Oracle BUG (CASE + remote tables + inline view)

Oracle 9.2.0.8
BUG: Oracle inserts NULL when we use CASE statement in the SELECT query and we join a remote table with inline view.
Script:
CREATE TABLE t1 (a number(19,4)OK.
SELECT (case when b = 1 then c else d end)
FROM t2@Remote LEFT JOIN
(SELECT a FROM t3@Remote) q ON (t2.a = q.a)123
456
789
3 rows selected.
INSERT INTO TABLE t1 (a)
SELECT (case when b = 1 then c else d end)
FROM t2@Remote LEFT JOIN
(SELECT a FROM t3@Remote) q ON (t2.a = q.a)3 rows inserted.
SELECT * FROM t1<null>
<null>
<null>
3 rows selected
Oracle inserts the correct values if I:
* replace the CASE with DECODE
* join with table not with an inline view
* join local tables
Someone with registration in the Metalink can post the bug.
Best regards, Beroetz

Oracle errors in a table or view

Hi,
Is there any oracle table or view with all the oracle error numbers and error messages
from ORA-00000 till ORA-36804.
Please let me know.
Thanks in advance.
Sreenath.

There isn't a table, but you can create your own easily. This script displays them all but you could just as easily insert them into a table:
DECLARE
   err_msg          varchar2(4000);
BEGIN
FOR err_num IN 0..36804 LOOP
   err_msg := SQLERRM(-err_num);
   if instr(err_msg, 'Message ' || err_num || ' not found;') = 0 then
      dbms_output.put_line(err_msg);
   end if;
END LOOP;
END;
/Notice that this doesn't print errors that have no associated message.

Inline View

I am working in very important sector in Canada and using Oracle widely. There is a group of experienced managers and developer who discourage to use inline views. They have some reasons in addition to (may be misleading) information pass on by Oracle. According to them Inline views are �devils work�. It gives wrong results and poor in performance. They also refer an oracle bug, which I believe is a misleading info by Oracle (probably same guy).
http://metalink.oracle.com/metalink/plsql/showdoc?db=Bug&id=1227266
I have posted a question against that bug to Oracle (metalink.oracle.com) PL/SQL FORUM. I think Note:118978.1 is right and if we incorporate aliases we will never face problem. I have widely used inline views and never faced wrong results. In my opinion Inline views made life simple and easy. Its performance is excellent and save a lot of time rather to write multiple SQLs, which make the maintenance job difficult. Considering you an authority on Oracle. I want to seek expert opinion about Inline view. Please keep in mind that here we use lot of SQLs just to avoid inline views and some time convert some SQLs into real Views just to get rid of inline view. Your note could help me to convince my manager to allows us to use inline views.
Regards,
Amer

I need comments from other experts using metlinks but some how not getting any response.Because it's pointless. If your managers and colleagues don't trust you why the heck should they listen to a bunch of nobodies like us> You've got Tom Kyte on your side, he's the Oracle VP of database technology, he's the biggest howitzer in the field. If they go up against him they're going to be flattened.
Unfortunately there is no cure for human stupidity (I speak as a long term sufferer), and in my experience people with entrenched positions are rarely willing to admit that they were wrong. Particularly when any outsider can see that they are obviously wrong.
As I see it, you have two choices:
(1) Knuckle down, don't use inline views.
(2) Be assertive, use inline views. When challenged demand that they both prove that your implementation is buggy and provide an adequate alternative (as performant, as easy to understand, more reliable).
Be aware that if you take line (2) you must ensure your code is bulletproof: test it rigourously. By forcing them to look at the code, you can undermine their arguments with fact, an ounce of which is worth a ton of opinion.

Oracle jdbc creating a table, sequence and trigger

I'm trying to create a table with a sequence and with a trigger for that sequence. When I do this within Oracle Express edition I have the following SQL statements. Which DO run correctly inside Oracle Express using the same user I log in with JDBC.
CREATE table "TEST" (
"ID" NUMBER(10) NOT NULL,
"NAME" VARCHAR2(20),
constraint "TEST_PK" primary key ("ID")
CREATE sequence "TEST_SEQ"
CREATE trigger "BI_TEST"
before insert on "TEST"
for each row
begin
if :NEW."ID" is null then
select "TEST_SEQ".nextval into :NEW."ID" from dual;
end if;
end;
So now what I do is put each of these into a List of Strings and execute 1 by one like this:
List<String> commands = new ArrayList<String>(4);
commands.add("Create table ...");
commands.add("Create sequence ...");
commands.add("Create trigger...");
st = con.createStatement();
for (String command : commands) {
st.execute(command);
etc...
But I get an error with the trigger statement. "Error with Oracle command: ORA-00942: table or view does not exist"
It seems to me that Oracle has not yet seen the new table at this point. or maybe my user can create tables but not triggers? If that's the case why did it work in the express application itself?
TIA

If that's the case why did it work in the express application itself?No, DDL commands cause an explicit commit. As soon as you invoke them, the change is permanent. If it was a rights problem, you'd get a different ORA error stating that, it won't silently fail.
Lets not assume it is anything difficult, perhaps there is simply a typo in a name somewhere?

