Extract x value
in a continuous stripchart, how can I extract the x value to use as a comparator value for a programmatic function at a specific point in time
If you mean Waveform Chart, you can't exactly extract an x value. The Waveform Chart plots y data on equispaced x points, so the x value is really just point number. If your plotting is in a loop, just monitor the iteration indicator (usually in the lower left).

Extracting all values from multiple menus
Hello all,
Basically I have a jsp that consists of three of what FrontPage calls drop down boxes but I will hereafter call list boxes, each containing a number of options extracted from a database; these values can be moved from one box to another using java script. When I hit a submit button I wish to be able to extract all the values from two of these lists and add them into a database. I know how to extract selected values but I need all the values of both lists regardless of what the user selects and I need the contents of each kept distinct.
Any help provided will be appreciated and I apologize if this question is something all the forum vets have already seen before.
PhilipOnly the values that are selected will be submitted
with the form. So, add a call to your form tag's
onSubmit event to call a function like this:<form name='myForm' onsubmit='selectAll()'>
<script language='javascript'>
function selectAll() {
for(i=0; i<myForm.mySelectList.options.length; i++)
myForm.mySelectList.options.selected = true;
// do the same for the other two select lists
</script>
Thanks for the tip, but unfortunately this means that the two list boxes that I want will become intermingled. Is there a way to keep the information in the two lists seperate?

How to extract the values from WPBP table
Hi experts,
We are in preparation of a custom report.
In the report we want to have a value from WPBP table.
We want to extract the value of Capacity utilization level from WPBP table.
Could you please let me know the way to extract the value.
Please advice.
Regards,
Sairam.Hi Sairam,
Why do you try to get capacity utilization level from WBPB. Even if there is split in payroll capacity utilizatian level in WPBP shows the value in IT0008 basic pay.
So instead you can get the required information from table PA0008 Field for capacity utilization level is BSGRD

NullPointerException was thrown while extracting a value from an instance
Dear all,
We have got a null point exception during commit call. According to the stack trace shown below, it seems that it is a problem due to instance variable accessor. As we know toplink use reflection to access the instance variable value. I am curious whether the exception we got is related to any class-loader setting. Thanks a lot.

Can anybody tell me how to extract sales value and cost value for an materi
dear all,
Can anybody tell me how to extract sales value and cost value for an material sold .
All the values of cost value and sale values are getting stored in bseg-wrbtr field .
How to identify them uniquely.
Or there is another way to find the sale and cost values.
Regards
MaveHi Mave!
Normally there is no condition change, when something is sold.
But sales price depends on sales conditions (not only price, but also surcharges, discounts, taxes - if customized).
Nevertheless, after selling you have a invoice document, where correct values <i>should</i> be stored (see VBRP fields mentioned above). If here is a problem, then customizing of price determination is in question, not a programming of user-exits with MARD selection for costs (or some other tries to get a price).
When you specify your requirements more in detail, you might get better answers - but currently only general hints are possible ('see in invioce / G/L accounts').

Failing to extract xml value using Jdom & Xpath
I have a method (getSingleNodeValue()) which when passed an xpatch expression will extract the value of the specified element in the xml document refered to in 'doc'. Assume doc at this point has been initialised as shown below and xmlInput is the buffer containing the xml content.
SAXBuilder builder = null;
Document doc = null;
XPath xpathInstance = null;
doc = builder.build(new StringReader(xmlInput));When i call the method, i pass the following xpath xpression
/TOP4A/PERLODSUMDEC/TINPLD1/text()Here is the method. It basically just takes an xml buffer and uses xpath to extract the value:
public static String getSingleNodeValue(String xpathExpr) throws Exception{
Text list = null;
try {
xpathInstance = XPath.newInstance(xpathExpr);
list = (Text) xpathInstance.selectSingleNode(doc);
} catch (JDOMException e) {
throw new Exception(e);
}catch (Exception e){
throw new Exception(e);
return list==null ? "?" : list.getText();
}The above method always returns "?" i.e. nothing is found so 'list' is null.
The xml document it looks at is
<TOP4A xmlns="http://www.testurl.co.uk/enment/gqr/3232/1">
<HEAD>
<Doc>ABCDUK1234</Doc>
</HEAD>
<PERLODSUMDEC>
<TINPLD1>10109000000000000</TINPLD1>
</PERLODSUMDEC>
</TOP4A>The same method works with other xml documents so i am not sure what is special about this one. There is no exception so the xml is valid xml. Its just that the method always sets 'list' to null. Any ideas?
Edit
Here is a running program testing the above:
import org.jdom.*;
import org.jdom.input.*;
import org.jdom.xpath.*;
import java.io.IOException;
import java.io.StringReader;
public class XpathTest {
public static String getSingleNodeValue(String xpathExpr, String xmlInput) throws Exception{

