Вызвано: android.database.sqlite.SQLiteException: невозможно обновить базу данных только для чтения с версии 0 до 1

Я получаю следующее исключение LogCat при попытке создать базу данных SQLite:

Вызвано: android.database.sqlite.SQLiteException: невозможно обновить базу данных только для чтения с версии 0 до 1

Вот мой код:

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);
}
}

Вот мой ЛогКэт:

Любые предложения о том, как разрешить исключение?

Привет, спасибо за быстрый ответ, я получаю ту же ошибку, но не могу обновить версию 0 до версии 2. - dickturnip 09.05.2012

comment

попробуйте версию 3 или 4, все будет работать - MAC 09.05.2012

comment

проверьте свой logcat, есть еще одна ошибка, которая приводит к сбою создания/обновления базы данных. Возможно, потому что вы не добавили , после определения каждого столбца в инструкции создания. - zapl 09.05.2012

Вот паста logcat - dickturnip 09.05.2012

Синтаксис SQL, который вы используете, выглядит неправильным, вам не хватает запятых. Попробуйте вот это:

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)");

вы можете попробовать getWritableDatabase(). может эта ссылка вам поможет.

Вы не показали свой метод db.open... Могу поспорить, что вы не открываете db как доступную для записи. Это должно выглядеть примерно так:

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

Ах, извините, у меня есть этот частный курсор getClasses (String [] args) { SQLiteDatabase db = timeTable.getWritableDatabase (); Курсор курсора = db.rawQuery(SELECT * FROM timetable WHERE day_of_week = ? ORDER BY + ORDER_BY, args); startManagingCursor(курсор); возврат курсора; } - dickturnip; 09.05.2012

Ах. Вот вам и простое решение. - Barak; 09.05.2012
