Reg. Multiple Result set in OBIEE

Hi All,
I would like to have some pointers or any documentation reg. the processing of mutiple result sets from a DB2 stored procedure, by the OBIEE layer.
Thanks in Advance,
Rocky

Hi Radha,
If you want to cache the results in the Oracle BI Server, you should check that option. When you run a query the Oracle BI Server will get its results from the cache, based on the persistence time you define. If the cache is expired, the Oracle BI Server will go to the database to get the results.
If you want to use caching, you should enable caching in the nqsconfig.ini file.
Cheers,

Stored Procedure With Multiple Result Sets As Report Source : Crosspost

Hello Everyone,
I have an issue where i have created a stored procedure that returns multiple result sets
/* Input param = @SalesOrderID */
SELECT * FROM Orders TB1
INNER JOIN OrderDetails TB2 ON TB1.ID = TB2.ID
WHERE TB1.OrderID = @SalesOrderID
SELECT * FROM Addresses
WHERE Addresses.OrderID = @SalesOrderID AND Addresses.AddressType = 'Shipping'
SELECT * FROM Addresses
WHERE Addresses.OrderID = @SalesOrderID AND Addresses.AddressType = 'Billing'
This is just a quick sample, the actual procedure is a lot more complex but this illustrates the theory.
When I set the report source in Crystal X to the stored procedure it is only allowing me to add rows from the first result set.
Is there any way to get around this issue?
The reason that I would prefer to use a stored procedure to get all the data is simply performance. Without using one big stored procedure I would have to run at least 6 sub reports which is not acceptable because the number of sub reports could grow exponentially depending on the number of items for a particular sales order.
Any ideas or input would be greatly appreciated.
TIA
- Adam
P.S
Sorry for the cross post, I originally posted this question [here|/community [original link is broken];
but was informed that it might be the wrong forum

Adam, apologies for the redirect, but it is better to have .NET posts in one place. That way anyone can search the forum for answers. (and I do not have the rights to move posts).
Anyhow, as long as the report is created, you should be able to pass the datasets as:
crReportDocument.Database.Tables(0).SetDataSource(dataSet.Tables("NAME_OF_TABLE"))
Of course alternatively, (not sure if this is possible in your environment) you could create a multi-table ADO .NET dataset and pass that to the report.

Handling Multiple Result Sets

Hi
I have a problem while handling multiple result sets. To fix that problem i need to upgrade my JDBC version2.0 to 4.0.
My Problem is that i dont know which jars need to be downloaded to upgrade my JDBC version.

How dynamically genrate result set in OBIEE 11.

I have variable in OBIEE 11 dashboard report that contains a comma separated string
represented by Fact table columns as below are 3 columns of Fact table Unique Clicks, No of Prospects,
and Email Sent Count
Var = “Fact”.”Unique Clicks”,”Fact”.”No of Prospects”,”Fact”.”Email Sent Count”
Now I want to separate these columns and generate columns of result set in OBIEE 11 dashboard report
In other word dynamically generate result set columns.
Can I do through java script, changes in analysis XML shown in Advanced tab etc any syggestion.

Oracle 8.1.6 Thin Driver with Multiple Result Sets

We're using Oracle 8.1.6 on NT using the latest driver release.
Java 1.2.2
We're experiencing problems with resultSet.next when we have multiple result sets open. What appears to be happening when you've read the last result set entry do a .next() call which should result in a false value we actually get java.sql.SQLException: ORA-01002: fetch out of sequence.
This seems to us that the driver is trying to go beyond the end of the result set.
We've checked JDBC standards (and examples on this site) and the code we've got is compliant. We've also found that the code produces the correct results under Oracle 7.3.4 and 8.0.4.
I can also say that there is no other activity on the db, so there are no issues such as roll back segments coming into play.
Any solutions, help, advice etc would be gratefully appreciated!

Phil,
By "multiple result sets open", do you mean you are using REF Cursors, or do you have multiple statements opened, each with its own ResultSet? If you could post an example showing what the problem is, that would be very helpful.
You don't happen to have 'for update' clause in your SQL statement, do you?
Thanks

Reading multiple result sets using executeQuery

Hi - We have a database Proc that returns multiple result sets as the out params.
Following is the line that does the DB call.
rows = DynamicSQL.executeQuery(sentence : query, implname : "Sql Server");
The 'rows' param above is able to get only the first result set after. It ignores the rest of the Out params.
Do we have any way other than changing the proc to send one out param to handle this?
Thanks!
VVP

This worked:
rows = myDynamic.executeQuery(sentence : SaveQueryForMAPS, implname : "MAPS");
foreach (row in rows) {
//status = 0;
status = row[1];
display("status" +status);
Thank you so much for your idea Andrea!

Callable Statatement returning multiple Result Sets

Hello all,
I've got a stored procedure that will be returning multiple result sets and i was wondering if someone could show me how to pull the multiple result sets out of the CallableStatement object. Any help would be greatly appreciated.

