Looping Over INSERT

I've got a form. The form asks the visitor their address
(first name, last name, street address, apartment number, city,
state, and zip code... each a separate text field). This form is
repeated 10 times on the page, allowing the visitor to enter
multiple addresses. I've given each form field a unique name by
just appending "_1" or "_2" after it. For example, my fields are
named...
FIRST FORM BLOCK
first_name_1
last_name_1
SECOND FORM BLOCK
first_name_2
last_name_2
Each form block (address) will be inserted into a table in my
database as a new row. Is there a quick and easy way to loop over
the insert 10 times, rather than have 10 separate INSERT statements
in my code? A CFLOOP would work just fine if not for dynamic form
field names, but I would have to take into account the "_X". I want
to say I've done this before; I'm just overthinking.

<cfloop from="1" to="10" index="i">
<cfquery ...>
INSERT INTO ...
(aCol,bCol,cCol...)

#form['first_Name_' & i]#,
#form['last_Name_' & i]#
</cfquery>
</cfloop>
The array notation for a complex variables is a very powerful
concept.
Many advance techniques can be used with it.

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 TreeMap with for|foreach

I am a student programmer and am impressed how the APIs for the different collections are very similar if not completely identical.
I used treemap.keySet() to loop over TreeMap<String, MyVeryOwnClass> successfully with a while loop. But it seems impossible to do the same with the newish for-each loop. Or have I missed the point somewhere?
Regards,
Hedley

Okay, I've got the for/each loop working its way through my Applicant TreeMap as follows:
    public String findApprovedApplcnt()
        String applicantKey = "";
        for (Map.Entry<String, Applicant> entry : applicantList.entrySet())
            Applicant applicant = entry.getValue();
            boolean approved = applicant.isApproved();
            if (approved);
                applicantKey = applicant.getApplcntKey();
                // The String key is hashed and stored in an instance variable when object created.
                // It is subsequently retrieved and used when the object is added to the tree map.
                break;
        return applicantKey;
    } // findApprovedApplcnt(..)In the Applicant class is the flag 'private boolean approved = false;' (initially), accessed by the method .isApproved(). What the loop is supposed to do is examine each Applicant object applicant in turn, skip over those where approved = false, and grab the key of the first applicant where approved = true, then break out of the loop and return the key.
Trouble is, it is grabbing the key of the first applicant it encounters regardless of whether approved is either true or false! I have gone nuts over this, stepping through in the debugger, inserting println statements to check the value of approved when it is retrieved, attempting to desk check, etc.
So what is the obvious error to which I am completely blind?

How can i loop over treeview selected nodes and then to delete each node if it's a directory or a file ?

I have this code:
if (s == "file")
file = false;
for (int i = 0; i < treeViewMS1.SelectedNodes.Count; i++)
DeleteFile(treeViewMS1.SelectedNode.FullPath, file);
I know it's a file and it is working if it's a single file.
On the treeView i click on a file right click in the menu i select delete and it's doing the line:
DeleteFile(treeViewMS1.SelectedNode.FullPath, file);
And it's working no problems.
But i want to do that if i selected some files togeather multiple selection then to delete each file.
So i added the FOR loop but then how do i delete from the SelectedNodes each node ?
The treeView SelectedNodes dosen't have FullPath like SelectedNode also doing SelectedNodes[i] dosen't have the FullPath property.
Same as for if i want to delete a single directory or multiple selected directories:
This is the continue of the code if it"s not a "file" (else) it's null i know it's a directory and doing:
else
file = true;
RemoveDirectoriesRecursive(treeViewMS1.SelectedNode, treeViewMS1.SelectedNode.FullPath);
Also here i'm using SelectedNode but if i marked multiple directories then i how do i loop over the SelectedNodes and send each SelectedNode to the RemoveDirectoriesRecrusive method ?
My problem is how to loop over SelectedNode(multiple selection of files/directories) and send each selected file/directory to it's method like i'm doing now ?

foreach (TreeNode n in treeViewMS1.SelectedNodes)
// Remove everything associated with TreeNode n here
I don't think it's any harder than that, is it?
If you can multi-select both an item and one of its descendents in the tree, then you'll have the situation that you may have deleted the parent folder and all of its children by the time you get around to deleting the descendent. But that's not such
a big deal. A file can get deleted externally to your program too - so you'll just have to deal with it having been deleted already (or externally) when you get around to deleting it yourself.

