Why SQL Server imports badly my CSV file with bcp? - sql-server

Question

I'm using bcp to insert a CSV file in my SQL table, but i'm having weird results.
All the environment is on Linux, I create the CSV file with IFS=\n in Bash. BCP is running from Bash too like this:
bcp Table1 in "./file.csv" -S server_name -U login_id-P password -d databse_name -c -t"," -r"0x0A"
The file.csv is about 50k rows. BCP tells me he copied 25K rows. No warnings, no errors. I have tried on a smaller sample with only 2 rows and here is the result:
file.csv data:
A.csv, A, B
C.csv, C, D
My table Table1:
CREATE TABLE Table1 (
ID INT NOT NULL IDENTITY(1,1) PRIMARY KEY,
a VARCHAR(8),
b VARCHAR(8),
c VARCHAR(8)
FOREIGN KEY (a) REFERENCES Table2(a)
);
Table2 is a very basic table just like Table1
What I can see in Microsoft SQL Server Manager Studio when i do SELECT * FROM Table1
ID | a | b | c |
1 A BC C.csv E
I export with bcp like this:
bcp Table1 out"./file_export.csv" -S server_name -U login_id-P password -d databse_name -c -t"," -r"0x0A"
What I get in file_export.csv
1, A, B
C, C.csv, D, E
I've check on NotePad++ any strange End Of File, they are all EF (50k Rows) each values are separated by comas.
UPDATE:
Changing the options -t and -r does not change anything. So my CSV is well formatted. I think the issue the fact that I'm trying to import x columns in a tables of x+1 fields (The auto-incremented ID).
So i'm using the simplest command for bcp
bcp Table1 in "./file.csv" -S server_name -U login_id-P password -d databse_name -c
Here is what i get in my SELECT * FROM Table1;
ID a b c
1 A BC.csv C,D
Here is what I expected:
1,A.csv,A,B
2,C.csv,C,D
Why does my first field is "eaten" and replace by 1 (ID)? Which makes everything swift to the right.
