Force Multiple Queries / "Stitching" in Union

Is there any way to force OBIEE to execute several queries in parallel when combining several similar queries?
For example, I have a very large fact table with monthly snapshot data. I would rather use combine with similar request option to send similar queries for each month and have OBIEE "stitch" them together. I have seen cases where multiple queries are sent do the database and other cases where one query is generated and sent to the database. Is there a way to force multiple queries to be sent?
Ideally, what I'd like to be able to do is use my time dimension to send always force a query for each month (which is partitioned in the database).

You don't need to do that because it's the work of the database.
When you send a sql query to the database, the query is transformed to generate the best plan and it can be automatically parralelized (As you have partitions, I assume it's the case)
To know more see the paragraph on the optimizer of the database.
http://gerardnico.com/wiki/database/oracle/query_optimizer/start
What about if the database have an aggregate/summary table ? You will send 10 query that can be done only in one.
If you have a performance problem, try to decrease your selectivity by building an aggregate table and use the query rewrite. It's always the best solution.
Obiee offer the aggregate persistence wizzard if you can't access to the database :

A single OBIEE report firing Multiple Queries

HI All,
I tried the search option and did not find any questions which gives me what I am looking for. If I missed it and the question is already asked, please redirect me to the thread.
I had a report which had a data issues. When i checked the log, I was shocked to see it firing 10 different queries. Could you guys please tell me exactly when OBIEE decides to split a single query and fire multiple ones?
Here's some info on the report:
1. All the columns are from the same subject area.
2. All the physical tables are in the same database in the physical layer.
3. All the tables are from the same physical catalog even.
4. Majority of the columns are from the same fact. The fact table however has multiple LTS(Over 30) involving both fragmentation and content filters.
Could you guys please let me know why multiple queries are fired in the above case as well as generally by OBIEE?
Thanks,
Abhiram.

It is recommended not to edit DB features. If you need to change them you might need to take help of oracle support.
Else you might induce more erratic behavior.
Not in agreement here. Depending on how that data sources beneath OBIEE are physically set up and parametrized you may be forced to change this in order to assure performance for example. Not all your BI-analyzed sources will be purpose-built for analytics and hence follow usual modellization rules or approaches. Oracle put the features in the DB objects for exactly that reason. And obviously you don't go and change the features "just like that".
since fact measures are from multiple LTS, every time you bring a measure from different LTS it is treated as another star. So what OBIEE does is it queries each star separately using alias and then stitch them logically. Thats the reason for fragmented queries and a singel long sql in the end with stitches the other sql results in the end.
True, but the OP was talking about "firing 10 different queries". Which is a bit vague but sounds more like distinct select statements rather than stich-joined WITHs...that's why I directed him towards the features which can actually change this dramatically. Problem is, that the OP hasn't made that exact point clear yet.

Multiple Queries in Workbook - Refresh Screen Shows Up for Every Query

We have multiple queries in a workbook. All of these queries have the exact same selections for the variable selection screen. When all the queries are refreshed once, the selection screen used to show up once and all the queries are refreshed with the same selections.
We were on BI 7.0 and SP10. We recently moved to SP12. Since the SP12 installation, the multiple query refresh pops-up the selection screen for every query. It is nothing like "multiple query refresh" at once since the user has to click "execute" button for every single query. It is interesting to note that the selection screen only contains hierarchy variables and hierarchy node variables. The other variables of selection screen do not show up. I couldn't find any OSS note on this topic. Please let me know if anyone has any comments on this issue. I will assign points to useful posts.

Multiple queries in reports with XSL-FO and without BI Publisher

Hello,
I'm trying to find out how to create a complex report in APEX for printing. The report contains multiple queries in different layout, images and static text.
I don't have the possibility to use BI Publisher and I'm not an XSL-FO expert. However I'm trying to find out if it's possible at all not using BI Publisher.
I'm having the impression that multiple report queries and layouts in APEX can only be used in combination with BI Publisher. I'd be glad if someone could give me an example of how to do multiple queries and layout in a single report only using XSL-FO.
Thanks in advance,
Jan Willem

Multiple Queries on Interactive Report

hi all,
Can i run multiple queries based on some condition in creating an interactive report?? I mean
i want to run a single query as
if :P12_QUERY == 1 then
first query
else if :P12_QUERY == 2 then
second query
end if;
Please provide me the syntax if its possible. Plz help me in this regard.
With Regards,
Sunil Bhatia

