Join Query hanging

hi experts,
please help on this, we have migrated database from 10g to 11.2.0.3 , Everything went sccessful but one of the simple join query hanging occasionally in new upgraded database. is there any known issue or anything need to add after migration for sqls?,also before migration its was executed without any issues. that query is joining and fetching from two more tables . is there any generic reason please provide that would be helpful to analyze, Thanks in Advance.

why wasn't this discovered during testing prior to the upgrade?
does new DB have current statistics?
How do I ask a question on the forums?

Query Hangs while Parsing

In one of our databases, one of the Select query hangs at the parsing stage. The query was working fine few days back. How and what can be traced to see the cause of this hang. Database is in 10.2.0.3 and statistics has been gathered for all the affected tables.

Thanks for the info. The SEQ# is not changing in the v$session_waits. I have found a workaround for this problem. If I delete the statistics for CS_MEASUREMENT table, the query gets executed in .35 secs! If i collect stats again and runs, it hangs.
The session trace below.

Hi,
I wrote a general ABAP program which can be configured to grab contrent from an URL and post that content as a new PI message into the integration adapter .... from that point on normal PI configuration can be used to route it to anywhere ...
It can be easily scheduled as a background job to grab content on a daily basis etc ...

Deciphering column names in a join query using jdbc

hi all....
I am making a database adapter for a generic report generater. This adapter would be forming queries involing various tables. There are two ways of doing it . I fire an sql on parent table to get the keys and then go to child table for each one of them or i form a join query to get desired result.
i want to go with the later approach where my query would be forming a join. The problem comes when table involved in this join has columns with the same name. for eg if a column "NOTE" is there in table A as well as table B on which i have a join. Resultset returns me with two "NOTE" columns and i cannot recognize which one belongs to which table.
all API calls including getString("Note") seems to be referring to the first occurence of "Note" column.
Also getTableName() and getSchemaName() APIs on resultsetMetadata doesnt return in anything in case of joins.
Any pointers would be most appreciated.
cheers
vivek

thanks for suggesting this solution ... though i had thought of the same onece .... unfortunately i cannot implement something like this coz out of the result set i have to instantiate an object hierarchy depending on the schema ....
this also puts me in a doubt whether i can use join in my case.
for eg ... .
lets say we have a customer talbe and and address table which has one to many relationship .... one contact can have multiple addresses.
Assuming a contanct "Joe Bloggs" having 3 addresses ...a query like following
select contact.firstname contactfirstname , address.streetname addressstreetname from contact , address where contact.contactid = address.contactid
this would return me 3 rows and i can also recognize various columns with their aliases ..
but i would lose an important fact that i have to create one java object for contact class and 3 instances for addresses which i have to return finally.
this means that i would like to return an object hierarchy with one contact object and 3 address object underneath it linked with contactid.
Any other suggestions after reading the complete requirement are most welcome ...sorry for not puting the entire thing at first.
i guess the only soln left is to visit contact and address table separately. :(

How can I perform this kind of range join query using DPL?

How can I perform this kind of range join query using DPL?
SELECT * from t where 1<=t.a<=2 and 3<=t.b<=5
In this pdf : http://www.oracle.com/technology/products/berkeley-db/pdf/performing%20queries%20in%20oracle%20berkeley%20db%20java%20edition.pdf,
It shows how to perform "Two equality-conditions query on a single primary database" just like SELECT * FROM tab WHERE col1 = A AND col2 = B using entity join class, but it does not give a solution about the range join query.

