Can we execute a query in resultset while loop

can we execute a query in resultset while loop
for ex:
rs=st.executeQuery("SQL");
while(rs.next())
rs1=st.executequery("SQL1");
while(rs1.next())
}

If you do this, you lose "rs". Create a second
Statement object for the other query.This is right. We have done it many times, It is not the issue as long as you use different statement with in the body of the loop

JDBC- can u execute a query while processing results

can you execute a query in the while loop of a different resultSet?
e.g.,...
line2= ("Select teamName, played, won, lost, draw, forfor, against, points from leaguetable where tourId = " + tourId);
query4 = stmt.executeQuery(line2);
while (query4.next())
teamName = query4.getString(1);
playedTemp = query4.getString(2);
played = Integer.parseInt(playedTemp);
wonTemp = query4.getString(3);
won = Integer.parseInt(wonTemp);
lostTemp = query4.getString(4);
lost = Integer.parseInt(lostTemp);
drawTemp = query4.getString(5);
draw = Integer.parseInt(drawTemp);
forforTemp = query4.getString(6);
forfor = Integer.parseInt(forforTemp);
againstTemp = query4.getString(7);
against = Integer.parseInt(againstTemp);
pointsTemp = query4.getString(8);
points = Integer.parseInt(pointsTemp);
for (int i=0; i<homeTeams.length; i++){
if(teamName.equals(homeTeams)){
homeTeamScoreInt = Integer.parseInt(homeTeamScore[i]);
awayTeamScoreInt = Integer.parseInt(awayTeamScore[i]);
if(homeTeamScoreInt > awayTeamScoreInt){
played = played + 1;
won = won + 1;
forfor = forfor + homeTeamScoreInt;
against = against + awayTeamScoreInt;
points = points + 3;
line3 = ("Update LEAGUETABLE set played = " + played + ", won = " + won + ", forfor = " + forfor + ", against = " + against +
", points = " + points + " where tourid = " + tourId + " AND teamName = '" + teamName+ "'");
stmt.executeUpdate(line3);
it only works once, it stops at the end of the while loop, i.e., it doesnt loop around the resultSet like it should.

do you mean for this part...
query4 = stmt.executeQuery(line2);
while (query4.next())
surely the data is stored in the resultSet ??
or do you mean this part...
stmt.executeUpdate(line3);

While Rollup is goingon Can we execute the query

Hello All
We have a cube and aggregates built on this cube and daily in my Process chain we have step Rollup.
Now while Rollup is goingon Can we execute the query which is builut on the same cube? Will the cube will be locked?
Can we excute query while load is goingon to this cube?
Regards
Balji

Hi Balaji,
You can execute a query when the roll up is going on. The new data is available to the report only when the rollup is complete, but this will not create locks.
Hope this helps...

How can I execute a query from a BSP application?

How can I execute a query from a BSP application?
I´m trying to execute a Query from intranet. I´ve been looking for examples, but the templates I´ve found doesn´t help me.
does anybody has an example?
Thanks.

Hi
Have you designed the BSP application ?
design it first with one page
page will have layout and Event handlers
Design the layout with the fields
in the event handler there are events
in the event On Initiailization or ON inputprocessing write the select query similar to what we write in routine ABAp and fetch the data into ITAB and that has to be passed to the Layout
see the doc

To learn how to create Web applications with Business Server Pages, you can work through the simple tutorials that build on each other. You should be able to run through all of the steps described here in your own system.
If you want to develop Web applications with BSPs, your system must meet the following requirements: Prerequisites for Creating Web Applications.
The following tutorials are available:
· First Tutorial: First Steps with Business Server Pages
· Second tutorial: A Small BSP Application and A Small BSP Application with HTMLB
· Third tutorial: Our First Online Bookshop
· Fourth tutorial: Further Developing the Bookshop
· A small Tutorial is also available for your first steps with the Model View Controller design pattern.
· For a more complex MVC tutorial based on the third tutorial, see: Our Little Online Bookshop Using MVC and HTMLB
When creating BSP applications, note the browser dependencies described in Note 598860.
steps:
1) start the transaction RZ10.
2) now u u have to select Profile name, so select the INSTANCE Profile from the list of options given with the Profile parameter list.U may find multiple instance profile in the list, so select the profile in which ur server name is given.
3) u will also find three options in the same window.
Administrator data, Basic Maintenance, and Extended Maintenance. So select the last one from that.
4) Now click on change button.
5) here u will find parameter icm/host_name_full, so now set it as FQDN.
6) Now copy ur settings with new version number.
7) Activate that version.
8) And now please restart ur WAS.
So this will set ur FQDN, and also don't forget to login using Admin User.
Now u also check for following service are active in your ICF setting or not,( just start transaction code SICF)

How Can I Execute Sql Query in Managed bean?

