TSQL BULK INSERT with auto incremented key from .txt file - sql-server

Question

error im getting
This is to insert into an already created table:
CREATE TABLE SERIES(
SERIES_NAME VARCHAR(225) NOT NULL UNIQUE, --MADE VARCHAR(225) & UNIQUE FOR FK REFERENCE
ONGOING_SERIES BIT, --BOOL FOR T/F IF SERIES IS COMPLETED OR NOT
RUN_START DATE,
RUN_END DATE,
MAIN_CHARACTER VARCHAR(20),
PUBLISHER VARCHAR(12),
S_ID INT NOT NULL IDENTITY(1,1) PRIMARY KEY,
CONSTRAINT chk_DATES CHECK (RUN_START < RUN_END)
)
and the text file is organized as:
GREEN LANTERN,0,2005-07-01,2011-09-01,HAL JORDAN,DC
SPIDERMAN,0,2005-07-01,2011-09-01,PETER PARKER,MARVEL
I have already tried adding commas to the end of each line in .txt file
I have also tried adding ,' ' to the end of each line.
Any suggestions?

Answer 1

Indeed, the KEEPIDENTITY prevents the bulk insert from taken place. Removing the statement however won't resolve the problem.
Msg 4864, Level 16, State 1, Line 13
Bulk load data conversion error (type mismatch or invalid character for the specified codepage) for row 1, column 7 (S_ID).
The bulk insert expects to update all the columns. Another way of solving this issue is adding a format file for the text file, see MS Docs - Use a Format File to Bulk Import Data
You can create a format file for your text file with the following command.
bcp yourdatabase.dbo.series format nul -c -f D:\test.fmt -t, -T
Remove the last row, update the number of columns, and replace the last comma with the row terminator. The result will look like as shown below.
13.0
6
1 SQLCHAR 0 255 "," 1 SERIES_NAME SQL_Latin1_General_CP1_CI_AS
2 SQLCHAR 0 1 "," 2 ONGOING_SERIES ""
3 SQLCHAR 0 11 "," 3 RUN_START ""
4 SQLCHAR 0 11 "," 4 RUN_END ""
5 SQLCHAR 0 510 "," 5 MAIN_CHARACTER SQL_Latin1_General_CP1_CI_AS
6 SQLCHAR 0 510 "\r\n" 6 PUBLISHER SQL_Latin1_General_CP1_CI_AS

Answer 2

Remove KEEPIDENTIY from your BULK INSERT, since that specifies that you want to use the values in the source text file as your IDENTITY.
If this still fails, try adding a VIEW on the table that excludes the IDENTITY field, and INSERT into that instead, e.g.:
CREATE VIEW SeriesBulkInsertTarget
AS
SELECT Series_Name,
Ongoing_Series,
Run_Start,
Run_End,
Main_Character,
Publisher
FROM SERIES
