I am trying to export an OLEDB source (from a stored procedure) to an UTF-8 flat file, but am getting the following error:
[Flat File Destination [2]]
Error: Data conversion failed. The data conversion for column "name" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
The name column is defined in the stored procedure as nvarchar(30).
In the advanced editor of the OLEDB source, I have the AlwaysUseDefaultCodePage set to true and the DefaultCodePage set to 65001.
In the advanced editor for the flat file for the External Columns and Input columns, the Data Type is Unicode string [DT-WSTR] with a length of 30.
The connection manager for the flat file has the Unicode checkbox un-checked and the Code page is: 65001 (UTF-8).
I am stumped right now and any help would be appreciated.
Thanks,
David
EDIT:
I added a redirect of errors and truncations to a flat file destination but nothing was sent to the file.
Also, when I have a data viewer on the OLE DB source it comes up with all the records.
The data viewer for the Destination also shows all the records. The length of the name in both viewers is 30 characters (from Excel).
I gave up on getting the data flow to work and coded a C# script task instead.
I changed the output of my data flow to produce a Unicode file by checking the Unicode check box in the flat file connection manager.
I then have the new C# script read the Unicode file one line at a time and output the line to another flat file using Encoding.UTF8 adding a new line character at the end of the line variable.
After the new file is created, I delete the input file and rename the new file to be the same path and name as the original input file. This is also done in the C# script.

I have an SSIS job to import data from a flat file into an SQL Server table. I'm having an issue regarding the encoding of the source file and destination table.
The file is an UTF8 encoded CSV file with some standard accented latin characters (ãóé, etc). My destination table is defined as having the Latin1_General_CI_AS Collation, which means I can manually insert the following text with no problem: "JOÃO ANTÓNIO".
When I declare the Flat File source, it automatically determines the file as having the 65001 code page (UTF-8), and infers the string [DT_STR] data type for each column. However, the SSIS package automatically assumes the destination table as having the 1252 Code Page, giving me the following error:
Validation error. <STEPNAME>: <STEPNAME>: The code page 65002 specified on output column "<MYCOLUMN>" (180) is not valid. Select a different code page for output column "<MYCOLUMN>".
I understand why, since the database collation is defined as having that Code Page. However, if I try to set the Flat File datasource as having the Latin1 1252 encoding, the SSIS executes but it imports characters incorrectly:
JOÃO ANTÓNIO (Flat File)-> JOAO ANTÓNIO (Database).
I have already tried to configure the flat file source as being unicode compliant, but then when after I configure each column as having a unicode compliant data type, i can't update the destination step since SSIS infers data types directly from the database and doesn't allow me to change them.
Is there a way to keep the flat file source as being CP 1252, but also importing the correct characters? What am I missing here?
Thanks to Larnu's comment i've been able to get around this problem.
Since SSIS doesn't allow implicit data conversion, I needed to set up a data conversion step first (Derived Column Transformation). Since the source columns were already set up as DTSTR[65002], i had to configure new derived columns form an expression, converting from the source code page into the destination code page, with the following expression:
(DT_STR, 50, 1252)<SourceColumn>
Where a direct cast to DT_STR is being made, stating the column will have a maximum size of 50 characters and the data will be represented with the 1252 code page.
I am running an SSIS file that read from DataSource to convert it into Image File
for that I am using "Export Column" and everything seems to be alright except that generated files cannot be opened (as they are not images)
The file name is ending with JPG but the end result a file with real size but cannot be opened
The source column in of type DT_NTEXT
I wonder what could be wrong that cause this
I am creating a SSIS package using MS Visual Studio 2012 Shell with .Net framework of 4.6.01055. The SSIS package has a Data Flow task with Flat File Source, Data Source Row count, Final Data Set count and OleDb destination tasks. It connects to a SQL Database and I have checked to see that my connection has been tested.
I have a flatfile connection manager which picks up a text file. On the Preview section it only shows the header columns in the flat file connection manager editor. The error message is only at warning level with the following message: [Flat File Source [10]] Warning: The end of the data file was reached while reading header rows. Make sure the header row delimiter and the number of header rows to skip are correct. The file itself has a total of 19 rows with the first being the header row.
