Oracle SQL - Bug

Hi All,
I am writing this so that someone someday can take this to Oracle Corp as this is a simple bug which ought to be rectified by Oracle.
Eg: select * from emp a where a.empno in ( select empno from empl b)
Here i am using an Isolation Level 1 by using a Sub-Query to only return rows that matches with empno in table Empl but Empl table used in Sub Query does not have a Column by name empno . This should have returned an Oracle error instead it is taking the Column alias of table emp in Main Query.
Many of us here will think or presume that this is correct as when using Isolation levels but this is not happening that way . There is an Oracle Bug which ought to be rectified in their next release.

Definitively not a bug, at least bad query writing.
Use prefix should solve your problem, something like this :
select * from emp a where a.empno in ( select[b] b.empno from empl b)Furthermore, I wouldn't understand why you want, in the subquery, get the empno from the emp table instead of empl.
Here was some threads about that, please read one of them here below :
Re: Bug in Oracle 9.2.0.1.0.
Moreover, this is not because you said "many of us here" want a correction that Oracle will correct it, because that's not a bug !

Oracle SQL Developer Data Modeler 3.0 Bugs, Resolution and workarounds

The purpose of this thread is to list bugs discovered while using ORACLE SQL Developer Data Modeler 3.0
Mainly with SQL SERVER 2005 and ORACLE 10g models.

SQL Server Physical model doesn't save table identity column.
here are the steps to get this bug:
1. create a table in relational model with a column as an integer to be used as an identity.
2. create or open a physical model for SQL-SERVER 2005
3. open the table in the physical model
4. edit the integer column property dialog
5. tick the identity check box and close the property dialog
6. save the model and close it
7. open it again, you will find the identity check is removed! (probably not saved from the start)

Bug in Oracle SQL Developer

I had Oracle SQL Developer 1.5.0.53 and when I did a "Check for Update" it said no updates found, even though SQL Developer 1.5.1 was released on June 9, 2008. So obviously this is a bug you need to fix.
OK - So I downloaded the latest Oracle SQL Developer and installed it and when I opened it up, all my connections were gone!!!
That's another bug you need to fix.

See Does check for updates install 1.5.1 for some suggestions for Check for Update.
For installing 1.5.1 and then losing your connections, did you install in a new directory or over the top of 1.5.0? If yes, then reinstall again into a new directory. If not, did migrate your settings from 1.5.0? Without doing that 1.5.1 won't find your existing connections.

BUG in Oracle SQL Developer 3.0.04 on the "generating DLL" with comments?

I'm newbie on oracle, but I think that I found out a bug in Oracle SQL Developer version 3.0.04 on the "generating DLL" tool using "comments".
I will describe the steps that I gave:
I created a view, but after I test it I had to change my “where” condition, so I comment the old code and then I wrote the new “where” condition below. After I done that I tried to look at the sql code of my view using “generating DLL” tool, but oracle sql developer only shown me half of the code, a lot of code were missing. Then I began with some test trying to understand what happen and I notice that if I put an invalid sql code in my comment the generating DLL start working with no problems, for example(pseudo-code):
(COMMENT WITH VALID SQL CODE the "Generating SQL" don't work:)
CREATE OR REPLACE VIEW <user>.<view_name> ( <column1>,<column2> )
AS
SELECT column1, column2
FROM table1
INNER JOIN
(SELECT
FROM table2
INNER JOIN .....
INNER JOIN ....
--where time_stamp = (select max(time_stamp) from .....)
WHERE time_stamp >= TRUNC(sysdate)
) t1 ON t1.ID = ....
AND ..... >= TRUNC(sysdate)
ORDER BY ....
Generating DLL returns this(when the error occurs):
CREATE OR REPLACE VIEW <user>.<view_name> ( <column1>,<column2> )
AS
(COMMENT WITH VALID SQL CODE the "Generating SQL" work with no problems:)
CREATE OR REPLACE VIEW <user>.<view_name> ( <column1>,<column2> )
AS
SELECT column1, column2
FROM table1
INNER JOIN
(SELECT
FROM table2
INNER JOIN .....
INNER JOIN ....
--where
WHERE time_stamp >= TRUNC(sysdate)
) t1 ON t1.ID = ....
AND ..... >= TRUNC(sysdate)
ORDER BY ....
I believe that "Generating DLL" tool have some problem with the comments, I also used /*...*/ to comment but the problem is still active.
I notice as well that if I started to add some more comments along the code, the conditions migth change, so I think the problem is related with "comments" code.
Would you mind telling me if this is a real bug or if I'm doing anything wrong.
Thank you in advance,
Rodrigo Campos

Hi Rodrigo,
Thank you for reporting this. The only bug I see currently logged on a comment affecting the generated View DDL involves ending the last line of the definition with a comment, which treats the ending semi-colon (even if on a different line) as part of the comment. That is actually related to a low-priority bug against an Oracle database API.
Unfortunately, your pseudo-code is a bit complex. Trying a few quick, simpler tests against the standard HR schema did not reproduce the issue. I tried INNER JOIN, and nested SELECTs. It would help greatly if you could provide a test case compilable against one of the standard schema, like HR or SCOTT.

