解決方法：SQLiteException：そのようなテーブルはありませんか？

Question

私はこのSQLiteExceptionを取得しています：そのようなテーブルはありません。
私のコードには何の不具合も見られません。私は、アプリをアンインストールし、再インストールするよりも、それは動作しませんでした清掃しようとしました。

コード：
DatabaseContainerAdapter.java：例外は唯一TABLE_NAME3です

    class DatabaseContainer extends SQLiteOpenHelper { 

     public static final String DATABASE_NAME = "expenseDatabase"; 
     public static final int DATABASE_VERSION = 7;

     public static final String DATE = "date"; 

     public static final String TABLE_NAME3 = "budgetTable"; 
     public static final String YEAR = "year"; 
     public static final String BUDGET = "budget"; 

     public static final String CREATE_TABLE1 = "CREATE TABLE " + TABLE_NAME1 + " (" + CATEGORY + " varchar (20) ," + MONTH + " varchar(150)," + AMOUNT + " integer (10)," + ICON + " varchar(50));";

     public DatabaseContainer(Context context) {

     } 


     @Override 
     public void onCreate(SQLiteDatabase sqLiteDatabase) { 
      try { 
       sqLiteDatabase.execSQL(CREATE_TABLE1);

       sqLiteDatabase.execSQL(DROP_TABLE2); 
       sqLiteDatabase.execSQL(DROP_TABLE3); 
      } catch (SQLException e) { 
      } 
      onCreate(sqLiteDatabase); 


     } 
    } 

} 

、他のテーブルはOKです。
コントロールがonCreateメソッド（デバッガでチェックしたもの）とonCreate（）メソッドの中で、すべてのテーブルのCreate Tableクエリを実行しているので、私はここで全く混乱しています。他のテーブルが作成されていますが、TABLE_NAME3のみ例外が発生しています。

私が上記のコード（DatabaseContainerAdapter.java）で使用している3つの方法です。

public Cursor showBudget(String[] coloumns, String[] month) { 
     Cursor cr = null; 
     SQLiteDatabase db = dc.getWritableDatabase(); 
     try { 
      Cursor cursor = db.query(DatabaseContainer.TABLE_NAME3, coloumns, DatabaseContainer.MONTH + "=?", month, null, null, null); 
      cr = cursor; 
     } catch (SQLException e) { 
      e.printStackTrace(); 
     } 
     return cr; 
    } 

    public long insertBudget(String budget, int month) { 
     SQLiteDatabase db = dc.getWritableDatabase(); 
     ContentValues cv = new ContentValues(); 
     cv.put(DatabaseContainer.MONTH, month); 
     cv.put(DatabaseContainer.BUDGET, budget); 

//  cv.put(DatabaseContainer.ID, System.currentTimeMillis()); 
     long id = db.insert(DatabaseContainer.TABLE_NAME3, null, cv); 
     return id; 
    } 

    public long updateBudget(String budget, String[] month) { 
     SQLiteDatabase db = dc.getWritableDatabase(); 
     ContentValues cv = new ContentValues(); 
     cv.put(DatabaseContainer.BUDGET, budget); 
     long id = db.update(DatabaseContainer.TABLE_NAME3, cv, DatabaseContainer.MONTH + "=?", month); 
     return id; 
    } 

私はこれらの事を試してみました：

• クリーニングし、プロジェクトを再構築します。
• データベースバージョンの変更。
• アプリケーションをアンインストールしてから、再インストールしてください。
• キャッシュとアプリのデータをクリアしています。

何も私のために働いていません。

Answer 1

私はCREATE_TABLE3クエリに閉じ括弧を追加するのを忘れていると思います。

public static final String CREATE_TABLE3 = "CREATE TABLE " + TABLE_NAME3 
              + " (" + MONTH + " varchar (20) ," 
              + YEAR + " varchar (20) ," + BUDGET 
              + " integer(10)) ;"; 

Answer 2

閉じる括弧。 '）'がステートメントの最後にありません

Answer 3

まずあなたがSQLiteOpenHelperクラスを拡張し、onCreate()方法で表を作成します。それはこのようにする必要があります。

Plsのコード下のチェック -

import android.content.ContentValues; 
import android.content.Context; 
import android.database.Cursor; 
import android.database.sqlite.SQLiteDatabase; 
import android.database.sqlite.SQLiteOpenHelper; 


import java.util.ArrayList; 

/** 
* 
*/ 
public class DatabaseController extends SQLiteOpenHelper { 
    // Database Version 
    private static final int DATABASE_VERSION = 1; 

    // Database Name 
    private static final String DATABASE_NAME = "meeting_finder_db"; 


    // table name 
    private static final String TABLE_APP_INFO = "tbl_app_info"; 



    // TABLE_APP_INFO Columns names 
    private static final String KEY_APP_ID = "app_id"; 
    private static final String KEY_APP_NAME = "app_name"; 
    private static final String KEY_APP_IMAGE = "app_image"; 
    private static final String KEY_APP_STATUS = "app_status"; 
    private static final String KEY_APP_ORDER = "app_order"; 
    private static final String KEY_APP_SOCIAL_URL = "app_social_url"; 
    private static final String KEY_CREATED_AT = "createdAt"; 
    private static final String KEY_UPDATED_AT = "updatedAt"; 





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

    @Override 
    public void onCreate(SQLiteDatabase db) { 
     // Create APP table 
     String CREATE_APP_INFO = "CREATE TABLE " + TABLE_APP_INFO + "(" 
       + KEY_APP_ID + " INTEGER PRIMARY KEY," + KEY_APP_NAME + " TEXT," 
       + KEY_APP_IMAGE + " TEXT," + KEY_APP_STATUS + " TEXT," + KEY_APP_ORDER + " TEXT," 
       + KEY_APP_SOCIAL_URL + " TEXT," + KEY_CREATED_AT + " TEXT," + KEY_UPDATED_AT + " TEXT" + ");"; 



     db.execSQL(CREATE_APP_INFO); 


    } 

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

    }
