Dynamic returntype in CFC function?

Is there a way to dynamically set a function returntype in a CFC?
For example; if I have a function that contains a 700 line query, and need it to work with two different objects, each of which requires a different format..
.. instead of having two 700+ line functions, one to return a query and the other to return a struct, is there a way to tell the function which format to return the data in? Can it be passed using CFARGUMENT?
Thanks,
^_^

Is there a way to dynamically set a function returntype in a CFC?
It looks like your requirement here has changed anyhow, but to answer the question you actually asked: no, this is not possible. The returntype is needed at compile time, whereas any dynamic determination is done at runtime, after the code is already compiled.
For example; if I have a function that contains a 700 line query,
Really? Ye gods. How?
and need it to work with two different objects, each of which requires a different format..
As Dan said: have two functions. One which returns the query, one which calls that function, messes with it, and returns a struct.
Someone suggested using returntype="any", and whilst that's possible, having one function which could possibly return two different types of data is... um... "less than ideal". As a rule, a function should do one thing, so having code that either does x or does y is doing two things.

Using Tree Elements as parameters to a CFC function using AJAX

I would like to use a <CFTREEITEM> tag element ("value") as a parameter to a CFC function. I regret that I am fairly new to AJAX and I do not have te exertise to accomplish this. Does anyone have a method? Page 671 of the Coldfusion 8 Developers Guide indicates that it is not posiible to do this "directly", but I am hoping to find a way through possibly less direct means.

Hi kanishka wickrama
Here is an example of passing parameters from SAP to a Stored Procedure:
In the stored procedure you need your variable with the word output as follows:
@FromDate varchar(12) OUTPUT,
@ToDate varchar(12) OUTPUT
Then in your query in SAP pass them as follows (in this example the dates are pulled from OPCH, but you can also use OFPR as it contains all the start and end dates for each financial period)::
DECLARE @FromDate DATETIME
DECLARE @ToDate DATETIME
SELECT @FromDate = T0.DocDate FROM dbo.OPCH T0 WHERE T0.DocDate = '[%0]'
SELECT @ToDate = T1.DocDate FROM dbo.OPCH T1 WHERE T1.DocDate = '[%1]'
EXEC MY_STORED_PROCEDURE @FromDate, @ToDate
Hope this helps
Kind regards

CFC - function not found.

Can anyone see why this is not working? I am pulling my hair

see what is wrong here?? I can't !!
Many thanks in advance for any suggestions.

Not possible to output CFTREEITEM in a CFC function?

Hi there,
I am parsing a sorted list of strings (in the form of a/b/c/,
a/b/c, /a/c/d etc.) and trying to make a treeview out of it.
I have the CFFORM and CFTREE tag in the top function and the
code that generate CFTREEITEM in a subfunction, but I got the
following error:
Context validation error for tag cftreeitem.
The tag must be nested inside a cftree tag.
It seems that ColdFusion doesn't recognize that calling code
is already nested inside a CFTREE tag in the top function. I
extract the code generating CFTREEITEMs to a sub function because
it is called multiple times from different context, it would be a
lot of hassle and quite stupid to "inline" it.
If what I am trying is, for whatever reason, not possible,
would it be possible then to have the sub function generate the
code into a string and somehow dynamically evaluate that?
Any hints or tips will be greatly appreciated!

Dynamic return from a function based on an argument

I have a function that I am using to output a nested list of
child/parent relationships
the function works wonderfully except that i want to be able
to change the way the list is displayed depending on an argument
being passed
i want the list to be displayed twice on the same page, one
with output in a table, and one with output in a drop down box
i thought the easiest way would be to create an argument that
can be used in IF statements
look at my code below
quote:

<cfparam name="output" default="">
<cfparam name="catNameOutput" default="">
<cfparam name="indent" default="">
<cffunction name="GenerateCategories" access="public"
returntype="string">

<cfargument name="GenCatParent" type="uuid"
required="yes" default=0 >

<cfargument name="level" type="numeric" required="yes"
default=0 >

<cfargument name="output_type" type="numeric"
required="yes" default=0 >

<cfquery name="rsCategoryChildren"
datasource="webdsn">
SELECT * FROM dbo.BlogCategories
WHERE catParent = '#GenCatParent#'
ORDER BY catName ASC
</cfquery>
<cfloop query="rsCategoryChildren">

<cfloop from="0" to="#arguments.level#" index="i">
<cfset indent = indent & " ">
</cfloop>

<cfif arguments.output_type EQ 1>
<cfset catNameOutput = "<option value='" & catPK
& "'>" & indent & Trim(catName) &
"</option>">
</cfif>

<cfif arguments.output_type EQ 2>
<cfset catNameOutput = "<tr>
<td>edit</td> <td>delete</td> <td>"
& indent & Trim(catName) & "</td>
</tr>">
</cfif>
<cfset output = output & catNameOutput>

