Hello,
I have a flat file source with ragged right format. It has three columns.
My package fails when the last column has null values.
It says "The value could not be converted because of a potential loss of data".
So tried lot changing row delimiter and column delimiter but to no avail.
So any idea on this is well appreciated.
Thanks in advance.
The following error is encountered when importing a delimited flat file with date of fomat "dd.mm.yyyy"
Error: 0xC02020A1 at Data Flow Task, Source - DCDtest_xpt [1]: Data conversion failed. The data conversion for column "value date" returned status value 2 and status text "The value could not be converted because of a potential loss of data.".
This was when I manually built the package.
I get the same error when using the Import/Export wizard
I am even using the "suggest types" button and have tried sampling the default number of rows (?200) and also 2000.
The type it suggests is DT_DATE.
But reading the BOL, this would appear to be the wrong type:
http://msdn2.microsoft.com/en-us/library/ms141036.aspx (obviously the right hand doesn't know what the left hand is doing)
seems to indicate that
DT_DBTIMESTAMP
is the correct value
(I cannot believe that they have different datatypes in SSIS than in SQL. I can't believe for a minute this is for all the hundreds of thousands of Oracle users who obviously switched to SSIS when they saw what a high quality product it is.)
I tried other DT_... values but no dice.
Can anyone help?
I always thought that Classic ASP was the worst product I've ever worked with from the Microsoft stable, but I was wrong.
I am fed up of having to post on this board (no wonder it is so 'popular')
Talking to peers, reading books, googling nearly always enables me to figure out a problem with any application I have ever used, but SSIS breaks the mould in sheer crapness and the weirdnes and unfathomability of its cryptic errors,.
Rant over (for today)
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.
Please Help!?
Thanks,

I am using SQL Server 2005.
I am trying to import data from CSV files into an SQL Server table using the Import wizard. The text qualifier is double quotes ("), column delimeter is a comma (,), first row has column names. One of the field name is "id", which is a GUID, whose datatype in SQL Server is uniqueidentifier. It looks like this in the file:
..."data","data","dbf7edf8-0ca8-4e53-91e3-5901cdc1819a","data"...
As you can see, there are no enclosing curly braces for the guid value. The DTS chokes on this and throws this error:
The value could not be converted because of a potential loss of data
If I add curly braces like this {dbf7edf8-0ca8-4e53-91e3-5901cdc1819a}, it imports with no problem.
Is there way to import this type of data, because there is no way I can edit these files, and I would prefer not changing the datatype of the id field?
Or is this a limitation of SQL Server?
Thanks,Bullpit
I have a FoxPro dbf that includes From Milepost (f_mp) and To Milepost (t_mp) fields. These fields contain values between -1 and 9999.9999.
I don't have FoxPro installed, but when I attach the dbf to Access, I see the fields defined as datatype Double.
I have a SQL table that I'm trying to import the dbf data into. In that table the two fields are defined as datatype Real.
When I execute the task, it fails at the first milepost value with 4 digits to the left of the decimal point.
I read up on datatypes, then redefined the milepost fields as Floats, but nothing changed.
Any ideas or suggestions would be greatly appreciated.

I've searched the threads and didn't see anything which seemed to fit this specific issue....
I have a Data Flow task which reads from an OLE DB Source (SQL Server 2005), uses a Data Conversion transformation to convert some field values, and finally outputs the result to distinct tabs of an Excel workbook. The task is failing with the following error:
There was an error with input column "oBBCompanyName" (2162) on input "Excel Destination Input" (57). The column status returned was: "The value could not be converted because of a potential loss of data.".
Using the Advanced Editor for the Excel Destination component, I examined the datatype of oBBCompanyName (ID = 2162) in the Input Columns list of the "Excel Destination Input" (identified with ID = 57). The Data Type is defined as DT_WSTR with Length = 255. The ExternalMetaDataColumnID = 203.
Also in the Advanced Editor for the Excel Destination, I examined the datatype of BBCompanyName (ID = 203) in the Extranl Columns list of the Excel Destination Input. The Data Type is defined as "Unicode String [DT_WSTR] with Length = 255.
What could I be overlooking that might be the root cause of this issue? The same error is occurring for different Excel Destination tasks in the data flow.
Kind regards,

Hi,
I am getting the error below in my Flat File Source.
I've seen this error many times before, and have successfully resolved this problem in the past.
However, this time it's a little different. It's complaining about row 7 of myFile.csv, column 20. I have column 20 defined as a Numeric(18,6). It also maps to the Price field in the table, which is also a Numeric(18,6).
The problem is, on row 7 of myFile, column 20 is blank. That is, there's no data for row 7, column 20.
So, why should it care about this?? If it's blank, then how can you lose any data?? I have several other blank columns in this file, but they aren't throwing any errors. Just this one.
Thanks

Hi
I am having a bit of a difficult trying to understand this one. I had imported two tables around 2-300 rows each ran this in 64 bit scheduled it and it ran okay. I now introduced a 3rd table which if I change the true64bit to false it will run however if left true it keeps mentioning the output column of descr with a loss of data.
I did move it to 32bit and then ran the package it comes up as below. If I rememeber I can run this in 32bit mode which I'm sure will work hmm maybe!! but what I can't understand is why it works for two tables? is it something to do with the translation of the table or do I need alter the select statement?
Currently it is a select *

