Using expression builder

hi,
how can i use where condition at expression builder at admin tool, can you share sytax please?

Hi,
Whenever you click on the expression builder the syntax will be shown to you as soon as you click on the functions or any object you select.
In the logical table source, content tab, where clause, whatever condition you specify it gets reflected in the query when ever you pull the columns from the table.
For example-
If you are specifing the condition as
Region_name='Asia'
Then when ever you pull the columns from the table then the data will get restricted with 'Asia' data only.
You can als call functions, session variables.
Hope this helped/ answered.

Checking for empty tags using expression builder for XPATH

I am creating several filters in a mediator for several parallel paths. I am trying to route the mediator to the correct DB adapter based on what tags are empty in the incoming XML. The XML has 1 required tag and 3 optional. So for the expression, I am using the expression builder to load the tag name then putting either [text()] or [not(text())] immediately after each tag with an "and" in between for the 3 optional elements. The problem I am having is they always return false. For example, if I enter a value for an optional tag and put [text()] after it, it evaluates to false. What is the correct way to check if an element has text or not?
Thanks in advance!

Hi,
Its not recognizing the getVariableData func... instead try this:
string-length(xpath)>0
ex: string-length($in.body/imp1:manoj/imp1:C1)>0
It works... Happy deploying ... :)

Can't retrieve username using expression builder on a run time data control

Here's the scenario:
1. I added a Data Control resource in WebCenter Spaces, which has one paramater to get: username.
2. I added the Data Control in Oracle Composer, and selected the return method to show as a read only form.
3. In adding the Return method, under DC Parameters I have to get the username and place it on my parameter, ie: arg0 = username. arg0 is my data control parameter.
I tried using every possible code there is in the Expression Editor to retrieve the username, but I keep getting null when I test it. I've tried *#{securityContext.userName}*, *#{webCenterProfile[securityContext.userName].userName}*. I also tried creating a page parameter, and use it like this: *#{bindings.myUsername}*, but still won't work. Its always null.
How do I retrieve the username and bind it to the parameter of my data control using expression editor? Please help. Thanks.

Object type mappings in expression builder

Hi,
I'm trying to use expression builder to give me a query returning all instances of an object with a particular foreign key, and where 'active' = true.
'active' is a CHAR field in the database with values 'T' or 'F' and this is mapped to a Boolean in workbench as true and false.
All works fine in normal operations, retrieving and writing the data.
I've written the expression as
myId EQUAL arg
AND
active EQUAL 'true'
where 'true' is a literal of type Boolean.
Unfortunately, running this query generates an error that no mapping exists for 'true'.
I've also tried changing it to
active EQUAL 'T'
where 'T' is a literal of type String.
This also generates an error.
It seems to me as though the object type mapping is confusing the expression builder and it can't generate the sql correctly.
Any ideas?

Can you post the specific version of TopLink, the exact code you are using to construct and execute your query, as well as the error message with stack trace. With these items we should be able to provide an answer for you.

Expression Builder In Oracle Rule Authoe

Hi,
I am using expression builder for making this kind of expression:
x = y* (new Double(.02))
where x and y are Double.
after inserting the variables and operator, validation always fails showing the following message:
Cannot perform operation. 'RUL-01726: Data type operator for *, at position 10: java.lang.Double * java.lang.Double '
Please tell me where i am going wrong. It's very urgent.

Thanks for the reply Phil.
I think that when I am updating datamodel, it is updating every thing in data model i.e. variables, constraints, functions, facts everything.
Do you have knowledge of any method in the API which updates only variables??
Also, i followed a different methodolgy be using RuleSession. have a look at code snippet:
String rsrl ;
* Double testValue = 6000.0;*
* Double discount = new Double(0);*
* try {*
* rsrl = dict.ruleSetRL( ruleSetName );*
* String dmrl = dict.dataModelRL();*
* RuleSession session = new RuleSession();*
* session.executeRuleset( dmrl );*
* session.executeRuleset( rsrl );*
* discount = (Double)session.callFunctionWithArgument("DM.calculateDiscount",testValue);*
* System.out.println(" Discount "+discount);*
* } catch (Exception e) {*
* e.printStackTrace();*
Here instead of updating dataModel i am executing ruleSet using session and callingFunction to calculate discount.
Now if disocunt is populated independent of any other vairable (e.g. discount = 10.0d instead of discount = 10.0*salesValue)
then it should work. But if discount is dependent on some variable (which has to be global Variable) then it would not populate it.
This is what i have thought.
But the above code snippets always give following exception :
oracle.rules.rl.exceptions.InvocationException: wrong argument type in function or method invocation
even when function takes arguments in my dictionary.
Your help is much awaited!! Thanks in advance.

