위의 샘플 데이터를 양식 없이 바로 입력했을 경우.. 데이터가 깨진다.

(Microsoft SQL Server management Studio에서는 제대로 입력됨.. 하지만 프로그램을 이용하면 다름과 같이 보인다.


BULK INSERT [데이터베이스이름].[db_owner].[bulksample]
FROM 'C:\SampleFolder\sample.csv'
WITH

    FIELDTERMINATOR=',',
    ROWTERMINATOR = '\n',

그래서 포맷을 이용하여 code 부분을 수정해야한다.

그후 C:\Samplefolder에 bcp.fmt 파일이 보인다.

이 파일을 sample.fmt로 복사한다.

메모장에서 열어보면 다음과 같다.

다음과 같이 명령어 입력..

 BULK INSERT [데이터베이스이름].[db_owner].[bulksample]

WITH (
    FORMATFILE = 'C:\SampleFolder\sample.fmt',
