Determine ROW that caused “unexpected end of file” error in BULK INSERT?

i am doing a bulk insert:

DECLARE @row_terminator CHAR;
SET @row_terminator = CHAR(10); -- or char(10)

DECLARE @stmt NVARCHAR(2000);
SET @stmt = '
  BULK INSERT accn_errors
   FROM ''F:FullUnzippedaccn_errors_201205080105.txt''
   WITH 
      (
        firstrow=2,
FIELDTERMINATOR = ''|''  ,
ROWS_PER_BATCH=10000
   ,ROWTERMINATOR='''+@row_terminator+'''
   )'
exec sp_executesql @stmt;

and am getting the following error:

Msg 4832, Level 16, State 1, Line 2
Bulk load: An unexpected end of file was encountered in the data file.
Msg 7399, Level 16, State 1, Line 2
The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error.
Msg 7330, Level 16, State 2, Line 2
Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".

is there a way to know on which ROW this error occurred?

i am able to import 10,000,000 rows without a problem and error occurs after that

Answer

To locate the troublesome row use the errorfile specifier.

BULK INSERT myData
FROM 'C:......myData.csv'
WITH (
FIELDTERMINATOR = ',',
ROWTERMINATOR = 'n',
ERRORFILE = 'C:......myRubbishData.log' 
);

myRubbishData.log will have the offending rows and a companion file myRubbishData.log.txt will give you row numbers and offsets into the file.

Companion file example:

Row 3 File Offset 152 ErrorFile Offset 0 - HRESULT 0x80004005
Row 5 File Offset 268 ErrorFile Offset 60 - HRESULT 0x80004005
Row 7 File Offset 384 ErrorFile Offset 120 - HRESULT 0x80004005
Row 10 File Offset 600 ErrorFile Offset 180 - HRESULT 0x80004005
Row 12 File Offset 827 ErrorFile Offset 301 - HRESULT 0x80004005
Row 13 File Offset 942 ErrorFile Offset 416 - HRESULT 0x80004005
