오류 코드 19 인 Android sqlite 삽입 : 제약 조건이 적용되지 않았습니다.

Question

이 주제에 대한 다른 질문을 검토했지만 응답이 없거나 저에게 효과적입니다. 내 DB에 삽입하려고하면 'SQLiteConstraintException : 오류 코드 19 : 제약 조건 실패'오류가 발생합니다.

여기 내 데이터베이스입니다 :

    } 
} 

을 그리고 여기 내 WorkoutEdit 클래스

//Saves all the data to the database 
    private void saveState() { 
     String title = workoutState; 
     String squatLabel = squats.getText().toString(); 


     if (mRowId == null) { 
      long id = mDbHelper.createNote(title, squatLabel); 
      if (id > 0) { 
       mRowId = id; 
      } 
     } else { 
      mDbHelper.updateNote(mRowId, title); 
     } 
    } 

그리고 마지막으로, 내 로그 캣에서 삽입 방법입니다!

Answer 1

삽입하여 SQLite 데이터베이스의 어느 데이터베이스 제약 조건을 위반하는지 파악해야합니다. 내가 아는 가장 좋은 방법은 삽입하려는 데이터에 대한 각 제약 조건을 시각적으로 확인하는 것입니다. 내가 바보 같은 소리지만 어디이 SQL을 실행한다면 죄송합니다,

select sql from sqlite_master 
where type='table' and name='your_table_name';
