저 다른질문하나만드려도될까요?

게시판 리스트에 제목,내용 검색하는거를 다른필드로 바꿔야해서 바꿨떠니

오류가 나네요

select distinct wr_parent from g4_write_test where ((INSTR(, '변호사')) ) and (wr_num between '-3' and '9997')

1064 : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' '변호사')) ) and (wr_num between '-3' and '9997')' at line 1

error file : /bbs/board.php

왜이런건지 알수있을까요?

아니면 검색다른필드넣는법이라도 있나요?
