I get the following SSIS error message when my source file has blank lines at the end of the file. I don't care about the blank lines as they don't affect the overall goal of pumping data from a text file to a database table. I'd like to ignore this message or, if its easier, configure SSIS to ignore blanks.
<DTS:Column DTS:ID="96" DTS:IdentificationString="Flat File Source.Outputs[Flat File Source Error Output].Columns[Flat File Source Error Output Column]"/>
I found a similar question below, but the solution isn't an SSIS one, its one that preprocesses the text files which would be my least favorite solution.
SSIS Import Multiple Files Ignore blank lines
If you want to exclude records with blank values you can use the Conditional Split. Add it between you source file and your destination.
The expression can be like below :
ISNULL(Col1) && ISNULL(Col2) && ISNULL(Col3) ...
Name the output as Remove Blank Lines. When connecting your Conditional Split to your destination, SSIS will ask you what output the split component that needs to be returned. In this case chose the Conditional Split Default Output to get the entire records without the blank values.
You can enable Data Viewer before and after the conditional split to see the filtered output.

I am trying to import some data from a .csv file in SSMS using the "Import Flat File" option. However, not all the data is being copied.
Both data types are set to nvarchar(50).
The lines containing just a single value after the semi-colon is imported. Lines with multiple values are imported as NULL. I've tried separating the values with forward slashes and commas. The result is still the same.
How can I get the values imported instead of these NULL values?
I tested on my local machine with your example and everything is ok.
Maybe there is an issue in your flat file, have you checked your file is coherent (appropriate < CR >< LF > for example) in Notepad++ ?
Also, during the import, Is the result you see in the "preview" window correct ?
I have a file dump which needs to be imported into SQL Server on a daily basis, which I have created a scheduled task to do this without any attendant. All CSV files are decimated by ',' and it's a Windows CR/LF file encoded with UTF-8.
To import data from these CSV files, I mainly use OpenRowset. It works well until I ran into a file in which there's a value of "S7". If the file contains the value of "S7" then that column will be recognized as datatype of numeric while doing the OpenRowset import and which will lead to a failure for other alphabetic characters to be imported, leaving only NULL values.
This is by far I had tried:
Using IMEX=1: openrowset('Microsoft.ACE.OLEDB.15.0','text;IMEX=1;HDR=Yes;
Using text driver: OpenRowset('MSDASQL','Driver=Microsoft Access Text Driver (*.txt, *.csv);
Using Bulk Insert with or without a format file.
The interesting part is that if I use Bulk Insert, it will give me a warning of unexpected end of file. To solve this, I have tried to use various row terminator indicators like '0x0a','\n', '\r\n' or not designated any, but they all failed. And finally I managed to import some of the records which using a row terminator of ',\n'. However the original file contains like 1000 records and only 100 will be imported, without any notice of errors or warnings.
Any tips or helps would be much appreciated.
Edit 1:
The file is ended with a newline character, from which I can tell from notepad++. I managed to import files which give me an error of unexpected end of file by removing the last record in those files. However even with this method, that I still can not import all records, only a partial of which can be imported.
I am trying to load data from an Excel .csv file to a flat file format to use as a datasource in a Data Services job data flow which then transfers the data to an SQL-Server (2012) database table.
I consistently lose 1 in 6 records.
I have tried various parameter values in the file format definition and settled on setting Adaptable file scheme to "Yes", file type "delimited", column delimeter "comma", row delimeter {windows new line}, Text delimeter ", language eng(English) and all else as defaults.
I have also set "write errors to file" to "yes" but it just creates an empty error file (I expected the 6,000 odd unloaded rows to be in here).
If we strip out three of the columns containing special characters (visible in XL) it loads a treat so I think these characters are the problem.
The thing is, we need the data in those columns and unfortunately, this .csv file is as good a data source as we are likely to get and it is always likely to contain special characters in these three columns so we need to be able to read it in if possible.
Should I try to specifically strip the columns in the Query source component of the dataflow? Am I missing a data-cleansing trick in the query or file format definition?
OK so didn't get the answer I was looking for but did get it to work by setting the "Row within Text String" parameter to "Row delimiter".
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