<cfset indent = "">

<cfquery name="checkForKids" datasource="webdsn">
SELECT * FROM dbo.BlogCategories
WHERE catParent = '#rsCategoryChildren.catPK#'
ORDER BY catName ASC
</cfquery>

<cfif checkForKids.recordcount GT 0>
<cfset GenerateCategories(genCatParent=catPK, level =
level +1, output_type = arguments.output_type)>
</cfif>
</cfloop>
<cfreturn output>
</cffunction>
<cfquery name="rsCategoryParents" datasource="webdsn">
SELECT * FROM dbo.BlogCategories
WHERE catParent IS NULL
ORDER BY catName ASC
</cfquery>
and here is how i am calling the function for each situation
(the table and the dropdown):
quote:
<table width="100%" class="managementtable">
<tr bgcolor="#F6F6F6">
<td> </td>
<td> </td>
<td>Category Name</td>
</tr>
<cfloop query="rsCategoryParents">
<cfoutput><tr> <td>edit</td>
<td>delete</td> <td>#Trim(catName)#</td>
</tr></cfoutput>
<cfset recursivecats =
GenerateCategories(genCatParent=catPK,level=0,output_type=2)>
<cfoutput>#recursivecats#</cfoutput>
</cfloop>
</table>

<select name="select">
<option>None</option>
<cfoutput query="rsCategoryParents">
<option value="#catPK#">#Trim(catName)#</option>
<cfset recursivecats =
GenerateCategories(genCatParent=catPK,level=0,output_type=1)>
#recursivecats#
</cfoutput>
</select>
calling the function for the table and the dropdown on the
same page does not work
if the function is first called with the argument for table,
it tries to also output the table formatted code when the function
is called again (even if it is called again with the argument for
dropdown)
is there another way i can have the same function output two
different sets of data based on an argument? what am i doing wrong
thanks for your time

sjlsam2,
Yeah, I think the main problem you had was a scoping one. For
the second function call, the output variable already contained all
of the output code from the first function call. In fact, I
wouldn't be surprised to find that the output string for the second
function call contained the output of the first plus the output of
the second, and that it didn't render correctly on screen. A
View Source would have determined that.
Anyhow, I suggest that you VAR your output variable as
cf_dev2 suggests, and delete the three CFParam lines at the top.
Further, your recursive call would therefore need to return it's
result to the output variable, thus completing the recursive loop.
See below:

<cfargument name="output_type" type="numeric"
required="yes" default=0 >
<CFSet Var Output = "">
<CFSet Var catNameOutput = "">
<CFSet Var indent= RepeatString(" ",
Arguments.Level)>

<cfquery name="rsCategoryChildren" datasource="webdsn">
SELECT * FROM dbo.BlogCategories
and

<cfif checkForKids.recordcount GT 0>
<cfset
Output = Output & GenerateCategories(genCatParent=catPK,
level = level +1, output_type = arguments.output_type)>
</cfif>
</cfloop>
This is what I suggest with your code. HTH :)

Set label of an item dynamically through pl/sql function

Hi ,
How Can I get the label of an item dynamically through a pl/sql function.
I have a table that stores the label name for these items.
I want to set the label for the item based on the value in my table ?
Is it possible ?
any ideas ?
Thanks in advance,
Dippy

If I understand you correctly, you are using a standard report region, but want to dynamically name the column headers? The only way I've been able to get this to work is to create hidden items for each column header, calculate the value you want for each item, then reference the item in the column header using &item_X. for the column header name.
The problem is that at this point, APEX doesn't allow for dynamic column naming unless you want to do everything yourself using a PL/SQL process that builds the report table manually. I've done that for certain complex reporting tools.
I understand it's tedious to create all the column header items; I have one report that has over 72 items used in this way. It was a pain, but it got the job done.

Dynamic Internal Table in Function Module

Hi,
I am developing a function module which is similar to GUI_DOWNLOAD. So , In My function module I would like to pass the internal table dynamically.I saw the paramter DATA_TAB in the function module GUI_DOWNLOAD. But there is no type associated with that. Could anyone help Me out for achieving thsi fucntionality.
Regards
Elini.P

Hi Elini,
When the tables parameter of the function module has got no line type specified, it will acquire the same type as the parameter that is passed to it during the call. In other words, the table is of generic type. you can pass any table to that parameter.
However, in case your function module is Remote Enabled, you will not be able to define the tables parameter as generic. IOt must be given some line type.

Anand Mandalika.

