Dynamic Array Names

That's fairly complex to explain, so forgive me if I miss some details.
I got a code working for Coldfusion 9, but my host only uses Coldfusion 8, and I'm not in any position to change that (or to change host for that matter).
Now, I've a recipe list, users are able to choose one or several of the recipes and can add it to the "Grocery List", said grocery list is generated from the ingredients of the recipe. It starts out as any "shopping cart" application out there, however following the various tutorials on the subjet I always get stuck in getting the "Ingredients list", these tutorials allow to pass one variable, and hardly anything else.
Furthermore that list may be printed or downloaded via .txt file (to put on my phone), so I need to keep the data.
As explained above whatever I came up with does not work under CF8, so far I modified my code for what follows (note, I know that the "Evalute()" does not receive much love, so I tried to remove them, the ones I left are only because no matter what else I tried it did not work) :
<cfoutput>
 
 <cfloop from="1" to="#arraylen(arList)#" index="counter">
 
 #arList[counter].Nom.getNom()#</th>
 
 <cfif not isdefined ("session.I_#counter#") OR ArrayIsEmpty (Evaluate("session.I_#counter#")) >

 <cfinvoke component="cfc.manoire" method="Display_Ingrid" returnvariable="Display_Ingrid">
 <cfinvokeargument name="M_ID" value="#arList[counter].Nom.getM_id()#">
 </cfinvoke>
 
 <cfset VARIABLES["session.I_" & counter] = ArrayNew(1)>
 
 <cfloop query="Display_ingrid">
 <cfset Arrayappend(VARIABLES["session.I_" & counter], structnew())>
 <cfset position=arraylen(VARIABLES["session.I_" & counter])>
 <cfset VARIABLES["session.I_" & counter][position].I_Nom = #I_Nom#>
 <cfset VARIABLES["session.I_" & counter][position].Quantite = #Quantite#>
 <cfset VARIABLES["session.I_" & counter][position].Unite = #Unite#>
 </cfloop>
 </cfif>
 
 <cfloop from="1" to="#Arraylen(Evaluate('session.I_#counter#'))#" index="val">
 #VARIABLES["session.I_" & counter][val].I_Nom#
 #VARIABLES["session.I_" & counter][val].Quantite#
 #VARIABLES ["session.I_" & counter][val].Unite#
 </cfloop>
 </cfloop>
 </cfoutput>
I get a" Element session.I_1 is undefined in a Java object of type class coldfusion.runtime.VariableScope" at the beginning of the last loop.
I've tried with evaluate() and it has a problem starting [val], that's not something I found to be fairly well documented so I guess there must be something fairly simple and straightforward that completely escaped me.
I'm not set in any direction, so any advice and/or constructive criticism is/are welcome.
Thanks

I don't have a means to test any of this right now ( i am on vacation), but I thought I would take a moment to point out that an easier, and cleaner way to access the variables in the session scope dynamically is:
<cfset session["I_#counter#"][position].I_nom = "" />
Same with your ArrayIsEmpty() statement.
ArrayIsEmpty (session["I_#counter#"])
Could you indicate which of the above lines is actually erroring?

How to pass dynamically generated string value as array name in TestStand?

Hi All,
I have a string variable which holds an array name as its value. The string value is a dynamically generated one. Now my problem is how to retrieve the values within the array where as the array name is stored in a string variable.
for eg:
fileglobals.InfoName = "Array_Name" --> fileglobals.InfoName is a string variable, Array_Name is the array name generated dynamically and it is known only at run-time.
Array_Name[0] = "a";
Array_Name[1] = "b";
Array_Name[2] = "c";
In the above case, I have to retrieve the values of a, b and c
Any help is greatly appreciated
Thanks

Hi,
Looking at your sequencefile.
You seem to be trying to save into FlieGlobals.InfoName a string with the values of "FileGlobals.Info_0".."FileGlobals.Info_n" where n is the value of Parameter.TestSocket.Index.
Then you are setting the value into FileGlobals.TempName from "StationGlobals.FileGlobals.Info_0" assuming Parameter.TestSocket.Index is 0.
Is this correct?
I realise this is a cutdown sequence file but you must make sure These variable actually exist in either FileGlobals or StationGlobals. Also with FileGlobals each SequenceFile has its own FileGlobals unless you have set the properties of the SequencFile to use a common FileGlobals.
What was the precise error you was seeing as it will properly telling you what variable of property it can't find.