Expression Builder OBIEE 11g

Trying to calculate the percentage, but its giving me null values. Please tell me what's wrong.
Expression was built using expression builder in the RPD.
IFNull(("column" / "column"), 0)*100
When the column numbers are the same, it gives 100% like it should....
When the column numbers are different, it gives a 0 value.

Hey,
Sorry for the late response. No for some reason it didn't work. It's not a pressing requirement, but it's still looming over my head. I was told maybe I need to cast it, what do you think?

Adf expression builder substring function

Hello,
I'm new to adf and I want to make substring using expression builder. I've tried #{fn:substr(bindings.getSysdate.result,1,5)} but doesn't work and I didn't find on the net.
Please help.
Thank you

Hi,
the JSTL function is called fn:substring and - as Timo mentions - you need to add
xmlns:fn="http://java.sun.com/jsp/jstl/functions"
to the jsp:root tag of the JSPX page
This here then worked for me:
#{fn:substring(bindings.employeeName.inputValue,1,3)}

Using Decode in Expression Builder...

Hi everybody,
I want to use the DECODE function of SQL in an Expression Builder....
Of course this function does not exist in any of the transformation categories(arithmetic,character,e.t.c.) in the expression builder.
I have read in the OWB on-line help that in the Expression Builder there should be an 'Others' drop - down list in order to select any of the available SQL clauses - one of them is 'decode'...
The problem is that this drop - down list in the Expression Builder is disabled.....
How can I use this function anyway..????
Instead of using ... in the Expression Builder...
decode(<column_name>,'1','val_one','2','val_two') what can I use to do the same....???
As regards the problem that the drop-down list is disabled , what may be the cause..???
I use Microsoft XP machine , Oracle 10g (v.10.2) and OWB v.10.1.0.4
The documentation says....
"This allows you to deploy the DECODE functionality in all operating modes (setbased, rowbased, etc.) and transparently across Oracle database releases (8.1, 9.0 and 9.2)."
The above means that the cause is the incompatibility..????
Thanks , a lot
Simon

I am using OWB 9.2.0.8 and I can't reproduce the problem you are having with 10.1, but did you try just typing it into the expression?
Or, better yet, use CASE. The syntax is easier to read. I think OWB translates DECODEs to CASE when the SQL is generated.
(Case <column_name>
When '1' Then 'val_one'
When '2' Then 'val_two'
End)

How to use SQL OVER and PARTITION BY in OBIEE Expression Builder??

Hi there,
I want to create a new logical coulmn with the following SQL query.
SUM(Inventory Detail.Qty) OVER(PARTITION BY Inventory Detail.A,Inventory Detail.B,Item.C,Inventory Detail.D,MyDATE )/SUM(Inventory Detail.Qty) OVER(PARTITION BY Inventory Detail.A,Inventory Detail.B,Item.C )
How to use the OVER and PARTITION BY in OBIEE Expression Builder??
Thanks in Advance

hi bipin,
We cant use by in Expression builder(rpd) .But use the same formula like this in Fx of answers
SUM(Inventory Detail.Qty) OVER(PARTITION BY Inventory Detail.A,Inventory Detail.B,Item.C,Inventory Detail.D,MyDATE )/SUM(Inventory Detail.Qty) >OVER(PARTITION BY Inventory Detail.A,Inventory Detail.B,Item.C )SUM(Inventory Detail.Qty by Detail,ITEM,Mydate)/SUM(qty by detail,item)
First check the numerator whether it was giving correct results or not then go with denominator
compare the results with sql that u have
Let me know if that does work
thanks,

Did you try to deploy the mapping ? Some time the expression validator gives wrong error messege.
Try to deploy the mapping and see if you are still getting this issue

Can multi-select picklist be used in Expression Builder?

Does CRMOD allow the use of multi-slect picklist in Expression Builder within workflow?

Thanks Suddu your process worked. This can be done it is just a little more manual than being able to select the field from the drop down list.
To do this go to Admin, Application Customization, choose your record type, then Field Setup. Click on Rename Fields, then Advanced and copy the multi-select picklist field. Paste it into expression builder and at the end of the name add _ITAG. You will also need to add the brackets as well. Doing this will allow you to use a mspl in expression builder.

