SSIS Randomly Empties Out Column Data While Using Flat File Source
Jan 12, 2007
I'm having a problem using the Flat File Source while using the underlying .Net classes to execute SSIS Packages. The issue is that for some reason when I load a flat file it Empty's out columns randomly. Its happening in the Flat File Source Task. By random I mean that most of the times all the data gets loaded but sometimes it doesnt and it empty's out column data. Interestingly enough this is random and even the emptying out of columns isnt a complete empty, its more like a 90% emtpying. Now you'll ask that is the file different everytime and the answer is NO. Its the same file everytime. If I run the same file everytime for 10 times it would empty out various columns maybe 1 of those times. This doesnt seem to be a problem while working with dtexec or the Package Executor utility. Need Help!!
Hi everyone, I am using SSIS, and I got the folowing error, I am loading several CSV files in a OLE DB, Becasuse the file is finishing and the tak dont realize of the anormal termination, making an overflow. So basically what i want is to control the anormal ending of the csv file. please can anyone help me ???
I am getting the following error after replacing the '""' with '|'. The replacng is done becasue some text sting contains "" wherein the DFT was throwing an error as " The column delimiter could not foun".
[Flat File Source [8885]] Error: The column data for column "CountryId" overflowed the disk I/O buffer. [Flat File Source [8885]] Error: An error occurred while skipping data rows.

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.

I am trying to impliment a SSIS package where data source is a Flat file(.csv) file and destination is a sql server database.
The problem is my data source a flat file which consists of thousands of rows which are manually entered, so there is always a chance that in some rows they may miss a column value while entering data which results in an error.
Example: My flat file has headers like Sln, Name, Age, Designation. While entering data they may miss age and type it as 1,aaa,Consultant,,
Using SSIS package i want to track all row number in the flat file where data is entered wrongly so that i can correct only that row instead of checking all rows each time when my SSIS package throughs an error. I want to get all the row numbers in a sql server database which are wrongly entered.
Each day I receive a file with a different name. For example, the name is filename_mmddyyyy.txt where filename_ stays constant and mmddyyyy is the date of the file. The file is always in the same format.
I want to build an SSIS where I pass it this file name. I can write a script to generate the correct file name. How do I build the SSIS so it can accept the input parameter and find the correct file to process?
I am working to archive some old data from a data warehouse using SQL server and SSIS. The data will be read and denormalized, then shipped out to a delimited text file.
The rowcount of the incoming data is significant, call it 10M+ rows per unit of work (one text file).
There are development advantages of using a stored proc for the data source - mainly ease of changing the denormalization logic as required. Wondering if there are performance advantages of an embeded query for the data source instead?
It was mentioned by one developer that when using a stored procedure, the output stream from the proc and subsequent SSIS steps cannot start until the full procedure processing is complete; i.e. the proc churns out its' result set in one big chunk.
He hinted that an embedded query does not have this same effect, but I am not sure that is accurate.
I have a simple SSIS package -> It reads a local text file which has 10 rows of data ( id, name, telephone # ) and puts it into a table.
It uses the "SSIS Flat File source" to read and a "SQL Command" to insert into the table. I can see that it reads line by line and puts each line into one row in my table.
Now, my production data is over 5 GiG of mainframe data and it seems their data is arranged in some hierarchical form.. so the position or arrangement of data in that file is important.
I pulled the data using my package and as far as I can see , my SSIS package pulled one line at a time ( from the flat file) and pushed it into my table. For each row, I also created an identity column in my table to be able to identify the positional arrangement of the hierarchical data and then use relational mappings to suit our business needs.
In all of this, my assumption is -
"SSIS reads one line at a time, inserts to my table and goes down to the next line .
It does NOT read a snapshot of rows from the flat file so as to write them into the table using internal ordering methods based on that particular snapshot "
I am trying to create a program that transfers tables to flat files. At this point in time, I have suceeded in created one that creates delimited files.
However, I am now trying to create fixed-width files as you can do with the SSIS designer, but programatically.
Is there a way to programatically determine the width of a column from the source table? I can not seem to find any kind of function or member that stores this information or allows me to retrieve it.
I know what I need to change in order to set a width for a column, but I just don't know how to find the width without just asking the user to provide one.
What is the best way to deal with a flat file source when you need to add a new column? This happens constantly in our Data Warehouse, another field gets added to one of the files to be imported, as users want more data items. When I originally set the file up in Connection Managers, I used Suggest File Types, and then many adjustments made to data types and lengths on the Advanced Tab because Suggest File Types goofs a lot even if you say to use 1000 rows. I have been using the Advanced Tab revisions to minimize the Derived Column entries. The file is importing nightly. Now I have new fields added to this file, and when I open the Connection Manager for the file, it does not recognize the new columns in the file unless I click Reset Fields. If I click Reset Fields, it wipes out all the Advanced Tab revisions! If I don't click Reset Fields, it doesn't seem to recognize that the new fields are in the file?
