JDBC outbound reading from multiple tables
Hi,
I have a scenario in which I have to read data from multiple tables.
The keys of these tables (employee details) are dependent on a employee master table.
Now there is a 1-N relationship between master and the details table. I have to send the data to an IDOC.
I am stuck since reading from all the tables at the same time is not possible.
Please suggest some solution.
Thanks,
Vaibhav
Hi Bhavesh,
Thanks for ur reply. It solved my problem.
Full points to you...
Pls help me with one more issue.
As per the method u told i am reading from multiple tables. Each table has data for multiple employees.
The response message is of the format
<STATEMENT_Table1_response>
<row>
Data for emp 1
</row>
<row>
Data for emp 1
</row>
</STATEMENT_Table1_response>
<STATEMENT_Table1_response>
<row>
Data for emp 2
</row>
<row>
Data for emp 2
</row>
</STATEMENT_Table1_response>
<STATEMENT_Table2_response>
<row>
Data for emp 1
</row>
<row>
Data for emp 1
</row>
</STATEMENT_Table2_response>
<STATEMENT_Table2_response>
<row>
Data for emp 2
</row>
<row>
Data for emp 2
</row>
</STATEMENT_Table2_response>
I want to collect it to an idoc where i have data of each employee collected together. Like
<Emp1>
<Data from Table1>
<Data from Table2>
</Emp1>
<Emp2>
<Data from Table1>
<Data from Table2>
</Emp2>
I have tried many ways and looks like a custom code in java have to written.
Is there anything else possible?
Thanks in Advance,
Vaibhav

Jdbc getting data from multiple tables
hi guys
how can i get data from multiple tables in MSAccess
please help>
here is code thata i want to do
i have 3 tables in my MSAccess databace
Stud_O which consist name,surname fields
Stud_I consist address,tel
Stud_E department,faculty fields
Based on this I would guess that you are missing a key field. There is no way to connect the tables.
I make the class to insert data to the tables. But
cant do getting datas from this tables.
can anybody help me in making query
and method that displays reultset strings to the

A select ...
select name,surname from Stud_O. Use the executeQuery() method. -
JDBC-XI-FILE scenario. How to extract data from multiple tables
Hi,
At this moment I didn't have the access for XI system. So here I have some silly question. Could you please clarify the same ??
If I got to extract data from single table using JDBC adapter I can put the below query in communication channel
SELECT *FROM orders WHERE new='true'.
But if I got to extract data from multiple tables, logic to be used should be like as shown below. ( from previous thread------prabhu).
SELECT <Table_2>.EID, <Table_2>.FName, <Table_2>.LName, <Table_1>.REC_DAT, <Table_1>.DESCRP
FROM <Table_1> INNER JOIN <Table_2> on
<Table_1>.CARDNO = <Table_2>.CARD
where REC_DAT = <condition>
union
SELECT <Table_2>.EID, <Table_2>.FName, <Table_2>.LName, <Table_1>.REC_DAT, <Table_1>.DESCRP
FROM <Table_1> INNER JOIN <Table_2> on
<Table_1>.CARDNO = <Table_2>.CARD
where REC_DAT = <condition>
But my query is ........how to put the above entire code in one line. (i.e in Qery place of communication channel ) ??
Thanks
KumarHi Palnati,
You either use a select query with join or a stored procedure which will contain the logic to extract the data from multiple tables. But, the limitation in case of stored procedure is u can hv only one selct query in it.
You write ur actual query provided in the parameter 'Query SQL Statement". u can also wrt a stored procedure in it. Also, u can provide a update statement in it which will update a certain flag so tht u don selct the data again.
Check the following link

Sender JDBC Adapter : Fetch records from multiple tables
Hi Friends,
I am using sender JDBC adapter to select few records from DB2 database table.
This scenario is working fine.
Now my requirement is to fetch records from 3 tables. These table are independent to each other. There is no primary key or foreign key.
Please let me know how to write the sql in sender JDBC adapter to fetch records from these 3 tables.
Thanks,
Sandeep Mauryahi sandeep...
if the tables are completely independent and do not share any primary / foreign key relation ship...
why dont u think towards creating a seperate interface for each of them..
or if u still want to select from multiple table at once..the best way would be to write a stored procedure on the sender side which do all the fetching n processing and pass the final resultset to PI
or u can think towards fetching the data from 1 table and then in UDF do lookup from other tables..which again is tricky and performace intensive -
** Is it possible to give select command from multiple tables in JDBC
Hi Friends,
Is it possible to give the select command to select data from multiple tables directly in the 'Query SQL statement' in JDBC sender communication channel ? (Instead of Stored Procedure)
Thanking you.

