How to use muti-thread to query database?

if i want to use two or more threads to query a database for data,what should i do?anybody know?

Hi,
I have 2 suggestions to help you do this.
First, the Berkeley DB XML Transaction Guide uses has a multi-threaded application and several discussions about DB_THREAD.
For more information see:
http://www.oracle.com/technology/documentation/berkeley-db/xml/gsg_xml_txn/cxx/introduction.html#multithread-intro
The following section should also be useful:
http://www.oracle.com/technology/documentation/berkeley-db/xml/gsg_xml_txn/cxx/txnconcurrency.html#concurrenthandles
If after reading about this and trying to implement you have a specific question, please post it here.
You might also take a look in the Berkeley DB examples, TxnGuide.cpp which is a multi-threaded application.

How to use the same POWL query for multiple users

Hello,
I have defined a POWL query which executes properly. But if I map the same POWL query to 2 portal users and the 2 portal users try to access the same page simultaneously then it gives an error message to one of the users that
"Query 'ABC' is already open in another session."
where 'ABC' is the query name.
Can you please tell me how to use the same POWL query for multiple users ?
A fast reply would be highly appreciated.
Thanks and Regards,
Sandhya

Batch processing usually involves using actions you have recorded. In Action you can insert Path that can be used during processing documents. Path have some size so you may want to only process document that have the same size. Look in the Actions Palette fly-out menu for insert path. It inserts|records the current document work path into the action being worked on and when the action is played it inserts the path into the document as the current work path..

How to use Key Date in query

Imagine an invoice was created for a customer on the 1st of January 2008 for £1000
On the 1st of Feb, he paid $300, owing $700
On the 1st of Mar, he paid $450, owing $250
On the 1st of Apr, he paid $250.
If I run an AR report today the 10th of Aug, I would see he owes nothing. What I want to do is to run the report today based on the 2nd of March and see a debt of £250. I dont want to use the posting date in the selection criteria henceI think this is the case when you use a key date but Im not sure how to use this in the query properties of BI7. What Characteristic do I need to specify as time dependant? Is there anything else I should consider?

hi,
Key Date setting is for the 'time dependent' master data.
Lets say u have a Characteristic MATERIAL with a time dependent attribute MATERIAL GROUP as follows.
MATERIAL FROM TO MATERIAL GROUP
ABD 01/01/1995 12/31/2003 X
ABD 01/01/2004 12/31/9999 Y
Depending on what you have for the Keydate, the Material group is selected.
If your key date is, ex, 06/12/2001 there material group is X. Or if key date is 02/15/2005, material group is Y.
If you do not enter any value for keydate, system automatically assumes today' date.
hope it helps..

Powershell use Connection String to query Database and write to Excel

Right now I have a powershell script that uses ODBC to query SQL Server 2008 / 2012 database and write to EXCEL
$excel = New-Object -Com Excel.Application
$excel.Visible = $True
$wb = $Excel.Workbooks.Add()
$ws = $wb.Worksheets.Item(1)
$ws.name = "GUP Download Activity"
$qt = $ws.QueryTables.Add("ODBC;DSN=$DSN;UID=$username;PWD=$password", $ws.Range("A1"), $SQL_Statement)
if ($qt.Refresh()){
$ws.Activate()
$ws.Select()
$excel.Rows.Item(1).HorizontalAlignment = $xlCenter
$excel.Rows.Item(1).VerticalAlignment = $xlTop
$excel.Rows.Item("1:1").Font.Name = "Calibri"
$excel.Rows.Item("1:1").Font.Size = 11
$excel.Rows.Item("1:1").Font.Bold = $true
$filename = "D:\Script\Reports\Status_$a.xlsx"
if (test-path $filename ) { rm $filename }
$wb.SaveAs($filename, $xlOpenXMLWorkbook) #save as an XML Workbook (xslx)
$wb.Saved = $True #flag it as being saved
$wb.Close() #close the document
$Excel.Quit() #and the instance of Excel
$wb = $Null #set all variables that point to Excel objects to null
$ws = $Null #makes sure Excel deflates
$Excel=$Null #let the air out
I would like to use connection string to query the database and write results to EXCEL, i.e.
$SQL_Statement = "SELECT ..."
$conn = New-Object System.Data.SqlClient.SqlConnection
$conn.ConnectionString = "Server=10.10.10.10;Initial Catalog=mydatabase;User Id=$username;Password=$password;"
$conn.Open()
$cmd = New-Object System.Data.SqlClient.SqlCommand($SQL_Statement,$conn)
do{
try{
$rdr = $cmd.ExecuteReader()
while ($rdr.read()){
$sql_output += ,@($rdr.GetValue(0), $rdr.GetValue(1))
$transactionComplete = $true
catch{
$transactionComplete = $false
}until ($transactionComplete)
$conn.Close()
How would I read the columns and data for $sql_output into an EXCEL worksheet. Where do I find these tutorials?