With my SSIS package, I want to import data from a flat file (TXT- delimited with ?) to a table in my database in sql server 2005. The problem is that I have a column of type datetime in my table. But as you know, the data in txt is string. First I created my package through importing data and using import/export wizard in management studio to my database and selecting flat file connection. There, I selected my txt file and column delimiter as ?, then suggested types for the columns. There it selects 8 byte signed integer type for the datetime column in my table. After these steps I create my package and execute it. But it does not put data in my table in the database. It gives the error of "The value could not be converted because of a potential loss of data" or "cast conversion failed" . I tried other types of date, timestamp, string but none of them was successful. What should I do to put data in my table from txts. Please can you help me urgently!!!
Thanks a lot
Hi,
I have a flat file that has a date column where the date fields look like 20070626, for example. No quotes.
The problem is that several of the date values are missing, and instead of the date value the field looks like this , ,
That is, there are several blank spaces where the date should be. The number of blank spaces between the commas doesn't appear to be a set number (and it could even be 8 blank spaces, I don't know, in which case I don't know if checking for the Len will produce the correct results, but that's another issue...)
So, similar to the numeric field blanks problem, I wrote a script to convert the field to null. This is the logic I used:
If Not Len(Row.TradeDate) = 8 Then
Row.TradeDate_IsNull = True
End If
The next step in my data flow after the script is a derived column where I convert TradeDate from 20070625 to 06/25/2007. So the exact error message I am receiving is this:
[OLE DB Destination [547]] Error: There was an error with input column "TradeDate - derived" (645) on input "OLE DB Destination Input" (560). The column status returned was: "The value could not be converted because of a potential loss of data.".
Do I need to add a conditional split after the script and BEFORE the derived column to redirect bad rows so they don't go to the derived column?
What am I doing wrong here?
Thanks

Hello
I have an odd problem that is driving me nutz. I have a very simple SSIS package that imports a 5 colum flatfile into a sql Server 2005 Table.
When I created this package with the wizzard, it will execute perfectly fine and processes all rows into the destination table.
But when I hit F5 to execute it manually it will fail before inserting a single row.
The error it generates is (Spalte 5 is a Datetime in the format DD.MM.YYYY) :
Error: 0xC02020A1 at Datenflusstask, Source - Daten_NC_1_txt [1]: Data conversion failed. The data conversion for column "Spalte 5" returned status value 2 and status text "The value could not be converted because of a potential loss of data.".

An error occurred on the specified object of the specified component.
Error: 0xC0202092 at Datenflusstask, Source - Daten_NC_1_txt [1]: An error occurred while processing file "C:WorkDaten_NC_1.txt" on data row 177.

Hi,
I am getting this error when my ssis package is running
Data Conversion failed due to Potential Loss of data
the input column is in string format and output is in sql server bigint
the error is occuring when there is an empty string in the input. what should i do to overcome this
It is an ID field and should i convert to bigint or should i leave it as char datatype is it i a good solution or is there a way to over come this.
Is there away to use wild card in the file name for the flat file data source?
Like //servername/directory/*.txt
Hi, all,
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?
Thanks!
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.
Can anyone help?
The code is:
Code Block
cast(convert(varchar(16),(substring( REPORT_RUN_DATE,1,2 ) + '/' + substring( REPORT_RUN_DATE,3,2 ) + '/' + substring( REPORT_RUN_DATE,5,10 )),1) as datetime) AS REPORT_RUN_DATE
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.

Hi,
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.
Any suggestions are sincerly apriciated.
Thanks in advance
Regards,
gcs.
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.
How do I import data from a txt, csv file?
Thanks

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.
cheers

View 1 Replies View RelatedEach 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.

Hi all,
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?
thanx
I have a CSV Flat File Source with a Decimal column - but DataPrecision property is grayed out - why?

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 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?
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!!

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'm importing a large csv file two different ways - one with Bulk Import Task and the other way with the Data Flow Task (flat file source -> OLE DB destination).
With the Bulk Import Task I'm putting all the csv rows in one column. With the Data Flow Task I'm mapping each csv value to it's own column in the SQL table.
I used two different flat file sources and got the following:
Flat file 1: Bulk Import Task = 12,649,499 rows; Data Flow Task = 4,215,817 rows
Flat file 2: Bulk Import Task = 3,403,254 rows; Data Flow Task = 1,134,359 rows
Anyone have any guess as to why this is happening?
I'm trying to build a DTSX package that FTP's an XML file to the local file system and then imports it into an existing table.
My "Data Flow" for the package starts with an XML Source component and then goes to Data Conversion component and then to an OLE DB Destination component.
It all executes with out error and seems to work fine, but when I look at the data in the table after I've run the package it seems to have inserted the appropriate number of rows from the XML file but all of the column values are NULL.
All of the data in the XML file is surrounded by <![CDATA[ ]]> and I discovered that if I remove the CDATA wrapper by hand then it inserts the data properly. The only problem is that I'm not in a position to have the data provider remove the CDATA tags and some of the data in the XML file needs the CDATA wrapper or else it will not validate.
Anyone know of anything I can do to get the CDATA to import properly?
