CFScript Math expression - Summing up looped over data
If I loop over numeric data and I want to sum that data I am looking for the correct manner to do so. Of course I want to do this in cfscript.
I know that I could go the route of doing a one demensional array and using the array sum function and I could also use stauctures.
I am interested in different solutions to this problem.
My end state is that I need to sum and average looped dynamic data for reporting purposes.
For purposes of example static values will be helpful for better understanding.
Thanks in advance.
Owain,
This is what I came up with and it outputs the looped data. Now I am trying to add it up and average the results.
BTW Adam,
Be delusional on a Microsoft or Oracle forum board.
Now that would be some fun reading cutting through those flames! (In a patronising Kinda Way!).

I have returned a dataset and one of the fields from the
dataset is a comma delimited list, is there a way to loop over this
list and display the values.Hi Martin,
you assign the VARC incorrectly.
L_ACC = VARC(VACVTE01).
should be
L_OBSERV = VARC(VACVTE01).

Looping over arraycollection with sap data
Hello,
I asked a lot of persons but i still have a problem.
I am trying to make a organizational chart in Adobe Flex with data out of the SAP system.
When I try to access my data that I have given trough the Flash Islands container it doesn’t work.
I do:
[Bindable]
Public var datasource:Arraycollection;
Then I want to loop over this datasource with a for loop but it says that the object is null.
for (i = o; i < datasource.length; i++)
When I use datasource as dataprovider for a datagrid in Flex, that works perfect.
Please answer fast because I need it for school.

I need sum of rows based on month. I have tried following syntax. It did not work, which is returning $0. Appreciate any help i get.
=sum(iif(Date.value>="8/01/2010" AND Date.value<="8/30/2010",Total.value,0))Hi RG K,
According to your description, you want to calculate sum of total based on month use expression, but the expression does not work. If that is the case, please refer to the following steps:
In design surface, right-click Insert and click Text Box.
Right-click inside of the text box, then click expression.
In Expression text box, type the expression like below:
=sum(iif(Fields!Date.Value>="8/01/2010" AND Fields!Date.Value<="8/30/2010",Fields!total.Value,CDec(0)))
In this expression, the data type of total is Decimal, so we need to convert 0 to Decimal use CDec() function. If data type of total is Double, we need to use CDbl() function.
The following screenshot is for your reference:
If you have any more questions, please feel free to ask.
Thanks,

Hello,
I have a foreach loop in SSIS (as part of Visual Studio 10 and with SQL Server 2012).
It loops over all files in a folder (ForEach File Enumerator).
I set the folder: OK
Traverse Sub folders: OK
I have set up a Variable in Variable Mappings called FileName so it shows User::FileName: OK
Index of variable is 0: OK
It almost works ok. Except that the first file it finds is never considered.
I set a breakpoint then and the first file it finds, is shown in black in the watch variable window. All subsequent files found are shown in red font. When I change the names of the files so another file is the first file found then it skips the other one
which now is the first file.
What is going on here? Why does SSIS skip the first file it finds in a foreach file loop?
Any suggestions highly appreciated.
Thank you
Andi
Andreas"red font - interesting, any example to show us (image)
It would be interesting to share with us whether you use any file masks or expressions.

It appears a variable value turns red when it changes between breakpoints. It started black for the first value (the first file, obtained BEFORE the execution reached the breakpoint), and then turned red. I was able to reproduce this behavior on a test environment.
However, it did not skip any files.
OP, please set up the test shown in the image below. Create a breakpoint in the sequence container for the "OnPreExecute" event. -
Problem with Message-Mapping: Loop over Elements possible?
Hi all,
I want do create a Message-Mapping for an IDoc-to-File Scenario. In the Source Structure there are some Elements which can appear more than once (1..unbounded). I need a mechanism which loops over these elements and search for specified values. From the Element which contains an element with this specified value the mapping should write a value in the target structure.
Here a simple example (source structure) for better understanding:
<root>
<invoice>
<number> 10 </number>
<sum> 200.00 </sum>
</invoice>
<invoice>
<number> 20 </number>
<sum> 150.00 </sum>
</invoice>
<invoice>
<number> 30 </number>
<sum> 120.00 </sum>
</invoice>
</root>
Now the duty of the Mapping should be to search in the elements <invoice> for the number 30. And then the sum of the invoice with the number 30 should be written in a field of the target structure.
I tried it out with a constant togehter with an equalsS-function and an ifWithoutElse-function, but it is working only then, if the invoice with the number 30 has the first position in the root context.
Can anybody help me? Thanks
With kind regards
ChristopherHi,
Write a UDF to sum the required values and map to target node.
See while writing the UDF select the type as queue.
number -- removecontext-UDF targetnode
sum----removecontext--/
number abd sum or the two inputs
in UDF
int nsum = 0;
for(int i;i < number.length;i++){
if number(i).equals("30") then
nsum = nsum + valueOf(sum(i));
result.addValue(nsum); // convert the nsum into string

