from 'g3 게시판테이블'

)

insert into g4_board_file (
bo_table, wr_id, bf_no, bf_file, bf_source, bf_datetime
)
(
SELECT
'g4게시판의 bo_table', wr_id, '0', wr_file1, wr_file1_source, wr_datetime
from 'g3 게시판테이블'

)



insert into g4_board_file (
bo_table, wr_id, bf_no, bf_file, bf_source, bf_datetime
)
(
SELECT
'g4게시판의 bo_table', wr_id, '1', wr_file2, wr_file2_source, wr_datetime
from 'g3 게시판테이블'
)



3. bf_source 가 비어 있으면, 첨부파일 없으므로

delete from g4_board_file where bf_source = ''



4. data/file 폴더로 첨부된 파일들 복사하기



5. g4_board 에 bo_count_write 숫자 조정하기