Hi Q.P.Waverly,
If you mean to export the data in $sql_output to excel document, please try to format the output with psobject:
$sql_output=@()
do{
try{
$rdr = $cmd.ExecuteReader()
while ($rdr.read()){
$sql_output+=New-Object PSObject -Property @{data1 = $rdr.GetValue(0);data2 =$rdr.GetValue(1)}
$transactionComplete = $true
catch{
$transactionComplete = $false
}until ($transactionComplete)
$conn.Close()
Then please try to use the cmdlet "Export-Csv" to export the data to excel like:
$sql_output | Export-Csv d:\data.csv
Or you can export to worksheet like:
$excel = New-Object -ComObject Excel.Application
$excel.Visible = $true
$workbook = $excel.Workbooks.Add()
$sheet = $workbook.ActiveSheet
$counter = 0
$sql_output | ForEach-Object {
$counter++
$sheet.cells.Item($counter,1) = $_.data1$sheet.cells.Item($counter,2) = $_.data2}
Refer to:

If there is anything else regarding this issue, please feel free to post back.

How to use multiple threads and swing for displaying status/interaction

I have a Swing-app which have to show progress and allow userinteraction for these tasks:
* First:
retrieve a list of IDs(String) from the database (single thread running)
* Second:
some work on the id-list and list written to hd (same thread as above)
* Third:
retrieve Objects (based on the id-list) from different sources (Multiple Threads are running)
To show the status I have a JProgressBar (indeterminate while task1&2 running) and
a JTextArea showing the current status (connect,retrieve list, sort, ...)
When task3 is starting the JTextArea have to disappear and be replaced by a ScrollPane
with an array of Labels/TextAreas showing the status of each thread.
While theses threads are working, the ID-list will be consumed and the JProgressBar
shows the remaining precentage of the hole progress.
Everything is working so far (excepts UI :) , the problem(s) I have:
I need the threads to interacts with the user through the ui. e.g: "Connection to db-xyz lost! reconnect?"
But I don´t know how to do this correctly.
I think one way would be to send an event to the ui... but how?
(the ui must know which thread is calling to unpause it after user answered)
I know that threads should NOT change the swing(-container) - How do I notify the ui that a thread has a question?
Since these threads are really time-consuming the UI is not updated frequently,
how can I increase this? (perhaps using another thread-priority?)
thanks for help!

if/when your threads need to interact with the UI, they can create a Runnable & send it to SwingUtilities.invokeLater or invokeAndWait. This Runnable can popup a message to the user, and act on the choice of the user (reconnect, cancel, ...). This action could be something which "unpauses" the task thread.
You may need to do synchronisation between the code in the Runnable & the Thread to which it is related - so the latter Thread knows when the user has made the choice.

How to use a thread as daemon thread

In multithreading i have undergone through daemon thread concepts and its mentioned as low priority thread which runs in the background of garbage collection.
My query is how to make the thread daemon thread r we going to use thread priorities here.
Can anyone demonstrate with an example reg this. I will be very much thankful to them.

