Flat File Connection Is Skipping Columns
Jan 25, 2007
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.
Any ideas on how to make this work?
Thanks,

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.....
Regards,

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.

Dear fellows,
I know that I think as sql2k programmer-dba yet but I can€™t avoid.
I€™ve got Flat File Connection Manager Editor dragged with a text file as €˜ragged right€™ format and CRLF as header row limiter. When from properties page and Columns option I€™m going to alter just a few colums I am not be able.
It seems that you must erase all of them in order to define one or two. And in the case you€™d have 50????
When I ran sql2k DTS designer did that without problems, alter columns again and again.
As far as I know it€™s a lose of flexibility, or not? Or is there any way for do that without deleting nothing else?

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 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
oRead = oFile.OpenText(Me.Connections.FileConnection.ConnectionString)
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.
Any thoughts as to what I am doing wrong?

I need find out the number of columns in flat file before i process that particular file.I have file name in @filename variable and file path is @filepath variable.But do not not that how i will check the column name in before i will process that file.
@filePath = C:DatabaseSourceFilesCAHCVSSourceFiles
And i am using for each loop container to read the file one by one and put the file name in @filename variable.and my file name like
Product_20120607060930.txt
Product_20130708060930.txt
[code]....
Now what i have to do is i need to make sure that ID,Name,City,County,Phone is there in flat file.if it is not there then i have to send mail to client saying that file is not valid.I need to also calculate the size of flat file.

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 €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?

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

Hi,
I'm attempting to use a variable to define the file name in my flat file connection (for error files in my SSIS package).
I have it defined as follows:
@[User::ValidRootFolder]ConditionConditionSourceError.csv
However it throws an error 'the filename, directory name, or volume label syntax is incorrect'.
If I put the value of the variable in explicitly it works, so I know my variable name is correct - am I just not calling the variable properly?
Thanks

I have a database app, and we're implementing various data export features using SSIS.
Basically, it's a couple of straight extracts of various recordsets/views, etc. to CSV (flat files) from our SQL Server 2005 database, so I'm creating an SSIS package for each of these datasets.
So far, so good, but my problem comes here: My requirements call for users to select from a list of available columns the fields that they want to include in their exported file. Then, the package should run, but only output the columns specified by the user.
Does anyone have any idea as to the best way to accomplish this? To recap, at design time, I know which columns the users will have to choose from, but at run time, they will specify the columns to export to the flat file.
Any help or guidance here is greatly appreciated

Please leave feedback for Microsoft regarding this problem at https://connect.microsoft.com/SQLServer/feedback/ViewFeedback.aspx?FeedbackID=126493
Ok I'm sure it just me, SSIS has been great so far....but how can you import a straight CSV file with and uneven column count.
For example: (assume CR LF row delimiter)
The,Quick,Brown,Fox,Jumps
Hello,World
This,is,a,test
"Normally" I'd expect this
| Col1 |
| Col2 |
| Col3 |
| Col4 |
| Col5 |
The
Quick
Brown
Fox
Jumps
Hello
World
NULL
NULL
NULL
This
is
a
test
NULL
Ok but what we get is the row delimiter is ignored in preference for the column delimiter and the row delimiter gets sucked into the column and the next row starts to get layed down.
So we get
| Col1 |
| Col2 |
| Col3 |
| Col4 |
| Col5 |
The
Quick
Brown
Fox
Jumps
Hello
World{CR}{LF}This
is
a
test
I'm I not seeing a tick box somewhere that says "over here if you want to terminate a row on the row delimiter even if all columns aren't full and we'll pad NULLs in rest of the row columns which you can fix in the flow transformations"
I'm sure it's there.....help!
(By the way SSIS team, great job on the package love using it)

Hi,
I have a dataflow task with two components: OLE DB source --> Flat File destination
In the OLE DB source, I am accessing a view, not a table.
However, when I attempt to map the view's input columns to the flat file destination columns, the screen is completely blank. There's none of the usual drop downs that let you select the column name, nor can I drag and drop the input column from the upper pane to the lower pane.
Is there a trick to doing this?
Thanks

I need to create a number of flat files, all with the same layout and sourced from the the same table, but with different criteria.
The first set of (three) flat files file is created out of a simple Conditional Split transformation: If Source Table row number > 40,000 route to File 3; if row number > 20,000, route to file 2, otherwise route to file 1. This gives me 20,000 rows in files 1 & 2 and the remainder in file 3.
I also want to create a fourth flat file by joining the Source Table with a sample table and selecting only those rows where the Customer numbers match. I'm currently doing this in two stages: An Execute SQL Task performs the join and inserts the selected rows into a Destination table (identical layout to source table), and then a simple data flow moves the rows from the Destination table into the fourth flat file.
My problem is that the order of the columns in the first three flat files is different from the fourth file. I've tried creating the fourth flat file with a single data flow using a Merge Join transformation which didn't work because the tables aren't sorted in the correct sequence, and I couldn't get an OLE DB Command transformation to work either.
I'm not sure why the column order of the 4th file should be different seeing as how its contents are sourced from the same Source table, but is there a cunning way of setting this up so that the columns end up in the same order?

I will be receiving a CSV daily where columns within the file will change. The column order and number of columns can change daily. I need a way to read in the header from the csv and create a flat file connection that reflects the columns listed in the header. Â
Is there an easy way to do this using a script task? I have already read the header into a table but I have been unable to create the dynamic file connection.

I have a flat file data source and SQL Server destination data flow. Only a subset of columns from the source are mapped to the destination. During execution SSIS returns DTS pipline warnings for every unmapped source column. Is some kind of transformation the only way to get rid of these warnings?
Also this data flow subsequently returns an error: [SQL Server Destination [1293]] Error: An OLE DB error has occurred. Error code: 0x80040E14. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E14 Description: "Could not bulk load because SSIS file mapping object 'GlobalDTSQLIMPORT ' could not be opened. Operating system error code 2(The system cannot find the file specified.). Make sure you are accessing a local server via Windows security."
I'm researching this error, but if anyone is familiar with it your advice would be appreciated. Thanks.

I'm new to SSIS, and trying to automate data imports from text files. The text files I'm importing always contain a fixed set of columns, or a subset of those columns. If I include a subset of columns in the import file (and exclude others), the data doesn't import...I assume because the actual file doesn't include every column defined in the flat file source object?
Is it possible to accomplish this without dynamically selecting the columns, as indicated here: http://msdn2.microsoft.com/en-us/library/ms136020.aspx

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

Hi all,
I am facing a problem on validating the data from a flat file while inserting the data into the destination table of sql server 2005 database. In my package, i have to validate the input data whether the values are coming as null or not, before inserting into the destination database. The flat file may not contain data for all NOT NULL columns. I have to find out that row(s) and reject the record. If the rows are coming as Null for the Not Null columns, the OLEDB Destination throws OLEDB exception for the constraint.
To resolve this, i have an script component in data flow, to check whether the input data is coming as null. I have added the output column of boolean type to the script component, it will be assigned to TRUE when there is null for the Not Null column in the script.
And in the follwing conditional split, i am checking the flag for TRUE to reject the record.
Is there any other way to handle this validation?
Regards
Madhav

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"
oConnection = package.Connections.New("DTSFlatFile")
oConnection.Name = filename
oConnection.ConnectionProperties.Item("Row Delimiter").Value = vbTab
