造成的：android.database.sqlite.SQLiteException：無法升級只讀0版本的數據庫1

我正試圖創建一個SQLite數據庫時，下面的logcat的例外：造成的：android.database.sqlite.SQLiteException：無法升級只讀0版本的數據庫1

引起：android.database.sqlite.SQLiteException：無法升級只讀從0版本1

這裏數據庫是我的代碼：

import static android.provider.BaseColumns._ID; 
import static org.inetizen.university_timetable.Constants.DAY_OF_WEEK; 
import static org.inetizen.university_timetable.Constants.DURATION; 
import static org.inetizen.university_timetable.Constants.MODULE_CODE; 
import static org.inetizen.university_timetable.Constants.ROOM; 
import static org.inetizen.university_timetable.Constants.START_TIME; 
import static org.inetizen.university_timetable.Constants.TABLE_NAME; 
import static org.inetizen.university_timetable.Constants.TYPE_OF_SESSION; 
import android.content.Context; 
import android.database.sqlite.SQLiteDatabase; 
import android.database.sqlite.SQLiteOpenHelper; 

public class TimeTableData extends SQLiteOpenHelper { 
private static final String DATABASE_NAME = "timetable.db"; 
private static final int DATABASE_VERSION = 1; 

/** Create a helper object for the TimeTable database **/ 
public TimeTableData(Context ctx) { 
    super(ctx, DATABASE_NAME, null, DATABASE_VERSION); 
} 

@Override 
public void onCreate(SQLiteDatabase db) { 
    db.execSQL("CREATE TABLE " + TABLE_NAME + " (" +_ID 
      + " INTEGER PRIMARY KEY AUTOINCREMENT " + MODULE_CODE 
      + " TEXT NOT NULL " + DAY_OF_WEEK + " TEXT NOT NULL " 
      + START_TIME + " INTEGER NOT NULL " + DURATION 
      + " INTEGER NOT NULL " + TYPE_OF_SESSION + " TEXT NOT NULL " 
      + ROOM + " TEXT NOT NULL)"); 
} 

@Override 
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME); 
    onCreate(db); 
} 
}

這裏是我的logcat：

如何解決異常有什麼建議？

set：version = 2 private static final int DATABASE_VERSION = 2; – MAC

嗨，感謝您的快速回復，我得到同樣的錯誤，但不能從版本0升級到2 – dickturnip

PLZ嘗試版本3或4它會工作 – MAC

您使用的是不看是正確的SQL語法，你錯過了逗號。試試這個：

db.execSQL("CREATE TABLE " + TABLE_NAME + " (" +_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + MODULE_CODE + " TEXT NOT NULL, " + DAY_OF_WEEK + " TEXT NOT NULL, " + START_TIME + " INTEGER NOT NULL, " + DURATION + " INTEGER NOT NULL, " + TYPE_OF_SESSION + " TEXT NOT NULL, " + ROOM + " TEXT NOT NULL)");

+1接得好！！ – Barak

三江源這並獲得成功:) – dickturnip

你可以試試getWritableDatabase（）。可能這個鏈接將幫助你。

你沒有展示你db.open方法......我敢打賭你不打開數據庫爲可寫。它應該看起來像這樣：

public GroceryDB open() throws SQLException { 
    mDBHelper = new DBHelper(mCtx); 
    mDb = mDBHelper.getWritableDatabase(); 
    return this; 
}

不好意思啊我有這樣的 \t私人光標getClasses（字串[] args）{ \t \t SQLiteDatabase DB = timeTable.getWritableDatabase（）;遊標cursor = db.rawQuery（「SELECT * FROM timetable WHERE day_of_week =？ORDER BY」+ ORDER_BY，args）; \t \t startManagingCursor（cursor）; \t \t返回遊標; \t} – dickturnip

啊。非常簡單的解決方案。 – Barak
