bcp: Error = [Microsoft][SQL Server Native Client 10.0]String data, right truncation

Question

I have recently encountered an error while working with bcp. Here is the error.

SQLState = 22001, NativeError = 0 Error = [Microsoft][SQL Server Native Client 10.0]String data, right truncation

I'm trying to unpack the data into a staging table which does not have any constraints and the datatypes are also fairly large when compared to the data. I have about 11 files from different tables being bcp'd and zipped out of which only one file when unpacking errors out. This is the command which I have been using succesfully. Very recently(when trying to make a copy of the current WH and settign up the process) I have been facing issues.

bcp.exe employee_details in employee_details.dat -n -E -S "servername" -U sa -P "Password"

I have tried changing the commands to -C -T -S which worked when I gave the format manually. This is a very big and important packet I need to load in to my WH.
I don't know if I see a format file here or not. Any help is needed.

Thanks

We also faced same issue while doing BCP and it turned out to be an issue with new line character in .dat file.

View the file in Notepad++ and click on "Show All Characters" to see the new line character.

BCP throws following error with -r "\r\n" option i.e. with below command

bcp dbo.Test in C:\Test.dat -c -t "|" -r "\r\n" -S "DBServerName" -T -E

" SQLState = 22001, NativeError = 0 Error = [Microsoft][SQL Server Native Client 10.0]String data, right truncation "

BCP treat all rows in file as a single row with -r "\n" or -r "\r" option i.e. with below command

bcp dbo.Test in C:\Test.dat -c -t "|" -r "\n" -S "DBServerName" -T -E

Issue was resolved when we used the Haxadecimal value (0x0a) for New Line character in BCP command

bcp dbo.Test in C:\Test.dat -c -t "|" -r "0x0a" -S "DBServerName" -T -E