Using managed bean method in expression builder

Hello,
I'm new to adf and I have the following problem.
I have a managed bean in session scope that has the following method:
public boolean alertMessages() throws NamingException,
SQLException {
if (condition)
{ return true;}
else
{return false;}
I have a page that has a link. Using the expression builder and according the function result I want to make the link bold or not.
I use the expression #{sessionScope.backing_pages_index.alertMessages ?'bold':'normal'} but it does'n work.
Could anybody help me.
Thank you,

Hi..
If you add your bean as sessionScope No need to add sessionScope to EL front,and should setter and getter for alertMessages
use *font-weight:#{backing_pages_index.alertMessages ? 'bold':'normal'}*
try as follows it is working for me
> private boolean alertMessages;
> public void setAlertMessages(boolean alertMessages) {
> this.alertMessages = alertMessages;
> }
> public boolean isAlertMessages() {
> if (true) {
> return true;
> } else {
> return false;

<af:commandLink text="commandLink 1" id="cl1" action="CustomPage"> inlineStyle="font-weight:#{backing_pages_index.alertMessages ? 'bold':'normal'};"/>

Expression Builder: convert string to number

Hi all,
I'm having trouble building a field validation rule for bank account numbers.
The numbers have 12 positions, so I cannot use a string or text number.
The validation rule to be implemented is that the last two digits are calculated based on the first 10 (modulo 97).
However, when I use the Mid function to pick the first characters, I am unable to do any calculations on it. Apparently, the string to number conversion doesn't work (it should work when I read the manual, as it says that when using an operator between two data types, the second type is converted to the first (cf. example of 1234+abcd (should result in 1234 as to the manual))). So I tried '1*Mid(...)' or '0+Mid(...)'. Syntactically the expression builder accepts it and I can save it. BUT when I change the particular value on the screen, it gives me an SSO error (not the Field Validation error message I entered).
Why isn't there simply a function ToNumber (like ToChar)????? How could I workaround this?
Any input very welcome!
Frederik

Apparently, I was a bit confused when typing the first sentence, it should be:
The numbers have 12 positions, so I cannot use an integer or number data type, but have to use String.

Human Task – Using expressions in task parameters

Hi All,
In my BPEL process I have a Human Task with about 15 task parameters. I'm trying to define BPEL variables to each and every parameter. I am able to select a type 'variable' variable (ie. /ns18:OutputParameters/ns18:street_name) from tree view and save.
However, whenever I click on the little flash-light icon and create a type 'expression' using the XPath expression builder I'm having problems saving the change.
In details this is what happens,
0.) Double click on Human Task
1.) Click on flash-light icon in front of a parameter.
2.) Select Type expression variable.
3.) Click XPath expression builder.
4.) Select conversion function 'string()' and double click to add.
5.) Double click on the required BPEL variable to add.
6.) Something similar to the following expression is created,
string(bpws:getVariableData('InvokeGetAllABCInformation_FetchABCInformationService_OutputVariable','OutputParameters','/ns18:OutputParameters/ns18:ACC_ID'))
7.) Click OK twice and then Apply/OK to go back to BPEL diagram view.
8.) Now at this point the BPEL is not saved and the tab-title is italic to show it’s unsaved.
9.) Save the BPEL to disk.
10.) Double click on the Human Task to show parameters and variables defined.
11.) The previously defined expression type variable is still there.
12.) However now if I click either 'Apply' of 'OK' buttons without making any changes the BPEL diagram tab-title becomes italic and when the BPEL is saved to the disk, it forgets about all the expression type variables that was previously defined. Also note that cancelling wouldn't change anything.
This is a serious issue as I can't change any setting to a Human Task parameter list, as every time I make a change, I loose all the expression type variable declarations.
Could this be a bug in JDeveloper?
My JDeveloper Studio Edition Version is: 10.1.3.3.0.4157
Any help on this would be greatly appreciated.
Thanks.
Shaminda.

ok, looks like no one knows what's going on,
Here's the workaround that I came up with, If anyone is interested.
Create a custom XSD (schema) with required variables in it (to be used by expression types vars), and use a copy operation before the human task and create the expression types in there. Then use the schema to map the values to the human task.
