CallableStatement, how to get function result ?

Hello all,
I know that this issue more relevant to JDBC, but it seems that their forum is more "sleepy" than that one therefor i trying my luck here with you...
I've a pl/sql function which get 2 int arguments, and return float result
I use CallableStatement in order to execute pl/sql function.
with CallableStatement.setInt i transfer argument to the function,
but i dont know how to "catch" function result (as i said earlier, function results is float)
any help here...
Thanks

[http://java.sun.com/javase/6/docs/api/java/sql/CallableStatement.html]
that's exactly what i did, but my teacher assistant told me that it's wrong, because CallableStatement uses for stored Procedures, but I have here a function (because it returns a value...) therefor i need to use PrepareStatment/Statement...Third person accounts are always hard to judge, but what you are claiming is wrong (whether the TA said it or not.)
First a prepared statement can in fact be used to run either a proc or function. So can statement for that matter.
However callable statement is provided as a convenience to run procs and functions.
There can however be reasons why a driver doesn't allow that - I have used a driver that didn't support callable statements at all (procs or functions.)
That said the the format I gave you is specifically modeled for functions.

Try doing this in your sql scripts

set feedback off

spool output.txt
select * from dual (or whatever you are querying

How can i do with labview program,when i have 20 different values,and 1 want to add it with constant value.and how to get the results?

how can i do with labview program,when i have 20 different values,and 1 want to add it with constant value.and how to get the results?

Why do the 20 values have to be different? The same code should work even if some are equal.
What do you mean by "get the result"? The result is available at the output terminal and all you need is a wire to get it where you need it. That could be an indicator, another operation, or even a hardware device.
What is the data type of the 20 values? An array? A cluster? A bunch of scalars? A waveform? Dynamic data?

How to get the results in one line

Hi
if i use the script below i get the name of path and then : and in next line i get the results.is there a way to get the results from every path after the : and not in the next line?
another question - is there a way that the script will not show the server name on every path?
(Get-Counter -ListSet LogicalDisk).PathsWithInstances | Get-Counter
THC

If you take you script and pipe it to get member, it will give you a list of various script properties.
(Get-Counter -ListSet LogicalDisk).PathsWithInstances | Get-Counter | get-member
You will see that the object type returned by "Get-Counter" is Microsoft.PowerShell.Commands.GetCounter.PerformanceCounterSampleSet.
TypeName:
Microsoft.PowerShell.Commands.GetCounter.PerformanceCounterSampleSet
Name MemberType Definition
Equals Method bool Equals(System.Object obj)
GetHashCode Method int GetHashCode()
GetType Method type GetType()
ToString Method string ToString()
CounterSamples Property Microsoft.PowerShell.Commands.GetCounter.Perfo...
Timestamp Property datetime Timestamp {get;set;}
Readings ScriptProperty System.Object Readings {get=$strPaths = ""...
You can try grabbing different properties, and they will print out differently, displaying the data on the same line in some cases. For example, pipe your output to a "foreach-object" block, and then for each object print out the CounterSamples property.
(Get-Counter -ListSet LogicalDisk).PathsWithInstances | Get-Counter | foreach-object { ($_).CounterSamples }
This should all print on one line now. However, you also asked if there was a way to not have the server print out on every line. The way to control the format of these outputs is to use the "format-table" cmdlet. So you would pipe your output to format-table
and then give it various options. This is how you would pipe it (without any options).
(Get-Counter -ListSet LogicalDisk).PathsWithInstances |
Get-Counter | object { ($_).CounterSamples | format-table }#OR USE YOUR ORIGINAL CODE(Get-Counter -ListSet LogicalDisk).PathsWithInstances |
Get-Counter | format-table }
Now, it's up to you to give format-table the options you want. With no options, output will look unchanged. To see what options are available to you, use get-help.
get-help format-table
I hope this helps!
Thank for all the info...

How to get webservice result as "e4x" format in a professional solution?