Defining Dynamic structure in Remote Function module(RFC)

Team,
I got a requirement, where I need to create a dynamic structure and dynamic table in the exporting tab of Function module(RFC).
Say, I have sales request(4 fields) and sales quotation(5 fields).
Depending on the importing parameter, If it sales request I need to export 4 fields as a structure and if in the importing parameter it is sales quotation then I need to pass 5 fields as a structure.
Any help please??
Thanks,

Passing multiple dynamic params to JS function

Hi,
I have a problem that I have been grappling with for some time now.
My JSP shows the user a list of textboxes dynamically, depending on a value from the DB. So, if the field value is 10, the user will see 10 textbixes and they will sequentially be assigned names as - text1, text2.....
The problem arises when I try to pass the values of these textboxes to a JS function. Now, my function does not know how many params to expect, so I am trying to send it as a single string separated by : (colon).
My method call looks like this -
<input type="button" value="Click Here" style="width:140px;"
               onClick="myJSFunction(
<c:forEach var="item" items='${sessionScope.textFields}' varStatus="status">
          document.form.text<c:out value='${status.count}'/>.value+':'
                    </c:forEach>
                    );">
Pls. note that I am putting the colon at the end of every call in the forEach loop.
I get a syntax error if I run this code for more than 1 textbox. The compiler expects a closing bracket ) at the end of the last line, which I have already provided.
Is there any other way to do this or is there anything obviously wrong with my code?
Thanks in advance.

There are several ways around it.
javascript can have any number of parameters passed to a function.
You don't even have to declare them.
You can reference them as arguments[0], arguments[1], arguments[2]...
Another suggestion: pass up the "basename" and a count of how many fields there are and use the "eval" function
var base = "document.myform.text";
for (var i = 0; i<numFields; i++){
var value = eval(base + i + ".value");
}or something like that (sorry don't have time to check it right now)

How to pass dynamic logical expression to function module

Hi,
I'm using FM META_READ_TABLE as below:
As mentioned above im using META_READ_TABLE FM to get company codes from CSKS table of ECC. Below is the code im using:
   DATA:i_opt type STANDARD TABLE OF RFC_DB_OPT, i_fld type STANDARD TABLE OF RFC_DB_FLD,
       i_res type STANDARD TABLE OF TAB512.
Constants:   c_expr(72) TYPE c VALUE 'KOSTL EQ COST_CTR', c_fld(5) TYPE c VALUE 'BUKRS'.
w_opt-text = c_expr.
w_fld-FIELDNAME = c_fld.
append: w_opt to i_opt,
        w_fld to i_fld.
data i_control type STANDARD TABLE OF BBP_CONTROL_RECORD.
**&&--Get Co code from ECC (CSKS table)
CALL FUNCTION 'META_READ_TABLE'
EXPORTING
    QUERY_TABLE          = c_table
*   DELIMITER            = ' '
*   NO_DATA              = ' '
*   ROWSKIPS             = '0'
*   ROWCOUNT             = '0'
    LOGICAL_SYSTEM       = v1_logsys

    OPTIONS              = i_opt
    FIELDS               = i_fld
    DATA                 = i_res
    CONTROL_RECORD       = i_control.
however it is giving me 'Communication Error' while executing this piece of code. I guess the problem here is with passing query to i_opt table. obviously the way im doing this is wrong and it has to be dynamic. Could anybody please give me idea how to execute fm with dynamic query i.e., 'KOSTL EQ COST_CTR' where COST_CTR is cost center and an importing parameter to this.please advise.
Rgds

The "communication error" would seem more likely to be a problem with an RFC call - does 'META_READ_TABLE" call another function in the remote system?
We don't have that function module here (is it SRM?) but you should be able to construct your dynamic "where" something like this (p_kostl is the variable in this example):
data:
    l_where     type text72.
concatenate
    'KOSTL EQ_'
    p_kostl      "variable
    into l_where.
translate l_where using '_ '. "replace underscore with space

Hi,
When this function module CALL FUNCTION LT_TRWPR-FUNCTION is called, it automatically goes into a Z_XXXXXXXXX function module.
This function module is called in all transactions where financial postings could happen, however to be precise i would say at the time of Vendor invoice postings.

to explain this, is there anyone know the reason caused this
issue????
Thanks!

Have you checked the logs to see what (if anything) else is
being reported
back about this?
Can you check what's going on on the Oracle - am guessing
it's Oracle from
the "CONNECT BY PRIOR" - box @ the time? I presume you can
set it to log
all SQL or JDBC activity?
Are you certain (absolutely ~) that arguments.jpRunNum
contains 32144809,
for the purposes of the test that's failing?
What if you factor the query out into a CF template and run
these tests:
1) as is in your example
2) change 32144809 to use a <cfqueryparam>, but still
hard code the value
to 32144809.
3) set a variable to 32144809, and use the variable as the
value of the
parameter.
From what you're describing, it seems like your query is
getting in a loop,
which with this sort of thing can be down to giving the
CONNECT BY PRIOR a
bung value.

yes, you can use the textfield properties for this.
