我在Anroid应用程序中升级DATABASE_VERSION后收到此错误消息。
这是我的SQLiteOpenHelper类

当我将DATABASE_VERSION从5升级到6（将新列添加到Sticker表中）时，它工作正常。但是，当版本增加到7（将另一列添加到同一个表 - Sticker表中）时，该错误开始更频繁地发生（对于某些设备而非所有设备）。
有时，我收到了这个错误。
Caused by: android.database.sqlite.SQLiteException: no such table: skin_group (code 1): , while compiling: select * from skin_group limit 0
（当我们通过此方法更改方法以检查列是否存在时会发生这种情况 ）
public boolean checkIfColumnExist(SQLiteDatabase db, String column) {
Cursor cursor = db.rawQuery("select * from " + SKIN_GROUP_TABLE + " limit 0", null);
if (cursor.getColumnIndex(column) == -1) {
return false;
}
return true;
}
有时，

我一直试图通过
强制进行升级 public void forceUpdateDatabase() {
openDatabase();
db.close();
}
protected synchronized void openDatabase() {
if (db == null || !db.isOpen()) {
db = dbHelper.getWritableDatabase();
}
}
我的数据库中有几个表，这些表扩展了这个AbstractBizLogic以从这些表中获取数据。
public abstract class AbstractBizLogic {
protected SQLiteDatabase db;
private SQLiteOpenHelper dbHelper;
protected AbstractBizLogic(SQLiteOpenHelper dbHelper) {
this.dbHelper = dbHelper;
}
public TransactionManager beginTransaction() {
openDatabase();
return new TransactionManager(db);
}
protected synchronized void openDatabase() {
if (db == null || !db.isOpen()) {
db = dbHelper.getWritableDatabase();
