Data model with decimal point in aggregate functions

Hello

In the data model when a summary aggregate function type is created, the decimal fields are displayed with ',' instead of '. '.

Is it possible to tell displayed with decimal BEEP '. '?

I solve it by copying the CS attribute and create a new by an element of expresion.

The Siebel data model with attribute mapping rule OPA?
Hello

Someone at - it has mapped siebel attribute of data model with the attribute rulefiles (rule of word doc file) (for example, p1, p2, p3... generated automatically)?

I imported the siebel data model in OPM version 10.2. He created siebeldatmodel.xsrc file. all siebel attribute created with ID, model ID with the same name as the name attribute of siebel. but in the rulebook, we attributte with p1, p2, p3... names etc.

The problem I am facing at I'm not able to map the attribute siebel generated with attribute (p1, p2, p3) rule book

Any quick suggestions of experts will be very apperciable.

Thank you
There are a few simple rules for text attributes.

1. unless the attribute belongs to the global level, the attribute must have the text of the entity included in its text. Thus, if the attribute belongs to the 'contact' it must understand that in its text. The possible options are:

"* the contact work country."

"the country of work of * the * contact."

2. you cannot have two attributes with the same public name or the same text. So, you will get an error if you have two attributes with the same text "the country of work.

Binding data model with a & quot; for in & quot; loop
I have a model of data representative of the form elements. The item element and shape the data model looks like this:
< data_model >
< item_1 > {item1.text} < / item_1 >
< / data_model >

< mx:DateField id = text = "{data_model.item1}" / "item1" >

I retrieve data from a database in an associative array and convert it to an ArrayCollection collection as follows:

formData = new ArrayCollection (ArrayUtil.toArray (re.result));

Now, if you do:

data_model.item_1 = formData ["item_1"];

the text of the form element item1 updates I expect through the connection between the two. If I browse the table as such:

for (var key: String in formData) {}
data_model. Key = formData [key];
}

the model is updated, but the form element text field is not. I would love the convenience of iteration on the table instead of having to type by hand all the model elements. Ideas?
Figured it out. Instead:

data_model. Key = formData [key];

follow these steps:

data_model [key] = formData [key];

So stupid

Data model with ImageView not displaying the image on OS10.1

in the qml, I have a ListView with a DataModel. The DataModel contains a label and ImageView.

I put the ImageView and etiquette like this

Entry QVariantMap;

QFile file (picture_file); file stored on the device
QFileInfo fileInfo (file);
QString qmlPath (fileInfo.absoluteFilePath ());

the path of the file would like something like that

/Accounts/1000/APPDATA/com.example.TestApp.testDev_e_TestApp4a417186/shared/photos/TestApp/MyPicture.PNG

entry ['image'] = QUrl (qmlPath);
entry ["name"] = "Text";

It works on 10.0.9 but when I recompile the target app to 10.1 or the image is not displayed. The label is.

Also, if I set the imagesource to the current folder the image appears fine.

entry ['image'] = "asset:///images/template.png";

What is the correct way to set the imageSource for ImageView?

I think your problem will be solved by file:// adding to the path of your file.

return a SUCCESS;
}

public BigDecimal ODCIAggregateMerge (oracle.sql.STRUCT ctx2) throws SQLException {}

return a SUCCESS;
}
}

To implement this in the database, I use the following script:

CREATE OR REPLACE TYPE IMPROG. SECONDMAX_J as object

(
INTEGER key,

public static function ODCIAggregateInitialize (sctx IN OUT SECONDMAX_J)

Return number
IN THE JAVA LANGUAGE

);
/

CREATE OR REPLACE FUNCTION F_SECONDMAX_J (NUMBER value) RETURN NUMBER

PARALLEL_ENABLE

AGGREGATION to the HELP of SecondMax_j;
/

When I now use the F_SECONDMAX_J function.

"(Columnname) select F_SECONDMAX_J from Tablename t;

It works perfectly and shows me the right result.

