Perform an Inner Join in Oracle 8

We have to make our application (that runs with Oracle 9i) backward compatible with Oracle 8.
There are certain SQL statements that were introduced in Oracle 9i, such as Inner Join (Oracle 9i now allows more of the ANSI standard SQL that MS SQL also uses)
Does anyone know of the other differences I should look out for, or any documentation that lists the new 9i differences that we may already be using.
I have trawled through lots of OTN documentation, but not been able to find anything that highlights even the Inner Join problem.
If there are any documents that also suggest a solution, that would be even better.
Thanks in advance for any help/suggestion
Mark

You have a parameter called "COMPATIBLE", and if you set to, for example 8.1.7 in your 9i database, then your application should be compatible with 8.1.7. It is that easy!
Of course, by doing so, you renounce to use the 9i features.
There is a book called "New Features" in the book list in your oracle documentation.

Delete using joins in Oracle 10g

Hi All
I am trying to delete rows from a table by comparing the criteria required with the rows in different tables..
The select statement below works fine...But when I use it for delete as shown in the subsequent SQL statement it errors out stating "SQL Command not properly ended"
Can anybody provide suggestions?....
This works fine

Help:Nested Inner Join

Hello Folks,
I have a query which has a nested Inner Join as follows
INNER JOIN(Client
INNER JOIN CUBS SNAPSHOT ON Client . Client = CUBS SNAPSHOT . CLIENT) ON CancelDesc . CancelReason = CUBS SNAPSHOT . CANCELREASONcouldnt figure out wat is the quivalent of this nested inner join in Oracle Server. I am trying to create a report based on this inner join of a query. Can anyone throw some light on this.
Thanks

Hi,
Inner joins don't need to be nested. The results will be the same, no matter in what order the tables are joined.
In Oracle, don't use table names with spaces in them, and don't put spaces before or after the dots that separate table name qualifiers from column names.
I think this is what you want:
INNER JOIN     cubs_snapshot ON     CancelDesc.CancelReason = cubs_snapshot.cancelreason
INNER JOIN     Client            ON     Client.Client           = cubs_snapshot.clientWhenever you have a question, post a little sample data (CREATE TABLE and INSERT statememts) for all tables invlovled, and the results you want from that data.
If you really did need to nest joins, you could join some tables in a sub-query, then use the result set of that sub-query as if it were a table.
For example:
WITH cubs_and_client            AS
     SELECT     CancelReason
     ,     ...     -- Whatever other columns are needed in superior query or queries
     FROM          client
     INNER JOIN     cubs_snapshot     ON     Client.Client           = cubs_snapshot.client
SELECT
INNER JOIN     cubs_and_client     ON     CancelDesc.CancelReason = cubs_and_client.CancelReason
...In this example, the two tables cubs_snapshot and client are joined in a sub-query. The results of that sub-query can be referenced later in the query as if it were a table called cubs_and_client, very much like a view.

Help: Modifying inner join

Hello Folks,
I have an Access Query and am rewriting the whole query in Oracle to run a report.The thing is Am a beginner in oracle and am scratching my head on how to modify this inner join. please help me in rewriting this inner join in oracle. thanks a million
   ((Debtor INNER JOIN MAX_TRANS_DATE AS MAX_TRANS_DATE_1 ON Debtor .
        EVENT_ID = MAX_TRANS_DATE_1.EVENT_ID) INNER JOIN
        TMP$ALL_RECOVERY_TYPE
        ON(Debtor . EVENT_CASE_ID = TMP$ALL_RECOVERY_TYPE . EVENT_CASE_ID) AND
        (Debtor . EVENT_ID = TMP$ALL_RECOVERY_TYPE . EVENT_ID))
INNER JOIN CUBS TRANSACTIONS
    ON (Debtor . EVENT_ID = CUBS TRANSACTIONS . EVENT_ID)
   AND (Debtor . EVENT_CASE_ID = CUBS TRANSACTIONS . EVENT_CASE_ID)

Thanks for getting back. But still am unable to get the correct data. I will try to break it down.
Microsoft Access Table MAX_TRANS_DATE menitoned above in the inner join was originally coming from table called TRANSACTIONS i.e.( MAX_TRANS_DATE = SELECT [Transactions].[EVENT_ID], Max([Transactions].[TRANSDATE]) AS MaxOfTRANSDATE
FROM Debtor INNER JOIN Transactions ON [Debtor].[EVENT_ID]=[Transactions].[EVENT_ID]
GROUP BY [Transactions].[EVENT_ID];
Here the problem is am recreating the access database query in oracle database and we dont have MAX_TRANS_DATE in the Oracle database but we do have TRANSACTIONS table.
So i just used TRANSACTIONS in the inner join instead of MAX_TRANS_DATE.
But the result is wrong.The Field Transdate from TRANSACTIONS is pulling dates as 10/5/2006 instead of 02/01/2010. I suspect something is wrong with the joins.Please help me. I can provide the old access query and the new oracle query that i have created.
Thanks

