The property XMLDataVariable on the XML Source was empty - Case Foreach Loop Container

I have very simple XML source and OLE DB Source in Foreach Loop Container,
but seem to get error, because XML Source cannot find the XML.
"Error at Data Flow Task. The property XMLDataVariable on the XML Source was empty"
Variables:
FileExtention = *.xml
FilePath =
FolderPath = C:\Customer\XML
XML Source:
Data Access mode = XML file from variable
Variable name = User::filePath
Foreach Loop Container:
Enumerator = Foreach File Enumerator
Expression-Directory = @User:FolderPath
Expression-FileSpec = @User::FileExtension
Enumerator Folder = C:\Customer\XML
Files = *.xml
Variable mapping-User::FilePath = 0

Have you filled the variable (filePath) with a default value? Otherwise the XML Source cannot validate. Alternative is look for a property "DelayValidation". In most cases this is a property of the connection manager, but you're not using
one for the xml source....

Bug on the property "disabledDays" of the component af|inputDate ?

Hi,
I think there is a bug on the property "disabledDays" of the component af|inputDate :
<af:inputDate disabledDays="#{MyInputDate.disabledDays}"
public class MyInputDate {
    public DateListProvider getDisabledDays() {
        return new DateListProvider() {
            public List<java.util.Date> getDateList(FacesContext pFacesContext, Calendar pCalendar, java.util.Date pDate, java.util.Date pDate1) {
                List<java.util.Date> my_array = new ArrayList<java.util.Date>();
                try {
                    my_array.add(new SimpleDateFormat("MM/dd/yyyy").parse("1/1/2012"));
                } catch (Exception e) {
                return my_array;
Problem:      While Only the 1 January 2012 cannot be selected, December 1, 2011 cannot be selected too !
It's the same for every first day of each month...
So, if it's possible, how can i use this property without this bug ?
I use Oracle JDeveloper 11g Release 1 (11.1.1.4.0).

Hi,
the issue indeed reproduces. The fix however is pretty simple
    public List<Date> getDateList(FacesContext facesContext, Calendar calendar, Date startDate, Date endDate) {
        ArrayList<Date> l = new ArrayList<Date>();
        Date d;
        try {
            d = new SimpleDateFormat("MM/dd/yyyy").parse("01/01/2012");
            if (endDate.compareTo(d)< 0){
                //ignore setting
            else{
                l.add(d);
        } catch (ParseException e) {
                e.printStackTrace();
        return l;
    }Just check if the date you set is earlier than the min range of the actual date display. If it is, don't set it as it is of no use anyway

[Forum FAQ] How to calculate the total count of insert rows within a Foreach Loop Container in SSIS?

Introduction
We need to loop through all the flat files that have the same structure in a folder and import all the data to a single SQL Server table. How can we obtain the total count of the rows inserted to the destination SQL Server table?
Solution
We can use Execute SQL Task or Script Task to aggregate the row count increment for each iteration of the Foreach Loop Container. The following steps are the preparations before we add the Execute SQL Task or Script Task:
Create a String type variable FilePath, two Int32 type variables InsertRowCnt and TotalRowCnt.
Drag a Foreach Loop Container to the Control Flow design surface, set the Enumerator to “Foreach File Enumerator”, specify the source folder and the files extension, and set the “Retrieve file name” option to “Fully qualified”.
On the “Variable Mappings” tab of the container, map the variable FilePath to the collection value.
Drag a Data Flow Task to the container, in the Data Flow Task, add a Flat File Source, a Row Count Transformation, and an OLE DB Destination, and join them. Create a Flat File Connection Manager to connect to one of the flat files, and then configure the
Flat File Source as well as the OLE DB Destination adapter. Set the variable for the Row Count Transformation to “User::InsertRowCnt”.
Open the Property Expressions Editor for the Flat File Connection Manager, and set the expression of “ConnectionString” property to
“@[User::FilePath]”.
(I) Execute SQL Task Method:
In the Control Flow, drag an Execute SQL Task under the Data Flow Task and join them.
Create one or using any one existing OLE DB Connection Manager for the Execute SQL Task, set the “ResultSet” option to “Single row”, and then set the “SQLStatement” property to:
DECLARE @InsertRowCnt INT,
               @TotalRowCnt INT
SET @InsertRowCnt=?
SET @TotalRowCnt=?
SET @TotalRowCnt=@InsertRowCnt+@TotalRowCnt
SELECT TotalRowCnt=@TotalRowCnt
On to parameter 1.
On the “Result Set” tab of the Execute SQL Task, map result 0 to variable “User::TotalRowCnt”.
(II) Script Task Method:
In the Control Flow, drag a Script Task under the Data Flow Task and join them.
In the Script Task, select variable InsertRowCnt for “ReadOnlyVariables” option, and select variable TotalRowCnt for “ReadWriteVariables”.
Edit the Main method as follows (C#):
public void Main()
// TODO: Add your code here
int InsertRowCnt = Convert.ToInt32(Dts.Variables["User::InsertRowCnt"].Value.ToString()
int TotalRowCnt = Convert.ToInt32(Dts.Variables["User::TotalRowCnt"].Value.ToString());
TotalRowCnt = TotalRowCnt + InsertRowCnt;
Dts.Variables["User::InsertRowCnt"].Value = TotalRowCnt;
Dts.TaskResult = (int)ScriptResults.Success;
          Or (VB)
          Public Sub Main()
        ' Add your code here
        Dim InsertRowCnt As Integer =
        Convert.ToInt32(Dts.Variables("User::InsertRowCnt").Value.ToString())
        Dim TotalRowCnt As Integer =
        Convert.ToInt32(Dts.Variables("User::TotalRowCnt").Value.ToString())
        TotalRowCnt = TotalRowCnt + InsertRowCnt
        Dts.Variables("User::TotalRowCnt").Value = TotalRowCnt
        Dts.TaskResult = ScriptResults.Success
       End Sub