Hi,
I want to execute sql query in managedbean and get the query result. How can I do?
Best wishes!

You can do this by having current Database connection your application is using like this
public static synchronized DBTransaction getDBTransaction(){
FacesContext ctx = FacesContext.getCurrentInstance();
ValueBinding vb = ctx.getApplication().createValueBinding("#{data}");
BindingContext bc = (BindingContext)vb.getValue(ctx.getCurrentInstance());
DataControl dc = bc.findDataControl("AppModuleDataControl");
ApplicationModuleImpl am = ((ApplicationModuleImpl)(ApplicationModule)dc.getDataProvider());
return am.getDBTransaction();
and then user DBTransaction object to create Statement and PreparedStatement you can find those in java doc.

How can I execute a query using RSCRMBW_REPORT?

Hi everybody,
I have read the document:
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/3ba5e590-0201-0010-59b1-cab51fd245b7
and found it is very intersting for my requirement.
I copied the report,and modified it regarding our case.But during the second call,I get runtime error.
I debugged the code, and found the error results from method GET_CUBETYPE() of class CL_RSCRMBW_BAPI.In this method,it tries to create a object which is TYPE REF TO cl_rsd_dta.
CREATE OBJECT lr_dta
     EXPORTING
       i_infoprov    = g_s_status-infocube
But g_s_status-infcube is null.
I am not able to find where this 'infocube' component in this g_s_status struction is filled,even I found,I don't know how I can give this infocube parameter from report which 2 FM are called.
My code is following:

So far this creation of report is only the 2nd step.But I am not sure how step 3 to step 6 should be done so that the report can be execute exactly.
What should I do? Pleas help me!
Thanks in advance

ADF how can i execute a query with parameters when the page renders

hi
i am using ADF web 11g
i need to execute a query with parameters when the page renders
thanks

hello,
I'm a fan of Java code, I really am.
But when you use ADF, you decided to move to a more declarative environment.
So why not do it declarative, the adf way?
In your pagedef insert a action binding.
This can be anything, a call to the application module, a call on the iterator(Like executeWithparams, etc.)
Create an invokeAction in your pagedef and set the condition.
This example refreshes(Action 2 is execute query) the data.
First the method binding:
    <action IterBinding="PersoonIterator" id="Execute" InstanceName="LSAppModuleDataControl.Persoon"
            DataControl="LSAppModuleDataControl" RequiresUpdateModel="true" Action="2"/>And the invoke action
    <invokeAction Binds="Execute" id="refreshData"/>This always refreshes the data on page entry, but anything is possible, you can set condictions for the invokeAction.
-Anton
PS Yes I know that pagedefs become backing beans in the end and yes that is Java code, but if you wanna play the ADF way, the goal is the reduction of Java code and the increased performance of declarative programming.

How can I write waveform data from a while loop?

Alright, I have a NI-5122 high speed digitizer that I need to acquire 10,000 waveforms. I am currently using the NI example code "niScope EX Multi Record Fetch More Than Available Memory.vi" to do this and then onto that later. I set the Number of Records to 10,000, min record length to 8192, and the min sample rate to 100M (S/s). On the Fetch vi, I set it to get a 1D Dbl array and then send it to the while loop edge for auto indexing. What I want is to take each waveform and write it to a file next to the previous waveform not append it to the bottom of the previous one. I can do 100 and sometimes 1000 waveforms with my current setup and then use "write measurement to file.vi" to save the data, but at 10,000 it says that the memory is full. I have 256 MB on the NI-5122 and 4G of memory on my host computer. My reasoning is that if the NI-5122 can hold all that data then why can't my host computer. I have tried to fetch using 2D Dbl and transpose that matrix and send the data to "write measurement to file.vi" inside the loop and append the data that way, but when I do this the card does not acquire any data. Which seems like a software problem. I know this is probabaly worded poorly, so just post a response if further explanation is needed.
Thank you.

