Evaluating a dynamic variable

Hi I'm trying to write a little function to create, populate and select defaults for list type drop down menus, what I have works, but there is a small problem.
The select control name is passed as an argument to the function:
        <li>
                <label for="type">Type</label>
                <select name="type" id="type" />
                    <cfscript>selectOptions('type','VehicleTypes','type','id');</cfscript>
                </select>
            </li>
When the function gets a hold of it it needs to be eveluated, I'm using 'evaluate()' - but I understand that there are problems with evaluate.
Is there another method to do this? [i.e. address the value of a dynamic variable] See below.
    <cffunction name="selectOptions" access="public" output="yes" returntype="string">
        /*------ unrelated code removed -----*/
        <cfscript>
            for (i = 1;i lte showoptions.recordcount;i++){
                vlu = showoptions[value][i];
                txt = showoptions[column][i];
                if(evaluate(formvar) is vlu){sel = 'selected="selected"';}else{sel=formvar&' '&vlu;}
                options = options&'<option value="'&vlu&'" '&sel&' >'&txt&'</value>';
            writeoutput(options);
        </cfscript>
    </cffunction>
-thanks

The main problem with evaluate is that it's slow. Array notation is faster. The syntax is:
Structure["constant part" & variable part]
The structure could be form, url, arguments, or a structure you created yourself.

Binding dynamic variable in XQuery doesn't work: ORA-00932

I have a table with several columns. One of those columns is a XMLType.
My goal is to have a query which selects rows from the table of which the XML column matches certain criteria.
I'm trying following example (JDBC) : http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28369/xdb_xquery.htm#insertedID11
First, I created my own query, which looks like:
select * from MyTable t, XMLTABLE( xmlnamespaces (DEFAULT 'http://test), 'for $i in /RootElement where $i/SubElement[contains(Element, "someValue")] return "true"' passing t.xmlColumn)This works as expected. Next, as done in the example, I'm trying to replace the "someValue" with a dynamic variable.
Query then looks like:
select * from MyTable t, XMLTABLE( xmlnamespaces (DEFAULT 'http://test), 'for $i in /RootElement where $i/SubElement[contains(Element, $val)] return "true"' passing t.xmlColumn, :1 as "val")This does not seem to work, neither in SQLDeveloper nor in java.
I always get the :
java.sql.SQLException: ORA-00932: inconsistent datatypes: expected - got CHAR(SQLDeveloper just gives ORA-00932)
When I put $val between quotes (so "$val") then I get no error, but then I get no results either.
I think it will not replace $val in that case but just use it as a literal, so thats not what I want
I also tried to remove "contains" xpath and use the exact same example as on the oracle page
select * from MyTable t, XMLTABLE( xmlnamespaces (DEFAULT 'http://test), 'for $i in /RootElement where $i/SubElement/Key = $val return "true"' passing t.xmlColumn, :1 as "val")But this doens't help either.
I'm clueless about this, so any help would be appreciated

Ok, I tested it using the latest enterprise edition (11g) and there it works as expected.
However, on 10.2.0.1.0 and 10.2.0.3.0 it gives this error.
Is this a bug which has been fixed or should I do something special on 10g ?
I installed all of these as normal without any special settings, created the tables and ran the query...

How do I use a dynamic variable from a prolog script?

I have my test broken in to three scripts, a login, an update, and a logout. There is a dynamic variable, SERVICE_VIRTUAL_CLIENT, from the login script that I need to use in the update script, but I can't figure out how to do it. Any help would be appreciated.
Edit: I forgot to mention that the login script is only run in the prolog portion of the UDP.
Scott

Scott,
You would do this the same way you would in a stand-alone script. Create the variable pattern in the login in script and name the variable. Save the login script and open the other script and select the parameter where you need the value. Set the parameter value to {{variableNameFromLogin}} (Variables are transferred from one script to the next in a UDP).
I hope this makes sense

Dynamic variable Time for Select

Hi,
I try to develop some scripts but always I have the same problem , when I try to put in a Select instruction the variable Time, it doesn´t work correctly (for example):
*SELECT(%example%,"ID","TIME","[ID]='%TIME_SET%' ")
It doesn´t read correctly the variable Time_Set.
Have you got any idea to try to do selects using dynamic variable?
Thanks for all.

Hi,
Dynamic variables like %TIME_SET% do not interact very well with the compiled default logic (LGX files) when it is run after a data send. If you look at the Default.LGX file, you will notice that your *SELECT statement does not appear there because that *SELECT statement has already been compiled. That is why the logic works when it is run via the debugger (because the LGF file is getting executed at run time) and it does not work when it is run via a data send (because the LGX is being executed).
What you will need to do is:
1. Create a another logic file (for example: Calculation1.LGF) and copy the text from the Default.LGF to this new logic file.
2. Place the following text in the Default.LGF file:
*RUNLOGIC
*LOGIC=Calculation1.LGF
*ENDRUNLOGIC
3. Validate and save the Default.LGF file
Now try running the logic after a data send and see if that works.
Good luck,
John

IMPORT <fs> to tmp_var from database vari(va) id st_key.
endloop.
I do not get any value to tmp_var. Need help!