Hi ITBobbyP,
If I understand correctly, you want to load data from multiple sheets in an .xlsx file into a SQL Server table.
If in this scenario, please refer to the following tips:
The Foreach Loop container should be configured as shown below:
Enumerator: Foreach ADO.NET Schema Rowset Enumerator
Connection String: The OLE DB Connection String for the excel file.
Schema: Tables.
In the Variable Mapping, map the variable to Sheet_Name, and change the Index from 0 to 2.
The connection string for Excel Connection Manager is the original one, we needn’t make any change.
Change Table Name or View name to the variable Sheet_Name.
If you want to load data from multiple sheets in multiple .xlsx files into a SQL Server table, please refer to following thread:

Can I append the file name from a Foreach Loop Container Enumerator into a SQL Server Statement?

I would like to pass back via an Email the name of the file that was successfully FTP'ed to a remote server. And I was hoping to do this via an Execute SQL Task with the following SQL Statement...but I just don't know if it will append the Foreach Loop Container
variable enumerator to the appended Email message that I am building in SQL Server or if I can and how I can...
I sort of get the feeling that I can try and do this via Dynamic SQL...I just don't know if by building dynamic SQL if my Foreach Loop Container enumerator variable will be appended to my Email Message via the SQL Server UPDATE
@[User::FTPFHFileName]
Or do I add a Data Flow Task and an OLE DB Command and pass the Foreach Loop Container enumerator variable to a Stored Procedure referenced in the OLE DB Command via a "?"
Thanks for your review and am hopeful for a reply.

SSIS Variable Expression not Picking Up the value dynamically set from a Foreach Loop container

Hello, everyone,
I have three variables in my SSIS package:
1) ReportLoc that holds a file path (c:\test, not changed)
2) ReportFileName that holds a file name that get assigned in a Foreach Loop container (file1, file2, etc.)
3) OutputFilePath that is the full file pathname, set in the expression: @[User::LocalPath] + "\\" + @[User::ReportFileName]
All three variable have the package scope.
I expect OutputFilePath will be asigned values like c:\test\file1, c:\test\file2, etc.
However, it alwasy remains an empty string.
Anything I did wrong? Any help and information is greatly appreciated.
Regards

That's it -- I forgot to set Evaluate as Expression to true.
Thank you very much for your reply and solution! Really appreciate it!

UnPivot in the foreach loop container

Hi
I would like to "unpivot" SEQUENTIALLY each row in a table
Before the pivot task in the foreach loop container how to read sequentially each row ?
1/ from a PK ?
2/ from parameters with a WHERE field1 = ? and field2 = ? and field3=?....
These parameters have been set up prevoiouly in the loop
3/ Others ? ...
Thx for your help

Hi Gilles,
To achieve your goal, you can simply use the Unpivot Transformation or UNPIVOT statement in T-SQL.
If you want to use Unpivot Transform, it should be configured as follows:
If you want to use T-SQL, the query is like below:
SELECT u.Name, u.Category
FROM [dbo].[MyTable]
UNPIVOT
(Name for Category in (Field1, Field2, Field3)) u

Excel Source cannot find sheet when using Foreach Loop Container

I have SQL Server 2012 SSIS. I need help with Foreach Loop container.
1) I have C:\\Excel\ folder and multiple Excel.xlsx files are stored there to be imported
2) I have Foreach Loop Container
-Foreach File Enumerator is selected
-Expressions are empty
-Folder is set as C:\\Excel\
-Files is *.*
-Variable is created. User::Filename, 0
2) I have created variable FileName, String,0
3) I have Excel Connection Manager
-ExcelFilePath = @[User::FileName]
4) I have data flow task with Excel Source and OLE DB Destination
Error occured with Execute:
[Excel Source [2]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E37.
[Excel Source [2]] Error: Opening a rowset for "SheetName$" failed. Check that the object exists in the database.
Kenny_I

Hi Kenny_I,
The issue occurs because you have not specified a valid value for the variable @FileName. The error persists even if we set the “DelayValidation” property of the Excel Connection Manager to True. After you assign a value like “C:\Excel\Test1.xlsx” (without
quotes) to the variable, the package should work fine.