[Solved] Foreach loop that loops over all files in a folder does not consider first file found

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

"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
Christopher

Hi,
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

Message-Mapping: nested Loops over Elements

Hi Experts,
I have problems with my Message-Mapping in the IR. I have a source and a target structure. In the following I will give you easy examples of these structures:
<u>source structure:</u>
   <E1EDP01>
      <E1EDP19>
         <QUALF> ... </QUALF>
         <IDTNR> ... </IDTNR>
      </E1EDP19>
      <E1EDP19>
         <QUALF> ... </QUALF>
         <IDTNR> ... </IDTNR>
      </E1EDP19>
   </E1EDP01>
   <E1EDP01>
      <E1EDP19>
         <QUALF> ... </QUALF>
         <IDTNR> ... </IDTNR>
      </E1EDP19>
      <E1EDP19>
         <QUALF> ... </QUALF>
         <IDTNR> ... </IDTNR>
      </E1EDP19>
   </E1EDP01>
<u>target structure:</u>
<LineItem>
   <IDTNR></IDTNR>
</LineItem>
<LineItem>
   <IDTNR></IDTNR>
</LineItem>
That means:
For every <E1EDP01> in the source structure I create one <LineItem> in the target structure. One E1EDP01-Element can contain more than one E1EDP19-Elements. I have to loop over these E1EDP19-Elements, because I have to locate the Element <QUALF> with a given (fixed) value. The Mapping should put the value from the Element <IDTNR> from the source structure - where the QUALF-Element has this given value - in the IDTNR-Element of the target structure.
I tried it with a UDF, but only the first <IDTNR> in the target structure got filled.
Thanks for your help
Christopher

Thank you,
but how I can set the Elements IDTNR and QUALF to the context E1EDP01?
In the splitByValue-Function do I need "each value"?
best regards
Christopher

Looping over cfset tag

Hey Guys,
I am having a problem with cfloop. What I am trying to do is
calculate points on an Oline March Madness Pool. I need to evaluate
if the user picks are equal to the game winners. I can do it if I
manually type each pick # and each game # but I would much rather
loop over a cfset tag since there are 63 picks and games. You can
check out my code below to get a better idea of what I am trying to
do. While I know I can't include the #'s on the right side of the
cfset tag in this way I included them anyways to better illustrate
where I would like to loop it. Is there a way to do this, or will I
have to manually set each pick?

<cfif getGames.game#l# EQ
userPoints[#userID#]["pick#l#"]>
I'm going to guess this is line 27 or very near it.
Your actual <cfset> line looks fine to me assuming all
the relevant keys
exist when they need to exist. I would have written it
something like:
<cfset userPoints[userID]["pick" & i] =
variables["pick" & i]>
The if statement should probably look like this:
<cfif getGames["game" & i] EQ
userPoints[userID]["pick" & i]>
All your index variables are the letter "i" and not the
number "1"
aren't they? I don't believe a singe number is a valid CF
variable name.

Looping over fields from internal table

In a FM I have to check records of two ITABs against each other. Most fields can be checked 1:1 but some must be checked according to some business logic.
I first want to check field-by-field and then I want to deal with exceptions.
Question: How can I loop over fields in an ITAB in such a manner that I can compare fields?

