SQLite 데이터베이스 구문 오류로 인해 강제 종료

Question

SQLite 데이터베이스에 삽입하려고하지만 에뮬레이터에서 프로그램을 실행할 때마다 강제 종료됩니다. 내 데이터베이스 생성 내 구문 때문에 무언가가 있다고 생각하지만 트리플 체크하고 내 오류를 찾을 수 없습니다. 내가 생각할 수있는 유일한 다른 점은 SQlite 데이터베이스를 올바르게 실행하기 위해 매니페스트에 뭔가를 추가해야만하는 경우입니다.

다음은 내 도우미 클래스의 코드입니다.

public class dbhelper extends SQLiteOpenHelper { 

    public static final String DATABASE_NAME = "swimmers"; 
    public static final String TABLE_SWIMMERS = "sfd table"; 

    public static final String C_ID = "id"; 
    public static final String NAME = "name"; 
    public static final String TEAM = "team"; 
    public static final String NOTES = "notes"; 

    public static final int VERSION = 1; 

    public dbhelper(Context context) 
    { 
     super(context, DATABASE_NAME, null, VERSION); 
    } 

    @Override 
    public void onCreate (SQLiteDatabase db) 
    { 
     String createdb = "create table " + TABLE_SWIMMERS + "(" + C_ID + " integer primary key autoincrement, " + NAME + " text, " + TEAM + " text, " + NOTES + " text); "; 
     db.execSQL(createdb); 
    } 

    @Override 
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) 
    { 
     db.execSQL("drop table " + TABLE_SWIMMERS); 
     onCreate(db); 
    } 

    //add new entry 
    void addSwimmer(Swimmer swimmer){ 

     SQLiteDatabase db = this.getWritableDatabase(); 
     ContentValues values = new ContentValues(); 

     values.put(NAME, swimmer.getname()); 
     values.put(TEAM, swimmer.getteam()); 
     values.put(NOTES, swimmer.getnotes()); 

     db.insert(TABLE_SWIMMERS, null, values); 
     db.close(); 
    } 

    //Getting single swimmer 
    Swimmer getSwimmer(int id){ 
     SQLiteDatabase db = this.getReadableDatabase(); 

     Cursor cursor = db.query(TABLE_SWIMMERS, new String[] { C_ID, NAME, TEAM, NOTES}, C_ID + "=?", new String[] { String.valueOf(id) }, null, null, null, null); 
     if (cursor !=null) 
      cursor.moveToFirst(); 

     Swimmer swimmer = new Swimmer (Integer.parseInt(cursor.getString(0)), cursor.getString(1), cursor.getString(2), null); 
     return swimmer; 
    } 

    public int updateSwimmer(Swimmer swimmer){ 
     SQLiteDatabase db = this.getWritableDatabase(); 
     ContentValues values = new ContentValues(); 

     values.put(NAME, swimmer.getname()); 
     values.put(TEAM, swimmer.getteam()); 
     values.put(NOTES, swimmer.getnotes()); 

     return db.update(TABLE_SWIMMERS, values, C_ID + " = ?", new String[] { String.valueOf(swimmer.getID()) });   
    } 

    //delete single contact 
    public void deleteSwimmer(Swimmer swimmer){ 
     SQLiteDatabase db = this.getWritableDatabase(); 
     db.delete(TABLE_SWIMMERS, C_ID + " = ?", new String[] { String.valueOf(swimmer.getID()) });   
     db.close(); 
    } 

    //get contacts count 
    public int getSwimmersCount(){ 
     String countQuery = "SELECT * FROM " + TABLE_SWIMMERS; 
     SQLiteDatabase db = this.getReadableDatabase(); 
     Cursor cursor = db.rawQuery(countQuery, null); 
     cursor.close(); 
     return cursor.getCount(); 
    } 

} 

다음은 내가 만든 내 수영 클래스 내가 데이터베이스로 수영을 삽입하려합니다.

public class Swimmer { 

//private variables 
int _id; 
String _name; 
String _team; 
String _notes; 


public Swimmer(int id, String name, String team, String notes){ 
    this._id = id; 
    this._name = name; 
    this._team = team; 
    this._notes = notes; 
} 

public Swimmer(String name, String team, String notes){ 
    this._name = name; 
    this._team = team; 
    this._notes = notes; 
} 

public int getID(){ 
    return this._id; 
} 

public void setID(int id){ 
    this._id = id; 
} 

public String getname(){ 
    return this._name; 
} 

public void setname(String name){ 
    this._name = name; 
} 

public String getteam(){ 
    return this._team; 
} 

public void setteam(String team){ 
    this._team = team; 
} 

public String getnotes(){ 
    return this._notes; 
} 

public void setnotes(String notes){ 
    this._notes = notes; 
} 
} 

다음은 데이터베이스에 열고 삽입하는 코드입니다.

다음은 수영을 시도 할 때의 실수입니다.

모든 도움을 주시면 감사하겠습니다!

Answer 1

테이블은 SQLite 용 키워드입니다. 변수 TABLE_SWIMMERS를 TABLE_SWIMMERS = "sfd table";에서 TABLE_SWIMMERS = "sfd";으로 변경하면 제대로 작동합니다.