Then I tried to implement the fusion part as follows:

public BigDecimal ODCIAggregateMerge (oracle.sql.STRUCT ctx2) throws SQLException {}

BigDecimal Key2 = null;

BigDecimal ctx_max = null;
BigDecimal ctx_secmax = null;

BigDecimal ctx2_max = null;
BigDecimal ctx2_secmax = null;

retrieve the context stored with the key
StoredCtx_SecMax ctx = null;
try {}
CTX = (StoredCtx_SecMax) ContextManager.GetContext (Key.intValue ());
} catch (Exception e) {}

}

Object [] impAttr = ctx2.getAttributes ();

Key2 = (BigDecimal) impAttr [0];

retrieve the second context stored using the key2
StoredCtx_SecMax ctx_sec = null;
try {}
ctx_sec = (StoredCtx_SecMax) ContextManager.GetContext (key2.intValue ());
} catch (Exception e) {}

}

ctx_max = ctx. LeseMax();
ctx_secmax = ctx. LeseSecMax();

ctx2_max = ctx_sec. LeseMax();
ctx2_secmax = ctx_sec. LeseSecMax();

If (ctx2_max.compareTo (ctx_max) == 1)
{
If (ctx2_secmax.compareTo (ctx_secmax) == 1)
{
CTX. SchreibeSecMax (ctx2_secmax);
}
on the other
{
CTX. SchreibeSecMax (ctx_max);
}
CTX. SchreibeMax (ctx2_max);
}
on the other
{
If (ctx2_max.compareTo (ctx_secmax) == 1)
{
CTX. SchreibeSecMax (ctx2_max);
}
}

return a SUCCESS;
}

When I now try the function

"Select / * + parallel (t 4) * / F_SECONDMAX_J (Columnname) of Tablename t;

I always get a pointer NULL-error because the variable key2 is always 0 and therefore the functions LeseMax() and LeseSecMax()
in the second context 'ctx_sec' produce this error NULL pointer.

To me it seems that each parallel process is the construction of an additional class for himself, which is not available are my main process.

My question is now how it is possible to access the context of stored of the parallel process, so that I can combine the results.

Thank you very much

Josef
Hi Josef,

just guess that I've never implemented with java user-defined aggregate functions or support parallel execution:

Maybe you have to implement ODCIAggregateWrapContext?

+ Application of ODCIAggregateWrapContext is optional. It should be implemented only when the external memory is used to hold the aggregative, context and the user-defined aggregate is evaluated in parallel (which is, stated as PARALLEL_ENABLE). If the user-defined aggregate is not evaluated in parallel, ODCIAggregateWrapContext is not necessary. +
[http://docs.oracle.com/cd/B12037_01/appdev.101/b10800/dciaggfns.htm#i1004974]

Report it to progress and success.

Group data model does not

Hello

I am developing a revision update for my app BB10 stunts and I use a data model to pull in the elements of the application do not forget; the only problem I encounter is that I can't get the data model of the group work so that I can arrange the items by the first character instead the data are currently presented as Z - A, even if I could get it to display in A - Z would be enough, but what I am looking to achieve is to get the model to display in A - Z and then sort by the first character, while a header for each letter is displayed.

May require alterations, I have not tried this compilation.

How to model a view based on a function table
Hello

I want to model a view in SQL Developer Data Modeler which is based on a function of painting as:

table (function (a, b))

When the function is a function table in pipeline. How is that possible?

DM 3.3.0.734 SQL version

Best regards

Joop
Hello

In the Properties dialog box of the view that is displayed when you create the view, you can select the Report Builder queries (on the general page) button.

In the query designer, you can enter the query text in the box above the buttons OK and apply, cancel, for example
SELECT * FROM TABLE (FUNCTION (a, b))

Problems of decimal Point with easy Excel Table VI and Excel 2007

Hello

We used the Excel simple table VI transfer to Excel 2002 LabView measurement data. Now, we have updated our Excel for Excel 2007. After that, there is something wrong at the time of the transfer of LabView to Excel. It seems that excel now ignore the decimal Point.

