Group by hour and get percentage of value on a particular

Hi All,
Oracle 11g
create table test_table_2 ( time_log TIMESTAMP(6), status number, names varchar2(500) );
insert into test_table_2 (time_log,status,names) values(systimestamp - INTERVAL'7'hour ,1,'FN:Will,LN:Smith');
insert into test_table_2 (time_log,status,names) values(systimestamp - INTERVAL'7'hour ,0,'FN:Will,LN:Paul');
insert into test_table_2 (time_log,status,names) values(systimestamp - INTERVAL'7'hour ,0,'FN:Will,LN:Liza');
insert into test_table_2 (time_log,status,names) values(systimestamp - INTERVAL'7'hour ,0,'FN:Will,LN:June');
insert into test_table_2 (time_log,status,names) values(systimestamp - INTERVAL'6'hour ,0,'FN:Ann,LN:Smith');
insert into test_table_2 (time_log,status,names) values(systimestamp - INTERVAL'5'hour ,0,'FN:John,LN:Blair');
insert into test_table_2 (time_log,status,names) values(systimestamp - INTERVAL'4'hour ,1,'FN:Peter,LN:Lloyd');
insert into test_table_2 (time_log,status,names) values(systimestamp - INTERVAL'3'hour ,1,'FN:Sam,LN:Smith');
insert into test_table_2 (time_log,status,names) values(systimestamp - INTERVAL'2'hour ,0,'FN:Will,LN:Smith');
insert into test_table_2 (time_log,status,names) values(systimestamp - INTERVAL'1'hour ,0,'FN:Will,LN:Smith');
In the above record I want to see the percenatge of status coulmn being 1 for a given hour.
In other words in the above table
curtime - 7 should give 25%
curtime - 6 should give 0%
curtime - 5 should give 0%
curtime - 4 should give 100%
Currently I am doing two queries
1. grouping by hour for status being 1 and
2. grouping by hour for status being 0
and then calculating the percentage on java level.
I thought it will be lot simpler if it can be done in one shot in sql itself.
Appreciate your help with this.

Well, i wasn't sure what happened to curtime - 3, curtime -2 and curtime -1 ... but maybe this is a start for you.
create table test_table_2 ( time_log TIMESTAMP(6), status number, names varchar2(30) );
declare
l_timestamp timestamp := systimestamp;
begin
insert into test_table_2 (time_log,status,names) values(l_timestamp - INTERVAL'7'hour ,1,'FN:Will,LN:Smith');
insert into test_table_2 (time_log,status,names) values(l_timestamp - INTERVAL'7'hour ,0,'FN:Will,LN:Paul');
insert into test_table_2 (time_log,status,names) values(l_timestamp - INTERVAL'7'hour ,0,'FN:Will,LN:Liza');
insert into test_table_2 (time_log,status,names) values(l_timestamp - INTERVAL'7'hour ,0,'FN:Will,LN:June');
insert into test_table_2 (time_log,status,names) values(l_timestamp - INTERVAL'6'hour ,0,'FN:Ann,LN:Smith');
insert into test_table_2 (time_log,status,names) values(l_timestamp - INTERVAL'5'hour ,0,'FN:John,LN:Blair');
insert into test_table_2 (time_log,status,names) values(l_timestamp - INTERVAL'4'hour ,1,'FN:Peter,LN:Lloyd');
insert into test_table_2 (time_log,status,names) values(l_timestamp - INTERVAL'3'hour ,1,'FN:Sam,LN:Smith');
insert into test_table_2 (time_log,status,names) values(l_timestamp - INTERVAL'2'hour ,0,'FN:Will,LN:Smith');
insert into test_table_2 (time_log,status,names) values(l_timestamp - INTERVAL'1'hour ,0,'FN:Will,LN:Smith');
end;

