File Connection Act Differently Than Flat File Connection For Expressions?
Jun 26, 2007
I am thinking I must be doing something wrong..
I have dozens of packages that work as follows (high level... not listing all the steps just those relevant to this question)
- Get list of files in directory
- Join list to list of already imported files
- Those not imported put into an ADO.Net object
- Loop through ADO.Net record (which contains the filename) and import each file.
I just set the connection string of the flat file to be the variable in the loop (expressions.. connection string). Pretty standard stuff. Now I tried to do the same with a file connection (not a flat file) becuase I have a source that is from a mainframe and I had to write a custom source script and its not working. Basically the source script uses
And it opens the same file over and over (not ever changing as the ConnectionString expression changes like it does for flat files) and imports it even though I have verified the loop is correctly looping through all the different files.
I am testing SSIS and have created a Flat File Destination. I defined the Flat File Connection as New for the first time and it worked fine. Now, I would like to go back and modify the Flat File Connection in the Flat File Destination Editor, but it allows only to create a New connection rather allowing me to edit the existing one. For testing, I can go back and create a new connection, but if my connection had 50-100 columns then it would be an issue to re-create it from scratch.
I have a situation where a tab limited text file is used to populate a sql server table.
The tab limited text file comes from a third party vendor. There are fixed number of columns we need to export to the sql server table. However the third party may add colums in the text file. Whenenver the text file has an added column (which we dont need to import) the build fails since the flat file connection manager does not create the metadata for it again. The problem goes away where I press the button "Reset Columns" since it builds the metadata then. Since we need to build the tables everyday we cannot automate it using SSIS because the metadata does not change automatically. Is there a way out in SSIS?
Problem: ColA (Source) Rounding error to PARTY_NO (Destination) I have a field of text of in a flat file that the flat file connection manager Source picks up correctly €œ70000893€? However when it gets the OLE DB Connection Destination the data has changed to 70000896. That€™s before its even Written to the database. The only clue that something is wrong in the middle is the great Data viewer shows the number as 7.000009E+07 Other clues looking at the data it appears there is a rounding error on only the number that dont end in 00 ColA (Source) PARTY_NO (Destination) 71167300 71167296 70329000 70329000 70410000 70410000 Any ideas people? Thanks in advance Dave
Hello Experts, I am createing one task (user control) in SSIS. I have property grid in my GUI and 2 buttons (OK & Cancle). PropertyGrid has Properties like SourceConnection, OutputConnection etc....right now I am able to populate Connections in list box next to Source and Output Property.
Now my question to you guys is depending on Source Connection it should read that text file associated with connection manager. After validation it should pick header (first line of text file bases on record type) and write it into new file when task is executed. I have following code for your reference. Please let me know I am going in right direction or not.. What should go here ? ->Under Class A
I have a package A which is copied from another existing package B as most of the data structure and ETL mappings are same.
What I need to change in Package A is to change the file in Flat File Connection Manager. I can change it in the conneciton manager editor. However, it is automatically changed back to the previous one everytime when I try to Save All or run the package.
I also tried to copy/paste this Flat File Connection Manager in the same package but samething happen. The package file is not set 'Read Only" so anything else can Saved well except for the File name in connection manager.
Is this a bug? It would be very appreciated if anyone can give me any idea about this.
What happens is that the flat file connection non of the columns can be altered
you can set them in other ssis packages but not in the one that you want to use and when it comes to changes the flat file complains that not a correct file is set, even though there is one set,
and when it comes to altering a flat file source it complains that it can not find the connection and the database destination can not find the meta data BUT
when it is run it works perfectly,
so what i have had to resort to is making the part of the dts package in another package and then copying it accross
I'm trying to generate a DTS Package with VB.Net using the Microsoft DTSPackage Object Library and and the Microsoft DTSDataPump Scripting Object Library I have to load csv files into SQL tables. I could generate both a SQL connection and a FlatFile connection and the transformationtask.
When I look at the transformationtask and click on the transformation tab I get this error
"Incomple file format information"
The problem is I don't find where I could set the FlatFile connection properties like "Text Qualifier" and "row delimiter"
I tried this but it still shows CRLF as row delimiter when I look at the generated DTS Package
Dim oConnection As DTS.Connection2 Dim package As DTS.Package2 Dim filename As String filename = "myfilename.csv"
I would like to set up the flat file connection manager that would take any file name that starts with "test" and then it could be anything after that. Something like test_*.txt.
I have a SSIS package schaduled for data import, the source file is a flat file connection (*.CSV).
The file is located on a sharing folder over network, the problem is that file name changed daily accordance with date like (data 7-02-2008.CSV), the very next day file name will be (data 8-02-2008.CSV)
How to link such files so that we dont have to change file name in our SSIS package ...?
