Can't I Dynamically Read From Any File? - Connection Manager Does Not Exist
Feb 23, 2007
I have a Parent package and a child package.
I have hard coded the value for the User::FilePath variable in the parent package.
I am mapping this variable to the value of the same variable in the Child Package.
I created a directory and sql file: "C: empsqlb.sql". I have verified that the path variable value is passed to the child package by using a Script task with a messgbox call.
How do I define an execute sql task to execute sql file: @[User::FilePath] & "sqlb.sql". I'm using this expression for the SqlStatementSource property. I have entered the OLEDB server information and specified the SQLSourceType = fileconnection.
However I get the error:
[Execute SQL Task] Error: Connection manager "D:
lewisdevZsqlb.sql" does not exist.
What am I doing wrong?

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

Within an SSIS Package, we are trying to change the connection string of an output file connection manager at runtime (used for package logging).
To do this, we have defined variables with package-level scope and set the connection manager connection string to this variable. The first step of the package is to set these variables. The second step begins the rest of the package operations (moving data). The package executes successfully, but the log file is never created/appended to.
When the package is debugged, I can verify that the variables are being set correctly in the script task and that the variable values are being passed to the connection manager data sources.
Any ideas why this isn€™t working?

I am pretty new to SQL Server 2005 and SSIS. I am trying to dynamically load files into SQL Server 2005 using files/paths contained in tables. I have a key table in my SSIS package that defines which files should be processed, some default values that will be associated with each file (ie CompanyKey and PeriodKey) and the file path (see below for example):
CompanyKey
PeriodKey
ProcessFlag
FileName
2
61
FALSE
2005TB200501.xls
2
62
FALSE
2005TB200502.xls
2
63
FALSE
2005TB200503.xls
2
64
TRUE
2005TB200504.xls
2
65
TRUE
2005TB200505.xls
2
66
TRUE
2005TB200506.xls
2
67
TRUE
2005TB200507.xls
2
68
TRUE
2005TB200508.xls
2
69
TRUE
2005TB200509.xls
2
70
TRUE
2005TB200510.xls
2
71
TRUE
2005TB200511.xls
2
72
TRUE
2005TB200512.xls
The package I am developing is supposed to loop through this table checking for files with ProcessFlag = TRUE. For those files, it will load all of the records/columns (prefaced with the company and period keys) into a common table.
Do I have to manually create data sources for each file or is there a way to dynamically define the connection and process the connection?
Any assitance you could provide would be greatly appreciated!
Thanks.

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

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)

Hi,
I tried to follow the widely talked about method to dynamically populate the connection string property of my flatfileconnection manager from a variable. I keep getting the following non-fatal error.
TITLE: Microsoft Visual Studio
------------------------------
Nonfatal errors occurred while saving the package:
Error at Package [Connection manager "FFCM"]: The file name ""C:ProjectsSSISHLoadTOutputOut.csv"" specified in the connection was not valid.
Error at Package: The result of the expression "@[User::CsvFullFileName]" on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property.
Here is what I am trying to do.
I have a foreach loop that iterates through a list of xml config files and reads the config information including the destination csv file name and does a data transformation.
So I created a flatfile connection to a csv file did my data mappings.
Created a package level variable to hold the destination file path
In the Flat file conn. manager's properties -> expression -> set the @[User::CsvFullFileName] (which even evaluates fine)
When I try to run the package I keep getting the above mentioned non-fatal error..I checked the path and it is valid. I even tried
the c:\projects\...notation and the UNC path notation...all seem to give the same error
Anyone experience this before ? any thoughts would be appreciated.
Thanks

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

Is there any real purpose to the File Connection Manager? Not the Flat File Connection Manager, just the plain old File Connection Manager.
I have one in my SSIS package because I thought it might make writing to a file easier. But from what I can tell, it doesn't really do much. I have to pull the file name from the connection manager and basically open and manage the file myself in my scripts.
I went this route because I have two scripts that write to the file in turn... one writing out parent records and the other inserting the child records after each parent.
The script looks like this:
Code Block
Dim outFile As String
outFile = Dts.Connections("TestFile.LDIF").AcquireConnection(Dts.Transaction).ToString()
Dim sw As New StreamWriter(outFile, True)
sw.WriteLine()
sw.WriteLine("dn: " & Dts.Variables("GroupID").Value.ToString())
sw.WriteLine("changeType: add")
sw.Close()
I have to close the connection every time because the other script uses the file. It seems that this is quite inefficient. Am I using the File Connection Manager incorrectly? What's a more appropriate way to do this?
I could open the file in a different script and store the StreamWriter object in a global variable, I suppose...
Thoughts, suggestions?
Thanks.

In the file connection manager, how do I specify a dynamic file name, using a variable?
Such as:
"c:myDir" + @[User::FileName]
When I attempt to do this, it says it's not valid. I certainly hope there is a way to do this!

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 There
This should be an easy one i hope.
I need to dynamically change the file name of my destination flat file connection everytime the package runs, obviously i do not want to edit the config file everytime.
I think the best way to do this is by a script taks that sets the connection manager filename property with a variable that i dynamically populate.
Is this the right way?
I just want to be sure that there is not an easier or better way to do this?
Thanx

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 !

Hello,
I am new to SSIS. Could someone please tell me how to make the Connection Manager use the connection string from the configuration file?
I am trying to have connection information set in one place for all the packages to use.
I have already created a .dtsConfig file based on my existing Connection Managers.
Do I need seperate dtsConfig files for each database?
Thank you.

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 :)

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?

Now If a put SSIS work Offline as True (I need this for some reason). Connection manager for File gives error as something --
"Connection manager for File connection failed with error code-0xc0014019,Connections cannot acquire connections while work offline is true."
But other connections of olddb work fine.
so do we have to change some more settings with file connection or with file connection we can't work offline?

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.

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,

I've discovered an issue with the text qualifier field in the file connection manager when upgrading a SSIS 2005/2008 package from a 32 bit platform to 64 bit platform runninn SQL Server 2008 R2 10.5.1600.
The package will convert <none> in this field to _x003C_none_x003E and therefore any package using the file connection manager i.e. import/export - common tasks on SSIS! will cause problems either with output data or imported data.
Simply replacing _x003C_none_x003E with <none> fixes the issue but ofcourse there can be many packages affected as a result.
Any existing/impending cumulative update for SQL Server 2008 R2 Standard that will fix the problem?double quote delimiters are converted to _x0022_ which I am assume by replacing with a double quote will fix the problem.

I have a package that I plan to run against about 700 databases to look for anomalies. I have several package variables in place that are passed in at runtime. One of them will hold the path and filename of the error log for the current database in process. I want each database to generate it's own error log for documentation and research purposes. However, when I run the package, it continues to use the path and filename that I entered when I created the File Connection Manager. I am trying to update that value in a Script Task by using the ConnectionManager class and setting the value for the "ConnectionString" property. This method is working for the OLEDB Connection Manager (which tells the package which Access database to process), but not for my File Connection Manager. Please help!

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.

Hi everyone
I´m 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