Best practice for VPD and remote tables

Not specifically an HTMLDB question, but here goes...
HTMLDB 1.6 on 9.2.0.4 connecting over database link (fixed username/password) to 9.2.0.4
I've currently "wrapped" access to the remote tables in views, i.e. view "T" in the HTMLDB parsing schema LOCAL_USER is defined as "SELECT * FROM T@remote"
I'd like to put VPD controls on my backend tables, but I don't get how v('APP_USER') (or even APP_USER put into an application context) would be seen by the remote database.
Should I just put VPD policies on LOCAL_USER's views and call it a day?
Thanks for input!
-John

If you implemented the VPD in the remote database, what would your VPD be restricting? All queries would apply the policy based on the DB link fixed username resulting in all users of the HTML DB application having same policy restrictions.
The policy in the remote database does not has access to the value of v('APP_USER'). That value is only available in the database that has HTML DB. You would have to write APIs in the remote database in PL/SQL functions/procedures to pass in the V('APP_USER') value to the remote database. This is doable, but cumbersome.
If you want to have your policy modify your WHERE clause on the fly based on your HTML DB user account, then I would implement the VPD in the database which has your HTML DB repository. I am not sure which of the two scenarios below occur when doing a SELECT * FROM T.
1.) The query goes across the database link, gets all the data out of table T in the remote database, passes back to the HTML DB database, and applies the policy WHERE clause modification in the HTML DB database.
2.) The query applies the policy WHERE clause modification to the view, goes across the database link with the WHERE clause modified, and gets only the data allowed based on the policy from the remote database.
You should test this out to find out for performance purposes what query is actually performed on the remote database.
As always if anyone sees anything inaccurate in what I have written, please correct me.

Developing database views between Oracle and SQL Server tables

I am on Oracle 10.2, my organization has many SQL Server databases as well and has now made
SQL server as company standard so many new databases will be developed in SQL Server. It is of course
not possible to convert all Oracle databases to SQL Server, so a mix environment will exist. Two questions:
1. Is it possible to develop database views in Oracle (10g in my case) which join Oracle tables with tables in SQL Server 2008? If yes, how. I have seen some heterogeneous connectivity setup to connect SQL Server to Oracle, but not sure whether it is possible to develop a database view across two databases.
2. I know it is not a SQL Server forum, but many DBA’s know both Oracle and SQL Server. Is it possible to develop views in SQL Server (SQL Server 2008 R2 in my case) which join Oracle 10g and SQL Server 2008 tables? I know in SQL Server, there is way to set up linked servers, but do not know whether it is possible to develop views.
Thanks a lot for your insight.

You can create views that join local Oracle tables and remote SQL Server tables. I'm pretty sure you can do the reverse as well but I haven't personally done it.
However, I would be very concerned about the performance you'd get if you created that sort of view. You'd very frequently end up in a situation where Oracle has to pull all the data in the remote table across the database link in order to apply predicates and join the data locally. That could be disastrous from a performance standpoint.

Problem encountered when join two remote tables in a materialized view

I'm using oracle 9.2.0.6
1> I have two tables:
CREATE TABLE TEST
A VARCHAR2(100 BYTE),
C DATE
CREATE TABLE TEST1
A VARCHAR2(100 BYTE),
B TIMESTAMP
2>. I defined a prebuild table:
CREATE TABLE MV_TEST1
ID1 ROWID,
A VARCHAR2(100 BYTE),
ID2 ROWID,
B TIMESTAMP(6),
C DATE
3> I created mview logs:
CREATE MATERIALIZED VIEW LOG ON PSI_TEST.TEST
WITH ROWID
INCLUDING NEW VALUES;
CREATE MATERIALIZED VIEW LOG ON PSI_TEST.TEST1
WITH ROWID
INCLUDING NEW VALUES;
4> when I create mview:
CREATE MATERIALIZED VIEW PSI_TEST.MV_TEST1
ON PREBUILT TABLE WITH REDUCED PRECISION
REFRESH FAST ON DEMAND
WITH PRIMARY KEY
AS
select
test.rowid id1,
test.a,
test1.rowid id2,
test1.b,
cast(null as date) c
from test , test1
where test.a = test1.a(+);
It is created successfully.
5> problem:
when I use remote tables to do the same thing, say test and test1 are in another instance and are connected by a dbLink, I couldn't create the mview successfully:
CREATE MATERIALIZED VIEW PSI_TEST.MV_TEST1
ON PREBUILT TABLE WITH REDUCED PRECISION
REFRESH FAST ON DEMAND
WITH PRIMARY KEY
AS
select
a.rowid id1,
a.a,
b.rowid id2,
b.b,
cast(null as date) c
from test@dbl a, test1@dbl b
where a.a = b.a(+);
when run above statement, I got:
ORA-12015: cannot create a fast refresh materialized view from a complex query
Any ideas? Or joining two table through a dblink for a mview is not allowed at all?
Thanks in advance.