How to change recordset bahaviour to accept dynamic column names in the where clause

Hi
im using php-mysql and i make a recordset and i want to make the column names in the where clause to be dynamic like
"select id,name from mytable where $tablename-$myvar";
but when i do this my i break the recordset and it disappear
and when i use variables from advanced recordset it only dynamic for the value of the column not for the column name
and when i write the column name to dynamic as above by hand it truns a red exclamation mark on the server behaviour panel
so i think the only way is to change the recordset behaviour is it? if so How to make it accept dynamic column names?
thanks in advance.

As bregent has already explained to you, customizing the recordset code will result in Dreamweaver no longer recognizing the server behavior. This isn't a problem, but it does mean that you need to lay out your dynamic text with the Bindings panel before making any changes. Once you have changed the recordset code, the Bindings panel will no longer recognize the recordset fields.
Using a variable to choose a column name is quite simple, but you need to take some security measures to ensure that the value passed through the query string isn't attempting SQL injection. An effective way of doing this is to create an array of acceptable column names, and check that the value matches.
// create array of acceptable values
$valid = array('column_name1', 'column_name2', 'column_name3');
// if the query string contains an acceptable column name, use it
if (isset($_GET['colname']) && in_array($_GET['colname'], $valid)) {
$col = $GET['colname'];
} else {
// set a default value if the submitted one was invalid
$col = 'column_name1'
You can then use $col directly in the SQL query.

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?

Creating a dynamic Array

Thanks for reply.
I want to create a dynamic array and for this I used ArrayList Collection and Vector Class. I am using JDK 1.4.1 . But , I have a problem in that. In ArrayList, I used the following code:
ArrayList al = new ArrayList();
while(rs.next())
al.add(rs.getString("Enter_Year"));
al.add(rs.getString("UG_Production_Mi_Te"));
al.add(rs.getString("OC_Production_Mi_Te"));
al.add(rs.getString("Total_Production_Mi_Te"));
al.add(rs.getString("OBR_MM3"));
al.add(rs.getString("OMS_Te"));
al.add(rs.getString("Coal_Offtake_Mi_Te"));
al.add(rs.getString("Supply_to_Steel_Plant_Th_Te"));
al.add(rs.getString("Royalty_SalesTax_MP_Crs"));
al.add(rs.getString("Royalty_SalesTax_CG_Crs"));
al.add(rs.getString("Total_ManPower"));
al.add(rs.getString("Fatality_Rate_per_Mi_Te_Output"));
al.add(rs.getString("Total_Wellfare_Expenditure_Crs"));
String rpt[][] = new String[al.size()][];
rpt = al.toArray(rpt); // ArrayStoreExecption error
String colheads[] = {"...........My Table's Column names are here....."};
JTable table = new JTable(rpt,colheads);
JScrollPane jsp = new JScrollPane(table);
add(jsp);
At the statement having comment line I received the error ArrayStoreException. The JTable accepts the 2 D array for storing the info and I think the toArray() method is not working there and can't convert the ArrayList elements into an Array. Similarily, Vector Class is also not converting the elements into an array object and showing the same error only.
Please help me to convert it into an array object so that I can pass it into the JTable argument.

That isn't a jdbc problem but rather a collection problem.
You certainly can't convert a one dimensional collection into a two dimensional array automatically. And that is what you are creating with the while loop.
Since you know the column names you also know the inner array size so you can start by creating a statically sized string array (not collection) in the loop and add that to the outer collection. That might solve the problem.

Dynamic file name from input payload (RFC 2 flat file)

Hi,
I have an RFC to flat file scenario. The output flat file has not an XML structure, it's just a plain text file generated with abap mapping.
In my source interface (RFC), I have a field called <FILENAME>, I want to use the value of that field to create the target file using dynamic file name. But if in variable substitution I use payload:ZRFC_NAME,1,FILENAME,1 It doesn't work because the dynamic variable substitution try to access to output payload, not the source one...
What can I do?