Hello,
You will need to create a pipeline function and use it in your query. But both your queries have to return the same dataset.
Example:
function choose_query(v_query_type integer) return some_type pipelined
is
v_query varchar2(4000);
v_cur sys_refcursor;
v_row some_type;
begin
if :P12_QUERY == 1 then
v_query := 'select ....';
else if :P12_QUERY == 2 then
v_query := 'select ....';
end if;
open v_cur for v_query;
loop
v_row := some_type(null, null, null);
fetch v_cur into v_row;
exit when v_cur%notfound;
pipe row (v_row);
end loop;
close v_cur;
end;In interactive report you have to set query:
select * from table(choose_query(:P12_QUERY ))

How to execute multiple queries in one stored procedure.

Hi,
I am Kumar,
How to execute multiple queries in one stored procedure.
here is the my requirements,
1. get the max value from one table and sum of the that value.
2. insert the values and also sum of the max value.
using stored procedure
I am using SQL server 2000 database.
Please help me.
Advance thanks

This is not a java question and it is not even a problem: your only problem is
1) lack of knowledge
2) lack of interest to find a manual
But you are going to have to change both by actually reading a book or a manual that explains the stored procedure language of SQL Server. It is the same as Sybase I think, so you could also look for a manual for that DBMS.

Bursting a report with multiple queries

Hi,
I need to set-up bursting in BIP for a report with multiple queries. The output format is pdf and delivery is through e-mail. Since the queries need to be linked, I'm trying to do this using data template. I've set-up split and burst based on a field (store_id) from the first query which is used as a bind variable in the subsequent queries. So I'd ideally want the report to be split based on store_id. The report works fine if I use a parameter for store_id and view the output by store_id. When I try to schedule the report for bursting, it generates and e-mails the reports but only the last report appears to have correct data output while the others have only the output from the first query (and all other queries appear to return nothing in the report).
Any suggestions on what could be the issue here? Thanks!

Hello user6428199,
When you use ":Q1_STORE_ID" in your queries, BI Publisher looks for a report parameter named Q1_STORE_ID. Change all your report queries to get data for all the store_id's available. As you are bursting the report using the store_id as the bursting key, BI Publisher will split the report based on the stored_id and delivers content based on it. No matter how many queries you may have, BI Publisher will loop through all the store_id's available and all the queries will return data for that particular id in a report.
Thanks,
Machaan

Multiple queries with 1 connection

Can I execute multiple queries with one connection?
//Example -
<%
String firstconn;
Class.forName("org.gjt.mm.mysql.Driver");
// create connection string
firstconn = "jdbc:mysql://localhost/profile?user=mark&password=mstringham";
// pass database parameters to JDBC driver
Connection aConn = DriverManager.getConnection(firstconn);
// query statement
Statement firstSQLStatement = aConn.createStatement();
String firstquery = "UPDATE auth_users SET last_log='" + rightnow + "'WHERE name='" + username + "' ";
// get result code
int firstSQLStatus = firstSQLStatement.executeUpdate(firstquery);
// close connection
firstSQLStatement.close();
%>
Now, instead of building a new connection for each query, can I use the same connection info for another query?
if so - how do you do this?
thanks for any help.
Mark

Create multiple statement objects from your connection. It's a good idea to close these in a finally block after you're done with them
Connection conn = null;
Statement stmt1 = null;
Statement stmt2 = null;
try {
    conn = DriverManager.getConnection();
    stmt1 = conn.createStatement();
    // some sql here
    stmt2 = conn.createStatement();
    // some more sql here
} finally {
    if ( stmt1 != null ) stmt1.close();
    if ( stmt2 != null ) stmt2.close();

Can we use multiple queries on one template

Can we use multiple queries on one template

Hi,
if you're using data templates for your data set, you
can put multiple queries in the XML data template.
The queries may then be linked (or not) by the "link
name" tag ...
Grtz.Following you answer here...do you know eventually how/if possible to preview a report (with XMLP Desktop) that is using data templates for the data set?
Thanks,

Multiple queries in a single report?