I'm sorry, I think I've misled you. I suggested that you perform two queries and then take the intersection of the results. You could do this, but the solution to your query is much simpler. I'll correct my previous message.
Your query is very simple to implement. You should perform the first part of query to get a cursor on the index for 'a' for the "1<=t.a<=2" part. Then simply iterate over that cursor, and process the entities where the "3<=t.b<=5" expression is true. You don't need a second index (on 'b') or another cursor.
This is called "filtering" because you're iterating through entities that you obtain from one index, and selecting some entities for processing and discarding others. The white paper you mentioned has an example of filtering in combination with the use of an index.
An alternative is to reverse the procedure above: use the index for 'b' to get a cursor for the "3<=t.b<=5" part of the query, then iterate and filter the results based on the "1<=t.a<=2" expression.
If you're concerned about efficiency, you can choose the index (i.e., choose which of these two alternatives to implement) based on which part of the query you believe will return the smallest number of results. The less entities read, the faster the query.
Contrary to what I said earlier, taking the intersection of two queries that are ANDed doesn't make sense -- filtering is the better solution. However, taking the union of two queries does make sense, when the queries are ORed. Sorry for the confusion.

Help with Inner Join query in SQL

Hope someone can help with this, as this is quite an involved project for me, and I'm just about there with it.
My table structure is :
table_packages
packageID
package
packageDetails
etc
table_destinations
destinationID
destination
destinationDetails
etc
table_packagedestinations
packageID
destinationID
..so nothing that complicated.
So the idea is that I can have a package details page which shows the details of the package, along any destinations linked to that package via the packagedestinations table.
So this is the last part really - to get the page to display the destinations, but I'm missing something along the way....
This is the PHP from the header, including my INNER JOIN query....
PHP Code:
<?php
$ParampackageID_WADApackages = "-1";
if (isset($_GET['packageID'])) {
$ParampackageID_WADApackages = (get_magic_quotes_gpc()) ? $_GET['packageID'] : addslashes($_GET['packageID']);
$ParamSessionpackageID_WADApackages = "-1";
if (isset($_SESSION['WADA_Insert_packages'])) {
$ParamSessionpackageID_WADApackages = (get_magic_quotes_gpc()) ? $_SESSION['WADA_Insert_packages'] : addslashes($_SESSION['WADA_Insert_packages']);
$ParampackageID2_WADApackages = "-1";
if (isset($_GET['packageID'])) {
$ParampackageID2_WADApackages = (get_magic_quotes_gpc()) ? $_GET['packageID'] : addslashes($_GET['packageID']);
mysql_select_db($database_connPackages, $connPackages);
$query_WADApackages = sprintf("SELECT packageID, package, costperpax, duration, baselocation, category, dateadded, agerange, hotel, educational_tours, field_trips, corporate_outings, plant_visits, budget_package, rollingtours, teambuilding, description, offer FROM packages WHERE packageID = %s OR ( -1= %s AND packageID= %s)", GetSQLValueString($ParampackageID_WADApackages, "int"),GetSQLValueString($ParampackageID2_WADApackages, "int"),GetSQLValueString($ParamSessionpackageID_WADApackages, "int"));
$WADApackages = mysql_query($query_WADApackages, $connPackages) or die(mysql_error());
$row_WADApackages = mysql_fetch_assoc($WADApackages);
$totalRows_WADApackages = mysql_num_rows($WADApackages);
$colname_educationalDestinations = "1";
if (isset($_GET['PackageID'])) {
$colname_educationalDestinations = (get_magic_quotes_gpc()) ? packageID : addslashes(packageID);
mysql_select_db($database_connPackages, $connPackages);
$query_educationalDestinations = sprintf("SELECT * FROM destinations INNER JOIN (packages INNER JOIN packagedestinations ON packages.packageID = packagedestinations.packageID) ON destinations.destinationID = packagedestinations.destinationID WHERE packages.packageID = %s ORDER BY destination ASC", GetSQLValueString($colname_educationalDestinations, "int"));
$educationalDestinations = mysql_query($query_educationalDestinations, $connPackages) or die(mysql_error());
$row_educationalDestinations = mysql_fetch_assoc($educationalDestinations);
$totalRows_educationalDestinations = mysql_num_rows($educationalDestinations);
?>
And where I'm trying to display the destinations themselves, I have :
<table>
        <tr>
                 <td>Destinations :</td>
            </tr>
           <?php do { ?>
        <tr>
             <td><?php echo $row_educationalDestinations['destination']; ?></td>
        </tr>
        <?php } while ($row_educationalDestinations = mysql_fetch_assoc($educationalDestinations)); ?>
</table>
If anyone could have a quick look and help me out that would be much appreciated - not sure if its my SQL at the top, or the PHP in the page, but either way it would be good to get it working.
Thanks.