Generic datasource by function module to fetch data from multiple tables?
I'm writing a function module to fetch price, for generic datasource.
At first, extract test is OK. But InfoPackage never stop when loading data to PSA in BW.
And I find the example codes:
OPEN CURSOR WITH HOLD S_CURSOR FOR
SELECT (S_S_IF-T_FIELDS) FROM SFLIGHT
WHERE CARRID IN L_R_CARRID AND
CONNID IN L_R_CONNID.
ENDIF. "First data package ?
* Fetch records into interface table.
* named E_T_'Name of extract structure'.
FETCH NEXT CURSOR S_CURSOR
APPENDING CORRESPONDING FIELDS
OF TABLE E_T_DATA
PACKAGE SIZE S_S_IF-MAXSIZE.
IF SY-SUBRC <> 0.
CLOSE CURSOR S_CURSOR.
RAISE NO_MORE_DATA.
ENDIF.
S_COUNTER_DATAPAKID = S_COUNTER_DATAPAKID + 1.
ENDIF.
There using Cursor to fetch data package by package, and raise exception NO_MORE_DATA to stop the loading process.
Now I fetch data from multiple tables, I don't think I can use Cursor.
Then How can I handle this?
Thanks a lot.Thanks

Delete records from multiple table
Hi,
I need to delete records from multiple tables using a single delete statement. Is it possible ? If so please let me know the procedure.
Kindly Help.
Thanks,
Alexander.Hi Tim,
Syntax of DELETE statement does not allow for multiple tables to be specified in this way. Infact, none of the DMLs allow you to specify table names like this.
Technically, there are other ways of deleting from multiple tables with one statement.
1. "Use a trigger":
What was probably meant by this is that you have a driving-table on which you create a on-delete trigger. In this trigger, you write the logic for deleting from other tables that you want to delete from.
This does mean a one-time effort of writing the trigger. But the actual DML operation of deleting from all the tables would be simply triggered by a delete on driving-table.
2. Dynamic SQL:
Write a PL/SQL code to open a cursor with table-names from which you want the data to be deleted from. In the cursor-for loop, write a dynamic SQL using the table-name to delete from that table.
3. Using Foreign-Key constraint with Cascade-Delete:
This I feel is a more 'cleaner' way of doing this.
Having to delete data from multiple tables means that there is some kind of parent-child relationship between your tables. These relationships can be implemented in database using foreign-key constraints. While creating foreign-key constraint give the 'on delete cascade' clause to ensure that whenever data is deleted from parent-table, its dependent data is deleted from child-table.
Using foreign-key constraint you can create a heirarchy of parent-child relationships and still your DELETE would be simple as you would only have to delete from parent-table.
IMPORTANT: Implementing foreign-key constraints would also impact other DML operations that you should keep in mind. -
Hi,
I have a method that has to access records from multiple tables and store them all in a file. It's something like this:
switch (tableId){
case 'A' : query="SELECT * FROM TABLE_A
WHERE ID = '" + tempId + "'";
ResultSet rs = stmt.executeQuery (query);
rs.close();
break;
case 'B' : query="SELECT * FROM TABLE_B
WHERE ID = '" + tempId + "'";
rs = stmt.executeQuery (query);
rs.close();
break;
case 'C' : query="SELECT * FROM TABLE_C
WHERE ID = '" + tempId + "'";
rs = stmt.executeQuery (query);
rs.close();
break;
My problem is that I get an "Invalid cursor" error the second time I enter the loop. I've been reading up on cursors but I still don't know what to do. Can I use ResultSet to return multiple rows from multiple tables? If not, what can I use? Please help!
Thanks in advance.remove the "rs.close()" from the switch statement. use "rs.close()" after your loop ends.