I'm having some issues with the ColdFusion Report Builder...
I have a database table called "Items" that includes fields
for Reviewer and Status. I want to create a report that will list a
reviewer, then express the number of items where the Status is
"open" as a total or record count. I want to do the same for total
items, and then express the number of "open" items as a percentage.
For example:
REVIEWER, OPEN ITEMS, TOTAL ITEMS, PERCENT OPEN
John Doe, 10, 20, 50%
Jane Smith, 15, 60, 25%
...and so on.
So far I've only been able to get my report to display the
recordcount of the entire query. In order troubleshoot the problem
I created a regular cfm page to do the same thing. Here's what I
did:
<cfquery name="getreviewers"
datasource="#APPLICATION.datasource#">
SELECT DISTINCT Reviewer
FROM Items
ORDER BY Reviewer
</cfquery>
<cfoutput query="getreviewers">
<cfquery name="getopenitems"
datasource="#APPLICATION.datasource#">
SELECT Status
FROM Items
WHERE Status='open'
AND Reviewer = '#Reviewer#'
</cfquery>
<cfset open = getopenitems.recordcount>
<cfquery name="getallitems"
datasource="#APPLICATION.datasource#">
SELECT Status
FROM Items
WHERE Reviewer = '#Reviewer#'
</cfquery>
<cfset all = getallitems.recordcount>
<cfset percent = (open / all) * 100>
#getreviewers.DR_Item_Reviewer#, #open#, #all#,
#Round(percent)#%
</cfoutput>
That worked great, but as you can see I had to nest a couple
of queries inside a <cfoutput>. I don't know how to
incorporate this into the report builder, as it seems you can only
specify a single query. Another thing that occurs to me is perhaps
I'm going about this the wrong way. Is there perhaps a function
that will display things the way I want them without fussing with
multiple queries? Any help would be greatly appreciated. Thanks in
advance.

It seems like you are trying to do a subreport. You can nest
reports within the report feature...just check out the subreport
feature under the help section. If that doesn't help let me
know.

How do I display data from Multiple Queries in a spreadsheet?

I am running Oracle forms 10g as a kicker to export a report (rdf 10.1.2.0.2) to PDF or Excel Spreadsheet - User's choice.
Doesn't matter if I have desformat = SPREADSHEET, DELIMITEDDATA, or DELIMITED; I still get only the first query displayed when I run in spreadsheet format.
How do I display data from Multiple Queries in a spreadsheet? Is this possible?

Hi adam,
did you search the forum? You will find a lot of threads handling the problem of Excel file access.
In short: you need to use ActiveX (the RGT also uses ActiveX under the hood)!

Report with Multiple queries too slow in BI Publisher 11g

Hi, I have a report in 11g where i need to create multiple queries to show them in report. I tried to combine everything in one query, but i found that the query is too huge and hard to understand and maintain. I created 3 data sets and linked them together. In SQL dev, the main query is returning about 315 records and first detail query returns less than 100 records and second detail query is returning one record which is BLOB. Each query returns data within a couple of seconds from SQL Developer. The entire report from BI Publisher should be just 21 page PDF output. Did anyone face performance issues while running reports with multiple queries in 11g? I ran reports that have single query which returned 10K pages PDF and never had an issue while everthing is in one query. This is the first time Iam attempting to create multiple queries. Can someone help me understand what i might be doing wrong or missing here. Thank you.

Isn't there a way for you to do this via a Package/Procedure versus having multiple queries?
Per the BI Publisher guide,
Following are recommended guidelines for building data models:
Reduce the number of data sets or queries in your data model as much as possible. In general, the fewer data sets and queries you have, the faster your data model will run. While multiquery data models are often easier to understand, single-query data models tend to execute more quickly. It is important to understand that in parent-child queries, for every parent, the child query is executed.
You should only use multiquery data models in the following scenarios:
To perform functions that the query type, such as a SQL query, does not support directly.
To support complex views (for example, distributed queries or GROUP BY queries).
To simulate a view when you do not have or want to use a view.

Question about templates with multiple queries

I am just starting out with BI Publisher, v.10.1.3.2. I have a report that has multiple queries, but my template is just based on 1 query. How can I make the template use more than one query?
Thanks!!

Moving multiple queries from one category to another in QM

Hi All,
Is there is any way of moving multiple queries from one category to another in the query manager?
Or is the only way of doing it by saving each one individually into a different category.
Any ideas ?
Regards,
Rakesh N

Hi Rakesh,
The query manager has limited function compare with normal file management applications. Under current design, you have to do this one by one. You just need to make sure move the smaller amount of queries to large category. Category name can be changed easily.
Thanks,
Gordon
