How to extract data from multiple tables (always got errors)

Dear Experts,
I have a simple mapping to extract data from multiple tables as a source (A, B, C) to a target table (X). Below is the picture:
(Sources)....(Target)
A----------------***
B----------------X
C----------------***
Sample Source Data:
Table A:
ColA1
100
200
etc
Table B:
ColB1 ColB2 ColB3
10 Y Ten
20 Y Twenty
30 Y Thirty
etc
Table C:
ColC1 ColC2
11
12
13
etc
Target table (X) should be (just has 1 group INGRP1):
ColA1 ColB1 ColB3 ColC1
100 10 Ten 11
100 10 Ten 12
100 20 Twenty 21
etc
Scenarios:
1. Directly map from A, B, C to X. Unable to map with error message: "API8003: Connection target attribute group is already connected to an incompatible data source. Use a Joiner or Set operator to join the upstream data first before connecting it into this operator."
2. Map each source to Expression Operator and then map from each Expression to target table. I am able to map all attributes successfully but got error when validating it with message: "VLD-1104: Attributes flowing into TEST.EXPR_SRC.INGRP1 have different data sources."
How can I achieve the correct mapping for this purpose?
Use Joiner? I have no key to join the sources
Use Set? The sources have different number of columns
Thanks in advance
Prat

Thanks Nico,
I think it will results data like this:
100 10 Ten 11
200 20 Twenty 12
300 30 Thirty 13
etc
and not the expected:
100 10 Ten 11
100 10 Ten 12
100 20 Twenty 21
etc
But it inspired me to solve this by adding key expression in each source table (B & C) to be joined to table A with this formula:
100+TRUNC(INGRP1.COLB1,-2)

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
Kumar

Hi 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

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.

Records from multiple tables

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.

Does ODI has ability to extract data from multiple tables

We have requirement using ODI to extract data from multiple tables depending on certain logic and spool 100+ files.
How efficient ODI is in data extraction from several multiple tables especially when the extraction is dependent on certain business logic conditions ? Also, if anyone used Peoplesoft Application Engine process to extract volumes of data, how efficient Peoplesoft Applicaiton Engine process is as compared to ODI ? I will really appreciate if someone throws some light on this ? Thanks in advance.

One more option
Create two Integration Interfaces and launch them sequentially:
1st Interface : select a IKM ... Append and activate the Distinct rows check box.
2nd Interface : select an IKM ... Incremental Update and set the UPDATE option to No.
Be aware that the update key in this Integration Interface should be composed of all the target columns mapped. Also activate the Distinct rows check box.
Thanks,

Need assistance searching records from multiple tables - Please Help!

Hi, I've been trying to solve this problem for several weeks now, and I have exhausted all of my knowledge and experience. I need help, and I hope someone here can give me some direction.
I am using VB 2008, and the CR that comes bundled with VS 2008 Pro. My database is a SQL Server 2005 CE v3.5 (a *.sdf file). I am connecting to the database through a dataset, and I am displaying the report in a CrystalReportViewer.
My dataset consistes of two tables:
1) tblCustomers which has a primary key "CustID", and contains only customer contact and personal information.
2) tblDateVisited which has a primary key of "VisitID", but it also has a column titled "CustID". Basically, every time a customer visits the business, details of that visit are recorded in tblDateVisited, and that record is associated with the customer by their CustID.
Here's what I'm trying to accomplish: I want to be able to display only Customer records when the customer has visited and that visit matches certain criteria. Right now, I am trying to match visits from the "tblVisitDate.PlayerType" column. If the customer has ever had a visit where they matched a particular player type, I want to see those customer records.
I don't know what I'm doing wrong, though. I can search a dataset if I am only querying one table and pulling records from that table. However, whenever I try to add a second table and perform queries on that table to get records from the first table, I can't return any records.
If it helps, I am trying to use one CrystalReportViewer to display multiple reports (user choice) and here's how I'm loading the report into the viewer:
Me.tblCustomersTableAdapter.Fill(Me.dsPlayerTypeReports.tblCustomers)
Me.tblDateVisitedTableAdapter.Fill(Me.dsPlayerTypeReports.tblDateVisited)
Me.ReportFile.SetDataSource(dsPlayerTypeReports.Tables(1))
I am suspicious that my problem is in the Tables(1) method. It confuses me that I can only assign one table as a datasource when I obviously need access to two tables to make this selection work.
Whatever the case, I'm at the end of my rope with this one. I'm not prone to giving up, but I'm at a dead end currently.
Any attempt to assist me with this will be greatly appreciated, successful or not.
Thanks in advance!

