Question

我得到一个例外“SQLiteException：无法提交 - 没有事务处于活动状态”。当我尝试在DataBase中更新我的表时，会发生此异常。我不知道为什么会发生这种异常。这个例外是什么意思。所以如果有人知道那么请告诉我如何解决这个例外。在代码中，当我替换更新查询以插入查询时，不会发生错误。我的更新查询就像

e.g

ContentValues cVal=new ContentValues();
cVal.put("search", 0);
int count=sqLiteDatabaseWrite.update("TableName", cVal, null,null);

或者尝试这个

sqLiteDatabaseWrite.execSQL("update TableName set search=0");

在这两种情况下都会发生错误。在这里我打印我的logcat。

谢谢