Hello,
It sound like you might have received a LabVIEW: Memory is full message. Are you also graphing this data as it is being acquired? Are you building an array inside the loop? At the 100 MS/s rate, you are using a lot of memory to acquire, graph, build and transpose array data, and then write to file. If you are saving to file and do not necessary need to see the data, I would suggest taking the graphical indicator out of the code. Please review some of the KnowledgeBases linked below about the LabVIEW: Memory is full.

Query with a WHILE loop

DECLARE
@databasename AS
NVARCHAR(128);
SET
@databasename =
(SELECT
MIN(name)
FROM sys.databases
WHERE
name NOT
IN    ('master',
'model',
'msdb', 'tempdb'));
WHILE
@databasename IS
NOT NULL BEGIN
PRINT @databasename;
SET @databasename
= (SELECT
MIN(name)
FROM sys.databases
       WHERE
name NOT
IN     ('master',
'model',
'msdb', 'tempdb')
       AND
name >
@databasename); END
Databases
A
B
C
D
I have question related to the above SQL statement, forgive me as I am unfamiliar with WHILE loops.
I understand that the query above finds the minimum database name, prints the value then finds the next database greater than the minimum.
What happens when it loops occurs, I know it prints the database name of the one it has found. In the example above it will be B. Will the @databasename be then set to B and the following query will be run so the @databasename will then be
set to C?
SELECT
MIN(name)
FROM sys.databases
       WHERE
name NOT
IN     ('master',
'model',
'msdb', 'tempdb')
       AND
name >
@databasename);

Yes. You run this query:
SET @databasename =
   (SELECT MIN(name)
FROM   sys.databases
WHERE name NOT IN    ('master','model', 'msdb', 'tempdb'));
This gives you the first user database, alphabetically according to your system database. The WHERE clause filters out the system databases.
Then in the WHILE loop you do the same, with one condition added:
    AND name > @databasename
So this gives the next user database alphabetically. But if there is no further database, the query returns NULL, and the condition in the WHILE statement will evaluate to FALSE, and the loop will terminate.

AI Read is executing only once in a while loop instead of continuously scanning the channels

The ultimate goal is to sample 15 channels (1 at 20kHz, 9 at 1000Hz, and 5 at 100Hz). Since only one scan rate is possible, I would like to reduce the data (for both displaying and saving purposes). The decimate function does not seem to work correctly.
Attached is the current subroutine used to 'decimate' the data. It seems to work on the first loop iteration, as seen by the data block with correct time stamps and data values, but with each additional iteration, all values are zero. Why is only one scan being used in the displaying of data?

When you call AI Clear, the DAQ session is over. You will not get any new data by calling AI Read after an AI Clear. Move your AI Clear to the right of your while loop such that it runs after the while loop completes. Don't forget to wire an error cluster or DAQ session ID to AI Clear from inside the while loop to create the data dependency. Also, consider adding a shift register for the error cluster and some way to exit the loop on an error.

Can I execute a query against an already populated RowSet object?

Hi,
Is it possible to query an already retrieved RowSet object?
Something like "search within results" feature that many search engine posses .
Thank you in advance, Kostas

There is no ready-made way to execute SQL queries against a ResultSet. Anyway, you shouldn't keep ResultSets open, you should convert them to collections of objects and close them.
When you get the ResultSet, loop over it, create an object of a suitable class from each row, and store those objects in a LinkedList.
When you need to search within the results, loop over the LinkedList and pick the objects you need.
Alternatively, re-execute the SQL query with the additional WHERE clauses appended to the original query.

FRM-40737 How can I execute a query in a post block ?

Hi,
I have two blocks based on the same table. Then it is not a 'real' master detail case. The first block contains two fields who are the values in the where clause of the second block. In which trigger or where do I place the EXECUTE-QUERY ? I can't place it in the post-block because post-block don't accept EXECUTE-QUERY and I dont want to use a timer because it bring me some troubles.
Than'k you !

I have two blocks based on the same table. Then it is not a 'real' master detail case. You can easily create a master-detail here, if your data model allows it. A table can have a foreign key relation to itself. E.g. emp.manager_id if the fk to emp.empno.
