그런 표 (코드 1)

Question

임라는 오류 메시지가 점점 :

android.database.sqlite.SQLiteException : 그런 표는 DATABASE_TABLE 곳 KEY_ROWID에서 KEY_HOURS을 선택 다른 활동이 upDateUser (문자열 돈)을 호출 할 때 = 0

이 문제가 발생합니다

나는 제거하고 그것이 그 졸 그러나이 같은 다른 유사한 질문에 언급 된 것처럼 응용 프로그램을 다시 설치 시도

ution이 나 자신을 위해 작동하지 않습니다.

내 데이터베이스 클래스 코드 : KEY_CREDITS, DATABASE_TABLE 및 리터럴 인용 된 문자열 밖으로 KEY_ROWID 그 상수 변수의 값이 대신 사용되도록 당신이 끌어한다 여기에서

Answer 1

:

String selectQuery = "SELECT KEY_CREDITS from DATABASE_TABLE where 
           KEY_ROWID = " + 0; 

로 변경

Answer 2

사용하려고 시도하십시오 :

String selectQuery = "SELECT " + KEY_CREDITS + " from " + DATABASE_TABLE+ " where " + 
            KEY_ROWID + " = 0";
