Pass Filename To Flatfilesource Inside Foreach Loop

Jul 26, 2007



Hi,
I am using a foreach loop to go through the .txt files inside a folder.
Using a variable I can pickup the filenames the loop is going through.
At present there is a sql task inside the foreach loop which takes the filename as a parameter and passes this filename to a stored procedure.
Now I would like to add one extra step before this sql task. Would like to have a dataflow with flatfile source which connects to oledb destination.

The question is:
While in the loop, how is it possible to pass the filename to the flatfile source using the FileName variable which I have created?

Please note, this is a different question to my other post.

Many Thanks

Apr 12, 2007

Hi everyone,

I've got a Foreach loop container which uses a Foreach ADO Enumerator and works fine.

But problem comes when I launch inside the general loop another Sql Task (select) which sometimes has rows and sometimes hasn't. When it have rows everything is fine the workflow follows fine but when it has not.



I obtain this error (obvioulsy)



[Execute SQL Task] Error: An error occurred while assigning a value to variable "GZon": "Single Row result set is specified, but no rows were returned.".



How to deal with that?



Thanks indeed

XML Task Inside Foreach Loop Container Had To Fail!!!

Aug 9, 2007



Hi,

I am using an XML task for validating the XML data against the Schema XSD. I have more XML Files with same the schema. I have to used a for loop container which has an XML task for validate XML. The loop container gets the XML File into variables name "XMLFileName" which the loop current file, in turn, used by XML Task for validation.

XML task is configured in the option "Validate". I have provided the XML Data in variable name "XMLFileName" also get the name from the loop container and XSD file content File Connection. XML Task stored the result in the another variable name "OKFormat". FailOnValidationFail property set to false.

It had the error when I run the package, the error msg as below:


Error: 0xC002F304 at XML Task, XML Task: An error occurred with the following error message: "Data at the root level is invalid. Line 1, position 1.".

Error: 0xC002928F at XML Task, XML Task: Property "New Source" has no source Xml text; Xml Text is either invalid, null or empty string.

Task failed: XML Task

After that, I had to change the source type from Variable to File Connection, and had to test fixed to some xml file it had ok for validate the XML file againt XSD.

I don't know this is the wrong setting or bug of SSIS, anyone can guide me through.

SSIS - How To Set ServerName And DatabaseName At Run Time Inside FOREACH LOOP?

Jan 14, 2006

I am new to SSIS world, so my question is very basic.

Setup:

In a company I work for we have 12 SQL servers each running between 1 and 3 databases with anywhere between 10 to 20 tables. I need to query some of these tables and merge results to the destination database.

The list of all these tables is stored in the separate table <SOURCES> of the following format [ServerName,DatabaseName,TableName]. Tables of my interest have identical structure (same columns) accross servers and databases.

Question:

How can I loop over servers and databases specified in <SOURCES> to run otherwise identical query against these tables?

I can easily retrieve [ServerName,DatabaseName,TableName] from <SOURCES> as string variables using FOREACH loop. The problem is now - how do I use string variables to set up Server, Database and Table name at run-time?

Thank you

SQL 2012 :: Pass List Items To Stored Proc As Comma Separated Parameter - Foreach Loop

Feb 11, 2015

I have a multiselect checkbox list in my UI. I pass the list items to my stored proc as comma separated parameter and then I have a function which converts this parameter to a table with separate rows.

E.g. : a,b,c,d

Converted to result table

result
a
b
c
d

I want to insert each row of the result table into another table. How to do that.

E.g., the table after the function is :

CREATE TABLE #result
(
Subject varchar(100)
)

insert into #result values ('a')
insert into #result values ('b')
insert into #result values ('c')
insert into #result values ('d')

So the pseudo code is something like

for each row in #result

insert row into another table

Flatfilesource(s) In A Loop

Jul 9, 2007

I am trying to design a package to import the data of several .tx files into a table in sql server.

1) I created an execute task that truncates the sql server table i.e. truncate table tblContacts

2)
Placed a forrloop container with enumerator: foreach file enumerator
Folder points to the folder that holds the txt files
file: *.*
filename: fully qualified
variablemapping: User::FileName with Index 0

3)
placed a data flow task inside the forloop
this dataflow task has the following dataflow:
FlatFile Source: connection manager is pointing to one of the txt files
OLE DB Destination to place the txt data into tblContact in the database.

The question:
when the package is run, the tblContact gets populated only from the first txt file, i.e. the one which I placed in the flatfilesource connection manager.
How can I allow several files in the flatfilesource, instead of the one I have now...

Thanks

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.

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 File - Filename Mask

Dec 20, 2007



Hello

I'm using the ForEach File task and masking the files I want to process as ABC??.TXT.
It all works well until I drop a file there like ABC12 Copy.TXT, which I don't expect to be process, but the loop still picks it up. Am I using the wrong wildcards?

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....

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.