Can we make apply join a column on which VPD policy applied in Oracle 10g

Hi,
i am planning to apply a column level security using VPD concept into Oracle 10g
but i have a one doubt.
Suppose i am going to apply a VPD policy based on user priviliges on a column DEPTNO in EMP table so whenever a particular user logs in,he will not see the deptno.But he can fetch the data from other table DEPT based on join condition EMP.DEPTNO=DEPT.DEPTNO . Is it possible can we make a join a column on which VPD polciy is applied ?
pls any idea or thought would be appreciable..
Thanks in advance
Anwar

Hi Anwar!
I have not tried yet, but I believe that you can do this.
However imagine the following:
A user U1 has the right to see some values in the deptno column, but not all. This is fine, and I believe that this is what you want to achieve.
A user U2 will see no records from the deptno column. This will impact your query, as your emp.deptno = dept.deptno part of the where clause will deliever no records.
So you have to be careful if this condition could apply and what the impact will be on your software.

Does INNER JOIN work with Oracle 8i ? (ORA-00933)

hi,
I try to execute the sql:
SELECT
A0.FULL_NAME,A0.MANAGER_ID,A0.DEPT_NO,A0.TOP_DEPT
FROM
HR_ORG A0
INNER JOIN
HR_EMP A1
ON
A0.MANAGER_ID=A1.EMP_NO
WHERE
A1.NAME = 'michael'
but I caught an exception:
java.sql.SQLException: ORA-00933: SQL...(message in
chinese)
Does INNER JOIN work with Oracle 8i ?
thanks.

INNER JOIN syntax is introduced in 9i, it does not exists in 8i. You can rewrite your statement:
SELECT
A0.FULL_NAME,A0.MANAGER_ID,A0.DEPT_NO,A0.TOP_DEPT
FROM
HR_ORG A0
, HR_EMP A1
WHERE
A0.MANAGER_ID=A1.EMP_NO
AND
A1.NAME = 'michael'

Outer joins don't return expected results in Oracle 10g

I don't know where to report oracle bugs. So I'm writing here for someone to verify it again and report is a bug to oracle.
--Creating two table and inserting records in each tables
create table table1 ( pk_id number(6) primary key, name_tx varchar2(20) );
create table table1_nls (pk_id number(6) primary key, parent_id number(6), heading varchar2(20), lang_code varchar2(3) );
insert into table1 values( 1, 'test1' );
insert into table1_nls values( 1, 1, 'test heading', 'enu' );
--problem is with the following query.
select * from table1, (select parent_id, heading from table1_nls where lang_code = '' ) table1_nls
where table1.PK_ID = table1_nls.PARENT_ID(+) and pk_id = 1
This returns back one row in Oracle 9i, but none in oracle 10g. If I substitute " lang_code = '' " with lang_code='something' or lang_code is null it works fine. The problem is with comparing the empty value ('').
Logically lang_code is null is the right way of writing the query, but empty ('') works in Oracle 9i,
Is this a valid bug?
If not migration steps should account for this in programs.
drop table table1;
drop table table1_nls;

Hi,
I dont know sql server 2005. But by observing it I feel you are generating sql dynamically based on condition inside the proc.
DECLARE
   TYPE EmpCurTyp IS REF CURSOR;
   emp_cv   EmpCurTyp;
   emp_rec employees%ROWTYPE;
   sql_stmt VARCHAR2(200);
   v_job   VARCHAR2(10) := 'ST_CLERK';
BEGIN
   sql_stmt := 'SELECT * FROM employees WHERE job_id = :j';
   OPEN emp_cv FOR sql_stmt USING v_job;
   LOOP
     FETCH emp_cv INTO emp_rec;
     EXIT WHEN emp_cv%NOTFOUND;
     DBMS_OUTPUT.PUT_LINE('Name: ' || emp_rec.last_name || ' Job Id: ' ||
                           emp_rec.job_id);
   END LOOP;
   CLOSE emp_cv;
END;something like this it will be. it is in oracle documentaion

Performance Problem between Oracle 9i to Oracle 10g using Crystal XI

We have a Crystal XI Report using ODBC Drivers, 14 tables, and one sub report. If we execute the report on an Oracle 9i database the report will complete in about 12 seconds. If we execute the report on an Oracle 10g database the report will complete in about 35 seconds.
Our technical Setup:
Application server: Windows Server 2003, Running Crystal XI SP2 Runtime dlls with Oracle Client 10.01.00.02, .Net Framework 1.1, C# for Crystal Integration, Unmanaged C++ for app server environment calling into C# through a dynamically loaded mixed-mode C++ DLL.
Database server is Oracle 10g
What we have concluded:
Reducing the number of tables to 1 will reduce the execution time of the report from 180s to 13s. With 1 table and the sub report we would get 30 seconds
We have done some database tracing and see that Crystal Reports Issues the following query when verifying the database and it takes longer in 10g vs 9i.
We have done some profiling in the application code. When we retarget the first table to the target database, it takes 20-30 times longer in 10g than in 9i. Retargeting the other tables takes about twice as long. The export to a PDF file takes about 4-5 times as long in 10g as in 9i.
Oracle 10g no longer supports the /*+ RULE */ hint.
Verify DB Query:

Does anyone have any suggestions on how we can improve the report performance with 10g?