SAXBuilder builder = null;
Document doc = null;
XPath xpathInstance = null;
try {
builder = new SAXBuilder();
doc = builder.build(new StringReader(xmlInput));
xpathInstance = XPath.newInstance(xpathExpr);
list = (Text) xpathInstance.selectSingleNode(doc);
} catch (JDOMException e) {
throw new Exception(e);
}catch (Exception e){
throw new Exception(e);
return list==null ? "Nothing Found" : list.getText();
public static void main(String[] args){
String xmlInput1 = "<TOP4A xmlns=\"http://www.testurl.co.uk/enment/gqr/3232/1\"><HEAD><Doc>ABCDUK1234</Doc></HEAD><PERLODSUMDEC><TINPLD1>10109000000000000</TINPLD1></PERLODSUMDEC></TOP4A>";
String xpathExpr = "/TOP4A/PERLODSUMDEC/TINPLD1/text()";
XpathTest xp = new XpathTest();
try {
System.out.println(xp.getSingleNodeValue(xpathExpr, xmlInput1));
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}When i run the above, the output is
Nothing foundEdit
I have run some further testing and it appears that if i remove the namespace url it does work. Not sure why yet. Is there any way i can tell it to ignore the namespace?

It works fine, the problem is not with namespace, it is with url have given.

Found a way to say the program to ignore namespace.
You have to use Xpath.addNamespace(prefix,uri), and pass the prefix to your pattern string.
If not clear refer the below code:

Using WQL "one-liner" to extract a value from the registry
Can I extract a value from the registry using a "one-liner" WQL command? Something like the following:
Under root\default:StdRegProv
SELECT <Data> FROM "HKLM:SOFTWARE\Toto\Version"
Please note that I am aware of how this is done via script. The problem is that I'm using a management system (SCOM), which only allows me to supply a simple WQL query to perform my evaluation.
Thanks,

Extract Node Values using XPATH
This may be a repeat question.
No offence meant
I am using XPATH to extract values from the nodes.
I need to extract the value of i:RequestedBy Node using XPATH
<?xml version="1.0" encoding="UTF-8"?>
<i:Interest>
<i:Status>0</i:Status>
<i:Generation>2</i:Generation>
<i:Details xsi:type="i:vanilla.details.stock">
<i:RequestedBy>AA.MM</i:RequestedBy>
The above XML is of type Document
Document msgDoc;
XPath xpath = XPathFactory.newInstance().newXPath();
XPathExpression expr;
Object result=null;
try {
expr = xpath.compile("i:Interest/i:Details/i:RequestedBy/text()");
result = expr.evaluate(msgDoc, XPathConstants.NODESET);
NodeList nodes = (NodeList) result;
for (int i = 0; i < nodes.getLength(); i++) {
System.out.println(nodes.item(i).getNodeValue());
} catch (XPathExpressionException e1) {
e1.printStackTrace();
I am getting null/
Is my XPATH correct?I don't know if your XPath is correct or not. Your XML is not well-formed because the namespace declarations are missing. And I don't see where you set the namespace context for your XPath object; that is quite likely why it doesn't do what you want.