First off, you need to get the database tables so that there is a relationship between them.
In fact, if there is a one to one relationship, then it may be better to store all of your information in one table such as
table_packages
packageID
package
packageDetails
destination
destinationDetails
etc
If there is a one to many relationship, then the following would be true
packages
packageID
package
packageDetails
etc
destinations
destinationID
packageID
destination
destinationDetails
etc
The above assumes that there are many destinations to one package with the relationship coloured orange.
Once you have the above correct you can apply your query as follows
SELECT *
FROM packages
INNER JOIN destinations
ON packages.packageID = destinations.packageID
WHERE packages.packageID = %s
ORDER BY destination ASC
The above query will show all packages with relevant destinations

Problem getting results with no unique key in a joined query

I created a descriptor to do a joined query, which generated a query in log as:
Select t0.empID,t1.empID, t1.phone from Emp t0, Phone t1
where t0.empId=t1.empId and t0.empId=1001
When I run it, I got the result as:
1001,1001,9999999
1001,1001,9999999
The correct result should be (I copy and paste the query from log into SQL-Plus):
1001,1001,9999999
1001,1001,1234455
I suspect this is caused by Toplink caching objects by primary key. I wonder if anybody has a solution for this.
My descriptor is created using WorkBench. Emp is the primary table, Phone as additional table linked by foreignKey empId.
The join is implemented by modifying the descriptor as the following:
ExpressionBuilder builder = new ExpressionBuilder();
descriptor.getQueryManage()
.setMultipleTableJoinExpression(
builder.getField("EMP.EMPID").equal(
builder.getField("EMP.EMPID")));
descriptor.disableCacheHits();
I'd really appreciate your help.

I am implementing a people search function. The batch reading is quite expensive if toplink does a read query for every person. A customized query requires only one database access, the other way may requires hundreds.
I don't want to use the cache either in this case because the database is also accessed by legacy system which cann't notify toplink any updates.
I opened a TAR on this and the solution I got is to use ReportQuery rathen than ReadAllQuery. The only problem here is that now I have to map the query result to my class manually.

How to build table join query in Jdeveloper

Hi,
Can someone tell me how to build table join query in Jdeveloper's Expression Builder UI?

[Is it possible to create a table of contents in Crystal Reports?|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_erq/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333233313335333133303330%7D.do]

Filter on "---" in Left Outer Join Query

Hi guys,
very basic question but I have not found an answer, yet. I built an left outer join MDO query and need to select all those dataset that did not find a "partner", that is fields are set to "---". However, I do not manage to filter on '---', NULL...
When using SQL, it appears to be a String "---" but in MDO???

Hey guys, found out that IS NULL needs to be used in query. Anyway, it appears to cause problems somewhere else.
I placed an IS NULL filter expression inside a join query but query did not return any results when called in by transaction. After removing this line, both NULL and NOT NULL data were returned. When used in test mode, IS NULL was working fine...

