SSIS and the FOREACH LOOP and no Connection String Property

Hello!
I am tryng to set up a Foreach Loop. I have everything configured properly but the Expression Property does not have Connection String in it as is shown in several examples. Anyone have any suggestions?
Thanks
Mike

Mike,
I think you are confusing Flat file connection manager's conn string property with for each loop (FELC). As Arthur said, FELC doesn't have any conn strings !!!. As per xample, you have to got to properties of the flat file conn manager (highlight FF conn
manager and press F4). Then hit eliipses and there you'll see connecting string property in dropdown. This is explained in the link you are seeing !!!!
Thanks, hsbal

I run Dev 6i on Windows 2008 R2 64-bit,the forms are working fine after connection to the database but the reports continue to request for username, password and database connection string every time i try to open a report.

I receive REP-0501: Unable to connect to specified database. I run developer 6i application on windows 2008 r2. I have applied the nn60.dll and nnb60.dll files to the \BIN directory. The forms are working fine. The reports will only display after the correct user id (username, password and database connection string) is supplied. This is happening to all attempts to open already complied form. Pls, help.

If you are connecting to an Oracle 11g database, remember that by default the passwords are case sensitive. To disable that, run
ALTER SYSTEM SET SEC_CASE_SENSITIVE_LOGON = FALSE;

SSIS 2008 R2 Foreach Loop Container on ADO object in Endless Loop

SSIS 2008 R2
I have an object Variable populated by a SQL Query. I then attach it to a Foreach Loop Container with "Foreach ADO Enumerator" and define the variable mappings. Inside the Foreach Loop is a series of tasks. It appears that the
tasks are processing each of the rows in the Object but it also appears that the Foreach loop never stops but runs until I kill it. I was under the impression that the Foreach loop would stop when after the last row in the Object was consumed.
As it is now, the Foreach Loop is useless as it runs forever.
Any suggestions would be appreciated.
Thanks,
Michael
P.S. I have determined that the ADO object has a size or count limitation which if exceeded causes the Foreach Loop task to malfunction in both Studio and as an Agent job. I could not find a limit in MS docs, but there sure seems to be
a limit somewhere which everyone should be aware of. 5,000 rows exceeds the limit, in my case.

A typical memory limit rather, especially noticeable in dev env where it is 32 bit

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

SSIS Expression to Server Name from a Connection String

Hi,
I have an SSIS variable which contains a connection string as follows; -
User::strDYNconnection {Data Source=myServer;Initial Catalog=myDatabase;Provider=SQLNCLI10.1;Integrated Security=XXXX} String
I need to get the server name from the above variable using an SSIS expression so I can pass the server name to another function.
Thanks in advance,
Kieran.
Kieran Patrick Wood http://www.innovativebusinessintelligence.com http://uk.linkedin.com/in/kieranpatrickwood http://kieranwood.wordpress.com/

Hi Kieran,
This works fine when the Data source comes first in the connection string (which it usualy does). but when it doesn't,
e.g.
Initial Catalog=myDatabase;Data Source=myServer;Provider=SQLNCLI10.1;Integrated Security=XXXX}
you will get 'myDatabase' as an answer
I would add 'Data source =' in the find string (and adjust for length of this search string to add sufficient offset)
e.g.
SUBSTRING(RIGHT(@[User::strDYNconnection],LEN(@[User::strDYNconnection]) - 11 - FINDSTRING(@[User::strDYNconnection],"Data Source=",1)),1,FINDSTRING((RIGHT(@[User::strDYNconnection],LEN(@[User::strDYNconnection]) - 11 - FINDSTRING(@[User::strDYNconnection],"Data
Source=",1))),";",1) - 1)
Even this is not foolproof, when the Data source is the last element in the string and there is no ending ;
e.g.
Initial Catalog=myDatabase;Provider=SQLNCLI10.1;Integrated Security=XXXX;Data Source=myServer}
the formula needs to be extended further with a ( ? : ) operator around the last operator to see if the last ";" was found or not.

Changing the server name on package connection string.

I have a connection string in a package which is a local connection string and not in project connection manager and isn't parameterize as well. Now I need to change a server name of the connection property without using editor. Can I do that and how ?
Moyz Khan

I agree about using configuration for connection string but unfortunately this is an inherited project/packages . And my task it to make these run as currently I don't have luxury to modified it.
So I was able to change most of the connection string with below update
update[SSISDB].[internal].[execution_parameter_values]
setparameter_value=replace(cast(parameter_valueasvarchar),'OldServer',NEwServer)
update[SSISDB].[internal].[object_parameters]
set[design_default_value]=
replace(
cast([design_default_value]asvarchar(1000)),'OldServer','NEwServer')
Now the only one its complaining is the Project connection string . If I know where to look and update that I might be able to run these packages .

The ForEach Loop Enumerator is Empty - SSIS Error when executing through CMD via VBA

I am currently working on a SSIS package that is to be triggered through CMD via VBA (Access). All that the package does is read a bunch of files from a folder and upload them into a table in SQL Server. The tricky part comes is that this folder location from
which the package is to read the files is dynamic.
I figured out a way to make it dynamic, by using variables
I have used the following variables:
"Directory" against DIRECTORY in COLLECTION>>EXPRESSIONS in the ForEachfile Enumerator,
"FilePath" (With Index 0) in the Variable Mappings
PROBLEM : As the final link in the chain, I have used following to be triggered from VBA
dtexec \f "C:\Desktop\SSISAppend.dtsx" /Set "\Package.Variables[User::Directory].Property[Value];C:\Desktop\AppendFiles"
When I try to execute the package using the above command, it gives out the error
Code : 0x8001C004
Description: The For Each File Enumerator is empty. The For Each File enumerator did not find any files that meatched the file pattern, or the specified directory was empty.
But, when I run the package from MS VisualStudio 2008, the package runs fine, takes the location of the file assigned to the variable "Directory".
All help is appreciated

Where are you executing the package from? You're giving an aboslute path so this will work only if package as well as the folder is in the same machine from which you execute the above code. Otherwise you need to use UNC path.
Another thing to check is what login is executing the command and you need to ensure it does have access to the directoty path as well as to the path where package resides.