Try this.
loop at objects.
IMPORT (objects-name) to tmp_var from database vari(va) id st_key.
endloop.
Does it work?

Order by dynamic variable

Hello,
I am trying to sort my query based on a dynamic variable p_sorton in the cursor as follows:
function getMarketView2(

p_fromrow in integer,
p_torow in integer,
p_appTZ in char,
p_calcTZ in char,
p_sorton in varchar2) return varchar2 as
type t_ticket_trade is ref cursor return ex_ticket_trade%rowtype;
v_return varchar2(32767);
v_return_integer integer;
v_String varchar2(32767);
v_ex_ticket_trade_obj ex_ticket_trade_obj;
v_rowcount integer:=0;
v_rowtotal integer:=0;
v_done boolean:=false;
v_sysdate date:=NEW_TIME(SYSDATE,trim(p_appTZ),trim(p_calcTZ));
cursor cur_ticket_trade_event_open (p_event_id in ex_event.event_id%type, v_sysdate in date) is

and (ex_ticket_trade.ticket_trade_status in ('F','A','AB'))
and (ex_ticket_trade.ticket_suite_code='N' OR ex_ticket_trade.ticket_suite_code='Y')
order by p_sorton desc;
--ex_ticket_trade.ticket_datetime desc;
........then comes the rest of the code........
This code compiles fine but does not use the value passed in the param p_sorton in the order by clause.
the same code works fine when hardcoded to "ex_ticket_trade.ticket_datetime"
No idea where I may be going wrong?
Also can I do anything like ORDER BY v1 v2
where v1 specifies columns to sort on and v2 asc/desc, coz that's what I really need to do?
Pls help ...

Dynamic Variable In a Type Definition

Can someone tell me how to define and use a dynamic variable, which resides in a Type Definition. I.E...
Type: beg of type1,
        field 1 type c,
        field 2 <---this dynamic
        field 3 type c.
      end of type1.
Can this be done in Netweaver 2004. And if so, can you show me how?
Thanks for your time.
Kind Regards,
Jason

Don't think it is available now, but I do believe they are working on this for a future release.

Dynamic variable value based on a value from xml

I have a invoice template and it is for 4 different companies in my organization. Based on the organization I need to have a different value for a variable that adds blank lines to the end of the invoice. Is there anyway to assign a value to variable based on the value of a xml tag.
Thanks

I should have explained better before. I have one invoice template and we want to keep it one template for all companies. Each invoice is run individually, each companies footer is different, I am calling multiple headers and footers based on each company. Since the headers and footers are different I need to be able to add different amounts of lines and the end of each invoice depending on that company. I have accounted for the page break in my logic based on the amount lines the page is long. I just need a dynamic variable that I can assign different values on the fly.
Thanks

Dynamic variable and/or XML LazyLoader HELP

I am loading images via xml lazyloader into my air app
I need var b to be "img" + item.id dynamically
any ideas???
for each (var item : LoadingItem in lazy.items)
var b : Bitmap = lazy.getBitmap(item.id);
addChild(b);
If you dont know the lazyloader code then can you please explain how to create a dynamic variable for a bitmap???

so i should set type here
var img:bitmap = {}
then create the variable like this in my for statement?
img[this[item.id]] = lazy.getBitmap(item.id);
lets say item was 1,2,3
Then
img[1]
img[2]
img[3]
would be able to hold a different bitmap
thanks in advanced

Creating dynamic variable names

I know there has got to a way to do this but I am not finding anything on google. I want to create a dynamic variable name like name + i so when your in a loop the names come out name1, name2 and so on till however many you want. I have tried
int name + i = 3;
int name[i] = 3; // which obviously won't but I had to try
int name{i} = 3;and I am out of ideas. Thanks for all your help.

I'd suggest using variables named j or x when posting code which uses them as array indexes.
[i] - is for italics formatting
[u] - is for underlined formatting
[code] is for class Example { ... } code formatting
etc.

Dynamic Variable Names

Okay, I just need to figure out how to make dynamic variable
names. In this case, I have a loop, and inside the loop I need to
create a new array for every iteration of the loop. Something like
<cfloop from="0" to="10" index="i">
<cfset LoopArray#i# = Some Value>
</cfloop>
But that doesn't work. How can you make dynamic variable
named? I think it's probably something to do with evaluate or DE,
but I don't know how to use them, and the livedocs make no sense to
me. Thanks!

From your values, you don't want a two-dimensional array
(which although
you're actually building LinkResults as a struct, with the
sequential
numeric keys, it's basically an array), you want an array of
structs, eg:
LinkResults
.player1.moveId
LinkResults.player1.damage
What is "i" actually counting through? IE: from 1-3 things...
which are...
what?

