问题 I am generating some data that I want to chart using QChart & friends. This is my first time using QChart , and so basically what I did was copy the QLineSeries Example and modify it to my needs. My current code looks like this: quint64 last=0; quint64 *lastp=&last; MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) , ui(new Ui::MainWindow) , series( nullptr ) { ui->setupUi(this); QChart *chart = new QChart(); series=new QLineSeries(chart); chart->legend()->hide(); chart->addSeries

问题 With repeatable read isolation level, it is still possible to lose updates (second lost updates problem). E.g. in the scenario with isolation level set to RR: 1) transaction t1 reads data from row r1, 2) transaction t2 reads same data from row r1, 3) t1 modifies the data read in #1 and commits data to r1 4) t2 modifies the data read in #2 and commits data to r1. t1's update is lost I tried this with Hibernate (isolation level set to RR) and saw the behavior as mentioned above. Why then is it

问题 I'm seeing extremely slow installs of system image updates on my Android Studio 3.0 running on a macOS High Sierra system. What do I mean by "extremely slow"? Every system image update takes the better part of an hour. To my disgust, the latest set of updates (shown here from the component installer log) took over eight hours: To install: - Google APIs Intel x86 Atom System Image (system-images;android-24;google_apis;x86) - Google APIs Intel x86 Atom_64 System Image (system-images;android-25

问题 I am trying to write an Update query with LEFT JOIN in BigQuery but I am not sure how to write it. update Table1 set ColumnTest = ifnull(b.value, 'no run') From left join (select distinct ID,value FROM Table2 where value = 10) B -- where Table1.ID= Table2.ID I have 2 tables Table1 and Table2 I want to update Table1.ColumnTest with Table2.Value where Table1.ID= Table2.ID and if Table1 <> Table2 then update Table1.ColumnTest with 'no run' Thanks!! New Try UPDATE Table1 SET LP = IFNULL(t2.value,

问题 I am going to use WUA API and begin execution of an asynchronous search for updates in this way: CComPtr<SearchCallbackImpl> iscc_; <<-- Note you need to CreateInstance CComPtr<ISearchJob> pUpJob_; pUpJob_ = NULL; pUpSearcher_->BeginSearch( CComVariant(criteria.c_str()).bstrVal, iscc_, CComVariant(L"Scanning"), &pUpJob_); When I need to stop my program, but ISearchJob has not completed yet, I use this code: if (pUpJob_) { CComVariant isStopped; pUpJob_->get_IsCompleted(&isStopped.boolVal); if
