Flat File-connection: Tuning Of The Data Types
May 25, 2007
Hello everybody.
I have a problem with "Flat file"-connection, which I cannot understand at the present. Here is the issue: I've got an ASCII-file containing 233898 lines. I try to read this file in two different packages using two different connections. In the first connection I used default data type - DT_STR of length 50, in the second one I used "Propose types..." feature (with 2000 samples) to detect types which are better matching the reality. And, when I try to load my data, the first connection reads exactly 233898 lines from the file, the second one 203898. Somehow it skips 30000 lines unloaded.
I tried to observe the error output for the second connection - everything goes smoothly and problemless. But somehow those 30000 lines are missed.
Has anybody experienced such a situation? Is the issue known?
Thanks in advance,
A.G.

This question is around how we can get the data types and lengths populated into the flat file source columns.
In Connection Manager, you have your flat file defined. You can choose "Suggest Types...", and the minimum lengths and correct data types will be returned from within the data in the flat file.
Is there some way to automate this data type definition, but coming from the other direction (coming from the destination table that we are loading)?
For example, you have mapped the columns that will be loaded. Can you then reverse engineer the data types and lengths for the columns in the flat file from the destination table?
TIA

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?

Hi,
I have a flat file that contains 2 types of records - Dev and production. The Dev will be noted with an D and the Production with a P. These records are different - The dev records are in a different order and contain different info then the Production. I need to use SSIS to import the data into 2 different SQL Tables. How to do this?
Can any one help me
Thanks in advance

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. Â The first time through the ForEach loop, the destination file is updated. Â The second time is when this error pops up. Â 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.

Hi,
I've just started looking at SSIS and have encountered what should hopefully be a simple problem to solve. I have a pipe-separated source file that looks like this (I've added Line numbers for simplicity):
Ln 01: HDR|FEED_CODE|31-MAR-2006
Ln 02: Tom|100|Jones|ZZ1 1ZZ|USA
Ln 03: Tom|200|Singer|
Ln 04: Tom|305||Red|Porche ||Lanzarote |Apple|Carrot| | |
Ln 05: Dick|100|Van Dyke|ZZ1 1ZZ|USA
Ln 06: Dick|200|Actor|
Ln 07: Dick|305||Blue|Ford||California |Tomato | |||Beef
Ln 08: Harry|100|Houdini|ZZ1 1ZZ|GBR
Ln 09: Harry|200|Escapologist|
Ln 10: Harryk|305| |Green ||Triumph |Poland|Banana|Sprout| | |
Ln 11: TRL|9
In addition to a header and footer records, this file contains three record types for each person.
Record types are identified by the second column.
Each record type has a different number of columns:
Type 100 has 5 columns
Type 200 has 4 columns
Type 305 has 12 columns
The Row delimiter for all records is the {CR}{LF} character
I've set up a flat file input source and specified {CR}{LF} as the row delimiter for both header and data rows and the "|" character as the field delimiter.
It appears that SSIS is assuming that because the first data row has 5 columns, then everything must fit that format too. So the {CR}{LF} character that separates lines 02 and 03 is interpreted as text rather than a separation character and all remaining | field separators after 305 are interpreted as text containing in the fifth column. SSIS is also complaining that the last row is incomplete.
A bit like this (I've used tildes to indicate column separation):
Tom~100~Jones~ZZ1 1ZZ~USA
Tom~200~Singer~{CR}{LF}Tom~305||Red|Porche ||Lanzarote |Apple|Carrot| | |
I've seen one other reference to this behaviour but the response seemed to be SSIS doesn't know which columns are missing. In this scenario, we don't have missing columns, rather, we have different types of record in a single file. in DTS I would effectively parse the file once for each record type thus:
if cStr(DTSSource("Col002")) = "100" then
DTSDestination("in_Name") = trim(DTSSource("Col001"))
...
Main = DTSTransformStat_OK
else
Main = DTSTransformStat_SkipInsert
end if
...not the most efficient solution I know but the load only runs once a month so this was an acceptable workaround.
DTS was never this fussy but I'm sure this is user error rather than an SSIS limitiion. Can someone please put me straight?
Many thanks,
Greg

I'm using SSIS to import seven flat files (each containing a different record type) into a staging database. This part was easy.
Now I need to export the records from all seven tables into a single flat file structured in a nested hierarchy using common keys. (This format is required by the vendor for loading data into a new system).
I could use some ideas on the data transformations needed to combine all seven record types into an hierarchical record set which can then be written to my Flat File Destination. I'm currently looking at an article on SLQIS.com ("Handling Different Row Types In The Same File") which seems close to what I need, but they are importing (ref: www.sqlis.com/54.aspx ). I'm not sure if I should just reverse this for export or use something different. Any comments are appreciated.
Diagram of Record Hierarchy
typeA (parent key, ...)
typeB1 (parent key, childSet key, date, ...)
typeB2 (parent key, childSet key, ...)
typeC (parent key, childSet key, ...)
typeD (parent key, childSet key, ...)
typeE1 (parent key, childSet key, date, ...)
typeE2 (parent key, childSet key, ...)
The record types B1 through E2 form a complete set. Each set has it's own unique child-set key. There may be one or more sets for each typeA record (although it's possible that typeE records don't exist in the most recent set).

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 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)
71167300 71167296
70329000 70329000

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);
}

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

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

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.
Any idea on how to fix it is appreciated?
Thanks in Advance.

Hi All,
I have a requirement wherein I have to read the data from a "|" separated flat file. Each row is specified this way...
<row>Data1|Data2|Data3</row>
<row>Data1|Data2|Data3</row>
<row>Data1|Data2|Data3</row>
<row>Data1|Data2|Data3</row>
.
.
.
.
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?
Thanks,

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?

(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 ?

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