Using an ssis variable object as a data source in a foreach loop container

hi we run 2012 std. I have an ssis var of type object that is hydrated from a dynamic query in an execute sql task. I can count on one thing in this object and that is that ID will always be the first "col" on each "row".
Otherwise, resultset can contain a variety of things based on params passed to this sub pkg.
I'd like to introduce a for each loop on this object and tap into index 0, ie the id column.
The first question is "will I be able to parse this object's id in a for each component?".
In the for each loop container properties, I c an item enumerator, ado enumerator, ado.net schema rowset and variable enumerator as enumerator choices. Which do I want if the answer to the 1st question is yes?

hoping 2 avoid a data flow. I wonder if what u r saying is that I cannot use an felc to do this. Or if u r showing one of many alternatives.
Sorry, bad title. I just changed that.
I just tried foreach from variable enumerator and aborted with a message that said my variable "coll" doesn't have an enumerator. Going 2 try some of the other choices.
I just tried ado enumerator and from what I can c it isn't actually iterating thru my resultset even once.
I just tried a foreach item enumerator giving "column 0" a data type that matches my ID but from what I can tell the component isn't iterating thru my collection.
ado.net schema rowset doesn't look inviting at all in that it looks like it wants to go back to the db. Not what I had in mind having already gotten this resultset into memory.
according to this article u r supposed to be able to do this using ado enumerator

Need a query based on the property value of the other itemDescriptor

Hi,
I have following structed repository(both items in repository) with itemDesc1 and itemDesc2. Now i have the value of prop2 (of itemDesc2 ) . Using this i want to write query (using QueryBuilder) to get the value for one of the property of itemDesc1.
<item-descriptor name="itemDesc1" >
      <table name="xx" type="auxiliary" id-column-name="id" >
         <property name="prop" column-name=xx" item-type="itemDesc2" />
     </table>
</item-descriptor>
<item-descriptor name="itemDesc2"   >
             <table name=yy" type="primary" id-column-name="id">
         <property name="prop1" column-name="xx" item-type="itemDesc2" />
          <property name="prop2" column-name="xx" item-type="itemDesc2" />
           <property name="prop3" column-name="xx" item-type="itemDesc2" />
     </table>
</item-descriptor>
Thanks in advance

Jack,
Simplest solution is probably a lookup table containing a list of positions and the salary level associated with each position:
The formula that retrieves the salaries from the rate table is shown above the Main table (left). Rate Table, to the right, contains the list of positions and the salary associated with each position.

Add a dummy execute sql task as first step inside loop and add a breakpoint to that for OnPreExecute event and check value of variable during each iteration to see if it gets value of each child package witin folder correctly.

The reason is in the first line of the error. It doesn't have anything to do with the size of your XML file - it has to do with the contents of the "MsgLev1" column. You (or the XSD) has indicated that the values in this column not exceed a certain size - but one of the values in the file that's failing is larger than that.
In order to fix the problem, you're going to need to increase the allocated space for that column. In order to do that, you're going to need to find out what the required size of that data is - either from someone who ought to know, or by direct examination of the file. If you want to know which entity has this overly large data element in it, you need to configure the error handling of the XML Source to "redirect truncation errors". Then you can hook up the XML Source's error output to another destination where you can see which rows are problematic.

Help comparing the value of a button using the Property Node (I get a variant)

Dear Sirs:
(I'm using LabView 6. I guess the solution is different for 6.1)
Currently I have created an array of Boolean RefNums (which point to many, many buttons). When I need to know when any (and which) of the buttons was pressed I just compare every element on the array with the constant TRUE. It fact, as the array is built from RefNums, I should compare the VALUE from the Property Node.
The problem here is that the Property Node for this type of Boolean is a LV Variant, and I need to compare this with a TRUE/FALSE value.
I tried to convert the TRUE constant to a LV variant and visc. But nothing works... I always get that none of the buttons was pressed.
Here it co
mes the question: "How can I compare the value of a Property Node for a Boolean (Button) with a TRUE (or False) constant?"
BTW, maybe I should explain why I'm using RefNums instead of the direct values: As my project requires tons of buttons, I would preffer using RefNums to refer to them. (I.E. I could use a single VI that takes the RefNum and formats the button to hide it for certain users).
I have enclosed a VI that contains what I've achieved until now, which is nothing
I appreciate your time and help.
Best regards,

Javier,
There is another problem in your code: the booleans are not polled by the main loop so they will remain false until the user presses them again. This renders the boolean latch action useless.
What you can do is to change the mechanical action of the booleans to non-latch. When you detect a "true" in the polling loop, set the boolean to false again. One added benefit is that once all boolean are non-latch, the value property won't be a variant but a boolean so conversion is no longer needed.

Not able to change values in the Property Inspector

Hello!
Can some one please help me with this. I was working in
Director when I noticed that all of a sudden I wasn't able to
change the values in the property inspector, specifially the sprite
properties such as the x and y coordinates and the width and
height. I'll type in a value and then I will get an error sound and
it will revert to the previous value. How can I fix this??
Thanks!

Hi Ringerz,
I've seen the PI lock up sometimes. What usually works is to
switch to List Viw
Mode. Never have trouble there. Then, close Director and
reopen. Think it's jus a
bug that hasn't been fixed yet.