Hi Martin,

It is a known issue with LV, excel and the European regional settings.

To work around the problem, do the following:

To transfer the correct data to Excel, disconnected "use localized comma" in tools-> Frontpanel.

You can use the "." instead of ',' when you enter numbers, for example "0.99" instead of "0.99".

Probable bug with decimal data type mapping in storage of XmlType relational object

Hello
I'm having a problem with what appears to be a bug me when Oracle creates the mapping object / relational schema for a data type "XSD: Decimal":
I want to store geo codes 6 fractional digits, so I need to 3 digits to the left and 6 digits to the right of the decimal point.
In the XSD data type restrictions, which would give me a 'fractionDigits' and a 'totalDigits' 9 6.
Oracle must convert this number (9, 6).
However, what Oracle made out that is a NUMBER (15.6)
In order to get an Oracle to generate a NUMBER (9, 6), I need to qualify the 'totalDigits' 3, which is accepted by Oracle, but makes my schema invalid for virtually any other application XML, because it violates the official specs of XSD:
http://www.w3.org/TR/xmlschema-2/#RF-fractionDigits:

4.3.12.4 constraints on fractionDigits components of schema

Schema component constraint: fractionDigits less than or equal to totalDigits

It is an error for fractionDigits is greater than totalDigits.

Is it possible to have the good totalDigits of 9 in my scheme and force the Oracle to translate that into NUMBER (9,6)?
Maybe some attribute oraxdb I do not know yet?
I'm surprised that this has not been found earlier.
There was an announcement about this before, but he did not get the real answers:
TotalDigits and fractionDigits to number conversion problem
Here is my complete code example:
```
-- Registering the schema
BEGIN
DBMS_XMLSCHEMA.REGISTERSCHEMA(

  );
end;
/
```
In the XSD data type restrictions, which would give me a 'fractionDigits' and a 'totalDigits' 9 6.

Oracle must convert this number (9, 6).

And that's where you're wrong.

fractionDigits = 6 means at least 6 digits located to the right of the decimal point.

This is different from the semantics of NUMBER (m, n), where n is exactly n fractional digits stored.

123.456789 is a valid number by the XSD.

123456789 is as valid a number, but of course it does not fit in a NUMBER (9.6).

Oracle must create a NUMBER (15.6) to store any number of valid schema, it is a necessary condition.

But this is not a sufficient condition: obviously, any number in a NUMBER (15.6) is not valid per the XSD, and this is where the schema validation occurs to enforce the constraints of two facets.

Here are some examples:

Problem with my aggregate function

Hello

I tried to build my own global function in the chain, but I have a problem when I use it in my application. When I'm with her, he wrote ORA904, considering that this idenfifier exists. Do you know what is the problem?

here my aggregate function:

create or replace FUNCTION aggme (query_in in VARCHAR2) RETURN VARCHAR2 IS
    incoming    varchar2(4000);
    hold_result varchar2(4000);
    c sys_refcursor;
Begin
    open c for query_in;
    loop
        fetch c into incoming;
        exit when c%notfound;
        hold_result := hold_result||','||incoming;
    end loop;
    return ltrim(hold_result,',');
END;

and here my request using my aggregate function aggme:

select
  RES.LASTNAME as "LASTNAME",
  RES.FIRSTNAME as "FIRSTNAME",
  aggme('select NAME from PATHOLOGY where ID= RES.PATHOLOGY_ID') as "PATHOLOGY"
from
  TBK_RESOURCE RES

Hi BluShadow,

I followed your advice and try to use the aggregation of clob. No problem to compile the function but when I use the clobagg to my query, is not aggregated. Perhaps, I don't use it correctly.
select
RES.PATIENT_LASTNAME as "LASTNAME",
RES.PATIENT_FIRSTNAME as "FIRSTNAME",
(select trim(',' from clobagg(name||',')) as "pathology" from pathology where ID= RES.PATHOLOGY_ID)
FROM
TBK_RESOURCE RES
output, I have:

FIRSTNAME. LASTNAME. PATHOLOGY
TOTO | OTOT | ACB
TOTO | OTOT | GB

instead of having:
TOTO OTOT ACB, GB

Well, I don't have data to work with, but it works well for me...