Hi Marshal,
You can add a extra node to your target strucutre like
FileName- Node
--FileName - Element.
do the mapping from the field filename of RFC to FileName field in u r target strucure. And use this field path at Refrence in variable subtituion.
In the Content converison add the Name & Values as below
FileName.fileldNames -- FileName
FileName.fieldFixedLengths -- 0
FileName.fixedLengthTooShortHandling -- Cut
So the extra field in u r target structure would not populate in u r target text file.
Cheers

Saving result from sp_executesql into a variable and using dynamic column name - getting error "Error converting data type varchar to numeric"

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:

>> I need to select from a dynamic column name and save the result in a variable, but seem to be having trouble with the values being fed to sp_executesql <<
This is so very, very wrong! A column is an attribute of an entity. The idea that you are so screwed up that you have no idea if you want
the shoe size, the phone number or something else at run time of this entity.
In Software Engineering we have a principle called cohesion that says a model should do one and only one task, have one and only one entry point, and one and only one exit point.
Hey, on a scale from 1 to 10, what color is your favorite letter of the alphabet? Yes, your mindset is that level of sillyity and absurdity.
Do you know that SQL is a declarative language? This family of languages does not use local variables!
Now think about “month_val” and what it means. A month is a temporal unit of measurement, so this is as silly as saying “liter_val” in your code. Why did you use “sp_” on a procedure? It has special meaning in T-SQL.
Think about how silly this is:
SET @month_val = 'Month' + CAST(@month_nbr AS VARCHAR(2));
We do not do display formatting in a query. This is a violation of at the tiered architecture principle. We have a presentation layer. But more than that, the INTERVAL temporal data type is a {year-month} and never just a month. This is fundamental.
We need to see the DDL so we can re-write this mess. Want to fix it or not?

but thats what you get when a company throws you in at the deep end with a ridiculous time constraint to migrate a whole MSSQL DB.Migrating SQL-Server to Oracle is not a simple thing. A lot of best practices in SQL-Server are absolutely worse practices in Oracle - they are that different. Simple example is lock escalation - an issue in SQL-Server. In Oracle, the concept of a lock being escalated into a page lock simply does not exist.
In terms of getting the migration done as quickly and painlessly as possible I try to reuse all the logic as it appears in the MSSQL code - in this case it was using dynamic table names. I do not doubt that i am probably shooting myself in the foot in the long run.....As long as you do not splatter too much blood on us here.. not a problem :D
Seriously though - just keep in mind that what works in SQL-Server may not work as well (or even at all) in Oracle. So do not hesitate to refactor (from design to code to SQL) mercilessly when you think it is warranted.

Dynamic file name ?

Hi,
I am following this blog to name the target file/directory dynamically at the runtime :

Hi,
Try following this weblog for dynamic file name.
/people/michal.krawczyk2/blog/2005/11/10/xi-the-same-filename-from-a-sender-to-a-receiver-file-adapter--sp14
Dynamic filename come under the Dynamic configuration in moni, for your messages.
This is the code used inside.

That is why Dynamic configuration is coming in output.. It is a class to generate dynamic configuration file at runtime provided by SAP XI.

Dynamic file name in case of .txt output files

Hi all,
I have a query related to dynamic file name scenario.
In case of IDOC-XI-FILE sceanrio,
Is it possible to generate .txt file name based on Plant number like
%<Plantname>%_%<BusinessDay>_filename.txt
Note:I have implemneted this for .xml output files but I am not able to implement it for .txt output files .
PLEASE HELP ME .

Prabhat

Hi Prabhat,
I think, the normal Dynamic File Name generation should work fine in your case also. Even if you perform Content Conversion, you can use Variable Name Substiution to create your Destination file name as, the name of the file is determined first and only then is the content converison perfromed.
for info on content conversion, I would suggest that you go through this thread and check my reply,

Dynamic File name in File Adapter

Hi,
I have a requirement to pass dynamic file name in File Adapter.
Is there any way to pass a variable for the file name attribut in file adapter.
I am looking for some options apart from %yyMMddHHmmss%,%SEQ%...etc
Please suggest if any of you have information on how to put values from a variable to file name attribute in file adapter
regards
Saiju

Hi Saiju,
Yes there is.
Assign your file name to a variable, let's say 'fileName'.
Now go to your invoke activity(for the specific fileadapter) -> Property tab-> find a property call jca.file.FileName -> in the value field assign 'fileName' variable.
That's it... (assuming you are using 11g)