SQL Bug in "Minus" in correlated subquery presence of index (11.2.0.1.0)

SQL Bug in "Minus" in correlated subquery presence of index
(Oracle Database 11g Release 11.2.0.1.0)
Below, there is a small example that shows the bug. Further below,
there are some more comments.

create table Country
(code VARCHAR2(4) constraint countrykey PRIMARY KEY,
name VARCHAR2(35));
-- if the key constraint is not given, the bug does not occur

Select c.name
From country c
Where exists
((Select name
From city
Where city.country=c.code)
minus
(Select city
From locatedon
Where locatedon.country=c.code)
-- wrong answer: only Sweden; Spain and France not in the answer!
select distinct country from
((Select name, country
From city)
minus
(Select city, country
From locatedon)
-- correct answer: E, F, S
Comments:
The bug has been found by students in our SQL course.
Using a larger database from that course, the bug can be reproduced
(same queries as above) at
http://www.semwebtech.org/sqlfrontend/
(wrong: 142 answers, correct: 154 answers)
During reducing it to a simple sample, there were some interesting
observations: trying with smaller and simpler tables (without the keys)
and synthetic data, the bug did not occur immediately. When
restating the query after about one day, the bug occurred. Obviously,
Oracle creates some index on its own in course of its internal
optimization that (or more exactly, its usage) exhibits the bug. The
query plan (showed in SQL Developer) was the same before and after.
Wolfgang

There's a typo in the test data - GB should presumably not be in Sweden. However....
the bug did not occur immediatelyIt's possible. But what would have almost certainly happened is that the execution plan DID change at some point. There are various reasons why it might not be immediate.
Obviously, Oracle creates some index on its own in course of its internal optimizationFar from obvious, what are you on about?
The query plan was the same before and afterBet you it wasn't.
A clear illustration of the issue and indication that it must be a bug is below.
Simply by hinting a different access method, we can change the result. Therefore, bug.
See [url http://support.oracle.com]Oracle Support and search for "wrong results".
Please raise with Oracle Support to get confirmation of bug.
There have been so many wrong results bugs recently, it's getting ridiculous.
It's a real issue, IMHO.
If you can't trust the DB to get your data right....
Note that the query plan is very much NOT the same and it is the difference in query plan which s that is the root cause of the bug.

Set indention / tab size in Oracle SQL Developer

I've been poking around for an hour. Can't figure this out.
Where, either on the app's UI or in the "product-preferences.xml" file, can I change SQL Developer's indention (tab) size to 3? My organization uses PowerBuilder, and when I copy+paste our PB SQL (which uses leading tabs) into Oracle SQL Developer, it looks like crap. It would really help if I could change the code editor to a tab size equivalent to three spaces.
And no, we can’t use spaces. :-)
Thanks!
(maybe SQL Developer 2 could have a tab size field in “Preferences”)

In 1.5.x, it's under Preferences - Database - SQL Formatter - Alignment and Indentation .
However, at least in the current 1.5.3, a bug ignores the tab preferences completely, so you're stuck with the 2 spaces. If you can't wait until this gets fixed (with luck in the upcoming 1.5.4 or else maybe by 2.0), revert to an earlier version.

Oracle SQL Developer for OSX not able to compile/execute/handle packages?

Hi,
Have been stuck with this for quite some mins now,
When I execute this simple -valid- create package statement in Oracle SQL Developer:
http://www.pastebin.ca/757859
It shows it's not compiled and has errors, when I check the Packages part in Oracle SQL Developer I see this:
http://www.pastebin.ca/757860
The ; after end has been removed by the application. In fact this means I can't do anything with packages in Oracle SQL Developer for OSX?
Is this a known bug?
Or am I doing something wrong?
Any resolving response to this matter would be really appreciated.

Yeah, that bug is in there since stoneage, and is really a no-brainer to fix. Until they don't, we'd be losing time recompiling.
FWIW, everything works fine using the procedure editor for creating, editing and compiling.
Regards,
K.

Oracle SQL Developer Release 1.5.5 "compile for debug"

Using Oracle SQL Developer Release 1.5.5 on Windows XP pro machine connecting to 9.2.0.4 database on AIX machine.
Trying to debug a procedure, in the navigator window, I rt-clk the procedure and select "Compile for Debug", then nothing happens. This happens for every procedure I've tried. I've been granted both DEBUG ANY PROCEDURE and DEBUG CONNECT SESSION. Any ideas?

This is the first I've used SQL Developer, so I'll take the blame. I had not noticed that the Messages Log does in fact tell me that the proc compiled. However, the debug icon (little red bug) was nowhere to be found.
I see now that I need to Edit, not Open, the proc in order to debug. If I had read the Help screens a little more closely, I would have seen that I needed to be in Edit mode. My bad. Thanx to all for your responses.

OC4J: 10.1.2
Toplink: 9.0.4.5

Is this a problem in our oc4j with toplink and datasource configuration or perhaps a real BUG ?

