Expression syntax
Hi
In an "ADF Task Flow", i'm trying to use a router to select which page will show base on the result from a query (if empty, page A, else page B).
There is alot option in expression builder of the router.. but not much related to the results of my query?!?
Thanks for your help
Ben
note: I'm using jdev 12c
Not exactly your use case, but it should get you started. The key is to execute the vo query first and then check if the iterator returned zero rows or more than zero rows.
Check http://tompeez.wordpress.com/2012/12/01/jdeveloper-11-1-1-5-0-use-router-to-create-new-row-or-edit-existing/for more info.

Expression syntax in TestStand 4.0 tutorial
Hello All
Teststand is new to me, and I am trying its tutorial with "Using TestStand" manual.
At the Using TestSTand page 3-7, Insert a Template Step step 7, we insert a
message popup "Retry if Previous Step Fails". This step has post action "Goto Step",
but it doesn't goto next step and uses an expression "RunState.PreviousStep.TS.Id".
I can't find the expression at the expression browser and don't know what this means.
There is a RunState.PreviousStep at the expression browser but no "TS.Id".
I've attached a pic (teststand_ques.jpg) to show the expression. Could anyone
tell me its meaning.
Also, is there any manual or guide of TestStand expression syntax? I know expression
browser shows its operator and functions, but I'd like to have a detail reference manual.
Thank you

teststand_ques.JPG 214 KBHi,
The TS is a hidden property of the Step.
You can unhid this property by a setting in the Station Options select the Preference Tab.
You actually dont need to enable this setting, you could of just typed it in (, the .TS.id I mean). But when learning it is handy to see all the properties.

Assignment Expression Syntax Guide
Hi,
Can somebody point out the material on Assignment Expression syntax in MDM. Where i can find list of all available operations with some sample code. Somebody pointed out in another thread the IS_UPPER and UPPER are functions but they don't appear in the drop down.
I also need to know:
1. How can the items be accessed that donot have a direct relation with the table of the Assignment.
2. How can i update multiple fields in single assignment (especially since we don't have assignment groups).
I am using SAP MDM 5.5 SP5 P4
Thanks

What is the expression syntax to make the visibility of a column hidden in a Tablix?
So if my Parameter value is...
MCCL, MCMA, MCPL, MCPR, MCRE, MCSE, MCSN, MCVA, MCCL, MCEP, MCMA, MCRE out of 43 possible choices, what is the expression syntax to hide my tablix column based on my parameter value?
=iif(instr(Join(Parameters!ColumnVisibility.Value,","),"MCCL","MCMA","MCPL"...)>0,false,true)
Just not sure of the syntax...or do I have to qualify each one???
= IIf(Parameter!PF1.Value = "MCCL" OR Parameter!PF1.Value = "MCMA"..., TRUE, FALSE)Hi ITBobbyP,
Per my understanding that you have create multiple values parameter "ColumnVisibility" based on the fields LineofBusiness and the fields LineofBusiness have the n to 1 relationship with the BusinessUnit like below(Sample Data):
When you select values from the dropdown list which only include the "FM" or "MC", the column "HCFNumber" will show or it will hide, right?
If so, If you have two many values in the lineofBusiness mapped of the BusinessUnit, you can create an new cascading parameter "BusinessUnit" based on the BusinessUnit field like below:
select distinct a.BusinessUnit from (select 'MCCL' lineofBusiness, 'MC' BusinessUnit ,11 HCFANumber
union
select 'MCCS' lineofBusiness, 'MC' BusinessUnit ,11 HCFANumber
union
select 'COLG' lineofBusiness, 'CO' BusinessUnit ,11 HCFANumber
union
select 'COSM' lineofBusiness, 'CO' BusinessUnit ,22 HCFANumber
union
select 'FMMS' lineofBusiness, 'FM' BusinessUnit ,33 HCFANumber
union
select 'FMCG' lineofBusiness, 'FM' BusinessUnit ,44 HCFANumber)a
where lineofBusiness in (@LineofBusiness)
Add another filter in the (@BusinessUnit) and use expression below on the column visibility:
=IIF(Join(Parameters!BusinessUnit.Value,",")="FM" or Join(Parameters!BusinessUnit.Value,",")="MC" or Join(Parameters!BusinessUnit.Value,",")="FM,MC" , false,true)
Preview like below:
If you still have any problem, please try to provide more details information about the expect result you want to get based on the show/hide.