Left outer join query

Hi Experts,
    I am facing a problem with left outer join query. Am using one standard table and ztable for this join. My problem is values are not extracted from the Ztable.
Query:
      SELECT b~lifnr b~belnr b~gjahr b~xblnr b~shkzg b~blart b~zfbdt b~budat b~wrbtr
         b~wskto b~zlspr s~EXTRACT_STATUS s~maturity_date FROM bsik AS b
         LEFT OUTER JOIN zprm_rvne_sapdoc AS s
         ON s~belnr EQ b~belnr
         AND s~gjahr EQ b~gjahr
         INTO CORRESPONDING FIELDS OF TABLE it_join
            WHERE b~zlsch = p_zlsch
            AND b~xblnr IN so_invno
            ORDER BY b~lifnr b~xblnr.
I have all entries of BSIK table in Ztable with extract status as Y but this query is not fetching extract status and maturity date of ztable so it is blank in the internal table.
Need solution.

Hi,
see the sample wiki for writing the Left outer join
http://wiki.sdn.sap.com/wiki/display/Snippets/EmployeeInfotype0000to9999ChangeHistory
Specifying Two or More Database Tables as a Left Outer Join
The left outer join, on the other hand, reads lines from the left-hand database table or join even if there is no corresponding line in the right-hand table.
SELECT...
FROM <tab> LEFT [OUTER] JOIN <dbtab> [AS <alias>] ON <cond>
       <options>
<tab> and <dbtab> are subject to the same rules and conditions as in an inner join. The OUTER addition is optional. The tables are linked in the same way as the inner join with the one exception that all lines selected from <tab> are included in the final selection. If <dbtab> does not contain any lines that meet the condition <cond>, the system includes a single line in the selection whose columns from <dbtab> are filled with null values.
In the left outer join, more restrictions apply to the condition <cond> than in the inner join. In addition to the above restrictions:
EQ or = is the only permitted relational operator.
There must be at least one comparison between columns from <tab> and <dbtab>.
The WHERE clause may not contain any comparisons with columns from <dbtab>. All comparisons using columns from <dbtab> must appear in the condition <cond>.
If we have two tables named stud1,stud2 with the following data
Stud1: id Name stud2: id Name
1 xxx 1 aaa
2 yyy 2 bbb
3 zzz 4 ccc
4 www 6 ddd
When we use Left Outer Join we get the output as:
1 aaa
2 bbb
3 <Null>
4 ccc
When we use Right Outer Join we get the output as:
1 aaa
2 bbb
4 ccc
<Null> ddd
When we use Full Outer Join we get the output as:
1 aaa
2 bbb
3 <Null>
4 ccc
<Null> ddd

I wanted to modify the query, since its taking lot of time to load the data.
Please suggest : -
Treat this is very urgent.

Hi Shyamal,
In your program , you are using "into corresponding fields of ".
Try not to use this addition in your select query.
Instead, just use "into table it_list".
As an example,
Just give a normal query using "into corresponding fields of" in a program. Now go to se30 ( Runtime analysis), and give the program name and execute it .
Now if you click on Analyze button , you can see, the analysis given for the query.The one given in "Red" line informs you that you need to find for alternate methods.
On the other hand, if you are using "into table itab", it will give you an entirely different analysis.
So try not to give "into corresponding fields" in your query.

SP.

Oracle 9.2.0.6; query hangs if partition doesn't exist

Hallo all,
this is the first time I post on this forum.
I work in a group of PL\SQL developers in Italy. Few day ago we had a problem with a query and like to find out what the problem is.
We have an Oracle DB version 9.2.0.6 (old I know) in a production environment. Linux OS.
The query was made to extract data from a partitined table, on a partioned field, in our casa one Year. By mistake we have serced for the wrong year, 2013. There where no data for that year and therefor no partition.
So, happened that the query hangs and after 24 hours was terminated.
What we expected indeed was a zero records retirned in, at the most, few minutes, see that the table, in severa partition contains about 16 million records.
The we tested the same query but in a different enviroment, Oracle 11gr2, same table structure, same partitioning, without partition 2013, and the query completed in less tha 1 minute with zero records in output.
At this point we thought of a bug, but can't find any reference.
Has anyone had a similar experience or can give some indication of possible bug report.
Thanks for any help.