time_log,
count(case when status = 1 then 1 else null end) / count(*) * 100

How to find colums in CLOB variable and get this colums value to update col

Question
How to find colums in CLOB variable and get this colums value to update colum of oracle database table
How my work will go
Step-1 - I am creating XML FIle which is based on code that we discused before-
Its developing xml file with data in <...inputelement> as u can see in my xml but in <..output> Element of xml its just have all column for exampe <itemoutput>
<FLD NM = "ABC"> 0 </FLD>
<FLD NM = "XYZ:> </FLD> --- for varchar2
</itemoutput>
In 1st stage i am just generating <..INPUT> with its colums and real value from database and <..output> elements will go zero value but with colums name.
Note. I create temp table will all COLUMN which u can see in both in <..ITEMINPUT> and <..ITEMOUTPUT>
Step2.. After Generaing my xml i want to convert my xml data into CLOB not in a file. so clob will go to the VENDOR
STEP3.
I will Recieved again xml data in CLOB from the vendo in <.OUTPUT> ELEMents
for example
I send this format
<itemoutput>
<FLD NM = "ABC"> 0 </FLD>
<FLD NM = "XYZ:> </FLD> --- for varchar2
</itemoutput>
And i will receive it
<itemoutput>
<FLD NM = "ABC VALUE"> 2 </FLD>
<FLD NM = "XYZ TYPE:> SUV</FLD> --- for varchar2
</itemoutput>
So will take this output valu from xml clob and will update my staging table .
Which have the same colum name as its look in xml clob.
Step- 4. I will take this value from staging table and update my original oracle database table. which i send you before.
But u leave this step becaue you dont know the staging table colum maping with original table.
I think now you understand
Please feed back
monriz

here is my xml..
I want to extract <..output> elements which enclosed with " " and its values from this xml file. please any body have any idea. please tell me
Thanks

How to call an Oracle Procedure and get a return value in Php

Hi Everyone,
Has anyone tried calling an Oracle procedure from Php using the ora functions and getting the return value ? I need to use the ora funtions (no oci)because of compatibility and oracle 7.x as the database.
The reason why I post this here is because the ora_exec funtion is returning FALSE but the error code displayes is good. Is this a bug in the ora_exec funtion ?
My code after the connection call is as follows:
$cur = ora_open($this->conn);
ora_commitoff($this->conn);
$requestid = '144937';
echo $requestid;
$rc = ora_parse($cur, "begin p_ins_gsdata2
(:requestid, :returnval); end;");
if ($rc == true) {
echo " Parse was successful ";
$rc2 = ora_bind ($cur, "requestid", ":requestid", 32, 1);
if ($rc2 == true) echo " Requestid Bind Successful ";
$rc3 = ora_bind ($cur, "returnval", ":returnval", 32, 2);
if ($rc3 == true) echo " Returnval Bind Successful ";
$returnval = "0";
$rc4 = ora_exec($cur);
echo " Result = ".$returnval." ";
if ($rc4 == false) {
echo " Exec Returned FALSE ";
echo " Error = ".ora_error($cur);
echo " ";
echo "ErrorCode = ".ora_errorcode($cur);
echo "Error Executing";
ora_close ($cur);
The Oracle procedure has a select count from a table and it returns the number of records in that table. It's defined as:
CREATE OR REPLACE procedure p_ins_gsdata2 (
p_requestid IN varchar2 default null,
p_retcode OUT varchar2)
as
BEGIN
SELECT COUNT (*) INTO p_retcode
FROM S_GSMRY_DATA_SURVEY
WHERE request_id = p_requestid ;
COMMIT;
RETURN;
END;
Nothing much there. I want to do an insert into a table,
from the procedure later, but I figured that I start with a select count since it's simpler.
When I ran the Php code, I get the following:
144937
Parse was successful
Requestid Bind Successful
Returnval Bind Successful
Result = 0
Exec Returned FALSE
Error = ORA-00000: normal, successful completion -- while
processing OCI function OBNDRA
ErrorCode = 0
Error Executing
I listed the messages on separate lines for clarity. I don't understand why it parses and binds o.k. but the exec returns false.
Thanks again in advance for your help. Have a great day.
Regards,
Rudi

retcode=`echo $?`is a bit convoluted. Just use:
retcode=$?I see no EOF line terminating your input. Your flavour of Unix might not like that - it might ignore the command, though I'd be surprised (AIX doesn't).
replace the EXEC line with :
select 'hello' from dual;
and see if you get some output - then you know if sqlplus commands are being called from your script. You didn't mentioned whether you see the banner for sqlplus. Copy/paste the output that you get, it will give us much more of an idea.