No one has a clue?

Instead-of Trigger of View on a Remote Table Fails!!!

Hi all,
I'm trying to create an INSTEAD OF (UPDATE or INSERT) trigger on a view V1 in DATABASE DB1 (Linux 7.3 or 7.2, ORACLE 9.2.0.1.0 - Production).The view V1 is created on a remote table through a DBLINK.But I always get such error when I update the view V1 using statements such as "update v1 set oid=oid+1000" :
ORA-03113 end-of-file on communication channel
But I can execute those statements successfully in Oracle of version 9.0.1.0.0 .
What I want to say is that if some special configs is needed to support instead-of trigger of a view on a remote table ?

Hi Airings,
'ORA-00942: table or view does not exist'
According to the error message, it seems that the migrating table or view does not exist in the database, or SSMA does not have access to it. To troubleshoot the issue, please check the following things.
1. Verify that if the spelling of the table or view name is correct.
2. If the table or view exists but is in a different schema from the current schema where the SQL is executing (in other word, the table doesn’t own by you, but owned by other user), the ORA-00942 error will return too. Resolve this by
explicitly reference the table or view by specifying the schema name (schema_name.table_name).
3. SSMA queries some additional catalog tables that you may not have permission to, please make sure that you grant the account permission to
read sys.mlog$. For more details, please review this similar thread:

[SQL] inline view and order by on oracle 8.0.5

Hi everyone.
I am trying to sort data inside "inline view"
on "Oracle8 Release 8.0.5.0.0 - Production".
However, it did not work. Is this an oracle-bug?
I got the oracle error , "ORA-00907".
The sql script is like this:
select ..............
from (select ..... from .. where .... order by ...)
where rownum <11
However, the "exactly" same sql has no problem
on "Oracle8i Enterprise Edition Release 8.1.7.0.0".
Every response will be greatly appreciated.

Fine tuning oracle inline view

Hi All,
i have a sql query (inline view) which is taking very long time (16 mins Approx) in our environment (Oracle 8.1.7 on Sun).
Can anyone have any idea to either fine tune the query OR convert it into PL/SQL.
Query:
SELECT DISTINCT ML.MFG_LEVEL,
SUBSTR(ML.PROCESS_DESC,
INSTR(ML.PROCESS_DESC, '_', 1, 2) + 1) AS FACILITY,
SUBSTR(ML.PROCESS_DESC, 1, INSTR(ML.PROCESS_DESC, '_') - 1) AS PACKAGE_NAME,
SUBSTR(ML.PROCESS_DESC,
INSTR(ML.PROCESS_DESC, '_') + 1,
INSTR(ML.PROCESS_DESC, '_', 1, 2) -
INSTR(ML.PROCESS_DESC, '_') - 1) AS BASIC_TYPE,
BT.BATCH_TIME_MEAN / BS.BATCH_SIZE AS RUNTIME_BASE,
ML.TASK_DESC,
ML.RESOURCE_DESC AS RESOURCE_NAME,
ML.PROCESS_DESC
FROM (SELECT DISTINCT RP.VALUE AS MFG_LEVEL,
TM.TASK_DESC,
RM.RESOURCE_DESC,
PC.PROCESS_DESC

WHERE PC.PROCESS_ID = PP.PROCESS_ID AND PP.TASK_ID = TM.TASK_ID AND
TM.TASK_ID = TP.TASK_ID AND TP.RESOURCE_ID = RM.RESOURCE_ID AND
RP.RESOURCE_ID = RM.RESOURCE_ID AND
PT.PARAMETER_TYPE_ID = RP.PARAMETER_TYPE_ID AND
PT.PARAMETER_TYPE_ID = 220037 -- AREA i.e MFG_LEVEL
AND(TM.TASK_DESC NOT LIKE '%SUBCON%' OR

Please feel free to ask me for more information if needed.
Thank You.

Jawahar,
Before you run this sql statement analyse those tables which you use in that query using dbms_utility.analyse_schema() then create one Mview for that query. Before you do all this use "Explain Plan for" this query and observe the statistics. See you need to create a table for Explain Plan. You can find that script in ORACLE_HOME/rdbms/admin/utlxplan.sql

Where do i see all the default tables and views in oracle 10g

hi,
I have installed oracle 10g in the linux os.
I just wanna see the list of deffault tables and views created by oracle.
can anyoone hlep me on this
thanx in advance....

Check DBA_OBJECTS for all seeded objects in an Oracle database. For tables, check DBA_TABLES. For views, check DBA_VIEWS. All of this is documented in the fine documentation - take some time out to read thru it.