No, I am connected via ADO.NET. I don't think SQL CE can connect through ODBC (or if it can, I haven't been able to figure out how, yet). So this isn't a stored procedure.
When I examine the link, I can only choose an Inner Join or a Left Outer Join. Right Outer and Full Outer are not available. Could this be a problem with the dataset I'm using?
Could you explain what you mean by display all of the records and then choose the selection criteria?

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 Maurya

hi 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

Extracting data from multiple tables using DB connect

Hi,
I am having different tables which are having the same structure in oracle database but there names are different.Now i have only one datasource at BI side.This datasource shld extract data from the tables dynamically.How can i do it using DB Connect .
Thnxs

ahh I see - problem as you said then is if you then take on a new location!
I would then put into the source system a table identifier and create a view across all the tables
Then dbconnect from the view and use the selection parameter of table parameter if you wanted one infopackage per "location"
If you do need to have a new table in the source then just expand the view and create a new ipak
hence NO bw changes required that need a dev-q-p transport - just the ipak in prod and it;s the source systems problem to add the extra table to the view

Search a record from Multiple Tables

Is there a pl/sql command or way that searches for a specific record (text, number) in multiple tables? Given that you don't know the column you are searching from.

There is no built in method, but you can roll your own.

Using ResultSet to read records from multiple tables

Im using a ResultSet object to read records from tables.
I have a database with 5 tables. Initially, I got it to work fine with one of those tables. What Im exactly trying to do is check if there is a record in a table which matches a given string, and if it does, display some text on some JTextFields. I got that to work fine with one table.
Problem is, how do I get it to work with all 5 tables at the same time?
i.e. instead of searching through one table, I want it to look through all 5 tables and look for the matches.
Any help greatly appreciated.
Thanks

After the first interaction with the first table, I
used a stmt.getMoreResults() followed by instructions
to get data from the second table, and so on.
Worked fine.Sounds remarkably inefficient. (Potential for lots of network traffic.)
is this another way of doing it?Sounds more like a document search type of thing than a database query. What about Lucene? Could it help here?

How i extract like this data . Please let me know

Hi,
you need to create a generic extractor using a function module for this. For some help check this: /people/siegfried.szameitat/blog/2005/09/29/generic-extraction-via-function-module
Additionally you can get a template from me. You'll find my email in my business card.

Records from multiple table in Forms using Structure

Hi all,
I thought of bringing records from more than one table to smart forms.I have done the same by using two internal tables but not using with globally declared structure.Is it like this:
1.Create the global structure
2.In driver program create a internal table
3.Pull the data using select statement
4.Pass the internal table to smartforms-> Here I dont understand how.Usually In smartforms we declare internal tables of table type like 'itable type zgkmaster'
How to pass the internal table we created using structure to smartforms?
Thanks

Hi Gopi,
the procedure u r telling is correct.
create the structure(ex:zstruc) in se11 as the structure of the internal table.
*popluate the data into internal table.
*in smartform, u declare the internal table as that structure i.e itab type zstruc.
i.e in smartforms when u declare internal table, u r telling that ur internal table having the structure similar to the structure ZSTRUC.
In smartforms u can declare the table type using either ...type <db table> or ... type <structure>.

Problem selecting records from multiple tables

Good day
I am writing a report showing actual vs budget amount per period. The actual amounts are in one table and the budget amount are in another table. In this example it is for vehicle sales. The problem is that in the budget table, there are no records for a particular make if it was not budgeted to make a sale. If I try to get the records using the select expert it matches the key in actual table with key in budget table and retrieve. What happens then is that the records in the actual table get excluded if there was not a record for it in the budget table. How do I then do this selection, i.e. if there is a record in the budget table, then retrieve, otherwise make the budget amount 0?
Thanks
Wilhelm

This is always difficult the best way is to use a command and union the two sets of data.
First part uses a left outer join from Actual to Budget and brings back all actual data with and without a budget.
Second parts brings back data from budegt where nothing exists in actual
select (field list) from
Actual a
left outer join Budget b on a.field = b.field
where (any other filter condition)
union all
select (field list) from
budget b
left outer join actual a on b.field = a.field and a.field is null
where (any other filter condition)
You can get the first query from your current report and the modify to build the second unioned query.