Method expression syntax error in jsp jsf 2.0 eclipse
hi i made a simple bean jsp project, n ussed el to call methods in backing bean n show some text on the basis of method called....
the project works perfectly fine, but theres a small issue, that eclipse jsp editor marks the expression as red n shows err.. the proj deploys fine on tomcat, n even works fine with expected results...
wat should i do to fix that err show by eclipse...
using eclipse helios with wtp 3.2, tomcat 7, jsf 2.0, el-api n el-impl 2.2 version jars in tomcat lib.... n latest jstl n standard jars...
eg of jsp call - <h:outputText value="#{myJsfBean.fetchCourseName(studentBean.courseId)}" />
backing bean fn -
public String fetchCourseName(Integer iCourseId){
String theCourseName="";
for(CourseBean aCourseBean:courseBeanList){
if(aCourseBean.getCourseId().equals(iCourseId)){
theCourseName=aCourseBean.getCourseName();
break;
return theCourseName;
jsp editor show err - Multiple annotations found at this line:
- Syntax error in EL
- Expression must be a value expression but is a method
expression
for "#{myJsfBean.fetchCourseName(studentBean.courseId)}" part of the expression
its a trivial issue i think but annoying,, tried to search alot cudnt fix it....
plz helpmy guess is that the project is not setup as being a JEE6 project and is being validated it as if it is a JEE5 application; the ability to be able to call methods with parameters through an EL expression is a new feature of JEE6 (or to be more precise: the el 2.2 API).
Perhaps you can specify in your project properties that this is in fact a JEE6 project? Eclipse Helios should support JSF 2.0 out of the box. -

Generic Alert Log Expression Syntax
Can anyone explain or point where I can understand the syntax allowed for expressions for monitoring the alert log? For example :
ORA-0*(600?|7445|4[0-9][0-9][0-9])[^0-9]Are you asking what 'ORA-0*(600?|7445|4[0-9][0-9][0-9])[^0-9]' means?
If so, its just a perl expression. look on google for searching patterns etc in perl and then change it accordingly to what you want (or not) to search for.

FM9 SDL Authoring Assitant Regular Expression Syntax?
I'm trying to trick SDL into identifying words that are not approved by STE.
Under "Configure|Style and Linguistic Checks|User Defined Rules" the program allows regular expressions to create custom rules.
I have all other options in the Utility unchecked.
I am by no means a pro at regular expressions but was able to create a pretty solid command at http://regexlib.com/RETester.aspx.
The idea is to create an expression that looks for any word other than those seperated by vertical bars.
For the test text "this is not the way that should work. this is not the way that should work."
\b(?:(?!should|not|way|this|is|that).)+
returns: the work the work
At that website, I can change the excluded words and it works every time. Change the test text, same thing, still works.
Perfect! I ripped every approved word in STE into the formula and it (SDL) only returns words at the end of the sentence that are followed by a periods and question marks. So I added"\." to the exclusion list in the expression and it only found words next to question marks. I excluded question marks and now it finds nothing. I don't understand this as I wasn't aware that I had any criteria in the expression that dictates functionality only at the end of the sentence.
I have an O'reilly book to refer to, if anyone can give me a shove in the right direction as to which set of rules to adhere to, I would appreciate it. Why did negative word matching have to be my introduction to this subject?I tried your expression in a couple of regex tools and it seems to parse as you wanted it to. I suspect that the SDL implementation doesn't follow the unix/linux standards. I haven't used the tool and the usage documentation is non-existant, except for the limited flash-based demo.
From the SDL knowledgebase, it states that their regex filter uses the .NET regex flavour and I believe that the differences on this are explained in the "Mastering Regular Expressions" book. -
Hi,
I am writing the below program.
when case_not_found exception raises
can any one help me....
declare
i integer := 10;
l_result NUMBER;
begin
l_result:= CASE i
WHEN 1 THEN 2
WHEN 2 THEN 3
END CASE;
EXCEPTION
WHEN CASE_NOT_FOUND THEN
dbms_output.put_line(nvl(l_result,200));
end;Regards,
RajeshA case statement, when does not find an Appropriate match, raises a CASE_NOT_FOUND Exception.
On the contrary, the Case Expression, returns a NULL Value.
Since, you used a Case Statement, use the ELSE clause to return some value, say NULL, and the select statement will nto fail.
Modify it this way:
declare
i integer := 10;
l_result NUMBER;
begin
l_result:= CASE i
WHEN 1 THEN 2
WHEN 2 THEN 3
else NULL
END;
EXCEPTION
WHEN CASE_NOT_FOUND THEN
dbms_output.put_line(nvl(l_result,200));
end;Extract for Oracle Documentation
+"If the ELSE clause is omitted, the system substitutes a default action. For a CASE statement, the default when none of the conditions matches is to raise a CASE_NOT_FOUND exception. For a CASE expression, the default is to return NULL."+