All, I have a SSIS package that can be run outside SQL Server Agent, but fail with SQL Server Agent for the same user login. The packages are saved in the sql server database with Windows Authentication. The protection level I used is the default one: €œencrypt sensitive data with user key€? The packages have a step to dump data into a flat file destination. The error message is €œCannot open the datafile€? on the local drive that the user has access to.
. . . . I am specifying the row delimiter as : </row>{CR}{LF}<row> When I create Flat File Connection and when I see the preview of columns...in the first row "<row>" remains and in the last row "</row>" remains...
I am trying hard to sort out and remove these extra string but unable to do so...
Please let me know how to approach this? How should I specify the Row Delimiter?
Description: The file name "\fhfgy678c$wtswts_Adjud_05082008.txt" specified in the connection was not valid. End Error Error: 2008-05-08 10:04:14.67 Code: 0xC001401D Source: ETL_wts Description: Connection "Flat File Connection Manager" failed validation. End Error DTExec: The package execution returned DTSER_FAILURE (1). Started: 10:04:13 AM Finished: 10:04:14 AM Elapsed: 0.781 seconds. The package execution failed. The step failed.
I can run a package that has flat file connection... I can run it withoutany erros in BI studio.. but I am keep getting the above erro after I depoly the package and run as a sql agent job.. I just can not figure out why I am getting this error.. any Idea.. please help..
Hi All, I am using flat file connection manager to create a text file. I could not find any way to set the file location (folder) dynamically such as using variable, expression etc, Is there any alternative I can use to achieve this? I really don't want to hard-coded the file location as it may differ in production environment. Thanks in advance.
As I have a file whose delimiters can be different. I have need to change the delimiters and filename programatically.
I have come across a way to change the filename using the inbuilt expressions setter. Howver the columns are not listed, possibly because they are on the advanced tab and theoretically each column delimiter could be different.
Will I have to do this through a script or is there an easier method?
Hi, I want to read only the first row in flatfile. I do not see this option on "Flatfile connection manager editor" setting wizard. Any work around for this?
I've tried all of the different column delimiters, but apparently this file does not use any of the built-in delimiters, such as tab. I think there are just blank spaces between the columns.
I've requested that the file be comma-delimited instead, but in the event that this is not possible, how should I handle this situation?
I need to know how I can programmatically set a Flat File Connection Manager's Column Delimiter value.
The Data Warehouse project I am working on, receives daily information feeds that could contain one of two delimiters. Which is just dumb...anyways, as it is now we have two seperate Data Flow Tasks which handle these two delimiters. Currently we have a script taks that "sneak previews" each incoming flat file to determine which delimiter it has, and direct our flow to the correct Data Flow Task to handle it.
I do not want to have to maintain 2 DFTs. How can I get around this problem?
Even if there is a way to do this by passing variables/setting expressions in the Flat File Connection manager, I would do that. Does not necessarily HAVE to be a pure programmatic approach.
ANY help would be greatly appreciated!

I have a Dataflow with three componnets: 1. script component 2. script component 3. flat file destination
After I connected second script to the flat file destination and tryed to opend Flat File Destination Editor, a dialog with this message showed:
TITLE: Editing Component ------------------------------ The component is not in a valid state. The validation errors are: Error at Data Flow Task [Flat File Destination [76]]: The component locale ID has not been set. Flat file adapters need to have the locale ID on the flat file connection manager set.
Do you want the component to fix these errors automatically? ------------------------------ BUTTONS: &Yes &No Cancel ------------------------------
No matter which button I pressed, I was not able to work with flat file connection manager.
When I selected a file path in connection manager editor, I got an error "A valid file name must be selected". I tryed different files in differnet folders, but got the same error.
So I tryed to open some older working packages. On flat file destination componnent , when I clicked on tab "Mapping", recieved error " [Flat File Destination [51]]: Unable to access the acquired connections.",
Flat File connection manager showed "A valid file name must be selected". But althought these old packages seem to be broken in design, they a running OK.
I thought, that the problem could be in wrong expression for connectionString, but it still remains after removing it.
Please, could you give me advice, where could be a problem or what should I check?