Hi. I want to get data from a .Net webservice as "e4x"
format. It works when i use <mx notation to define the service
in flex. However i want to build a more professional solution and
want to implement the webservice as a class. But I can't get it to
work such that i return the result as "e4x". Instead i get an
object with arrays etc. The problems might be that i need to use
the flex class operation to define "e4x" and then i need to bind
the operation with the webservice but it seems that the webservice
still doesn't know about to return the result as e4x. Here you see
the code in <mx notation which is working fine:
<mx:WebService id="WS" wsdl="
http://localhost/testservice/service.asmx?WSDL"
result="WS_onResult(event)" >
<mx:operation name="HelloWorld" resultFormat="e4x" >
<mx:request></mx:request>
</mx:operation>
</mx:WebService>
And in the WS_onResult procedure i get the result by doing
this:
var xmlResult:XML = XML(event.result);
As i said the above code is working fine but the code below
doesn't work well because it doesn't return the result as "e4x":
WS = new mx.rpc.soap.WebService();
WS.wsdl = "
http://localhost/testservice/service.asmx?WSDL";
WS.addEventListener(LoadEvent.LOAD, load_listener);
WS.addEventListener(ResultEvent.RESULT, result_listener);
OP = new mx.rpc.soap.Operation(WS,"HelloWorld");
WS.loadWSDL();
And in the load procedure to perform the call:
public function load_listener(event:LoadEvent):void {
OP.resultFormat = "e4x";
WS.HelloWorld.send();
And in the result listener i get a result as object and NOT
as "e4x". Can anyone help?
Btw. here i add the .Net code:
[WebMethod]
public XmlElement HelloWorld() {
XmlDocument doc = new XmlDocument();
string xml = "<Test>this is a test</Test>";
doc.LoadXml(xml);
return doc.DocumentElement;
}

Hmm, try setting the resultFormat at the WS level. But what
you have looks like it should work.

DbGetQuery = How to get the results to display?

I am using the following

How do I get the result to display?
summary(sqldata) displays the values
if I do dbSendQuery then fetch show the results
help(dbSendQuery) and help(dbGetQuery) go to the same page! dbSendQuery
The documentation says dbGetQuery will connect, get the records and clear; maybe the clear happens before the display?!

Hello Amin,
Here is the way to display the result from the query you provided:
Assign the result of the query to object 'sqldata':
R> sqldata <- dbGetQuery(con," select sysdate from dual")
Type the object name at the R prompt:

M-Audio Fast Track, how to get best results?

Hey guys.
I just got my M-Audio Fast Track. It seems quite cool. Not really to sure what to do with it though!
I'm using it to record guitars and vocals into GB.
So how can i set it up to get best results?
Right now I have my Audio System Preferences set to Built in Audio for In and Out, but in GB preferences I have Input set to FastTrack and Out set to Built-In...
It seems to be quite quiet, quieter than if i plug my guitar directly into the iMacs line in...?
Cheers
jim
P.S. Please don't bother writing about how I should have bought a Firewire device or anything else, I'm a cheap *** student, I bought what I could!

Jim
I have just bought one and the sound is good. I monitor sound thru my HI_FI system. The settings I have are:
1. Leave sound settings alone in system preferences.
2. In GB2 I have set input and output devices to fast track. (By the way there are no drivers available for this device - it is natively supported by OS X)
To adjust volume I have to adjust the right hand output volume knob on the front of the Fast track. My G5 system volume control has no effect on the fast track.

