that they don't. That can take a while.
Since you are saying that the process hangs, Is there a chance that your cursor does a "select for Update" instead of "Select " ? Since you are saying that the fetch of multiple records does not cause this error, that might not be the case.
Can you show us the code (or a reproducible small test/sample) for your select and the fetch.
Also, you can check the v$locked_objects using the following query and giving in your table name(s) to see if the object in question is being locked. Again, unless your current query has "for update" this fetch should not hang.
select do.*
from v$locked_objects vo,
dba_objects do
where vo.object_id = do.object_id
and vo.object_name = '<your_table_name>'