In general, threads that run application code are not daemon threads, and threads that run system code are daemon threads,so the daemon attribute is queried using the isDaemon() method; it is set using the setDaemon() method.....

How to use Results from Another Query for SAP BW universes

Hi Everyone,
I have two SAP BI universes.In my First universe I have Sales Doc no (dimension) and Orderqty (Measure) and in my second universe I have Sales Doc no(Dimension) and BillQty (Measure).
Here in my first dataprovider I have 1200 rows of data and in second dataprovider I have 75,000 rows. The report should fetch only the BillQty details that matches to corresponding Sales doc no in first data provider.
I want to place all these fileds into a single report like as shown.
(Datarpovider1) (Datarpovider1) (Datarpovider2)
*Sales Doc No* Orderqty BillQty
Here I am able to generate single report using merge dimension but it is leading to performance issues. I want to restrict the values at query level by passing the First dataprovider Sales doc no to second Data provider Sales doc number using Results from Anothery Query feature so that It can fetch only the matching records.
I tried it but it was giving the follwing error:
A filter contains a wrong value. You cannot run this query. (Error: WIS 00007)
How Can I get rid of this error. Can we use Results from Anothery Query option for OLAP universe. Are there any limitation on it.
All this I am doing in Webi Rich Client.
Appreciate your help
Thanks &in Advance
Kiran Saka

Hi Kiran,
I think the filter has a wrong operand. For example, a filter with an empty constant, or a filter that deals with numeric values is defined with an alphanumeric value.Check out for this.

How to use the not exists query

Hello,
Using obiee 11g,
i would like to know how to deal with not exists query in the obiee11g,
the query is like this
select count(a.col1),a.col2 from table1 a ,table2 b where a.col1=b.col1
and not exists
(select d.col1 from table3 d, table4 e
where d.col1=e.col1 and d.col1=a.col1)
group by a.col2
there are 4 tables.
table1,table2,table3,tabel4
this is what i need in a report,these tables are used in othere places also,
would prefer if its possible to do in for a report i.e.e analysis itself.
If not possible then may be in rpd since if i change in rpd it may reflect every place
and not in for a report itself.
thanks

Implement this in report itself can be a tricky and tedious job..But better to have it in RPD - Physical - Select Table type
USE NOT IN in place of NOT Exist..You can simply use SELECT statement in SELECT TABLE TYPE
Hope it clear

How to use Native XA in XE database?

I am having problem in using XA datasource in XE. I understand if we are using XE database, jvm is not available. Thus, we have to use Native XA which requires using JDBC Thin Driver.

Can anyone help to enlighten?
Or maybe provides me with basic configuration of using XA datasource in XE database so I can check whether my config is correct or not?
Any help will be appreciated!
Thanks before.
Joel

Hi,
Here's an update regarding my problem with XA transaction using XE.
I don't know exactly how, but it works now.
Here are the steps I did :
===================
1. I decided to try creating JAVA_XA package in XE database. I took the script
from oracle enterprise edition.
This package can't be compiled in XE Production version, but it can be compiled
in XE beta version.
2. After using compiling, the JBoss initialization was still failing.
3. Backup the database (with JAVA_XA) , and upgraded the beta-version to
Production version.
4. Restore the database (with JAVA_XA) into the Production version.
5. it works :))
Hopefully I can get some inputs/comments from the experts here in the forum.
Thanks for those who has responded to my previous posts.
Regards,
Yoel
Good job! A nice extra mile.

How to use wildcards in ABAP query where condition?

Hi,
Please tell me how to use wildcards in ABAP qurey where condition.
e.g. select * from mara where matnr = * (wildcard we need to use.
Thanks & Regards,
Gaurav T

Do you want to query asterix * ?
select * from mara where matnr = '*'. "then just put it in apstrophes
or you want certain part of string be used as * ?
select * from mara where matnr like '%*' "then use % sign before it
or maybe you want something like this
select * from mara where matnr like '%1' . "then it will look for all materials having '1' inside it