How to get two Results - Sum and Average for one KeyFigure

I have "Material" in Rows and "Cal Year/Month" in Columns and also KeyFigure "Qty" in Columns.
The Results (Yellow) of "Qty" is defined as "Avg of all values <>0". This works fine but how do I get two Results - one is a "Sum" and the other "Avg" for just one KeyFigure. The output basically should look like below:
      Cal Yr/Month 01/2006   02/2006   03/2006...    Result        Result
Material                   Qty       Qty           Qty       Sum of Qty   Avg of Qty
ABC                       100         0             200            300             150
DEF                       100         200          300            600             200
GHI                        500         300          400           1200            400

Hi Srinivas,
I think you must use Restricted Key Figures and Formula.
Do not introduce CALMONTH in columns, but restrict 12 times the Key Figure Qty with 0CALMONTH3, that is 01-02-03-...
Then create a Formula that is the Sum of all Restricted KF and call it SUM.
Then copy the previous Formula (SUM) and call it AVG and give the option of Average of all Values <>0.
Try.
Ciao.
Riccardo.

How to get Test Results to SQL w/o Coldfusion

Is there a way to get Captivate test results (or any results)
to SQL. I was thinking of using the SCORM interface?
A simple elegant solution would be great since I want to
build it into to all my componants.
Thanks in advance,
Scott

If your organization is running Sharpoint 3.x, you can use
the sharepoint learning kit which runs off of a sql back end. This
is a SCORM 2004 compliant LMS that can be found here:
http://www.codeplex.com/SLK
If you want to do this without an LMS, you can set up your
quiz to just send the score as in this article:
http://www.adobe.com/devnet/captivate/articles/store_cpresults_print.html
You steal the idea from here, but in your javascript, you can
do a pass your variables (quiz resutls), to an asp.net page that
places them into a SQL db. I'm working on such a solution right
now. That way, you don't need an LMS and you have complete control
over how and when the results are stored.

How to get accurate results from sql code ?

Hello everybody,
I have a problem with some portion of my code.
I get more results than I specify in the where clause.
Here is the sample code:
c.gl_acct_id between '110'||'-'||'6890'||'-'||'69000'||'-'||'%'
and '110'||'-'||'7000'||'-'||'67999'||'-'||'%'
For some reason I also get the following results back:
110-6910-51001-001, and 110-6910-51003-001 But I don't need the 51001 and 51003. How do I specify in sql what range I really want. I was sure that the code above is correct. I guess not.
I would appreciate any help,
Thanks,
Sonya

Have you tried using the query either of the following...
1) c.gl_acct_id between '110-6890-69000-000'
and '110-7000-67999-999'
and c.gl_acct_id not like '110-6910-51001-%'
and c.gl_acct_id not like '110-6910-51003-%'
assuming you have only 3 digits at the end of gl_acct.
2)If you know that your acct_id belongs to only 69000 or 67999
then
(c.gl_acct_id LIKE '110-6890-69000-%' OR
c.gl_acct_id LIKE '110-7000-67999-%' )
Plz. let me know if this not what you are looking for.
thanx
rajkiran
Here is the whole script:
select distinct c.gl_acct_id acct_no,
c.gl_acct_desc,
min(a.local_act_beg_bal) local_act_beg_bal,
sum(b.local_act_mtd_dr_amt) debits,
sum(b.local_act_mtd_cr_amt) credits,
nvl(min(a.local_act_beg_bal),0)+sum(nvl(b.local_act_mtd_dr_amt,0))-
sum(nvl(b.local_act_mtd_cr_amt,0)) end_bal
from gl_acct c, gl_acct_bal a, gl_acct_bal b
where c.org_unit_id = '110'
and b.gl_acct_id = c.gl_acct_id
and a.gl_acct_id = c.gl_acct_id
and c.sum_det_ind = 'D'
and c.gl_acct_class_ind in ( 'A' , 'L' , 'Q' , 'I' , 'E' )
and a.year_no = '2001'--:loyear
and a.period_no = '1'--:loperiod
and ( ( b.year_no = '2001'--:hiyear
and b.period_no between '1'--:loperiod
and'13')-- :hiperiod
and c.gl_acct_id between '110'||'-'||'6890'||'-'||'69000'||'-'||'%'
and '110'||'-'||'7000'||'-'||'67999'||'-'||'%'
group by c.gl_acct_id, c.gl_acct_desc
I want to have ability to specify ranges for gl_accoount.
Thanks,
Sonya