Hi Rob,
thank you for your answer.
Sorry if this is not the best forum. I am not very practical.
I try to answer to your questions.
At a first time we thought the query did a full scan on the table. Yes. But even to full scan 16.000.000 records split in no more than 8 partition (at this time) shouldn't take up to 24 hours and never stop running. I think.
We don't have a DBA role so we do not have full control over what is running. And take too long time to open a ticket and ask the DBA to check.
What we did is testing the same query in a pre-prod environment, which is an Oracle 11gr2.
I understand that it is not very usual to have a pre-production environment with a latest version of oracle but this is the way we have to work.
Anyway, the test in pre-production worked very well. Without 2013 partition the return was very fast and we had zero records as expected.
Then we found a workaround for production, ora 9. Call it work around maybe is too much ........
We created the 2013 partition and run the query. The respons was then succesfull in about the same time than in pre-prod. Less than one minute and zero records.
And this is fine for us.
What we don't understand is why this different behavior with two different version of DB. Thats why we think it is due to a bug. We only want to find out whether it is this or if there is a different reason.
Some other response or help would help.
Thank you.

Cartesian Join query optimization

Hello Experts!
I have a question about cartesian join query which might look a bit weird.
Assume the SQL query like that:
SELECT DISTINCT A.NAME
FROM A, B, C;
Here we have cartesian join for 3 tables A, B and C.
It looks to me, in order to get the result for such a particular SQL tables/sets B and C need to be accessed only to ensure they return at least 1 row (otherwise result set is empty), query table A, but there is no actual need to join the data.
If you run such a query Oracle is doing full table scans and actually joins the data.
Yes, DBMS is doing exactly what you are asking for, but I wonder if there is any way (SQL hint or db parameter or anything else) to enforce more optimal access path here?
Obvious solution to remove B and C tables from the SELECT statement is not acceptable. :-)
Thank you!

Your statement in the other thread indicates you don't understand how the BI prompts actually work because you say you want it to do something that doesn't make sense for it to do.
Of course Product and Account levels will be constrained to the interval you specified. It wouldn't make sense for them not to be. Because that would mean returning data for based on product and account levels that has a different open data range than what you specified.
All UI prompt dialogs I have seen use AND relationships between the parameters. If there are three parameters (A, B, C) then the ultimate relationship is 'A AND B AND C'; not 'A OR (B AND C)', 'A AND (B OR C)', 'A OR (B OR C).
Unless the tool allows you to select OR relationships you need to use a separate dialog box (parameter dialog) for each condition set.:-)
I understand how BI prompts work and basically agree on your comment, but there are two problems here:
1. I need to convince the customer his original requirements are not valid. Customer want it to work different way and there are some reasons why.
2. There are pretty large dimensions and fact tables used here, so when I choose filter criteria for the Product (which is small table) to populate/recalculate prompt values, large SR dimension and fact tables are joined too, and if there are Account dimension filters added, huge Account dimension will be added as well. This looks to be a bit sub-optimal for just populating the Product prompt values.
Of course, technically this is solvable, but requires to put some extra effort and does not solve the 1st issue.
That other link doesn't explain the sample code you posted in this thread. Post the actual query that is being generated and the query that you want to actually use.This is what is generated:
>

This is what is actually needed to query this data:

Sql query hangs close to the end

Hi:
I am on 10.2.0.3.
My rather simple query hangs for a few minutes close to the end. It's supposed to return 288 rows and it immediately returns 285, then hangs for 4-5 min, than returns the remaining 3 rows. Kind of similar behavior to using "First_rows" hint - which I'm not using...
The table has about 100,000 rows.
Some relevant info is below.
Any ides appreciated.
TIA

You said the query is supposed to return 288 rows, but from the explain plan, Oracle "see" only 1 row to be returned. Are the stats up-to-date ? What's the actual query ?
Please, on the forum side, use tags before and after your code to keep it readable (preserve blanks and tabs).