Modifying child node instances in the foreach loop

Dear All,
I have implemented a custom BO with a child node. On executing an action on the root node, i want to loop through the associated child nodes and create an SAP standard BO instance for every child node instance.
I then want to associate the ID of the standard BO created to a field in the child node.How do i modify the child node instance in this loop?
Any pointers would be really appreciated.
Thanks a lot for your help.
- Kavya

Hello Kavya,
First you want to lopo over all child nodes
     ( var myChild in this.Child ) {
Then you create the standard BO
     customer = Customer.Create();
Now assign the InternalID to your Child ID
     myChild.ChildId = customer.InternalID;

FOREACH LOOP IN SSIS

I have a folder structure as below:
Main
--201310
----October language line.xlsx
----October billing report.xlsx
-- 201311
----November language line.xlsx
----November billing report.xlsx
-- 201312
----December language line.xlsx
----December billing report.xlsx
so the folder structure is main -> yearmonth folder -> files.
I have to loop through the yearmonth folders and then pick all the files from respective yearmonth folder.
Could someone help me do this. I am a newbie to SSIS.

Use the Foreach Loop File Enumerator. More details
here.
It fills an SSIS String variable with the complete path of the excel file. You can use that variable in an expression on the
ExcelFilePath property of the excel connection manager.

Is it possible to load multiple .xlsx files into a SQL Server Table using SSIS and a Foreach Loop Container when each Excel spreadsheet is comprised of two different worksheets

So we have an Invoice .xlsx File from a 3rd party vendor. It contains two worksheets..."Enrolled" and "Engaged". The data and data columns in each worksheet is different. Is it possible to loop through multiple .xlsx files using SSIS
and a Foreach Loop Container for each spreadsheet, and then another Foreach Loop Container to control each worksheet, and pump the Excel data into a SQL Server Table first for "Enrolled" and then for "Engaged"? How can I control the Foreach
Loop Container in SSIS to process ONLY the "Enrolled" worksheet first? And then the "Engaged" worksheet next?
I know I have multiples out here and I apologize for that...but right now it seems as though I take three steps forward and then two back.
Any help would be GREATLY appreciated!
Thanks in advance!

If the structure of the Excel sheets does not change from file to file then you can by having one ForEach Loop processing always the "Enrolled" sheet and another always the "Engaged" this is doable because the Excel OLEDB connector allows
to pick individual sheets, it is problematic therefore when sheet names themselves change.
MSDN has an example: https://msdn.microsoft.com/en-ca/library/ms345182.aspx

[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:

How do I access a value of a variable in SSIS and control the flow accordingly based on its value?

So I have a Foreach Loop Container that Enumerates a read Excel spreadsheet and this Foreach Loop get its User::SheetName. Can I change my flow accordingly based on the value of the User Variable User:SheetName that is dynamically valued by the Foreach Loop
Container? So if the User::SheetName is "Enrolled", I want to load that worksheet to a certain SQL Server Table using an Excel Source and OLE DB Destination and if the User::SheetName is "Engaged", I want to load its worksheet contents
to a different SQL Server Staging Table. What Task can I use to determine the value of User::SheetName or am I going to have to write a C# script to do this?
Any help and/or suggestions are GREATLY appreciated.
Thanks!

Hi ITBobbyP,
According to your description, you want to read data from excel by using the Foreach Loop container with the appropriate enumerator. If that is the case, please refer to the following steps:
Inside the ADO NET enumerator, add a data flow task.
Inside the data flow task, add an Excel source.
Open the Excel source, and point to the Excel data source set up in the file enumerator.
Select one of the sheets that shows in the drop down.
Close the Excel source.
Select the Excel source.
In the properties window, copy the name of the sheet you selected. It's in the 'OpenRowset' property.
Set this as the initial string in your sheet name variable created to gather the sheet name from the ADO NET enumerator.
Select the Excel source.
In the properties window, change the 'AccessMode' to OpenRowset from Variable. This will change the property 'OpenRowset' to 'OpenRowsetVariable'.
Change the 'OpenRowsetVariable' to the variable created to hold the sheet name via the dropdown.
Open the Excel source. You should see your variable as the sheet name.
Click the 'Columns' tab to verify you can connect and mess with columns.
For detail information, please refer to the following document:

How to bypass errors in the control flow in a foreach loop in SSIS?

Hi All,
Can anyone please get me through the solution for the below scenario:
- I have multiple XML files existing in the source system from where I need to read the data from each XML, validate and pull to staging database.
- So, to read the XML files from source, I have a foreach loop which will get the XML files from the source folder one by one and executes.
- There are multiple data flow tasks, script tasks, SQL tasks etc in the foreach loop to validate the business requirements.
Question: If there is an error in any of the component in foreach loop, it should log the error, come out of the loop from that point and pick up the next file with out stopping the execution. How can I achieve this?
Thanks,
Sri

Hi Sri,
According to your description, when there is an error in any of the component in Foreach Loop Container, you want to continue processing rest of the loop after recording the error file details.
To achieve your requirement, the first thing you need to do is create an OnError event handler for the Data Flow (or any other child executable). Once the event handler is created show the system variables in the variables window, locate the Propagate variable
and set it to false.
For more details, please refer to the following two blogs:
