Integration Services :: Modifying Flat File Connection Manager
Aug 18, 2015
URL....I'm having a problem with Integration Services Tutorials SSIS Tutorial: Creating a Simple ETL Package Lesson 2: Adding Looping (step 3).I can't add a variable to Sample Flat File Source Data.Right-clicking on the connection manager just shows two items of the property: File Name and File Path and nothing else.I am using MS Visual Studio Ultimate 2012. Does it have limitations? I've see screenshots where properties of flat file managers have many more options.

Can we disable a flat file connection manager in a ssis package just as how we can disable a OLE db task? When I try to disable the flat file by clicking on work offline its gets disabled which is what i expected , but when i close the package and reopen it again its again enabled , is this the way that a flat file connection manager works.

I have a requirement wherein I have to setup the flat file connection manager to accept columns on fly. Meaning I want to retrieve list of columns/column count from the database when the package is run and set the connection manager with those many columns.

I've developed a package that is working well at development machine from VS 2013 for a sample flat file. Also, over development machine, I've deployed it to SSISDB catalogue and even from there also it is running well for the same file.When the same package is deployed to production server's SSISDB catalogue database, it throws following error while processing the same sample flat file, “Unable to retrieve column information from the flat file connection manager”

I have a Data Flow Task within a ForEach loop container. The source of the flow is ADO.NET connection and the destination is a Flat File Connection. I loop through a collection of strings in the ForEach loop. Based on the string content, I write some data to the same destination file in each iteration overwriting the previous version. I am running into following Errors:
[Flat File Destination [38]] Warning: The process cannot access the file because it is being used by another process.
[Flat File Destination [38]] Error: Cannot open the datafile "Example.csv".
[SSIS.Pipeline] Error: Flat File Destination failed the pre-execute phase and returned error code 0xC020200E.
I know what's happening but I don't know how to fix it. The first time through the ForEach loop, the destination file is updated. The second time is when this error pops up. I think it's because the first iteration is not closing the destination file. How do I force a close of the file within Data Flow task or through a subsequent Script Task.This works within a SQL 2008 package on one server but not within SQL 2012 package on a different server.

I have one SSIS package that has FTP task which takes files from FTP and save on my local drive but i'm getting above error.
[FTP Task] Error: Directory is not specified in the file connection manager "User::ProcessingFileLocation".
In FTP Editor setting :
User::ProcessingFileLocation used SSIS variable and values sets to this is MYSERVERRaw Data
why getting this error?
when i mention direct path it is working fine BUT why not for variable.I'm using same path for other packages too they all are working fine.

I'm working in VS 2010 for SSIS 2012. I have a project whose deployment is done via project deployment to SSISDB. I've got a local flatfile connection manager within one of its packages. When I deploy I'm unable to override the file name property in either package configuration or job step configuration on the SQL Server. If the flatfile connection were at the project level, I could. Not sure of the rationale for this or maybe I'm doing something wrong.

created a very basic flow in SSIS: extracted table data through ole db connection, added multicast and as end result i created a flat file destination (with .txt file) and a ole db destination.
My question is; how can i delete the .txt file before executing the flow again? Want to avoid that the .txt file has duplicated rows after a second execution of the flow. Is it possible to use scd component or is this way to complicated? A for each loop?
i need a similar solution for the data that will be transported through the ole db destination task....

I need to process a 2012 Excel file. In SSIS Connection Manager, I am only given an option until Excel 2007 version. When I use this in my connection for Excel Source, I am prompted with this error when I attempt to select the name of the sheet:
"Could not retrieve the table information for the connection manager 'Excel Connection Manager'.
Failed to connect to the source using the connection manager 'Excel Connection Manager'"
Also my Run64BitRuntime is set to false.

Hi,
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.
Did someone else faced this issue?
Thanks,
AQ

Hi,
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?

I have a Rounding error: Between flat file connection manager Source & OLE DB Connection Destination (SQL Server 2005) in my Dataflow.
File looks like this lets call column names Col A,B,C,D
70410000 RD1 1223631.92 196042.42
70329000 ICD 11025.84 3353.88
71167300 COL 104270.59 24676.96
flat file connection manager settings: first row Column names then Advanced tab Col A float , Col B float , Col C string ,Col D float ,
OLE DB Connection Destination (SQL Server 2005)
CREATE TABLE [dbo].[PT_CUST_ABR](
[PARTY_NO] [float] NULL,
[PARTY_NAME] [varchar](75) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[TELECOMABR] [float] NULL,
[GENIABR] [float] NULL,
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 70000893?
However when it gets the OLE DB Connection Destination the data has changed to 70000896. Thats 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

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.

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?

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
public override DTSExecResult Execute(Connections connections, VariableDispenser variableDispenser, IDTSComponentEvents componentEvents, IDTSLogging log, object transaction)
{
//Some code to read file and write it into new file
return DTSExecResult.Success;
}
public const string Property_Task = "CustomErrorControl";
public const string Property_SourceConnection = "SourceConnection";
public void LoadFromXML(XmlElement node, IDTSInfoEvents infoEvents)
{
if (node.Name != Property_Task)
{
throw new Exception(String.Format("Invalid task element '{0}' in LoadFromXML.", node.Name));
}
else
{
try
{
_sourceConnectionId = node.Attributes.GetNamedItem(Property_SourceConnection).Value;
}
catch (Exception ex)
{
infoEvents.FireError(0, "LoadFromXML", ex.Message, "", 0);
}
}
}
public void SaveToXML(XmlDocument doc, IDTSInfoEvents infoEvents)
{
try
{
// // Create Task Element
XmlElement taskElement = doc.CreateElement("", Property_Task, "");
doc.AppendChild(taskElement);
// // Save source FileConnection
XmlAttribute sourcefileAttribute = doc.CreateAttribute(Property_SourceConnection);
sourcefileAttribute.Value = _sourceConnectionId;
taskElement.Attributes.Append(sourcefileAttribute);
}
catch (Exception ex)
{
infoEvents.FireError(0, "SaveXML", ex.Message, "", 0);
}
}
In UI Class there is OK Click event.
private void btnOK_Click(object sender, EventArgs e)
{
try
{
_taskHost.Properties[CustomErrorControl.Property_SourceConnection].SetValue(_taskHost, propertyGrid1.Text);
btnOK.DialogResult = DialogResult.OK;
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
#endregion

