Java - SetDatasource - JOIN query

Hi,
I have created a rpt file using crystal report plugin for eclipse.
This report uses 3 Tables. Works fine. but when i want to push a java sql resultset as the datasource the result isn't good, only get one row.
( I need to push resultset because i need to dinamically manage the where clause of my query. the where clause might be linked to each of the three tables)
Here's my jsp code.
<%@ page import="javax.sql.*"%>

Statement stmt = connection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
ResultSet res = stmt.executeQuery(query);

ReportClientDocument reportClientDocument = new ReportClientDocument();
reportClientDocument.setReportAppServer(ReportClientDocument.inprocConnectionString);
/* Ouverture du rapport */
reportClientDocument.open("/report/TEST.rpt", 0);
Tables tables=reportClientDocument.getDatabaseController().getDatabase().getTables();
reportClientDocument.getDatabaseController().setDataSource(res, tables.getTable(2).getAlias() , tables.getTable(2).getAlias());
reportClientDocument.getDatabaseController().setDataSource(res, tables.getTable(1).getAlias() , tables.getTable(1).getAlias());
reportClientDocument.getDatabaseController().setDataSource(res, tables.getTable(0).getAlias() , tables.getTable(0).getAlias());

int bytesRead;
byte[] byteArray = new byte[1024];
while((bytesRead = byteArrayInputStream.read(byteArray)) != -1)
response.getOutputStream().write(byteArray, 0, bytesRead);
response.getOutputStream().flush();
response.getOutputStream().close();
/* Fermeture du ReportClientDocument */
reportClientDocument.close();
%>
The point might be here
Tables tables=reportClientDocument.getDatabaseController().getDatabase().getTables();
reportClientDocument.getDatabaseController().setDataSource(res, tables.getTable(2).getAlias() , tables.getTable(2).getAlias());
reportClientDocument.getDatabaseController().setDataSource(res, tables.getTable(1).getAlias() , tables.getTable(1).getAlias());
reportClientDocument.getDatabaseController().setDataSource(res, tables.getTable(0).getAlias() , tables.getTable(0).getAlias());
if i only use
Tables tables=reportClientDocument.getDatabaseController().getDatabase().getTables();
reportClientDocument.getDatabaseController().setDataSource(res, tables.getTable(2).getAlias() , tables.getTable(2).getAlias());
i get an connection error message
same thing with any other combination like this
Tables tables=reportClientDocument.getDatabaseController().getDatabase().getTables();
reportClientDocument.getDatabaseController().setDataSource(res, tables.getTable(0).getAlias() , tables.getTable(0).getAlias());
reportClientDocument.getDatabaseController().setDataSource(res, tables.getTable(1).getAlias() , tables.getTable(1).getAlias());
reportClientDocument.getDatabaseController().setDataSource(res, tables.getTable(2).getAlias() , tables.getTable(2).getAlias());
do someone have any explanation?

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.

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

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.
Regards,
SP.

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:
>
select distinct T311691.X_CUST_SUBTYPE as c1
from
WC_LOV_SR_AREA_H T311695,
WC_LOV_PROD_H T311687,
WC_LOV_CUST_TYPE_H T311691,
W_SRVREQ_D T302384 /* Dim_W_SRVREQ_D */
where ( T311687.LEV1 = 'Product X' and T311691.X_CUST_TYPE = 'Business' and T302384.OPEN_DT between TO_DATE('2012-03-01 00:00:00' , 'YYYY-MM-DD HH24:MI:SS') and TO_DATE('2012-03-31 00:00:00' , 'YYYY-MM-DD HH24:MI:SS') )
order by c1

This is what is actually needed to query this data:

Adding a field to rhe join query

Dear Friends,
I need your help in adding a field to a join query.
I have created a reort using join(SQVI). Now i want to add an addition field to that report. The issue is the field i am looking at is stored in structure. Is there any way i can add this field....
Sanjay

It is not possible here (in SQVI).
you have to Go with Query.
SQ02 using this Create infoset, add all the tables , here include that structure field, and then add the logic to populate the field.
Now go to SQ01 and create Query.

Inner join query used with 7 Database tables

HI All,
In a report they used the Inner join Query with 6 Data base table..now there is a performance issue with at query.
its taking so much of time to trigger that query. Please help how to avoid that performance issue for that.
In that 2 database tables containing lakhs of records..
According to my knowledge it can be avoided by using secondary indexs for those 2 database tables..
and by replacing the Inner join Query with FOR ALL ENTRIES statement.
i want how to use the logic by using FORALL ENTRIES statement for this..
So, please give you proper suggestion to avoid this issue..
Thanking you.

Hi,
And what do you mean with "they used"? If "SAP used" then yo will need to ask a SAP for note
FOR ALL ENTRIES is quite good described in help. Please search forum also.
Without query it won't be possible to tell how it can be optimized, however you can try to use SE30/SAT and ST05. Maybe it will help you.

MV Incremental Refresh on join query of remote database tables

Hi,
I am trying to create a MV with incremental refresh option on a join query with 2 tables of remote database.
Created MV logs on 2 tables in the remote database.
DROP MATERIALIZED VIEW LOG ON emp;
CREATE MATERIALIZED VIEW LOG ON emp WITH ROWID;
DROP MATERIALIZED VIEW LOG ON dept;
CREATE MATERIALIZED VIEW LOG ON dept WITH ROWID;
Now, trying to create the MV,
CREATE MATERIALIZED VIEW mv_emp_dept
BUILD IMMEDIATE
REFRESH FAST
START WITH SYSDATE
NEXT SYSDATE1/(24*15)+
WITH PRIMARY KEY
AS
SELECT e.ename, e.job, d.dname FROM emp@remote_db e,dept@remote_db d
WHERE e.deptno=d.deptno
AND e.sal>800;
Getting ORA-12052 error.
Can you please help me.
Thanks,
Anjan

Primary Key is on EMPNO for EMP table and DEPTNO for DEPT table.
Actually, I have been asked to do an feasibility test whether incremental refresh can be performed on MV with join query of 2 remote database tables.
I've tried with all combinations of ROWID and PRIMARY KEY, but getting different errors. From different links, I found that it's possible, but cannot create any successful testcase anyway.
It will be very much helpful if you can correct my example or tell me the restrictions in this case.
Thanks,
Anjan