Is it a waste of time to make Advanced Tab type and length changes? Is it a better strategy to just use Suggest Types, and not change anything, and take whatever you get and set up more Derived Column entries? How did the designers intend for file changes to be handled?
Or is there an easy way to add new fields to this import that I am overlooking? I am finding it MUCH more laborious to set up or to modify a file load in SSIS than in DTS. In DTS, I just Edit the transformation, and add the field to the Source and Destination lists, and I'm good to go. My boss isn't understanding why a "better" version is taking so much more work!
I have a package that reads data from a CSV file, transforms it and finally loads it in a destination DB table.
My current problem lies in the parsing of the input flat file. I shall illustrate it using a small example.
Source File: P;Product-1;Short Description for product 1 P;Product-2;Short Description for product 2
Problem: I configured the flat file connection manager to use semicolon as the column separator. But then I have received some sample flat files where I found that the semicolon might be sometimes used as content of a column data.
Possible Solutions: I have thought about 3 different solution and I would like to get your feedback and recommendations about them.
Alternative 1: Use a complex column delimiter, which wouldn't be used in the data.
Example: P#~#Product-1#~#Short Description for product 1 P#~#Product-2#~#Short Description for product 2
Question 1: - Is it possible to define such a customized column delimiter for the Flat File Connection Manager? - If yes, how can I do this?
Alternative 2: Use double quotes around the data, which the Flat File Source Adapter must somehow recognize and trim before pushing the data down the Data Flow.
Example: "P";"Product-1";"Short Description for product 1" "P";"Product-2";"Short Description for product 2"
Question 2: - Is it possible to configure the Flat File Source Adapter to work as described? - If yes, how can I do this?
Alternative 3: Use a Script Component and write the needed code for parsing the Flat File.
Question 3: - Do you have further suggestions/ideas for solving this parsing problem?
I have a flat file that is row delimited by x00 x0D x0A. Any ideas on how to specify the row delimiter in the Columns section of the Flat File Connection Manager?
My task is to write an SSIS package that picks up just one file from a directory and loads it into a database table. The filename is defined as being "ABC*.txt". So I must pick up only one file that matches that wildcard.
I can see two ways of doing this, but I can't get either to work:- 1. Use a Flat File Source connection and put the wildcard in the ConnectionString. i.e. ConnectionString = "C:\mydirABC*.txt" But SSIS doesn't seem to support that. 2. Use a Foreach Loop Container with a Foreach File Enumerator, and configure the enumerator as:- Folder = c:mydir Files = ABC*.txt This works well, but loops round for as many files match the wildcard. Is there any way of forcing it to drop out after the first time round the loop?
I'M NEW OF SQL SERVER BUT I'VE ALREADY GOT A LOT OF GOOD ADVICES BY YOU
I'M NOT IN ABLE TO RUN BY SQL SERVER AGENT AN SSIS PACKAGE:
THE PACKAGE IS MADE AS BELOW:
DATA SOURCE: FLAT FILE; OLE DB DESTINATION: SQL SERVER DBO.TABLE
I HAVE SEVERAL KIND OF DATA FLOWS SCHEDULED TO RUN DAILY, AND ALL OF THEM RUNNING CORRECTLY. THE ONLY ONE I'M ACTUALLY NOT IN ABLE TO MAKE RUN BY JOB IS THIS ONE. (BY VISUAL STUDIO RUNS FINE )
I'M GETTING BACK THE FOLLOWING ERROR: Description: SSIS Error Code DTS_E_PRODUCTLEVELTOLOW. The product level is insufficient for component "Flat File Source 1 1" (32)
I'VE GOT A LOOK ON WEB, AND SEEN THAT THIS ERROR IS NOTICED WHEN SSIS IS NOT INSTALLED ON THE CLIENT MACHINE, BUT THIS IS NOT MY CASE SSIS IS FULL INSTALLED AND RUNNING.
I'VE ALSO TRIED TO RUN THE PACKAGE DIRECTLY FROM THE SERVER MACHINE...IT DOESN'T RUN EVEN LIKE THAT
I'VE DISCOVERED THAT SOME SSIS FEATURES IS NOT AVAILABLE WIT SQL SERVER STANDARD EDITION ( THIS IS MY LICENSE ) DO YOU HAPPEN TO KNOW WHETHER THIS IS THE CASE OR NOT?