Call a webservice and get back a value within an ESB...

Hi!
I'd like to call a webservice and get back a value from it within an ESB. But I don't know how.
I think, I must create a routing service, then a SOAP service, but how can I get back the value from the webservice, which I called in the SOAP service?
Or it is not possible to realize this within an ESB?
Thank You very much!
Viktor

When you take a look at the Soa Orderbooking example you can see how it works. You create a webservice that accepts certain parameters and these are bundled into an object. This object, in case of the Soa Orderbooking example a 'PurchaseOrder', is described using an Xml Schema. The XML Schema is used to create the ESB with. Using this xsd the ESB knows which object it can expect and this object can be used inside your ESB or inside a bpel process.

How can I get the default value of a particular preference in FireFox?.
I know I can see the default value for some of the preferences in about:config but, I need a programatic way to get the default value.
I see some that there are values for preferences in firefox.cs but I am not certain that these are being used as the default values for preferences. prefs.js in user's profile only has the updated values and not the default values.
Any help towards acheiving this programtically is greatly appreciated.
If the default values are stored in a file, kindly let me know the format in which it is stored for me to parse it programatically.

Dear Friend,
Here when you have the callableSattement as ?=proc(?), the first ? is an output parameter. So you should register it as out parameter using registeroutparameter.
Then you can get the value from the outparameter using callablestatement.getXXX().
Try that way.

Multiply a sum of durations and get a dollar value....

So I'm adding 5 duations(work hours in the week), no problem there.
I have my total hours in a cell, now I want to multiply that duration by a number(pay rate) and get a dollar amount. Can't figure it out.....?
Any help?

=SUM($D3,$G3,$J3,$M3,$P3)
This is what is in the cell, if I multiply by 5(*5) I get 62h 30 minutes.
How can I change that duration to a dollar value? ($62.50)

How to set the value of an LOV in CO prgramatically and get the Pkey value?

Hi,
I need to set a value to a LOV, say ItemLOV in a page through CO and get the Primaykey that LOV will return. How can I achieve this?
Req:
1. Set the Item_Name, say 'DELL_1618' so that the page displays this in the LOV.
2. Fetch the PK value returned by LOV in the backend into a VO attribute say Item_ID, '100009881'.
Thanks,
Santosh.

Hi Santosh,
Sorry, I replied for General LOV Scenario, but want to set it programatically right,
You need to execute your LOV query in Controller for Item 'DELL_1618' using prepared statement, get the value for both dispaly value and Id and set it to LOV and FormVlaue Item in PR of controller.

VB Script to accept PC names in text file and get registry key value out of those systems

Hi All,
My task: Create VB script to accept PC names from a text file, process each host name to get Registry key value of individual host name and finally export them to a text file or an excel sheet having registry key value against each pc.
I want to pull key value of LSFORCEHOST located in HKCU/Environment of each PC and export this value against each pc in a text or Excel file.
What I achieved: I am able to process against single pc name but failed to process 3000+ systems listed in a text file which I tried to process through VB script. I am not pro and learning the VBS and cant write complex code.
My VBS code written so far(It failed many time with issue):
Option Explicit
Const HKEY_CURRENT_USER = &H80000001
Dim oFSO, sFile, oFile, sText, strComputer,oReg, strKeyPath, strValueName, strValue, objFSO, objFile, strContents
Set oFSO = CreateObject("Scripting.FileSystemObject")
sFile = "test.txt"
If oFSO.FileExists(sFile) Then
Set oFile = oFSO.OpenTextFile(sFile, 1)
Do While Not oFile.AtEndOfStream
sText = oFile.ReadLine
If Trim(sText) <> "" Then
strComputer = sText
Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & _
strComputer & "\root\default:StdRegProv")
strKeyPath = "Environment"
strValueName = "LSFORCEHOST"
oReg.GetStringValue HKEY_CURRENT_USER,strKeyPath,strValueName,strValue
Const ForReading = 1
Const ForWriting = 2
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("C:\destination.txt",1, ForReading)
strContents = strValue
Set objFile = objFSO.OpenTextFile("C:\destination.txt",2, ForWriting)
objFile.Write strContents
objFile.Close
End If
Loop
oFile.Close
End If
I think when I tried to process each PC name from text file against registry key value, above code not working. As per my knowledge some issue in loop. Do I need to add FOR EACH feature?
Please help to correct it. Thanks in advance.

