Question

我有：

remoteDB();
QSqlQuery query("SELECT * FROM products");
int id = query.record().indexOf("id");
int aa = query.record().indexOf("license_type");
int bb = query.record().indexOf("free_trial_product_code");
int zz = query.record().indexOf("free_trial_license_number");
int xx = query.record().indexOf("free_trial_claimed_current_status");
int cc = query.record().indexOf("free_trial_correctly_validated_on");
int dd = query.record().indexOf("free_trial_start_date");
int ee = query.record().indexOf("free_trial_stop_date");
int ff = query.record().indexOf("free_trial_lasting_days");
int gg = query.record().indexOf("free_trial_issued_by");
int hh = query.record().indexOf("free_trial_license_issued_on");
int ii = query.record().indexOf("free_trial_mac_address");

int jj = query.record().indexOf("full_license_product_code");
int kk = query.record().indexOf("full_license_number");
int ll = query.record().indexOf("full_license_claimed_current_status");
int mm = query.record().indexOf("full_license_correctly_validated_on");
int nn = query.record().indexOf("full_license_licensed_to");
int oo = query.record().indexOf("full_license_email");
int pp = query.record().indexOf("full_license_telephone_number");
int qq = query.record().indexOf("full_license_issued_on");
int rr = query.record().indexOf("full_license_issued_by");
int ss = query.record().indexOf("full_license_cost");
int tt = query.record().indexOf("full_license_mac_address");

    {
        QSqlQuery query;
        query.prepare("UPDATE products SET full_license_claimed_current_status=:full_license_claimed_current_status, full_license_correctly_validated_on=:full_license_correctly_validated_on,full_license_mac_address=:full_license_mac_address WHERE id=:id");
        query.bindValue(":id", theid);
        query.bindValue(":full_license_claimed_current_status", 1);
        query.bindValue(":full_license_correctly_validated_on", date);
        query.bindValue(":full_license_mac_address", macaddress);
        query.exec();
        QMessageBox msgBox;
        msgBox.setText("Success,The License Has Been Validated.");
        msgBox.exec();

    }

但我正在

error: ambiguous overload for 'operator==' in 'full_license_claimed_current_status == 2'

当我编译。

Answer 1

你试过括号吗？

if ((ui.validateInput->text() == full_license_number) && (full_license_claimed_current_status == 2))

还有什么类型的full_license_number和full_license_claimed_current_status？

'operator =='错误的模糊重载