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):
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):
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:
My task is to read the filename from a database table and transfer the flat file data in to a table. In SSIS,I am able to fetch the file name using a Data Reader Source; but how to pass this fileName parameter to Flat File Source ?
In DTS I have used ActiveX script to pass filename variable as flatfilecon.Source. Any help ?
I have this SSIS data flow ( Flat file to sql server) that I want to add a step to redirect any "bad" data instead of fail out.
I had the red arrow hocked up to a sql new table to dump the bad data, but the flow still failed.
Here is the first error, and I knew what was wrong. A description field in that line has pipe(|) character in it, which also happen to be the column delimiter in this case.
[Flat File Source [1]] Error: Data conversion failed. The data conversion for column "Column 22" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
I knew if I fixed the data, every thing will be fine, but I just want to use this redirect feature of SSIS. Is there a place where I can turn off validation, or do something to make it work?
I am attempting to pull in data from a flat file data source that contains dates in the following format "01012007 10:22" which translates to Month Day Year and Military Time. I want to turn this into a DateTime format so that I can insert it into the proper column. I have a SQL statement which will do this (see bellow), but I can't figgure out how to run the statement on the data before it reaches its destination.
my package has a flat file source that should be extracting data from a text file passing the data to the next component in the data flow. the package validates fine, but the data isn't flowing. however, i see the data in the source component. i added a data viewer between the source and the next component to see if any data flowed and saw no data. can someone suggest how i should go about trying to debug this? thanks.
I was getting the product error associated with the full version of SSIS not installed so I ran the installation again and selected the Integration Services check box.
Now when attempting to import data into a database, the drop down list doesn't have a flat file option.
Hi All, In one of my SSIS Interface I have to Merge data from a Oledb source and a Flat file source.But after I read from the flat file I have do a basic validation of the file for the length of header,detail and trailer records and then process further.The above Validation I am doing within Script Component.If the validation fails the flow should pass out of the DataFlowTask without Initailsing the Oledb source.
But the problem is i am not able to connect anything to the Oledb source,i.e Oledb source is not taking any incoming Pointers. Earlier I had done the same Validation in Control Flow Task,but then the interface was reading the same file twice,once in the Control Flow Task and then again in the DataFlowTask.Which i should avoid now.
I hope many of you could have come across such a problem. Any help on this will be appreciated.
I'm getting a very strange potential loss of data error on my flat file source in the data flow. The flat file is fixed width and the column in question is defined as numeric [DT_NUMERIC]. The transform runs great if this column IS NOT A ZERO. As soon as a zero value is found, I get the error. It errors on the flat file source, so I haven't been able to use a data viewer to see what's going on.
I m using SSIS and i am transfering the data from Flat File Source to the OLE DB destination File. The source file contain some corrupt data which i am transfering to the other Flat file destination file.
Debugging is succesful but i am not getting any error output in the Flat file destination file.
i had done exactly which is written in the msdn tutorial of SSIS.
Plz tell me why i am not getting the error output in the destination flat file?
hi - I am totally new to SSIS etc and SQL 2005. I have a dts task to recreate in SSIS. I have done most of them and muddled my way through, but this basic problem has got me stuck. When mapping columns from my file to my ole db output table, I want to map one input column onto two output columns, but it will only seem to let me select one destination column for each input? I have tried shift/alt/ctrl etc to try to get it to map to both columns but it wont have it. How do I do it?
Also, somehow my Dataflow Sources tab has gone from the toolbox, and I can't seem to get it back any way - I switched on everything I could see and all components etc, but it is not in there as an option. How do I get it back in the toolbox?
All, I'm having an issue with the Flat File Data Flow Source returning only a limited set of the rows that are in the flat file. Basically, I connect to the flat file fine, it goes to retrieve the data (tab delimited file) and only returns 190 of 392 rows. Is there a limitation on the # of rows this data flow source can retrieve or something? I've look all through the settings and properties of the task as well as the connection manager and nothing is obvious as to what is causing this. Hopefully someone ou tthere has run into this before and can help me retrieve all rows. Thanks in advance!
I want to use Import/Export wizard. In "Choose a data Source" screen, I can't see "Flat File" in "Data Source" List. Please help me how to insatall (or find) flat file connection manager
I am writing a package that will process delimited flat files that will come in one of a few different versions. Within each flat file, the number of delimited columns will be the same, but each version of the file has a different number of columns. I have tried configuring the flat file data source to expect the version with the largest number of columns, but it will then throw away rows that have less than this number of columns (warning: There is a partial row at the end of the file).
Is it possible to use a single flat file data source that will work with all of the different width files?
How do i use the foreach loop container and pass each file found according to a specified pattern to a Flat File Source in a Data Flow Task Object so i can operate on each file found in the foreach loop object instead of having to specify a static file name