Your code contains numerous errors. Furthermore you make things difficult for yourself by giving similar names to the objects used for your input and output. If you are a systems administrator then your best bet is to make an effort to learn the language
instead of grabbing a few code fragments from here and there and hoping that somehow they will work.
Try the cleaned up code below for this particular project. Note the consistent code indentation. It helps you enormously when trying to understand the structure of the code. Remember also that you must fully qualify all file paths. Writing to "Destination.txt"
will cause endless confusion because you never know for sure where this file will reside.
Const HKEY_CURRENT_USER = &H80000001
Set oFSO = CreateObject("Scripting.FileSystemObject")
sKeyPath = "Environment"
sValueName = "LSFORCEHOST"
sFile = "D:\Test.txt"
If oFSO.FileExists(sFile) Then
Set oInput = oFSO.OpenTextFile(sFile, 1)
Do While Not oInput.AtEndOfStream
sComputer = oInput.ReadLine
If Trim(sComputer) <> "" Then
Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" _
& sComputer & "\root\default:StdRegProv")
oReg.GetStringValue HKEY_CURRENT_USER,sKeyPath,sValueName,sValue
Set oOutput = oFSO.OpenTextFile("D:\destination.txt",8, True)
oOutput.WriteLine sValue
oOutput.Close
End If
Loop
oInput.Close
End If

Run query and get unexpected node values

Hi,
I am not seeing what should be expected when I run my query, and I am getting the display of the hierarchy nodes that I am not supposed to get access to. I checked my profile and I have the 0COSTCENTER as '*' and TCTAUTHH as ':' .
Where should I start finding why I am getting the node values displayed that I am not supposed to?
Thanks
Will

Welcome to SDN.
I think you should better post it to the BI forum.
Did you try to use the user exit EXIT_SAPLRRS0_001 (extension RSR00001) to initialize the values? And for bypassing the selection screen, can't you define it in the query definition (if I remember well)?

Present a dialog screen to the user that always stays open and gets updated with values from teststand.

Hello,
I'm new to TestStand and just created my first sequences with TS and LV.
The program is running fine but now I need to implemented a dialog screen with some progress results for the user.
This dialog screen must stay open (unless closed by the user) and gets refreshed with the latest analysis results from TestStand.
Is there an example of something like that. (starting from a working example is always easier)
So I need a mechanism to give some results from TestStand to a custom made dialog screen in LabVIEW.
Any thoughts/examples/recommandations ???
Thanks!

Hi noxus,
The basic design you are looking for is a daemon, This is basically a VI that runs in the background (your dialog VI for example). This VI is launched dynamicly when needed. And there should be a way of detecting if the deamon is running.
You can use various ways of communicating between VI's. The two most use full I find either Queues or TCP. The added bonus for TCP is that it also works over the Network, but could also be slower and blocked by Firewalls. Queues only work within the LabVIEW Process running on the Local machine and provide a nice way of detecting if the daemon VI is running.
Attached a example that show how you can implement something like this. The 'sent new value.vi' obtains a queue reference, we check if it has created a new queue or if it returned an existing queue reference. If the obtain queue created a new queue this means the daemon is not running and we launch the deamon.vi.
The daemon also connects to the same queue and maintains the reference. If the deamon is closed the referenced is closed as well and the queue is destroyed.
You can run the example VI. (in LabVIEW 8.2).
Hope this helps.
Thanks
Karsten

