Appending Xpath Value to a variable in For Each loop

So I am iterating thru an XML File collection inside a ForEach container. I have an XML Task within this loop of type Xpath.
The Xpath expression on each file evaluates to a value which I want to append as I keep iterating.
How do I go about doing this?? I tried something like User::CheckSum =+ User::CheckSum but it gives and error and I am not sure on which property should it be applied to.
Please understand that it is not one file with multiple nodes but multiple XML files in my scenario.
Any help is much appreciated

I do not think the variable's value gets preserved between hops, anyways, it does not look like a valid approach.
Use the XMLFile Source in the ForEach Loop and capture the needed value into a package variable that you can keep appending to say in a Script Task.

SSIS Help For each Loop Container

I need a little help with this process that I am developing. I am fairly new to SSIS so please bear with me. I have done research online so If I seem limited in my knowledge please apologize me.
Requirement: I have a folder where we will have flat files monthly they could be one or more...
each file will have the following name standard "123456.EEAKQ2.EASDREWA12A.BID".
What I need to do is maintain a table which will have filename and date when it was added to the folder.
I have created a package with the following components "For each loop" which grabs files from a source folder.
This is where I am stuck. I need to grab the file name from the path and insert it into the table.
Can someone help me with this?
Thank you

See similar requirement implemented here
What you need is to declare and use a variable inside for each loop to get filename each time. Then you may use script task to check for pattern within the file for identifying correct files

Unable to set a new value in an extended property from within a For Each Loop

Setting a new value in an extented property fails when the property is dereferenced within a For Each loop usin the item iterator. However, if you use the First or Last Iterators from the Find Targets activity works fine.
The error message is : "Setting a value for this object type is not allowed"
I believe this is a defect, can you please confirm

Looks like a bug that needs to be reported.
While we are figuring out the issue you can work around the bug.
Add another "Find Targets" inside the loop, and use the ID of the current item in the loop to find the target (again) by ID.
And then use Set Variable on the target that was just found...
I know... Not an ideal workaround, so please open a Severity 4 bug for this.

Can we assign value to a variable in PL/SQL Loop

Hi
Can we assign value to a variable in PL/SQL Loops?
DECLARE
V_Num NUMBER;
BEGIN
LOOP
V_Num := 10;
DBMS_OUTPUT.put_line(V_num);
V_Num := V_Num - 1;
EXIT WHEN V_Num = 0;
END LOOP;
END;
In the above program, Can we assign V_num with a value 10????????

In the above program, Can we assign V_num with a value 10????????Yes; the example you posted does that.
When the loop starts, the value 10 is assigned to v_num. You should see that value displayed by the put_line statement.
After that, v_num is set to 10 - 1 = 9.
Next, the EXIT condition is evaluated. At this point, v_num is 9, not 0, so the loop runs again. V_num is set to 10 again, and the loop continues forever (or, in some versions, until the dbms_output buffer is filled and an error occurs.)

How do I make a drop down list of text in numbers as it is made in the example spreadsheet for comparing cars for buying where you can choose a value from a dropdown list for each car?

how do I make a drop down list of text in numbers as it is made in the example spreadsheet for comparing cars for buying where you can choose a value from a dropdown list for each car?

Where is this example spreadsheet? Without seeing it I can only guess at what you are asking.
To make a drop-down list (a pop-up menu in Numbers-speak), format the cell as a pop-up then edit and add to the list of items.
If the example spreadsheet is pulling in a dollar value based on what car you chose in the pop-up, it is probably using LOOKUP or one of the other lookup functions, getting the information from another table (a lookup table). If, instead, these dollar values are what you are choosing in the pop-up, then you need to create a pop-up with these values in it.
The Help menu includes a link to a page where you can download the Numbers Users Manual. It also has a link to the Formulas and Functions guide. Both are useful to new users.