Here is a sample that does what you want. You will have to substitute the call to DBConn.getConnection() with your own DB connection. Also remove the import of com.ovotron.util.*.import com.ovotron.util.*;
import java.sql.*;
public class MultiSQL {
    private static Connection conn = null;
    public static void main(String[] args) {
        // Just gets a connection to the DB.
        conn = DBConn.getConnection();
        getResults(conn);
    * Cycles through multiple result sets returned from a stored procedure.
    * Only the first column is output.
    * <p>
    private static void getResults(Connection conn) {
        // Not sure which DBMS you are using. This is the syntax for
        // SQLServer V7.0.
        String            sql     = "{call getMultiResults}";
        CallableStatement stmt    = null;
        ResultSet         rs      = null;
        int               setNo   = 0;
        try {
            stmt = conn.prepareCall(sql);
            boolean found = stmt.execute();
            while (found) {
                setNo++;
                rs = stmt.getResultSet();
                while (rs.next()) {
                    System.out.println("Result set " + setNo +
                                       ": value: " + rs.getString(1));
                    System.out.flush();
                rs.close();
                found = stmt.getMoreResults();
        catch (SQLException e) {
            e.printStackTrace();
        finally {
            try {
                if (rs   != null) rs.close();
                if (stmt != null) stmt.close();
            catch (SQLException e) {
                // Tried already to clean up.
}The procedure I used is:CREATE PROCEDURE [getMultiResults] AS
select col1 from tab1;
select col2 from tab1;
select col3 from tab1;Of course you will need to create and populate tab1.

Multiple result sets from stored procedure into CachedRowSet

How can you obtain multiple sets of data from a stored procedure that returns multiple result sets, when you'd like to use CachedRowSet rather than ResultSet?
My database's stored procedures return multiple result sets, but I'm not sure how to manipulate that using CallableStatements and CachedRowSets... I read the RowSet tutorial from java.sun.com but that didn't cover the case of multiple result sets and CallablStatements.
How might I do this? Thanks a lot.

SELECT columns..
FROM table
FOR XML PATH('NodeName'),('Rootname')
Thank you for replying.
I dont have to generate XML from a query. I have to generate from a SP and that too without modifying it.
Thanks,
Tauhid
thats ok you can do like this
1. Create a table with structure same as SP resultset
2. Populate table with SP result as per below
INSERT table
EXEC SPName param1value,...
3. Add a query like below
SELECT columns..
FROM tablename
FOR XML PATH('NodeName'),('RootName')
see

How to use stored procedure which returns result set in OBIEE

Hi,
I hav one stored procedure (one parameter) which returns a result set. Can we use this stored procedure in OBIEE? If so, how we hav to use.
I know we hav the Evaluate function but not sure whether I can use for my SP which returns result set. Is there any other way where I can use my SP?
Pls help me in solving this.
Thanks

How do you report from a multiple-result-set stored procedure?

Team,
I am writing a report against a canned stored procedure which returns eight result sets. That is, inside the stored procedure, there are eight SELECT statements which pump to the output. In ADO, you would read the first one, then use SqlDataReader.NextResult to advance the reader to the next one until you have done all eight.
Q1: Have you ever written a Crystal Report against such a sproc? How?
Q2: I see that I could pull this data using ADO.NET if I knew this: Have you ever read such a sproc into a dataset? When I drag-and-drop the sproc into the dataset designer, it only makes a table schema for the first result set. I desire to have a table schema for all eight.
Thanks,
~ Shaun

Q1: Have you ever written a Crystal Report against such a sproc? How?
- best answered in the Crystal Reports Design forum, so please post there:
SAP Crystal Reports
Q2: I see that I could pull this data using ADO.NET if I knew this: Have you ever read such a sproc into a dataset? When I drag-and-drop the sproc into the dataset designer, it only makes a table schema for the first result set. I desire to have a table schema for all eight.
- not a Crystal reports question. Perhaps better posted to some MS / .NET developer forum(?)

SQL Server 2012: Import and Export Wizard - Exporting Multiple Result Sets at Once?

I'm working in SQL Server 2012 trying to export some data from our database into an Excel file. My SQL statement has two separate Select statements. They are not joined by a union. When I Execute them inside of SQL Server Management Studio, with Results
set to go to a Grid, I get two result sets back. Two full tables of data.
However, when I use the Import and Export Wizard, the Excel sheet only has the first set of data.
What do I need to do to have it so both result sets show up in the excel file?

Why cant use merge them using union/union all if intention is to get them to same sheet? Is it like the metadata is different so that they cant be merged to single sheet?
If that being the case you need to do it in two steps.