Report Builder 3.0 Expression i am not able to make it work on Oracle DB Table
Hi,
I am newbie to SSRS Report Builder 3.0 so please be patient with me. I am trying to create a report to query Remedy Ticketing System and it uses Oracle Database installed on a Unix OS...My end objective is to do some calculation on the ticket metrics (i.e.
percentage of tickets closed within SLA, etc) however i am stuck from the very beginning where i am not able to make my expression work...
To begin with. my query statement...
Select Distinct TICKET_NUMBER, Assigned_Group, Category, REGION, TICKET_STATUS,EXCEEDED_SLA, TO_CHAR(date '1970-01-01' + (TICKET_CREATION_DATE/60/60/24), 'DD/MON/YYYY HH:MI:SS AM')TICKET_CREATION_DATE
from ARADMIN.Request
where (Assigned_Group like 'HOTS' OR Assigned_Group like 'PAID' OR Category like 'HVD%') and TICKET_CREATION_DATE > (TO_DATE('31/DEC/2014 11:59:59 PM','DD/MON/YYYY HH:MI:SS PM', 'NLS_DATE_LANGUAGE=AMERICAN') - DATE '1970-01-01')*60*60*24
order by ticket_creation_date
the data type of the oracle table:
Here is the Query Result of the DataSet:
Basically Ticket_Status has values from 0 to 4 although from the screenshot above you only see 2 and 4...
Ticket_Status 0 - Means Open Ticket
Ticket_Status 1 - Means Work In Progress Ticket
Ticket_Status 2 - Means Pending Ticket
Ticket_Status 3 - Means Awaiting Closure Ticket
Ticket_Status 4 - Means Closed Ticket
I created a chart column using the expression below but it did not work...what i mean by it does not work is that the chart column output shows all Ticket_Status total count including 0, 1, 2, 3, & 4 (i.e. total count of tickets are 206)...using
the expression i was only expecting the total count for Ticket_Status 4 (i.e. 180 tickets) but i guess i am doing something wrong with the expression syntax...
=Count(Fields!TICKET_STATUS.Value=4)
i also used the expression below but it did not work...
=Count(Fields!TICKET_STATUS.Value="4")
i converted the Ticket_Status to CHAR on the dataset using the TO_CHAR(Ticket_Status) AS Ticket_Status then i tried the expression below but did not work...
=Count(Fields!TICKET_STATUS.Value="4")
i tried again the expression below but did not work'
=Count(Fields!TICKET_STATUS.Value=4)
i cannot proceed to the arithmetic calculation if i cannot filter my dataset with the correct value...again i am a newbie with SSRS & report builder and i would appreciate it very much if you can guide/help me :-)Hi Danny,
Per my understanding that you can't get the expect result by using the expression "=Count(Fields!TICKET_STATUS.Value=4) " to count the the TICKET_STATUS which value is 4, the result will returns the count of all the TICKET_STATUS values(206)
but not 180, right?
I have tested on my local environment and can reproduce the issue, the issue caused by you are using the count() function in the incorrect way, please modify the expression as below and have a test:
=COUNT(IIF(Fields!TICKET_STATUS.Value=4 ,1,Nothing))
or
=SUM(IIF(Fields!TICKET_STATUS=4,1,0))
If you still have any problem, please feel free to ask.

How to write the expression when create the calculated column?
Dear,
I want to create some calculated column in my attribute view, but I don't know how to write the code in the expression, is there any introduction about this part, how to use those function and how about the grammar in this expression code ? or is there any example about this calculated column?
Thanks for your sincerely answer.Hi Zongjie,
you can find some information about the creation of calculated columns in the HANA Modeling Guide (http://help.sap.com/hana/SAP_HANA_Modeling_Guide_for_SAP_HANA_Studio_en.pdf).
Within chapter 6.2.1 (Create Analytic Views) you can see under point 7 some basics and also a simple example. The same is also valid for Calculation Views.
Chapter 8.9 (Using Functions in Expressions) describes the different available functions.
You also can use the integrated search in the HANA Studio by clicking the "?" button in the button left corner. Then you get some links in the side panel with related information.
In general you can write your expression manually or you can just drag and drop the functions, elements, operators into the editor window. For example if you drag and drop the "if" function into the editor window you get "if(intarg,arg2,arg3)" inserted. The arguments can be replaced manually or also by drag and drop.
It is also worse to use the "Validate Syntax" button on top of the editor window. It gives you directly a feedback if your expression syntax is correct. If not you get some helpful information about the problem (ok, sometimes it is a little bit confusing because of the cryptic error message format ).
Best Regards,

Hello list,
How do I go about DECODE function in expression?
It's legal only in SQL statement, so validation is fine, but when OWB deploys a script I have error message because DECODE is used in PL/SQL as well. I have solved it temporarly manually changing the script, but this is an error-prone method. What are other solutions except creating user transformation?
TIA,
AlexI have tried it, but it won't work.
For instance:
case INGRP1.CD
when 1 then 2
else 3
end
Gives the folowing error:
Line 1, Col 1:
PLS-00103: Symbool "CASE" aangetroffen terwijl een van de volgende werd verwacht:
( - + mod not null <an identifier>
<a double-quoted delimited-identifier> <a bind variable> avg
count current exists max min prior sql stddev sum variance
execute forall time timestamp interval date
<a string literal with character set specification>
<a number> <a single-quoted SQL string>
This means that the word CASE cannot be used as first.
Any suggestions? I cannot found any documentation about creating expressions (syntax, functions, examples).
Very sad, because it takes a lot of time to accomplish such a simple thing.

Maurice