Best way to extract XML value wiith an xpath
Hello,
I wonder what is the best way to extract text value from XmlType with an xpath.
I need to insert a row inside a table where the row's data come from xpath extractions of an XmlType. I do a lot of (approximative 20) :
EXTRACTVALUE(var.myxmltype , '/an/xpath/to/extract/elem1').
EXTRACTVALUE(var.myxmltype , '/an/xpath/to/extract/elemI').
EXTRACTVALUE(var.myxmltype , '/an/xpath/to/extract/elem20').
inside the insert statement
Is this way is the best or is there a more optimal way ?
For example extracting the node '/an/xpath/to/extract/' and sarting from this node extracting "elem1", ... , "elemI", "elemN" children.
Thanks for your help,
Regards,
NicolasHi Nicolas,
The answer depends on your actual storage method (binary, OR, CLOB?), and db version.
You can try XMLTable, it might be better in this case :
SELECT x.elem1, x.elem2, ... , x.elem20
FROM your_table t
, XMLTable(
'/an/xpath/to/extract'
passing t.myxmltype
columns elem1 varchar2(30) path 'elem1'
, elem2 varchar2(30) path 'elem2'
, elem20 varchar2(30) path 'elem20'
) x

Extract element value from a trigger

Thanks in advanced.ExtractValue is a SQL Function not a method
You'll need something along the lines of
select extractValue(:new.sys_nc_rowinfo$,'/PurchaseOrder/Reference')

Extract two values (date) on minutes
I want to extract two values, that are both from the DATE datatype, to see if there are more than 5 minutes between the two values. How can I do that? When i extract two of those values, it works with days, not minutes. I can devide by 1440 (24 * 60), but that won;t work.
Help please!I can devide by 1440 (24 * 60), but that won;t work.When you subtract two dates you get number of days. You can convert number of days to minutes and then compare
it to 5 minutes.
Below I'm subtracting two dates which are 5 minutes apart and the statement makes a check on the difference
to output appropriate message:
SQL> select DECODE(((sysdate + (6/(24 * 60))) - sysdate) * (24 * 60), 5, 'YES', 'NO') from dual ;
DEC
NO
1 row selected.
SQL> select DECODE(((sysdate + (5/(24 * 60))) - sysdate) * (24 * 60), 5, 'YES', 'NO') from dual ;
DEC
YES
1 row selected.

Hi,
I have created some sql command UDMs and I want to extract their values so I can do some calculations.
I have 11.1 database
Thanks in advance for your help.
Regards,
SagarHi Sagar,
you can get current values using:
select target_type, target_name, metric_label, column_label, value, key_value
from mgmt$metric_current where target_name = :TARGET_NAME
and metric_label = 'User-Defined SQL Metrics'
order by column_label
for the history of a metric you need to use mgmt$metric_hourly, mgmt$metric_daily

How to extract Attribute Value from a DBC file with LabWindows and NI-XNET library
Hi all,
For my application, i would like to feed my LabWindows CVI Test program with data extracted from *.dbc file (created by another team under Vector CANdb++).
These files contains all CAN frame definition
and also some extra information added to :
Message level,
Signal level,
Network Level
These extra information are set by using specific ATTRIBUTE DEFINITIONS - FUNCTIONALITY under Vector CANdb++
The opening of the DataBase works under NI-XNET DataBase Editor as in LabWindows using: nxdbOpenDatabase ( ... )
No attribute seems be displayable under the NI-XNET DataBase Editor (it's not a problem for me)
Now, how, using the NI-XNET API and CVI, be able to extract these specially created attributes ?
Thanks in advance.
PS : In attached picture, a new attribute called Test_NI, connected to a message

EX1.jpg 36 KBHi Damien,
To answer your question on whether the XNET API on LabWindows/CVI allows you to gain access to the custom attributes in a DBC file, this is not a supported feature. The DBC format is proprietary from Vector. Also, custom attributes are different for all customers and manufacturers. Those two put together make it really difficult for NI to access them with an API that will be standard and reliable.
We do support common customer attributes for cyclic frames. This is from page 4-278 in the XNET Hardware and Software Manual :
"If you are using a CANdb (.dbc) database, this property is an optional attribute in the file. If NI-XNET finds an attribute named GenMsgSendType, that attribute is the default value of this property. If the GenMsgSendType attribute begins with cyclic, this property's default value is Cyclic Data; otherwise, it is Event Data. If the CANdb file does not use the GenMsgSendType attribute, this property uses a default value of Event Data, which you can change in your application. "
Link to the manual : http://digital.ni.com/manuals.nsf/websearch/32FCF9A42CFD324E8625760E00625940
Could you explain us the goal of this attribute, and what you need it on your application.
Thanks,
