Foreach Loop With XML Source Failure

Oct 25, 2006

I can't import from XML files using a foreach loop. I load an XML file with a generated XSD. When I map the file to the table it has no errors. If I now go back and change to a different XML file, I get an error:

"Error 1 Validation error. Data Flow Task: DTS.Pipeline: input column "COLUMNNAME" (129) has lineage ID 2115 that was not previously used in the Data Flow task. Package.dtsx 0 0"

This is for testing purposes. When I run the foreach loop it does not work. Ironically, I do the exact same thing in another foreach loop with a completely different XML and it works fine.

Here is the broken XSD:

<?xml version="1.0"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="ComputerStatus">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="unbounded" name="computer">

</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

Help. Please. What have I done wrong. I imagine there is a flaw in my XML, but I can't pinpoint it.

Here is a sample of the XML file:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<ComputerStatus>

Foreach Loop .. Renaming Files On Success And Failure ?? Where ? How?

Feb 23, 2008

ummm. sorry, I've read and seen the tutorials but somehow and missing this.

I have a foreach container. Inside a dataflow task, with an XML source, a data conversion (cause of urrr UNICODE) and and an ole DB data source.

By design (and for this simple example), I get a volation if I attempt to load loads with out deleting entries from my table. No biggie, I would just like this simple package to rename my file to extension .good or .bad depending on success of each loop.
Where and what do I need for this?

Thank you for any help or information!

Bulk Insert In Foreach Loop Not Setting Source ConnectionString

Feb 22, 2008

Hello all,

I am running into an issue that seems to be collaborated here: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=188886&SiteID=1.

To summarize, I have a Foreach Loop that uses a Foreach File Enumerator. The loop writes the file names to a variable which is used in the Expressions property for a flat file's ConnectionString. The flat file is used as a source destination in a Bulk Insert Task that is inside the Foreach Loop. The flat file's connection string is not picking up the file name, resulting in this error: "The specified connection "test.txt" is either not valid, or points to an invalid object. To continue, specify a valid connection."

It doesn't work for a file connection manager or a flat file connection manager.

It does work if I replace the Bulk Insert Task with a Data Flow (flat file source -> ole db destination). It also works if I set the file's connection string manually in a script task.

It looks to me as though the Bulk Insert isn't calling whatever method in the connection manager that reevaluates the property expression. Am I missing something or is this a bug? I looked at the connect site, but couldn't find this particular scenario.

Thanks for any insight you might provide!
Jessica

How do you sort files from the Foreach loop container?

I love this component, except I can't get it to sort by filename.

Nice to know how to sort by timestamps also.

Apr 22, 2008



Hello

I have a question

How is foreach loop container - foreach ADO enumerator performace in SSIS package compares to use of cursors in stored procedures

Is there any articles comparing them

I understand a lot of factors can affect the performance, however what is expected performance for the foreach ADO enumerator loop for large dataset. What is Microsoft recommendation for that - recommended - not recommended (using large datasets - over million records)

Thank you

Foreach File Enumerator - Is Absent In Foreach Loop Component

Apr 11, 2007

Hi,

I have no "Foreach File Enumerator" oprtion in the Enumerator Property of the Foreach Loop Component.

I have this enumerator in the c:Program FilesMicrosoft SQL Server90DTSForEachEnumerators folder.

Also I check it in the GAC - it does not here. I try to execute gacutil.exe -iF ForEachFileEnumerator.dll, but it is failed with "Failure adding assembly to the cache: The module was expected to contain an assembly manifest." Seems it is not managed enumerator.



Please help me.

Also information on how to regeister unmanaged enumerators are welcome!

Foreach Loop Doesn't Loop

Mar 3, 2006

I have a foreach loop that is supposed to loop through a recordset, however it doesn't loop. It just repeats the same row, row after row.

I would like to look into the recordset variable but I can't because it is a COM object and the ADODB namespace is not available in the script task.

Any solution to this? anyone experienced anything similar

Foreach Loop?

Jul 10, 2006

I need to execute about dozen packages from another package... how do I dynamically pass the dozen package names to the package and execute using foreach loop...?

idea is to store the names of packages in a text file and set the file connection property reading each package names from the text file... in this way I can just configure/edit the text file from time to time, the packages and the units that I want to execute...

Someone please provide me steps to make it work.

Thanks in adv.

For/Foreach Loop

Jun 10, 2007

Hi,



I'm looping through some query data and doing a Script Task check inside the loop on a datetime field.



If the datetime happens before 10 o'clock:

- Store the data row in Table1

If the datetime happens after 10 o'clock:

- Store the data row in Table2



How can I store the datarow inside the loop without inserting it into a database table?

I need to access the data in the next step after the loop. How can I do this?



Thank you very much!