You've got already some suggestions, but the most straightforward way is to run the unhinted statement in both environments and then force the join and access methods you would like to see using hints, in your case probably "USE_HASH(P D)" in your production environment and "FULL(P) FULL(D) USE_NL(P D)" in your development environment should be sufficient to see the costs and estimates returned by the optimizer when using the alternate access and join patterns.
This give you a first indication why the optimizer thinks that the chosen access path seems to be cheaper than the obviously less efficient plan selected in production.
As already mentioned by Hemant using bind variables complicates things a bit since EXPLAIN PLAN is not reliable due to bind variable peeking performed when executing the statement, but not when explaining.
Since you're already on 10g you can get the actual execution plan used for all four variants using DBMS_XPLAN.DISPLAY_CURSOR which tells you more than the TKPROF output in the "Row Source Operation" section regarding the estimates and costs assigned.
Of course the result of your whole exercise might be highly dependent on the actual bind variable value used.
By the way, your statement is questionable in principle since you're querying for the first row of an indeterministic result set. It's not deterministic since you've defined no particular order so depending on the way Oracle executes the statement and the physical storage of your data this query might return different results on different runs.
This is either an indication of a bad design (If the query is supposed to return exactly one row then you don't need the ROWNUM restriction) or an incorrect attempt of a Top 1 query which requires you to specify somehow an order, either by adding a ORDER BY to the statement and wrapping it into an inline view, or e.g. using some analytic functions that allow you specify a RANK by a defined ORDER.
This is an example of how a deterministic Top N query could look like:
SELECT
FROM
SELECT p.*
FROM t1 p, t2 d
WHERE d.emplid = p.id_psoft
AND p.flag_processed = 'N'
AND p.desc_pool = :b1
AND NOT d.name LIKE '%DUPLICATE%'
ORDER BY <order_criteria>

I have two queries. One is a main query that we pull from a form submission. The second is a small query resultset that lists different subgroups in my company and what main group they belong to. I pull several QoQ from the main query. In the main query results, there is a column that holds the subgroup information. I am trying to do a Q0Q where I group the data from the main query into the main groups for analysis. Here is an example...
Main Query
record 1 - subgroup 1
record 2 - subgroup 2
record 3 - subgroup 3
Second Query
Subgroup 1 - Main Group 1
Subgroup 2 - Main Group 2
Subgroup 3 - Main Group 1
So I am trying to loop over a QoQ on the main query where the result set would contain the information only from Main Group 1. So record 2 would be eliminated. I have tried using an IN clause with a cfloop, but I run into syntax trouble with the comma. I also tried looping over the QoQ as a whole and the resulting dump is only the last record.
If there is anything else you need, let me know.
Any thoughts?

Efficient looping over strings
ABAPers,
I need to loop over all the characters in a string. Here is the pseudo code:
data: myData TYPE string.
data: n TYPE i.
data: ch TYPE char1.
n = STRLEN( myData).
DO n TIMES.
ch = myData(sy-index).
ENDDO.
While this code would work, the problem is that I am actually iterating over myData two times. STRLEN itself is internally iterating over myData to compute the length.
Is there a more efficient looping mechanism without going through STRLEN?
Thank you in advance for your help.
PradeepHi,
You can try this when it comes to converting things
WHILE myData IS NOT INITIAL.
do something
ENDIF.
myData = myData+1(*).

Hey Guys,
I have a component that returns a structure. The structure is
called ContactQuery. ContactQuery has to elements, one called
Results, and one called Success. Results contains the data I want
to loop over. If you try looping over the ContactQuery by using
CFLoop and specify the ContactQuery as the collection, of course it
only loops twice (once for Results, once for Success). How can I
loop over the Results structure withing ContactQuery? You can see
the dump of the structure at:
http://www.digitalswordsmen.com/cfschedule/admin/Create_Tokens_Table.cfm
Attached is the code I have. I am just unsure of the syntax
for looping over the Results section of the structure.
Thank you.Nope. I am dumb and didn't really think about it. The fact
that it is a query nested in a structure threw me off. The code
that works was
<cfloop query="ContactQuery.Results">
<tr>
<td></td><td>#firstname#</td><td>#lastname#</td><td>#email#</td><td>#randrange(10000,9999 9)#</td>
</tr>
</cfloop>
Thanks for the help, sorry about that dumb question. -
etings,
I have a query I am pulling that has a date field entitled, "Completed". I am attempting to loop over the query by date to slice and dice the data for a table and chart. Here is what I have done thus far...
Setup two variables where I am only interested in the month. My plan is to fileter the date by month so I can pull the data out by month.
<cfset startDate = #DatePart('m','01/01/09')#>
<cfset endDate = #DatePart('m',Now())#>
Here is my loop...
<cfloop from = "#startDate#" to = "#endDate#" index = "i" step = "1">
Here is one of my QoQs within the loop...
<cfquery name="NPS0" dbtype="query">
SELECT *
FROM rsNPS
WHERE #DatePart('m',rsNPS.completed)# = #i#
</cfquery>
I am having difficulties in getting this to work. Has anyone ever done something like this. I feel like the answer is right in front of me, but I have been staring at this code for a while. If anyone has any thoughts, I would be glad to hear them.

QoQ are a separate beast. You cannot use standard CF functions inside them. AFAIK, QoQ only support a few functions like CAST, UPPER, LOWER, etcetera. So as Dan suggested, you should peform the date functions in your database query. -
Loop over form values & insert into db
Form
prod_id prod_name prod_price prod_status
001 product 001 1.00 1
002 product 002 2.00 1
003 product 003 3.00 0
004 product 004 4.00 0
Form Dump
prod_name product 001,product 002,product 003,product 004
FIELDNAMES prod_id, prod_name, prod_price, prod_status
prod_price 1.00,2.00,3.00,4.00
prod_status 1,1,0,0
prod_id 001,002,003
I want to update a few fields, prod_price and prod_status. I submit these values to my update page but I'm not sure how to loop over these values and update by the prod_id. In my update page I'm using cfdump and I see the structure of the form, the fieldnames as well as the prod_id, prod_name, etc and their values.
My question is how do I loop over these form values so I'll be able to update by each prod_id? I've played around with looping over the form collection values but no luck.When I do stuff like this, I append the "id" value to the end of each form field. That enables me to ensure the other fields match up.
When processing the form, I generally do something like this:
<cfloop list="#form.fieldnames# index="ThisField">
<cfif left(ThisField, 9) is "prod_name">
<cfscript>
ThisID = removechars(thisfield, 9);
ThisName = form["prod_name" & ThisID];
same for other fields
Then do something with those variables. -
Looping over a series of lists created from form fields
generates an error when one of the fields on the form has been left
blank. The form is a list of event dates, start times and end
times. One event can have a number of times.
When the end time is uncertain, we want to leave it blank.
However, doing so shortens the list created from #form.endtime# so
that the lists don't match and there's an error message:
"Invalid list index 2.
In function ListGetAt(list, index [, delimiters]), the value
of index, 2, is not a valid as the first argument (this list has 1
elements). Valid indexes are in the range 1 through the number of
elements in the list."
How do you get around this problem? Tx.yoman,
No need for separate forms. Use a counter to number each
group of field names
<input name="EventDateID1" ...>
<input name="EventDate1" ...>
<input name="EventDateID2" ...>
<input name="EventDate2" ...>
Then loop through the form fields on your action page
<cfloop from="1" to="#form.maxCounter#"
index="counter">
<cfset EventDateID = form["EventDateID#counter#">
<cfset EventDate = form["EventDate#counter#">
... rest of fields
<cfquery name="UpdateFeatures" datasource="#dsn#">
UPDATE EventDates
SET EventDate = '#EventDate#', ....
WHERE EventDateID = #EventDateID#
</cfquery>
</cfloop>
You should validate the values and/or use cfqueryparam