Group by GEOM and get unique points

Hello,
I need some help with a spatial query. I have a table of addresses and wanted to know if there is an easy way to group by x and y coordinates , so that I just get one record for multiple addresses with the same coords (and do simple clustering).
This is my current sql statement
select map_id, m.shape.sdo_point.x as X, m.shape.sdo_point.y
from MAPS m
where MDSYS.SDO_RELATE (m.SHAPE,
MDSYS.SDO_GEOMETRY(2003,
8311,
NULL,
MDSYS.SDO_ELEM_INFO_ARRAY(1, 1003, 3),
MDSYS.SDO_ORDINATE_ARRAY(<%= mbrCoords[3]%>, <%= mbrCoords[2]%>, <%= mbrCoords[1]%>, <%= mbrCoords[0]%>)), 'mask=ANYINTERACT') = 'TRUE';

Hi,
another way would be like this (geom is SDO_GEOMETRY)
-- 2D
select A.* from
       select t.id, gv.x,gv.y
       from <TABLE> t, table(sdo_util.getvertices(t.geom)) gv
       ) A, (
       select count (gv.x||gv.y) ct , gv.x,gv.y
       from <TABLE>, table(sdo_util.getvertices(geom)) gv
       group by gv.x,gv.y
       ) B
where A.X = B.X and A.Y = B.Y
and B.ct > 1
-- 3D
select A.* from
       select t.id, gv.x,gv.y ,gv.z
       from <TABLE> t, table(sdo_util.getvertices(t.geom)) gv
       ) A, (
       select count (gv.x||gv.y||gv.z) ct , gv.x,gv.y,gv.z
       from <TABLE>, table(sdo_util.getvertices(geom)) gv
       group by gv.x,gv.y,gv.z
       ) B
where A.X = B.X and A.Y = B.Y and A.Z = B.Z
and B.ct > 1

How to sample an analog signal, simulated on labview and get the sample values.

My project involves this particular detail where i have to sample a simulated sine wave and get the samples and compare them so as to select a particular length for hanning window.Then it also requires me to experiment with the window size so as to get more efficient data out of the sampled signals. please help me with the sampling part and guide me as to how to perform a hanning window operation on the sampled signal. I have directly used the spectral analysis tool which involves getting a FFT spectrum by a default hanning window setting. But since i have to experiment with the window size and variations, guide me with the sampling part and applying a separate hanning window. Thank you.

What do you mean by i have to sample a simulated sine wave?
the sine generator will provide you with a waveform (or an array of values you can use), there are basic vis to do all this, rigth click on the vi and select help to get detailed information.
Post your vi if you have trouble with details.

How to pass a value to a BC4J method from JSP/ADF and get a return value.

How i can access and application module method from my jsp using JSTL passing a value and hope a return value from BC4J method already exposed using interfase and droped from data control to my jsp page
Any suggestions ?

Hi,
Check the size of that Window in which you are displaying this Text of 130 characters.
May be it is less
in that case split that string into 2 strings and pass the two strings from ITCSY structure to script and use.
reward if useful

Inserting sequence value from JDBC and getting the same value back

Hi: Gurus I have a table whose primary key is a sequence. I wonder how to make sure I get the same sequence value back for current transaction so I update the other table whose foreign key is the sequence value from first table.
E.g lets say I do this
String query_insert = INSERT INTO table1 (column1, ....) VALUES (HIGHLIGHT_ID_SEQ.nextval, ...);
pstmt = con.prepareStatement(query_insert);
pstmt.executeUpdate();
How I make sure no other transaction update the sequence value so I can read the last inserted sequence value and update the second table with this value
String query_select = "SELECT HIGHLIGHT_ID_SEQ.currval FROM DUAL";
pstmt = con.prepareStatement(query_select);
Regards,
Rashid.

<rant>No version again. I wonder why people requiring help want to stay anonymous and never want to type their version, only 4 digits. In this case, jdbc, not only the version of the driver is important, but also it's type. Waving a magic wand again? </rant>
Look up the returning into clause of the insert statement in the sql reference manual for your version.

Executing unix script within java and getting the return value

Hi
I am executing a unix script from within java which will return me a value. Is there a way I get this value and use it inside my java code without doing this:
BufferedReader in = new BufferedReader( new InputStreamReader( ls_proc.getInputStream() ));
//readLine reads in one line of text
int k = 1, i = 0;
while (( ls_str = in.readLine()) != null)
--kirk123

I was hoping to get what I want in one or two line codes.