Doing An Insert In A ForEach Loop

Feb 27, 2008


Help with Looping in a SSIS Package
Scenario:
We have a web app that lets our existing clients insert new locations into a table (Clients) in a SQL Server DB. This table has an Identity column as the PK. This table also has another ID field HBID that is the PK for another table (HLocation) in another Database system (Sybase). The HBID field is given a Default value of €˜1€™ during an insert operation in our (SQL Server) table, Clients. The Sybase database uses a Sequence table for inserting a PK into the table. Whenever our clients insert a new record in Clients (SQL Server), I need to generate a new HBID from the Sequence table in (Sybase), update the HBID in the Clients table (SQL Server) and then finally insert the record with the new HBID into table HLocation (Sybase).
I have devised a SSIS package for this as following: Note all variables are scoped at the Package Level.
Execute SQL Task #1 that drives a For Each Loop with the following properties:
General:
Connection Type: OLE DB
Connection: SQL Server DB
SQL SourceType: Direct Input
SQLStatement:
SELECT COID, HBID, Name, DateCreated
FROM Client
WHERE HBID = '1'

ResultSet: = Full Resultset

Result Set:
Result Name = 0
VariableName = USER::rsClient Variable Type = Object

ForEachLoop with the follwing properties:

Collection:
Foreach ADO Enumerator
ADO Object Source Variable = USER::rsClient
Enumeration Mode = Rows in first table
Variable Mappings:
Variable: Index:
COID 0
HBID 1
Name 2
DateCreated 3

Inside of the ForEachLoop I have another Execute SQL Task to generate a new HBID from Sybase set up as following.

Execute SQL Task #2

Connection Type: OLE DB
Connection: Sybase
SQL SourceType: Direct Input
SQLStatement:
UPDATE Autoinc SET INC_LAST = (INC_LAST+1) WHERE INC_KEY ='HBID';
SELECT INC_LAST AS NewHBID FROM Autoinc WHERE INC_KEY ='HBID'

ResultSet = SingleRow

Result Set:
Result Name = NewHBID
VariableName = USER::NewHBID, VariableType = Int32

Also Inside the ForEachLoop is a Script Task that has all of my variables as ReadWrite = COID, HBID, Name, DateCreated and NewHBID. I concatenate the values in a string a pass the string into a Message Box to make sure they are looping correctly and they are.For example the results might look like the following:

12698, 1, John Doe Trucking, 10/1/2007, 14550
13974, 1, Joe Smith Trucking, 10/1/2007, 14551
10542, 1, Dave Jones Trucking, 10/1/2007, 14552
Etc.

The values 14550 -14552 are the new HBID being generated in the loop.

The problem is that when I try to Update the HBID in the Client table (SQL Server) with another Execute SQL Task I keep getting the same NewHBID number.
In this case 14550 would be updated for every record instead of the next number in the loop.

I have set up Execute SQL Task #3 as follows:

General:
Connection Type: OLE DB
Connection: SQL Server DB
SQL SourceType: Direct Input
SQLStatement:
UPDATE Client
SET HBID = ?
WHERE HBID = '1'(SELECT COID, HBID, Name, DateCreated FROM Client)

ResultSet: = Full ResultSet

Result Set:
Result Name = 0
VariableName = USER::rsNewClient, VariableType = Object

Parameter Mapping:
VariableName USER::NewHBID, Direction = INPUT, DataType = Long
ParameterName = 0

I€™ve tried putting Execute SQL Task #3 inside of the ForEachLoop, connecting it to the output of the ForEachLoop. I€™ve tried setting up a dataflow with a Derived Column using the USER::NewHBID as the Expression.

I still get the same results, 14550 added to every row.

Can any one help or shed some light?

Any and all suggestion will be deeply appreciated!

Thanks !!!

Foreach Loop - Value Back To 0

Jun 14, 2007

Hi,



Let's say you have a Data Flow Task that connects to a Foreach Loop, looping through the data.



Somewhere inside the Foreach Loop, you set an int variable MyInt to a value.



My question:

Is it possable when each iteration begins to set MyInt to 0?



Thanks in advance.

Foreach Endless Loop

Feb 28, 2007

I'm having a problem where I'm using a Execute SQL Task to retrieve a dataset and storing that in an object variable. Then on success of that execute sql task I use a foreach loop task to go through the dataset and do 2 tasks inside the foreach loop. When I execute this package I have ~12 records in the dataset however when I get to the foreach loop in the 2nd iteration it keeps repeating it. It acts like it is stuck on the second record (tuple) and never goes on. I'm using an ForEach ADO Enumerator in the foreach. I've even set a breakpoint on each iteration and no task fails in side the foreach loop. I'm completely perplexed why it will iterate to the 2nd record but get stuck there in an endless loop. I've tried this on 2 different computers (with different data values) and the same thing happens. Does anyone have any suggestions?

