SQL - read CSV file with unexpected EOF error - sql-server

Question

I need to read data from .csv file which contains many records, but in last row
there is string "the_end" and after that there is no LF sign.
Here is my csv file:
1,James,Smith,19750101
2,Meggie,Smith,19790122
3,Robert,Smith,20071101
4,Alex,Smith,20040202
the_end
Below my sql script which reads data into temporary table:
create table #Data
(
id int,
first_name varchar(50),
last_name varchar(50),
birthdate smalldatetime
)
bulk insert #Data
from 'C:\Users\Michał\Desktop\csvtest.csv'
with
(
FIELDTERMINATOR = ',',
ROWTERMINATOR = '\n'
)
select * from #Data
drop table #Data
Error is:
Msg 4832, Level 16, State 1, Line 13
Bulk load: An unexpected end of file was encountered in the data file.
Msg 7399, Level 16, State 1, Line 13
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 13
Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".
I want to read all data into my table without this last line label "the_end", that's obvious. How can i manage that? I cannot modify this file, because it's given from outside and I cannot do that.

Answer 1

Use the lastrow option
bulk insert #Data
from 'C:\Users\Michał\Desktop\csvtest.csv'
with
(
FIELDTERMINATOR = ','
, ROWTERMINATOR = '\n'
, lastrow = 4
)
dynamic sql example using a variable for lastline:
create table #Data (
id int
, first_name varchar(50)
, last_name varchar(50)
, birthdate smalldatetime
);
declare #lastline int = 4;
declare #sql nvarchar(max)= '
bulk insert #Data
from ''C:\Users\Michał\Desktop\csvtest.csv''
with (
FIELDTERMINATOR = '',''
, ROWTERMINATOR = ''\n''
, lastrow = '+convert(nvarchar(11),#lastline)+'
);';
exec sp_executesql #sql;
select * from #Data
drop table #Data

If the lastrow option doesn't work for you, manually delete the last row and try to re-run your BulkLoad process. If everything works fine, crate a VB.NET executable to open the file, strip out the last row, and re-save the file. can schedule the delete-last-row process and the BulkLoad process using the Windows Task Scheduler.