Hi,
Let me make sure u r working with table control.
First u have to create a event(VALIDATE) to do the validation.
Inside the event,
1. First get the current index where user has pointed the curson
2. Once u get the index read the internal table with index value.
3. Now u can compare the col1 and col2 values and populate the error message.
1. DATA : lo_elt TYPE REF TO if_wd_context_element,
l_index type i.
lo_elt = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
CALL METHOD LO_ELT->GET_INDEX( RECEIVING MY_INDEX = l_index.
above code should be written inside the event.
Thanks,

Excel Sheet Looping: For each loop from variable Enumerator

Hi,
Is it possible to do excel sheets looping using For each loop Enumerator as "For Each loop from Variable enumerator" ? If yes, please help.
Also,
I have an excel file with 10 sheets, but want to loop only 5 sheets. Please help..how can i achieve this.
Actually i tried with
1> stored the 5 sheets name into a variable (say 'SheetsName') of type string using script task
2> For each loop container
enumerator - 'For each ADO Schema Rowset enumerator'
connection: ADO
schema: 'Tables'
variable mapping: 'User::SheetsName'
3> Within For each loop container added a data flow task
4> Inside DFT - excel source -
Data access Mode: 'Table Name or view name variable'
Variable Name: 'SheetsName'
but this loops through all the 10 sheets irrespective of only 5 sheets names stored in the variable "SheetsName".
Please help...

I don't think so. To loop through all worksheets of Excel For ADO.NET Schema Rowset Enumerator is the only option.
Please refer:
https://msdn.microsoft.com/en-us/library/ms345182(v=sql.110).aspx
>> I have an excel file with 10 sheets, but want to loop only 5 sheets
So you have configured For Each loop container which loops throgh all sheets and returns you sheet name to variable "SheetName".
Drag and drop one Sequence Container inside ForEach Loop Container and connect it to Data Flow Task.
Right click on connector and use expression: (which will check if current sheet is one of 5 required sheets)
@User::SheetName == "FirstSheet" || @User::SheetName == "SecondSheet" || .....

For Each Loop Issue In SSIS

Hi All,
I have a SSIS Package which unzips the folder and then imports the files and then moves *.zip folders into processed location. If this task is executed as a part of total package its not moving the *.zip folders into processed location, but when we execute
for each loop alone this *.zip folders are moved into processed location. I am unable to figure out the issue here.

Can you put a OnPreExec breakpoint on the file system task (Right click on the file system task > Edit Breakpoint... > Select the first (OnPreExec breakpoint) and when the pkg pauses @ the breakpoint, chk the value of the ZippedFle and FilePathDestination
variable values in your Local window (should be available at the bottom of the SSIS window as one of the tabs and you will need to expand the variable tree and find these two variables and their values). Are you seeing the appropriate values here?

Count the no of irritation in for each loop

I want to count no of irritation in the for each loop container.
Thank you for the help.

If I were using C#, I would do something like that:
First I would define another counter variable
int anotherCounter=0;
then, in for each loop I would parse your text by splitting from the pipe characters. If it matches the value I want, i simply increment the counter.
string[] strColumnArr = strLine.Split("|".ToCharArray());
if (strColumnArr.Length > 0)
if (strColumnArr[1] == "myValue") anotherCounter++;

For each loop container executing multiple times....

Hi,
We are using SQL SERVER version 2005.
I am having a For each loop container and inside that container there are multiple Sequence containers and inside each sequence containers there are Execute SQL Tasks (which are just stored procedures).
Now, when i run sequence containers individually they are running perfectly fine.
But when I run the whole For each loop container, it is just running and running multiple times without ending the process.
I really couldnt figure out what would be the issue?
Any ideas????
Thanks....

Hi grk666,
To check whether the values stored in the object type variable are correct, you can disable all the Sequence Containers within the Foreach Loop Container, and add a Script Task with the following code to display the string type variable value (supposing
you use the string type variable StrVar to store the value retrieved from the object variable):
MsgBox(Dts.Variables(“StrVar”).Value.ToString())
It would be helpful if you could post a screenshot to show the package execution at runtime in BIDS.