Feature rounded with 2 decimal Point in JAVA Sciprt

Hello

I calculate using java script.
I need the round function in JAVA script.

My code is

<script type="text/javascript">
     function getVal(pNd){
          return ($v(pNd)!= "")?parseFloat($v(pNd)):0;
     }
     function grossamt(){
        $s('P2_GROSS_AMT',getVal('P2_TAX_ON_AMT')-(getVal('P2_TAX_ON_AMT')*getVal('P2_TAX'))/100);
$s('P2_GROSS_AMT_1',getVal('P2_TAX_ON_AMT')-(getVal('P2_TAX_ON_AMT')*getVal('P2_TAX'))/100);
$s('P2_TAX_AMT',(getVal('P2_TAX_ON_AMT')*getVal('P2_TAX'))/100);
$s('P2_TAX_AMT_1',(getVal('P2_TAX_ON_AMT')*getVal('P2_TAX'))/100);
$s('P2_NET_AMOUNT',getVal('P2_GROSS_AMT')+getVal('P2_TAX_AMT'));
$s('P2_NET_AMT_1',getVal('P2_GROSS_AMT_1')+getVal('P2_TAX_AMT_1'));     }
</script>

How to apply the function round with 2 decimal Point

 $s('P2_GROSS_AMT',getVal('P2_TAX_ON_AMT')-(getVal('P2_TAX_ON_AMT')*getVal('P2_TAX'))/100);

It would be more readable if you create a variable and do

var  x = Your complex formula to get the value

   x = Math.round( x * 100)/100;

I can create forms in the designer, but when I use a data model, I can't interact with the form

In LiveCycle Designer ES2 I can create a form and then preview and interact with the form.
This guess I just build objects by dragging the pieces pre-made object on the form (for example, text field) - which I can name, wrap in subforms something - I can add actions and all is well. When I preview the PDF, I can enter data in the fields, click on the radio buttons, making things appear that everything is great.
But LC ES2 is based on the data driven development model by, so in my case I need a form guide as well as the form - so it's better to have a model of data created in the first place - and then create the form based on the data model - then build guide form based on the data model - it is also a good idea, and I'm cool with that.
My problem is that when I'm building a data model (just for a quick and dirty development demo, not associated with services back-end or databases) and I create the form based on the data model - I can't interact with all objects in the preview pane form - further when I launch the workspace and call my process that contains the form - I even can't interact with the form.
What I am doing wrong?
Summons - I can create a form and interact with it - but If I start with a data model and generate the form based on that - I can't interact with the form (option buttons click-I can not enter data in form fields - etc) what causes this? What should I do to use a data model and be able to create an interactive form? >
Does anyone know what causes this problem? It's driving me crazy.
Thank you-
Ben

You do not hurt anuthing. It works as advertised. When you generate a Guide and work with a fml data model designer you will only create a static non-fillable PDF file. This is because when you import the model in the designer of the model must be turned in a schema. The schema may not represent constraints and validations can be encoded in the model. The only thing that can be maintained is the structure, so Designer forbids you to buidl an interactive form.

If you know what you're doing, you could take the data it is generated from the Guide and merge on a XDP template file that you create (unless he models in a first time - you can use the sample XML data as a starting point) using LC forms. Edowmside, is that if there are constraints and rules you would have to code them in the model as well. That's the way it is now there, but it will improve over time, as more of the ability of the model is exposed to the XFA world.

Hope that helps

When you use Excel or my Peachtree Accounting program, entered digital as "$152(32 in the accounting package or the same number with a square symbol as the decimal point in Excel.)". No idea what I should check first?