Hi, you can loop thru the columns(fields) of an internal table like so.
field-symbols: <fs>.
loop at itab.
do.
* Here you can use the field name instead of SY-INDEX
   assign component sy-index of structure itab to <fs>.
   if sy-subrc <>.
   exit.
   endif.
* Now that you have access to the field via field symbol, you can compare
* this value.
Write:/ <fs>.
enddo.
endloop.

Splitting a list (loop and insert)

I have a text file with about 65000 records to be looped and
inserted into a
database. I am using cfhttp to read the list and turn it into
a query. I am
then using that query to loop and insert the records into a
database.
However, its too large and the server is timing out. Is there
a break the
list into 2 pieces and do it in serial?
I am using:
<cffunction name="getResidential" access="private"
returntype="void"
output="false" hint="">
<cfargument name="ResFile" type="string"
required="yes">
<cfhttp timeout="6600"
url="

firstrowasheaders="yes" />
<cfloop query="Property">
<cfquery name="loopProperty" datasource="bpopros">
INSERT STATEMENT HERE
</cfquery>
</cfloop>
</cffunction>
Is it possible to do something like:
Function 1
<cfloop from="1" to="40000" index="i">
</cfloop>
Function 2
<cfloop from="40001" to="#Query.RecordCount#"
index="i">

I like your second solution, but wouldn't I need access to
the actual web
server? I need to do this on hosting. I am downloading the
files from a Real
Comp and then looping the data into my client's database for
searching. I
wanted to just use the files as a flat database and just
query or query off
of it, but there is a new file everyday. Only one update
(Sunday) is the
master list of 45-60k records. All the rest (Mon-Sat) are
just small
updates.

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>
WHERE ROWNUM <= 1;Regards,

Looping over QoQ Where Clause

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?
Clay
P.S. Here is a code sampling...
    <cfquery name="rsGroup" datasource="nps">
    SELECT *
    FROM "GROUP"
    WHERE GROUP.PrimaryGroup = '#form.primarygroup#'
    </cfquery>
    rsGroup - <cfdump var="#rsGroup#">
    <cfloop query="rsGroup" startrow="1" endrow="#rsGroup.RecordCount#">
        <cfquery name="rsGroupQoQ" dbtype="query">
        SELECT *
        FROM rsNPS
        WHERE rsNPS.grp = '#rsGroup.group#'
        </cfquery>
    </cfloop>
    rsGroupQoQ - <cfdump var="#rsGroupQoQ#"><cfabort>

ok...I figured it out. I thought I would post my solution in case anyone else runs into this. Also, if anyone out there has a better way, let me know.

<cfset GroupArray = ArrayNew(1)>

<cfset addMainGroup = QueryAddColumn(rsNPS,'mainGroup',GroupArray)>

<cfloop query="rsNPS" startrow="1" endrow="#rsNPS.RecordCount#">
    <cfif rsNPS.GRP EQ "xxxxx"><cfset rsNPS.mainGroup = "yyyyy"></cfif>
    <cfif rsNPS.GRP EQ "xxxxxxxxxx"><cfset rsNPS.mainGroup = "yyyyyyyyyy"></cfif>
    <cfif ...etc. ...
</cfloop>

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.
Pradeep

Hi,
You can try this when it comes to converting things
    WHILE myData IS NOT INITIAL.
do something
    ENDIF.
    myData = myData+1(*).

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!).

A slightly simpler version using the structure form of the
<cfloop...>
tag. It also demonstrates both array notation, that you used,
as well
as dot notation. Finally it puts a single <cfoutput...>
block around
the entire loop. This can provide a small but accumulative
performance
improvement.
<cfoutput>
<cfloop collection="#student#" item="aStudent">
<tr>
<td>#aStudent["firstName"]# OR
#aStudent.firstName#</td>
<td>#aStudent["lastName"]# OR
#aStudent.lastName#</td>
<td>#aStudent["phone"]# OR #aStudent.phone#</td>
</tr>
</cfloop>
</cfoutput>
