위와 같이 만들었는데요, 아래와 같은 오류가 나옵니다...어디가 문제인지 조언 좀 부탁드려요 ㅠ.ㅠ

$this->db->select('

Project.projectName,
Project.projectStartDate,
Project.projectEndDate,
Project.projectAllTerm,
ifnull(Member_2D.memberPosition, "") AS memberPosition_2D,

이 부분에 에러가 있군요.

1. SQL에서는 "(더불쿼테이션)을 쓰면 에러가 납니다. 
2. 내장 함수가 들어 있어 문제가 되는군요.

이 두문제를 해결하면 아래와 같이 됩니다.

$this->db->select("
Project.projectCode,
Project.projectState,
Project.projectName,
Project.projectStartDate,
Project.projectEndDate,
Project.projectAllTerm,
ifnull(Member_2D.memberPosition, '') AS memberPosition_2D,
ifnull(Member_2D.memberName, '') AS memberName_2D,
ifnull(Member_3D.memberPosition, '') AS memberPosition_3D,
ifnull(Member_3D.memberName, '') AS memberName_3D
", FALSE);