Hi Eric,
Thanks for your response. The optimizer mode in our 9i database is CHOOSE. We changed the optimizer mode from ALL_ROWS to CHOOSE in 10g but it didn't make a difference.
While researching Metalink I came across a couple of documents that indicated performance problems and issues with using certain data-dictionary views in 10g. Apparently, the definition of ALL_OBJECTS, ALL_ARGUMENTS and ALL_SYNONYMS have changed in 10g, resulting in degradation in performance, if quieried against these views. These are the same queries that crystal reports is queriying. We'll try the workaround suggested in these documents and see if it resolves the issue.
Here are the Doc Ids, if you are interested:
Note 377037.1
Note:364822.1
Thanks again for your response.

Issue on left outer join query in 10G

Dear Mr./Mrs./Ms. Oracle expertise,
The following query structure can function properly in Oracle 9i, but not work in Oracle 10G.
Please kindly advise what happened in Oracle 10G?
Is it a bug in 10G? If yes, any patch for it?
select a.col1,
a.col2,
a.col5,
b.col3,
b.col4
from t1 a
inner join t2 c on c.col1 = a.col1
left join (select col3
col4
from t3) b
on b.col1 = a.col1
and a.col2 = 'Y' <---------- seems 10G cannot allow this condition
where a.col5 = 123;
Purpose of above SQL
====================
Only those records from t1 table with a.col2 = 'Y' will
do the left outer join to "b" table and get the columns b.col3 and b.col4
Result set in Oracle 9i
=======================

Dear Schneider,
Sorry that there was a typo in my query.
Below is the revised query.
select a.col1,

Update statement with inner join

Hello everyone. I am am trying to do an update statement with an inner join. I have found several examples of SQL statements that work with Sql server and mysql but they don't work in Oracle. Does anyone know the proper way in Oracle 10G? I am trying to update all fields in one table from fields in another table.
for example:
UPDATE table3
SET
TL3.name = TL2.name,
TL3.status = TL2.status,
TL3.date = TL2.date
FROM table3 TL3 JOIN table2 TL2
ON (TL3.unique_id = TL2.unique_id);
any help will be appreciated.

Hi,
You can also use MERGE, like this:
MERGE INTO table3     dst
USING   (
         SELECT unique_id
         ,         name
         ,         status
         ,         dt          -- DATE is not a good column name
         FROM    table2
     )          src
ON     (dst.unique_id     = src.unique_id)
WHEN MATCHED THEN UPDATE
SET     dst.name     = src.name
,     dst.status     = src.status
,     dst.dt          = src.dt
;Unlike UPDATE, this lets you avoid essentially doing the same sub-query twice: once in the SET clause and then again in the WHERE clause.
Like UPDATE, you don't acutally join the table being changed (table3 in this case) to the other table(s); that is, the FROM clause of the suib-query does not include table3.
Riedelme is right; you'll get better response to SQL questions like this in the SQL and PL/SQL forum:

Need Advise and Suggestions-Oracle 10g

Hi,
I have been working on databases as DB developer(mainly PLsql)--Oracle 10g
Recently,i have joined in a particular position where I have been asked to find out areas where
improvement is necessary / or areas where improvement or changes would help very much and also gradually implement all best practises avaialable.
So,could you please help me with these queries
(1)What are the most important areas that i can start with the database which would impact largely the entire database.How can i start with it? any steps or process
(2)I had once taken a report out for the expensive SQLs running.But that dint help much...because those SQLs were used temporarily on and off.
Similarly,what are the other points to be looked on.
(3)Things which can be replaced with the industry standarad better ones fully.
an example would be...like.."following a particular naming format,or coding style,etc
Thanks
Rohit

Hi Rohit,
This is a pretty huge subject. To start, I'd say you need to talk to the business. Talk to the users of the database, cause they are your customers. Get a clear understanding of the most critical business processes. Start with the most critical ones, and get performance profiles. How long do they take to run? What's the customer's perception of the process performance? If it's acceptable, move on to the next one. If it's not acceptable, you'll need to dig deeper. Look at each piece of the process. Where is the most time being spent? Can it be improved? This step will be a combination of process improvement and setting the correct expectation. Often, the user doesn't really know what is realistic in terms of performance. If you have a 2 billion row table that needs to get full table scanned, expecting a response time of a few seconds just simply isn't going to happen. You need to clearly convey that to the customer. On the other hand, at the same time, you should be on the lookout for real improvements. If you can re-write the SQL or add an index, and eliminate the FTS on that 2 billion row table, maybe a response time of a few seconds is actually realistic.
It's all about understanding the system, and understanding the customer's needs, and how they intersect. It will be an iterative process, and will take some time.
As to "best practices", I'm not a fan of them. Understand your system, understand your customer's needs, and understand how Oracle actually works. If you can master that, you'll be unstoppable. Note that many, many people, much smarter people than me, have spent a lifetime trying to master those three points... :-)
Good luck with your new job!