Dynamic Variable Names in OpenScript

Is there a way to use dynamic variable names? What I mean by this is that the variable name in the file could be:
Name1, Name2, Name3, etc.
I may want to loop through these by saying something like:
For i = 0; i < iLoop; i++
String sFieldName = "{{ViewList.Name" + Integer.toString(i) + "}}";
JOptionPane.showMessageDialog(null, "sFieldName: " + "{{ViewList.{{sFieldName}}}}");
I don't want it to use the literal string of {{ViewList.Name1}}, but rather, I want to use the value from the DataBank for Name1. Thanks.
-John

Nishanth,
Thanks for your suggestion. Unfortunately, this is not a simple variable replacement. I want the name of the variable to be dynamic in nature. Imagine that I have 5 variables in the files named:
Name
FoodPref1
FoodPref2
FoodPref3
FoodPref4
I would like to loop through these and construct the variable name dynamically so it would be something similar to:
for i=1 to 4; i++
sFoodPrefVar = "FoodPref" + i;
getVariables().set("FoodPref",sFoodPrefVar);
JOptionPane.showMessageDialog(null, "Your Food Pref is: " + {{FoodPref}} + "\n");
This is pseudo code, but it would theoretically loop through the 4 food preferences. Thanks.

Dynamic variable names and invalid_character_err

I'm neither an expert at structure notation nor dynamic
variable naming conventions and would appreciate any help with the
following. Thanks!
This code works fine.
<cfset idx="123">
<cfset form.product[idx]=StructNew()>
<cfparam name="form.product[idx].product_nm"
default="Raspberry Jam">
<cfform name="data_entry" method="post" format="flash"
height="525" width="675" action="formdump.cfm">
<cfformgroup type="tabnavigator" height="400"
width="650">
<cfformgroup type="page" label="Product #idx#">
<cfinput name="static_form_name" type="text"
label="Product" value="#form.product[idx].product_nm#" height="350"
width="600" readonly="yes">
</cfformgroup>
</cfformgroup>
</cfform>
The following code results in the following error:
"ORG.W3C.DOM.DOMEXCEPTION ERROR. Message: INVALID_CHARACTER_ERR: An
invalid or illegal XML character is specified." The only change is
in the "name" attribute of the <cfinput> tag:
<cfset idx="123">
<cfset form.product[idx]=StructNew()>
<cfparam name="form.product[idx].product_nm"
default="Raspberry Jam">

Thanks for the info. Knowing what WON’T work is
helpful!
Here’s what I’m trying to do. I’m rewriting
one of my apps, switching out conventional HTML form controls for
<cfform> controls in Flash format. Many of the existing forms
in my app are for updating data contained in a central database.
When such a form is rendered to the screen, each form control is
pre-populated with existing data. All form controls are named
dynamically based upon the unique ID of the record being updated.
Here’s a streamlined but typical example:

<cfquery name="get_project_detail"
datasource="#application.DataSource#">
SELECT project_oid_nbr, project_nm
FROM project_table
WHERE project_oid_nbr IN (14,15,16,17)
ORDER BY project_oid_nbr
</cfquery>

<cfloop query="get_project_detail">
<cfparam name="form.project_nm_#project_oid_nbr#"
default="#get_project_detail.project_nm#">
</cfloop>

<table>
<cfloop query="get_project_detail">
<tr>
<td>
<cfoutput>
Project #project_oid_nbr#:
<input type="text" name="project_nm_#project_oid_nbr#"
value="#Evaluate("form.project_nm_#project_oid_nbr#")#">
</cfoutput>
</td>
</tr>
</cfloop>
</table>
This has been working just fine. However, I’m wondering
if using the Evaluate() function is the most efficient way to go.
Therefore I wanted to use structure notation to avoid the
Evaluate() function, but as mentioned in my original post, this
naming convention won’t work with <cfform> tags.
Any suggestions as to the most efficient way to get the same
result while still using <cfform> tags? Thanks so much!

Dynamic variable for 0CALDAY

Hi all, this is my scenario:
I've created a query with input variable for characteristic Year/Month (0CALMONTH), in columns i added a key figure and in rows i added the characteristic 0CALDAY. The result looks someting like this:
Varibale entry: 09.2006
Result table:
<b>
0CALDAY | KYF</b>
01.09.2006 | 1,000
02.09.2006 | 2,000
03.09.2006 | 1,500
30.09.2006 | 2,100
31.09.2006 | 2,350
Now, what i need is to add a column that shows the value of the previous day, so the result should be:
Varibale entry: 09.2006
Result table:
<b>
0CALDAY | KYF | Previous Day KYF</b>
01.09.2006 | 1,000 | -
02.09.2006 | 2,000 | 1,000
03.09.2006 | 1,500 | 2,000
30.09.2006 | 2,100 | (value for 29.09.2006)
31.09.2006 | 2,350 | 2,350
I guess offsets will be the solution, but i need a variable (dynamic variable) to read the current day (0CALDAY) in the report... anyone knows how to do this? a customer exit can solve it (which code)? Please advice.
Thank you.

Thank you KJ for your answer, but unfortunatelly my knowledge in ABAP is very limited, ¿Do you happen to have an example so i can see how to customize it in order to read values from characteristic 0CALDAY?