Populating multiple result sets properly

Hi,
I am attempting to create 2 resultsets within a servlet from a mysql db.
I am at present creating 2 connections, query strings. statements and resultsets but my second resultset is not being populated correctly and is null.
Is there something wrong with my implementing 2 result sets like this? and if so, how should I create 2 resultsets? I have posted my code below.
Thanks
Connection con = DriverManager.getConnection( url, "root", "password");
//2nd connection for second result set processing
Connection con2 = DriverManager.getConnection( url, "root", "password" );
Statement stmt = con.createStatement ();
Statement stmt2 = con2.createStatement ();
ResultSet rs = stmt.executeQuery (query);
ResultSet rs2 = stmtAI.executeQuery (query2);
printResultSet ( resp, rs );
useSecondResultset ( rs, rs2 );
rs.close();
rs2.close();
stmt.close();
stmt2.close();
con2.close();

You shouldn't have ResultSets in a JSP, IMO.
JSPs are only for display. And scriptlet code is not a good thing.
Move that SQL stuff into a Java Bean that you can set off line. Have that bean take the data out of ResultSets and put it into a data structure or object and immediately close the ResultSet.
Once you get it running, have the JSP call its methods and access the results from the object or data structure.

Returning multiple result sets

I would like to populate multiple tables in a typed
DataSet in a single call to OracleDataAdapter.Fill
(one round trip to the database). I have found examples
that do this with REF CURSOR output parameters from a
stored procedure that is defined in a package. However,
my SELECT statements are dynamically generated. Is there
any way to execute multiple dynamic SELECT statements in
a single Command used by OracleDataAdapter.Fill? Or is
there some other way to do this with dynamic SQL?
Thanks,
Dennis
[email protected]

Neeraj,
I tried doing this, but the call to Fill did not put any
rows into my DataSet when using an anonymous SQL block.
Do you have a working example that you could sent to me?
Thanks,
Dennis
Here's the stored procedure, which works:
CREATE OR REPLACE PACKAGE BODY cr_mccarthyd_odpnet AS
PROCEDURE GetAttributes (DefCur OUT RefCur,
ValCur OUT RefCur)
IS
LocalValCur RefCur;
LocalDefCur RefCur;
BEGIN
OPEN LocalDefCur FOR
Select * from ATTRIBUTES;
OPEN LocalValCur FOR
Select * from ATTRIBUTE_VALUES;
DefCur := LocalDefCur;
ValCur := LocalValCur;
END GetAttributes;
END cr_mccarthyd_odpnet;
And here's the anonymous SQL block, which does not throw
an error, but does not produce any data either:
DECLARE
TYPE RefCur IS REF CURSOR;
LocalValCur RefCur;
LocalDefCur RefCur;
BEGIN
OPEN LocalDefCur FOR
Select * from ATTRIBUTES;
OPEN LocalValCur FOR
Select * from ATTRIBUTE_VALUES;
END
Finally, here is the C# calling ODP.NET:
               // Open a connection.
               OracleConnection conn = new OracleConnection("Data Source=CR-DEV;User ID=CR01;Password=CR01");
               conn.Open();
               // Create a command for calling the stored procedure.
               OracleCommand cmd = new OracleCommand();
               cmd.Connection = conn;
               cmd.CommandText = "cr_mccarthyd_odpnet.GetAttributes";
               cmd.CommandType = CommandType.StoredProcedure;
               cmd.Parameters.Add("LocalValCur",OracleDbType.RefCursor,DBNull.Value,ParameterDirection.Output);
               cmd.Parameters.Add("LocalDefCur",OracleDbType.RefCursor,DBNull.Value,ParameterDirection.Output);
               // Create an adapter to populate the data set.
               OracleDataAdapter adapter = new OracleDataAdapter(cmd);
               adapter.TableMappings.Add("Table", "Attributes");
               adapter.TableMappings.Add("Table1", "AttributeValues");
               // Create the typed data set and fill it.
               TrueNorth.AttributeDataSet dataset = new AttributeDataSet();
               try
                    adapter.Fill(dataset);
               catch (Exception ex)
                    System.Windows.Forms.MessageBox.Show(ex.Message);
               return dataset;

Multiple results set - missing from callablestatement

I am using callablestatement to call a store procedure and it will return several resultsets and my code is kind of like the following:
ResultSet rs = callablestatement.executeQuery();
do {
if (!rs.next()) {
} else {
rsmd = rs.getMetaData();
int col_count = rsmd.getColumnCount();
for (int i = 0; i < col_count; i++) {
// create table headings
do {
for (int i = 0; i < col_count; i++) {
// get data
while (rs.next());
while (callablestatement.getMoreResults() || (callablestatement.getUpdateCount() != -1));
The problem I am having is that if say I am expecting 4 resultsets back, and the 3rd one contains empty row, the above would think there is no more resultset and it will stop and it will never return me the 4th resultset which is non-empty. I think the 3rd resultset is returned as null or something but I am sure.
Has anyone seen this problem or what is the best way to handle multiple resultsets?

Hi,
I can promise you that
No matter how you run your code, you always could get
the last three rows.
Because you have such a instruction
if(!rs.next()) {..}
being run first before you start fetch your rows.
good luck,
Alfred Wu

Thank you for the response.
I used the XMLType and Queue is created so far ok. This queue is actually used through Event Based Queue in Scheduler. Now when i use the XMLTYpe payload and specify that in event_condition as follows in dbms_scheduler.create_job it throws "ORA-25448: rule . has errors".
following is the code. Does this mean dbms_scheduler queue spec does not support XMLType payload?
dbms_scheduler.create_job(
