我像往常一样创建了一个数据库，但今天我收到了这个错误，我无法理解我的数据库有什么问题。
我试过用谷歌搜索，但这里没有答案我下面的代码用于创建数据库
error in sqlite : cannot open file at line 27701 of [8609a15dfa],
public static final String ProvinceTable = "Provinces";
public static final String COLUMN_PID = "PID";
public static final String COLUMN_PName = "ProvinceNames";
public void onCreate(SQLiteDatabase db )
{
try {
db.execSQL(" CREATE TABLE " + ProvinceTable + " (" + COLUMN_PID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + COLUMN_PName + " TEXT)" );
}
public void onUpgrade(SQLiteDatabase db, int oldVersion , int newVesion) {
Log.w(TAG, "Upgrading database from version " + oldVersion + "to"
+ newVesion + ", which will destroy all old data");
db.execSQL("DROP TABLE IF EXISTS " + Cities_TABLE);
onCreate(db);
}
}
活动中
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.insertstock);
DBAdapter db = new DBAdapter(this);
db.open();
Log.d("Adding", "Added");
long id = db.insertRecord("name", "surname","***", "address", "email", "number","province", "City", "payment", "delivery", "cardnumber", "username","password");
db.close();
}
}
我在 logcat 中遇到了这个很长的错误。请帮我。