I am programmatically creating a package in c#. I need this package to contain a flat file connection manager. I have been successfully able to create the connection manager with the following code:
Package p = new Package(); //New package
ConnectionManager cm = p.Connections.Add("FLATFILE"); //Add a flat file connection manager
cm.ConnectionString = "C:DevmyTestFile.txt"; //Set up the connection string
At this point, I want to configure the flat file specific properties of the connection manager (RowDelimiter, HeaderRowDelimiter, etc.). The problem is that the properties collection of the ConnectionManager object is read only. I think I could access the inner object of the connection manager and set the properties in the following way:
ConnectionManagerFlatFileClass ffClass = (ConnectionManagerFlatFileClass) cm.InnerObject; //Get the inner object
ffClass .RowDelimiter = "{LF}"; //Set the properties here Even if this would work, I do not like the solution b/c the BOL states that the ConnectionManagerFlatFileClass "supports the SQL Server 2005 infrastructure and is not intended to be used directly from your code". Does anyone know the "right" way to set these properties? Many thanks in advance! David
I have a flat file that I'm trying to bring in. I've mapped all the columns, and the first record comes out perfect. The problem is that its not recognizing end of line. When I preview it line one looks great, but line two has two square boxes before the actual next record begins and those boxes move over into the next column on the next record and so forth. The Format is Fixed Width, I have no text qualifier, header row delimeter is set to default {CR}-{LF}, and we're starting on row 2 as row 1 is garbage. Any ideas?
I was wondering if any others on this list are getting a bug with the Flat File connection object --where in both csv (coma delimited) or flat files (tab delimited) where strange characters(like two bold vertical lines) are appearing in the file viewer while setting up a connection forcing the CRLF to end in the wrong place. They look like two bold vertical lines
Im testing the same files with both the old DTS from SQL Server 2000 and getting no issues which tells me there is a bug in SSIS. Strange thing the bug does not happen with every file I receive, only a few. I€™m wondering if SSIS Flat File Connection object could be a little flaky with respect to how it reads files compared to DTS text connection object.

The Import wizard was used to create a package. The package simply reads a flat file and writes the columns to a SQL table. The package was added to and opened in an SSIS project. I would like to make several iterations of changing the flat file columns and their names. Most commonly the wizard would be run with the column names defaulted to [Column 0],[Column 1] ... Later the name will changed when the proper name is known.
I have been able to change the name of a column, but don't know how to synchronize the SQL table creation and the column mappings. Help please.
The data file contains column names in the first row. Excel imports the file correctly. I can see the tabs in UltraEdit32. But...the flat file connection just skips over a column. In the preview window, it appears to skip the column entirely.
However, when the data is imported, data from the non recognized column goes into a column that is mapped to receive data from another column shifting the data in to the next column.
I am using the CopyColumn and the SQL Destination controls.
What is the best way to deal with a flat file source when you need to add a new column? This happens constantly in our Data Warehouse, another field gets added to one of the files to be imported, as users want more data items. When I originally set the file up in Connection Managers, I used Suggest File Types, and then many adjustments made to data types and lengths on the Advanced Tab because Suggest File Types goofs a lot even if you say to use 1000 rows. I have been using the Advanced Tab revisions to minimize the Derived Column entries. The file is importing nightly. Now I have new fields added to this file, and when I open the Connection Manager for the file, it does not recognize the new columns in the file unless I click Reset Fields. If I click Reset Fields, it wipes out all the Advanced Tab revisions! If I don't click Reset Fields, it doesn't seem to recognize that the new fields are in the file?
Is it a waste of time to make Advanced Tab type and length changes? Is it a better strategy to just use Suggest Types, and not change anything, and take whatever you get and set up more Derived Column entries? How did the designers intend for file changes to be handled?
Or is there an easy way to add new fields to this import that I am overlooking? I am finding it MUCH more laborious to set up or to modify a file load in SSIS than in DTS. In DTS, I just Edit the transformation, and add the field to the Source and Destination lists, and I'm good to go. My boss isn't understanding why a "better" version is taking so much more work!
The standard flat file connection component does not handle flat files with different column counts on different rows. Since that's the type of file I have to read, I like to create a modified version of the flat file connection manager that can do this. I have found some info in how to create a connection manager. But I can't find anything that tels me how to build one that would be recognized by the flat file source dataflow component.
So how do you build an connection manager that can used by the standard flat file source component? Anyone ever did this or knows were to get the docs?
I know my problem is also solvable by reading the row into a single column and then using a script component to split them but that is not the solution I want.
I am having some issues with dts packages i have migrated using the package migration wizard.
One of the connection managers points to an execl flat file source.
I have not altered anything after the package migration, the conenction manager is using Native OLE DBMicrosoft Jet 4.0 OLE DB Provider.
When i test the connection i get the following error :
"Test connection failed becuase of an error in initializing provider. Cannot start your application. The workgroup information file is missing or opened exclusively by anotehr user."
Ok i am 99% sure this file is not being accessed by another user, the rest of the error is greek to me. Looking on the net for this error it has to do with access database security and having to sertup htm pages for IIS, i cannot findanything on this error relating to ssis connection manager.