I have spaces in the header names of the origin file. So on that file I edited to have no spaces on the final column. That did not cure the issue. The last column is a date but I am designating as OutputColumnWidth of 50 and datatype as string[DT_STR]. I have the Row delimiter as {CR}{LF}. I have the column delimiter as {|}. When run the package file name does not change.
In the General section of the editor under locale = English; Unicode is not checked; Code Page = 1252 (ANSI-Latin1); Format = Delimited; Text qualifier = none; Header row delimeter = {CR}{LF} (I have tried just CR or LF as well); Header rows to skip=0 (I have tried 1 as well since there is only one header row); and I have checked Column Names if the first data row.
Why am I not getting data in my preview section? And why is it thinking I only have a header?
It seems to me that your text file does not have a matching EOL marker, and so SSIS never splits the lines (and treats the file as just having one big header).
Try opening the file in a text editor that lets you see the EOL marker. I know that NotePad++ can do this for you.
NotePad++ will also let you change the file's encoding as well, in case that is also a problem.
NB: The problem could also be that you are not specifying a correct column delimiter. If the delimiter you specify in SSIS doesn't match characters in the file, then SSIS will also think that you have a single header row where everything is in the first column.
Just to add to the other answer:
I had the same problem, when i opened the file in notepad, it became clear that there was a trailing empty line at the bottom.
So: make sure the last line of the file actually contains text.
First of all, I did spend quite some time on research, and I know there are many related questions, though I can't find the right answer on this question.
I'm creating a SSIS package, which does the following:
1. Download and store CSV file locally, using HTTP connection.
And 2. Read in CSV file and store on SQL Server.
Due to the structure of my flat file, the flat file connection keeps giving me errors, both in SSIS as in the SQL Import Wizard.
The structure of the file is:
"name of file"
"columnA","columnB"
"valueA1","valueB1"
"valueA2","valueB2"
Hence the row denominator is end of line {CR}{LF} and the column denominator is a comma{,}, with text qualifier ".
I want to import only the values, not the name of the file or the column names.
I played around with the settings and got the right preview with the following settings (see image below)
- Header rows to skip: 0
- Column names in the first data row: no
- 2 self-configured columns (string with columnWidth = 255)
- Data rows to skip: 2
When I run the SSIS Package or SQL Import Wizard I get the following error:
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED. The
PrimeOutput method on Flat File Source returned error code 0xC0202091.
The component returned a failure code when the pipeline engine called
PrimeOutput(). The meaning of the failure code is defined by the
component, but the error is fatal and the pipeline stopped executing.
There may be error messages posted before this with more information
about the failure.
I can't figure out what goes wrong and what I can do to make this import work.
If you want to skip the file name and the column names, you need to set Header Rows to skip to 2. You should also check whether the file actually uses line feeds (LF) instead of CR+LF. Checking the line breaks in a text editor isn't enough to detect the difference, as most editors display correctly files with both CR+LF or LF.
You can check the results of your settings by clicking on the "Preview" button in your flat file source. If the settings are correct, you'll see a grid with your data properly aligned. If not, you'll get an error, or the data will be wrong in some way, eg a very large number of columns, column names in the first data row etc
I am trying to write data from a .csv file to my postgreSQL database. The connection is fine, but when I run my job i get the following error:

My job is very simple:
tFileInputDelimiter -> PostgreSQL_Output
I think that the error means that the double quotes should be single quotes ("" -> ''), but how can i edit this in Talend?
Or is it another reason?
Can anyone help me on this one?
Thanks!
If you are using the customer.csv file from the repository then you have to change the properties of customer file by clicking through metadata->file delimited->customer in the repository pane.
You should be able to right click the customer file and then choose Edit file delimited. In the third screen, if the file extension is .csv then in Escape char settings you have to select CSV options. Typical escape sequences (as used by Excel and other programs) have escape char as "\"" and text enclosure is also "\"".
You should also check that encoding is set to UTF-8 in the file settings. You can then refresh your preview to view a sample of your file in a table format. If this matches your expectations of the data you should then be able to save the metadata entry and update this to your jobs.
If your file is not in the repository, then click on the component with your file and do all of the above CSV configuration steps in the basic settings of the component.