Foreach Loop Issue

Jan 3, 2007

Here is what I am attempting to get accomplished. I have an SSIS package that contains a Foreach loop container. This container executes a number of SQL tasks in order: SQL Task 1, SQL Task 2, SQL Task 3.

if the SQL task 1 succeeds it should flow on to SQL Task 2 and 3. This works fine when the SQL tasks do not fail...

In the event of any SQL Task failing control should flow to a send mail task to alert about the failure. Next the Foreach loop container should go to the next enumeration in the Foreach loop container and start the next new SQL task 1. So far I have been able to get the control to flow to the send mail task when a SQL Task fails. What does not work is when one SQL Task fails the entire Foreach loop fails and does not move to the next enumeration. It should only fail the package and move on.

Any help would be appreciated....

Feb 11, 2006

All,

I€™m new to SSIS and have a question about foreach loop container.
Basically, I have 4 data flows and each of them has a variable that need be pass on to the next step, each of the variables will call a same stored procedure.
What should I use here? I guess I can use foreach loop container with the stored procedure inside of it, is that right? I tried all day yesterday and cannot make it work.
The foreach loop container did not call the procedure at all. Could someone kindly tell me how to do it?

Foreach Loop Is Killing Me!!!!!!!!!!!!!!!!!!!!!!

May 26, 2006

I would like your help with the Foreach loop container. Boy, am I having issues with using it for looping through an ADO.NET dataset or what!?!? My control flow has a data flow task that is executing a Data Reader task (creating a .NET dataset for me). Now I go back to the control flow and add a Foreach loop container to loop through each record in my dataset. But which type of the Foreach loop container should I be using? I see an option to use Foreach ADO.NET schema enumerator but not sure how to configure it. Also I used the Foreach ADO option, but setting up variables to go through every column is an absolute pain in the you know what!!?!! I have about 200 columns and I want an easier way to refer to those columns in my transformation phase.

Hope you are able to help me out here.

ForEach Loop With Excel

May 3, 2007



Hi,

I'm attempting to use the Foreach loop container to loop through the excel files located on a shared network folder. I've set up the Excel file connection manager to include the user variable generated from the container, but I get the below error messages when applying that variable to the connection string in the data flow. I've tried everything but I can't seem to get SSIS to recognize the path of the Excel files. I've tried copying the files to my PC, I tried running the package on the server, etc. The connection works fine if I set it up to point to any of the excel files in the network directory, but not with the Foreach loop connection name.



Any help or suggestions would be greatly appreciated! I've looked everywhere and tried everything but to no avail...



Thanks,



Kevin

ForEach Loop Container Question

Nov 6, 2006

Hi

Currently the ForEach Loop container is set to loop over the entire collection of records in my table, but I only need to loop thru the records where the status = x. How is that possible? Can I use expressions to set the enumerator to do something like this. Basiclly the collection values are used for further processing, and I would like to avoid looping thru records which have been processed already, which means they already have a status set to y. Please let me know. Thanks.

Foreach Loop Though All Databases On A Server

Oct 8, 2007

Hi

I am trying to write an SSIS package that will look though all the databases on a server (in this case 2k server) and get the list of tables in each database

I have created a Execute SQL Task with select name from master..sysdatabases where name <> 'Tempdb'

This is connected to a Foreach Loop that uses Foreach ADO Enumerator on the first table from the var generated in step 1 (List of databases)

Within the Foreach loop there is a dataflow that has a a sql command

select @@servername SQLInstanceName
,db_name() DatabaseName
, name TableName
--, getdate() RecordDate
from sysobjects where type = 'u'


This should return all the tables in a database however the databases is not changing it just lists all the tables in the master database times the number of databases on the server


Can anyone point me in the correct direction for this one

Thanks

Enumerating Foreach Loop From Rowset

Jan 22, 2007

Please let me know if I am on the right track here.

I have an Execute SQL Task that selects multiple rows from an OLE DB connection, each row containing 3 columns (data types = string, Int32, Int32). In this task ResultSet = "Full result set" and Result Set > Result Name = 0, Variable Name = [User::viewInfo] which is a user variable with Data Type = Object.

I want to use a Foreach Loop Container to enumerate over the result set rows that are contained in the [User::viewInfo] variable described above. For each resultset row I want to breakout the 3 column values and assign them to 3 corresponding variables that can be referenced in a Data Flow in the Foreach Loop.

Current settings for the Foreach Loop Container: Collection > Enumerator = "Foreach ADO Enumerator", Collection > Enumerator Configuration > ADO object source variable = [User::viewInfo], Enumeration mode = "Rows in the first table". On the Variable Mappings page I select the 3 corresponding user variables I want the rowset column values assigned to, with indexes starting at 1 (not 0).

Thanks - Dana Reed
