SQLite的错误语法错误

在我的情况，我想在数据库添加一些数据，但它一直告诉SQLite的错误语法错误

09-28 17:30:42.955: E/SQLiteLog(8370): (1) near "TABLEbook": syntax error

，但我找不到任何错误的即时通讯做。请帮忙... !!

这是我ActivityMain类

public class MainActivity extends ActionBarActivity implements OnClickListener { 
Button save; 
EditText name,category,auther,qnt; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main);     
    save=(Button)findViewById(R.id.btn_add); 
    name=(EditText)findViewById(R.id.et_name); 
    category=(EditText)findViewById(R.id.et_cat); 
    auther=(EditText)findViewById(R.id.et_auth); 
    qnt=(EditText)findViewById(R.id.et_qn); 
    save.setOnClickListener(this); 
} 
@Override 
public void onClick(View arg0) { 

    DatabaseHelper db = new DatabaseHelper(this); 

     String _name= name.getText().toString(); 
     String _cat= category.getText().toString(); 
     String _auth= auther.getText().toString(); 
     String _qnt=qnt.getText().toString(); 

     Log.d("Insert:","Inserting..."); 
     db.addAllDatabase(new Book(_name,_cat,_auth,_qnt)); 

} 
}

这是我的书类

public class Book { 

int _id; 
String _name; 
String _cat; 
String _auth; 
String _qunt; 

public Book(){} 

public Book(int id,String name,String cat, String auth, String qunt){ 
    this._id = id; 
    this._name = name; 
    this._cat = cat; 
    this._auth = auth; 
    this._qunt = qunt; 
} 
public Book(String name,String cat, String auth, String qunt){ 
    this._name = name; 
    this._cat = cat; 
    this._auth = auth; 
    this._qunt = qunt; 
} 

public int getID() { 
    return _id; 
} 

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

public String getName() { 
    return _name; 
} 

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

public String getCat() { 
    return _cat; 
} 

public void setCat(String cat) { 
    this._cat = cat; 
} 

public String getAuth() { 
    return _auth; 
} 

public void setAuth(String auth) { 
    this._auth = auth; 
} 

public String getQunt() { 
    return _qunt; 
} 

public void setQunt(String qunt) { 
    this._qunt = qunt; 
} 

}

这是我DAtabaseHelper类

public class DatabaseHelper extends SQLiteOpenHelper { 
//constant variables 
private static final int DATABASE_VERSION = 8; 
private static final String DATABASE_NAME = "bookManager"; 
private static final String TABLE_BOOK = "book"; 

private static final String KEY_ID="id"; 
private static final String KEY_NAME= "name"; 
private static final String KEY_CATEGORY = "category"; 
private static final String KEY_AUTHER = "auther"; 
private static final String KEY_QUNTITY = "quntity"; 

public DatabaseHelper(Context context){ 
    super(context,DATABASE_NAME,null,DATABASE_VERSION); 
} 

@Override 
public void onCreate(SQLiteDatabase db) { 
    String CREATE_NEW_TABLE = "CREATE TABLE"+ TABLE_BOOK +"(" 
           + KEY_ID +"INTEGER PRIMARY KEY ,"+KEY_NAME+"TEXT ," 
           + KEY_CATEGORY + "TEXT," + KEY_AUTHER + "TEXT," + KEY_QUNTITY + "TEXT"+")"; 

    db.execSQL(CREATE_NEW_TABLE); 
} 

@Override 
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 

    db.execSQL("DROP TABLE IF EXITS"+TABLE_BOOK); 
    onCreate(db); 

} 

//add 
public void addAllDatabase(Book book){ 
    SQLiteDatabase db = this.getWritableDatabase(); 

    ContentValues value =new ContentValues(); 
    value.put(KEY_NAME,book.getName()); 
    value.put(KEY_CATEGORY,book.getCat()); 
    value.put(KEY_AUTHER,book.getAuth()); 
    value.put(KEY_QUNTITY,book.getQunt()); 

    db.insert(TABLE_BOOK, null, value); 

    db.close();  
} 

//read single 

public Book getSingleBook(int id){ 

    SQLiteDatabase db = this.getReadableDatabase(); 
    Cursor cursor = db.query(TABLE_BOOK,new String[]{KEY_NAME,KEY_CATEGORY,KEY_AUTHER,KEY_QUNTITY 
      },KEY_ID+"=?",new String[]{String.valueOf(KEY_ID)},null,null,null,null); 
    if(cursor != null){ 
     cursor.moveToFirst(); 
    } 

    Book book=new Book(Integer.parseInt(cursor.getString(0)),cursor.getString(1),cursor.getString(2) 
      ,cursor.getString(3),cursor.getString(4)); 

    return book;   
}

如果你看看引用的sql logcat比它应该很明显，你的生物查询中缺少很多空格：'CREATE TABLEbook（idINTEGER PRIMARY KEY，nameTEXT，categoryTEXT，autherTEXT，quntityTEXT）' – 2014-09-28 18:14:03

@ xaver-kapeller谢谢你的帮助:) – kosala 2014-09-28 18:27:55

您忘记了多个空格。您需要在连接空间上避免使用名称进行连接的SQL。例如。这里的onCreate：

String CREATE_NEW_TABLE = "CREATE TABLE "+ TABLE_BOOK +" (" 
          + KEY_ID +" INTEGER PRIMARY KEY, "+KEY_NAME+" TEXT, " 
          + KEY_CATEGORY + " TEXT, " + KEY_AUTHER + " TEXT, " + KEY_QUNTITY + " TEXT)";

在onUpgrade

你应该把它固定在这个位置：

db.execSQL("DROP TABLE IF EXISTS "+TABLE_BOOK);

如果我们把它在你的代码生成此SQL中的最后一个例子：

DROP TABLE IF EXITSbook

但它应该是：

DROP TABLE IF EXISTS book