How to use for each loop in XSLT when my source is a multilayout file and db

How do I use a for each loop in XSLT when my source is multilayout file and db .
My multilayout file is basically contain 2 kind of data one for employee and another for dependent.
Now my requirement is I want to read each line of data whether it is it is employee or dependent do a join with db and write it in my target file.
eg : File content
1 RichaKumari 311289 TCS INDIA
2 KiarnKumar 456782 BRO RichaKumari 311289 INDIA
2 Ravi 456882 BRO RichaKumari 311289 INDIA
eg : db Content
311289 RichaKumari TCS INDIA Bangalore [email protected]
Now in Final File I need something like this :
1 RichaKumari 311289 TCS INDIA
2 KiarnKumar RichaKumari 311289 TCS INDIA
2 Ravi RichaKumari 311289 TCS INDIA
here 1 and 2 are the identifier which will decide which layout to follow .

Hi,
I think you'll need two nested for-each's... Something like...
<xsl:for-each select="$root/row[layout = 1]">
<xsl:variable name="employee" select="."/>
... write employee ...
<xsl:for-each select="$root/row[layout = 2 and dependentid = $employee/id]">
... write dependent ...
</xsl:for-each>
</xsl:for-each>
Cheers,
Vlad

For Each Loop

As we know that For Each loop is more easy to use and iterate. I want to ask, is it possible to run for each loop in reverse order?
Please help.
I will be very much thank ful to you.

Sure. did you notice that it's you who defines the
running condition, the initial value and the
(positive or negative) increment?He's talking about the new for loop.
The for-each loop can't do everything the old one can. Try reading this explanation.

"for each" loop - under the hood question

Question about the for each loop. Is it optomized? I think this is a poor use of memory management -
for (int i = 0; i < stop; i++) {
Object obj = new Object();
doSomething(obj);
}And this is the ideal, using the same object -
Object obj = new Object();
for (int i = 0; i < stop; i++) {
doSomething(obj);
}So underneath the hood, which is the for each loop comparable to? I love the syntax, it's very clean-looking in the code, but at the same time I don't want to hurt performance.

Consider the following, however:
Object o1 = new Object();
for (Foo foo : fooList) {
    Object o2 = new Object();
     foo.doStuff(o1, o2);
} It will be equivalent to this:Object o1 = new Object();
for (Iterator iter = foo.iterator(); iter.hasNext();) {
    Foo foo = (Foo)iter.next();
    Object o2 = new Object();
    foo.doStuf(o1, o2);
} How could it be any different? It has to keep the behvior of the "old fashioned" iteration.

For Each Loop Load Dynamic Excel Files

Hi All,
SSIS 2005
I want to load excel file .xls one at a time files that have different names without having to select the file in the connection manager, every time. So a user can easily place the excel file in the folder and right the sql job and it loads the file data.
The data flow tasks all work when I manually select the excel file, but I am unable to get this to work dynamically.
I have setup a for each loop with multiples data flow tasks and sql tasks to load my data from file.
Variables:
@filename d:\new file\*.xls
For Each Loop:
ForEachFile Enumerator
Folder: d:\new file\
Files: *.xls
Retrieve File Name: Fully Qualified
Variable Mappings:
User::filename (index 0)
Connection Managers:
Excel Connection Manager: Expressions, ConnectionString @[User::filename]
Error Message: Error at new buyer(package name) the connection string format is not valid. it must consist of one or more components of the form X=Y, seperated by semicolons.
Can anyone assist thanks.

You still need the file name variable.
ExcelFilePath is the fully qualified file name of your Excel file. ie. it contains both the path and file name.
e.g. D:\inbox\myExcelFile.xls
All the steps you mentioned are correct, except you need to set the property of ExcelFilePath of the Excel connection to the variable that you map to in the ForEach Loop:
Connection Managers:
Excel Connection Manager: Expressions, ExcelFilePath @[User::filename]
Hope this helps.
~ J.