Oracle.sql.BLOB.getBytes

When my application( weblogiv 12c) is trying to fetch data from a BLOB column of a table, it is getting the below exception.

I am thinking in lines of inappropriate oracle drivers. This application is currently pointed to oracle 11g database and throwing exception. However, when I swtich the database to another one (oracle 10g) with exactly the same data (to be precise, it is a replica of 11g mentioned above), it functions without any issue.
Could anyone please help me in getting through this ..

It does sound like a bug/incompatibility between drivers and DBMSes. Open an official support case with Oracle.

Oracle.sql.BLOB.freeTemporary() is not freeing TEMP space in the database

Hi Folks,
We are using oracle.sql.BLOB to store some file information into the database.
Allocation of the temp space is done as below
BLOB blob=BLOB.createTemporary(conn, false, BLOB.DURATION_SESSION); // this results in the usage of TEMP space from database
And subsequent release is done as below
blob.freeTemporary(); // this should have release the space from the database.
This is on Oracle 10g, Java 1.6, ojdbc6.jar There are no exceptions. Even a simple program results in the same.
Anybody faced something similar? Any pointers would be really appreciated.
Thanks,
Deva

Thanks a lot for the information.
Memory is fine. And I am able to reproduce this within the scope of a simple example as well.
Would you have any reference to the thread which had earlier reported this as a bug. I tried a reasonable amount of search in the forum, but no success.
Thanks very much for any pointers.

Oracle sql STRUCT query

Hi all. I have a simple program running in JDeveloper using JDBC for retrieving SDO_Geometry values from various spatial tables. The program works fine but when I run the following SQL statement to retrieve the geometry column from a table states it is returning the sdo_geometry values in the following format:
spatialQuery = "select a.geom from states a";oracle.sql.STRUCT@e2dae9,
oracle.sql.STRUCT@19209ea,
oracle.sql.STRUCT@c8f6f8,
oracle.sql.STRUCT@1ce2dd4,
oracle.sql.STRUCT@122cdb6,
I know the program works but can anyone tell me how to interpret these results or even how to translate them into a more useful format. Cheers Joe

I assume you are getting back a List (Vector) with the Struct inside it. Try ((List)query.getSingleResult()).get(0).
In JPA you should get the Struct back directly if the result size was 1, otherwise an Object[], this was a bug in EclipseLink 1.0 that was fixed in EclipseLink 1.1.
You should probably upgrade to EclipseLink 1.1.

Import data using Excel and Oracle SQL Developer - I need some help

Dear friends,
I'm using Oracle SQL Developer 1.5.1 and I need to import an Excel file into a database table. If I try to import this file in XLS format, fields and headers are correctly being shown and separated, but if I press "Next" button, it simply doesn't do anything - it stays stopped.
I did some search here in this forum and it seems to me that, when you try to import a file via XLS format, SQL Developer has bugs. Is this correct?
If I save the same file in CSV format and try to import the same file, it goes ahead, but SQL Developer is not separating fields and headers correctly. It combines all CSV fields into one - let's say Column0 and fields 1;TEST;01/01/2000 below the same Column0.
Saving the file in CSV format is not a problem, taking a very little time. But I don't know how to make SQL Developer import it correctly. Could somebody please help me? Thanks in advance.
Best regards,
Franklin

Hello K,
yes, you're right. I found the following topic after posting this question here.
Re: After update to 1.5.1, import from Excel fails
I downloaded version 1.5.0 and I'll use it whenever I import data from Excel.
Thanks,
Franklin

Issue with Oracle.sql.NUMBER in Java Stored Procedure

When we try to make a call to the Oracle.sql.NUMBER(String) inside a java stored procedure and pass values from '01' to '09', it throws java.lang.StringIndexOutOfBoundsException: String index out of range: 3
We use Oracle 9.2.0.6 - JServer Release 9.2.0.6.0.
It works fine for other values. Please find below the code used for simulating the issue outside the application. Thanks.
create or replace and compile java source named testNumber as
import oracle.sql.NUMBER;
import java.sql.SQLException;
public class TestNumber
       public static String convertNumber(String parm) {
                 NUMBER nTest;
                 try {
                         nTest = new NUMBER(parm);
                         return "TRUE";
                 }catch (SQLException sqle) {
                         return "FALSE";
create or replace function test_number (p_str in varchar2) return varchar2 as
language Java name 'TestNumber.convertNumber(java.lang.String) return
java.lang.String';
select test_number('05') from dual; - Throws exception ORA-29532: Java call terminated by uncaught Java exception: java.lang.StringIndexOutOfBoundsException: String index out of range: 3
select test_number('5') from dual; - Works fine
select test_number('010') from dual; - Works fine

Siva,
I'm only guessing, but it could be an Oracle bug, in which case I suggest checking with Oracle Support.
(You do have a support contract, don't you? ;-)
Did you try compiling and running your java class "TestNumber" outside the database?
Class "oracle.sql.NUMBER" should be in Oracle's JDBC driver, I believe.
Good Luck,
Avi.