Hi,
I have a flat file, comma-delimited, with strings in double-quotes.
In the connection manager for the file, I have specified that the Text Qualifier = ""
However, in the preview tab, it still shows the strings as surrounded by the quotes, e.g. "mycol1" whereas it should show mycol1 without the quotes.
Next, when I examine the data in the database after the load, it's messed up there also.
"mycol1" ends up in the database as "mycol1
"mycol2" ends up as "mycol2
This is not right.
I have format set to delimited, header row delimiter crlf, etc.
Any ideas?
Thanks

Hi,
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.
Thanks,
Jenny

I use SQL Server 2012 and visual studio 2010.I created SSIS Project with task "Execute Package". Control flow view as: Package1 (execute package) -> Package2 (data flow).Data flow in Package2 view as: ADO.NET source -> ADO.NET destination.
When I started Package2, it's work. I havn't errors.But when I started Package 1 I have error "Unable to get managed connection from the Connection Manager runtime". In execution log I see that ADO.NET source produced this error on verification stage. Package failed on verification stage, not on execution stage.Why when I started Package 2 it work, but when I started Package1 (and Package1 started Package2) it failed?

Hello,
Does anybody know, how to load unicode text file using Flat File Source Task?
I set "unicode" option on the general tab of the Flat File Conn. Manager.
(my text file is comma delimited, the default row delimiter is {CR}{LF})
but on the Column tab I see only one row in one column (I have several rows and columns in the flat file).
How to see them all ?
I appreciate any help !

Hi,
I am having problems setting up columns in a flat file connection manager.
The text file I am trying to parse is in this format:
col1 col2 col3 col4 [] col1 col2 col3 col4 [] col1 col2 col3 col4
where [] = {LF}
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?
Thank you

Hello,
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!
Feel free to email me at ccorbin@topcoder.com with any questions, or leave me some good news here :)
THANKS!

Hi,
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?
Thanks a lot

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?
Thanks,
Parag

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 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.

Hi There
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.
PLEASE HELP.
Thanx

Hi everyone
Im using the Flat File Connection Manager to access a flat file, tab delimited. The flat file has 200 columns, and when I'm editing the columns, I only preview columns from 0 to 97.
Does the flat file connection have a column number limit? How could I increase it?
Thank you for your answer.....

Guys
Another question regarding the frustrating SSIS stuff. Basically when I used to use a DTS task to import a flat file (comma delimited) into the database it worked fine no problems, however, for some reason the same approach in SSIS means that any string values in the file are automatically delimited with double quotes, even though I am specifying <none> as the delimitation. I have also changed the fields so that the the TextQualified is set to false.
This causes a problem because all of the information stored in the database (done by a stored procedure) contains these stupid quotes.
Is there something I am missing or haven't done correctly to get rid of the quotes
Thanks

I have an existing SSIS package created on another workstation. It connects to and updates data in a DB2 database. I'm only making one very minor change to the package, so I want to change this package as little as possible.When I try to open the existing db2 connection manager in the package on my workstation, I get 'The specified provider is not supported.Please choose different provider in connection manager'.
On the properties box, I get the following on the connectionString for the existing connection manager (data source and userid changed to "private"):Data Source=PRIVATE;User ID=private;Provider=IBMDADB2.DB2COPY1;Persist Security Info=True;
I tried loading the 32 and 64 bit db2 drivers (but I may have done something wrong). I still couldn't get the original db2 connection manager to open, I tried to add a new connection manager,
Data Source=PRIVATE;Provider=IBMDADB2 Advanced Page..This has 'Provider=IBMDADB2 Advanced Page.;' instead of Provider='IBMDADB2.DB2COPY1', and doesn't let me enter a userid and password, which I need to be able to do.

I need to add the current date to the end of the filename of a flat file at runtime.
This was previously done with ActiveX script in SQL Server 2000.
oConn = DTSGlobalVariables.Parent.Connections("FlatFileConnectionManagerName")
oConn.DataSource = sNewFileName
oConn = Nothing
I would really appreciate if someone could give me some information on how to achieve this in SQL Server 2005.
Thanks in advance!

I have a gazillion text files, each with dozens of records. The fields are pipe-delimited, the end of each record is marked by ASCII char code 28.
example:
05|11900307|1|CO|Gervais|Neil|NG8880|F|540|0|0|0|T|0|||F|||F 05|11900307|2|AO|MARSHALL|BRAD|BM7843|F|510|60|0|0|T|0|||F|||F
The " " is the Chr(28). The line above should parse into 2 rows...
**** time passes ****
An interesting discovery - if I paste that " " directly into the row delimiter box, without quotes or brackets, I get two records!
So I found at least one answer.
Is there another?
TIA