Dbms_xmlgen.newcontext query from multiple tables and ||
I have two questions
How do I get a dbms_xmlgen.context to query from multiple tables? I have been able to make it work with using one table only, but not with multiple tables.
And how to get the || (concat) to work within my query for my output to an xml file?
Here is my current query:
create or replace function get_xml return clob is
result clob;
qryctx dbms_xmlgen.ctxHandle;
SELECT DBMS_XMLGEN.getxml('select prefix, suffix, fiscal_yr
FROM rcv.recv_accessions ra
where ra.prefix = 8 and ra.fiscal_yr = 11')xml into result FROM dual;
result := DBMS_XMLGEN.getXML(qryCtx);
This is what I desire:
SELECT DBMS_XMLGEN.getxml('select ra.prefix||'-'|| ra.suffix||'-'|| ra.fiscal_yr accession, ss.date_in, st.test
FROM rcv.recv_accessions ra, ser.sero_samples ss, ser.sero_tests st
where ra.prefix = 8 and ra.fiscal_yr = 11 and ss.raid = ra.id and st.ssid = ss.id')xml into result FROM dual;
On this both the reference to multiple tables and the concat function cause errors.
Thank you
Edited by: user583094 on Mar 2, 2011 3:36 PMHi,
for the concat do I use xmlconcat?No, XMLConcat is used to concatenate XMLType fragments.
The || operator will do fine, but you must escape any single quote inside the string :
SELECT DBMS_XMLGEN.getxml(
'SELECT ra.prefix ||''-''|| ra.suffix ||''-''|| ra.fiscal_yr as accession,
ss.date_in,
st.test
FROM rcv.recv_accessions ra,
ser.sero_samples ss,
ser.sero_tests st
WHERE ra.prefix = 8
AND ra.fiscal_yr = 11
AND ss.raid = ra.id
AND st.ssid = ss.id'
INTO result
FROM dual;Or, use the quoting operator to define a custom string delimiter :
SELECT DBMS_XMLGEN.getxml(
q'{SELECT ra.prefix ||'-'|| ra.suffix ||'-'|| ra.fiscal_yr as accession,
ss.date_in,
st.test
FROM rcv.recv_accessions ra,
ser.sero_samples ss,
ser.sero_tests st
WHERE ra.prefix = 8
AND ra.fiscal_yr = 11
AND ss.raid = ra.id
AND st.ssid = ss.id
INTO result
FROM dual;BTW, a good practice would be to use bind variables for the query. DBMS_XMLGEN can handle them nicely :
CREATE OR REPLACE FUNCTION get_xml
RETURN CLOB
IS
qryctx DBMS_XMLGEN.ctxHandle;
v_out CLOB;
qrystr VARCHAR2(4000) :=
'SELECT ra.prefix ||''-''|| ra.suffix ||''-''|| ra.fiscal_yr as accession,
ss.date_in,
st.test
FROM rcv.recv_accessions ra,
ser.sero_samples ss,
ser.sero_tests st
WHERE ra.prefix = :b_prefix
AND ra.fiscal_yr = :b_fiscal_yr
AND ss.raid = ra.id
AND st.ssid = ss.id';
BEGIN
qryctx := DBMS_XMLGEN.newContext(qrystr);
DBMS_XMLGEN.setBindValue(qryctx, 'b_prefix', '8');
DBMS_XMLGEN.setBindValue(qryctx, 'b_fiscal_yr', '11');
-- to generate empty elements if necessary :
DBMS_XMLGEN.setNullHandling(qryctx, DBMS_XMLGEN.EMPTY_TAG);
v_out := DBMS_XMLGEN.getXML(qryctx);
DBMS_XMLGEN.closeContext(qryctx);
RETURN v_out;
END; -
Selecting from multiple tables, into one internal table
Hi,
What is the best & most efficient method of selecting from multiple table (in my case 6,) into one internal table?
Thanks,
John
Points will be rewarded and all responses will be highly appreciated.I have simple example :
First one - Join 5 tables
data : f1 type i,
f2 type i,
f3 type i.
start-of-selection.
get run time field f1.
write the query 4 or 5 tables join.
get run time field f2.
f3 = f2 - f1 ( Total time).
Second one - joins 3 table and use for all entries
data : f1 type i,
f2 type i,
f3 type i.
start-of-selection.
get run time field f1.
write the query 3 tables join and use for all entries
get run time field f2.
f3 = f2 - f1. ( Total time )
Finally you can have time diffrence between the both sql statement. -
Loading Data from multiple tables into essbase using ODI
Hi,
We have a scenario where data comes from multiple tables. I would like to know how will ODI load this data for the right combination of the membersHi,
I take it each data table has a field which maps to the other table. You can just drag the datastores on to the source interface and create a join between the tables.

Reason to do this as these fields are required to be grouped together as they are created in different tables. They are treated as 'attribute' (consists of many columns) of the part number. So, the PL/SQL is requested to design in a way able for user to pass in the column name and column value or part number, then the select statement should be able to query for the records. Another reason is a new column can be added easily without keep modifying those effected programs. Reuseable too.This basically equates to ... hard to code, hard to maintain, and poor performance.
Are you really sure you want to do this? This isn't going to be easy-street as you seem to think it is, but it's a one way street to a poorly performing system with security vulnerabilities (google SQL Injection).
I would highly recommend you reconsider your design decision here. -
Can a block in Oracle contain rows/data from multiple tables?
Hi during my discussion with one of the DBAs, a point came up i.e. A block shouldn't have rows from multiple tables...
Is that true? I read in one of the OTN thread (i don't exactly remember the thread name) that a block can have data from multiple tables. If it doesn't have, what's the table directory in block signifies?
Please share your views.
Thanks,

Hi,
As per the above link,
Table directory
For a heap-organized table, this directory contains metadata about tables whose rows are stored in this block. Multiple tables can store rows in the same block. (Logical Storage Structures)
And by default Oracle creates heap organized tables only.(heap-organized table: A table in which the data rows are stored in no particular order on disk. By default, CREATE TABLE creates a heap-organized table.) (Glossary)
So I can say a block can contain rows from multiple tables. Isn't it?

See Logical Storage Structures
Given: A segment is a set of extents allocated for a specific database object, such as a table.
Given: An extent is a set of logically contiguous data blocks
