QSqlQuery INSERT语句与sqlite3

Question

该查询未执行，看不到我在哪里做错了

QSqlQuery query(QString("INSERT INTO [main].[sell_log] (cart_id, title, price, amount, disscount, type, total, bill_number, whos, when) "
                    "VALUES ('%1', '%2', '%3', '%4', '%5', '%6', '%7', '%8', '%9', '%10')").arg(cart_id).arg(title).arg(price).arg(amount).arg(disscount)
                    .arg(type).arg(total).arg(bill_number).arg(whos).arg(when));
    qDebug() << query.lastQuery();
    qDebug() << query.executedQuery();

输出：

"INSERT INTO [main].[sell_log] (cart_id, title, price, amount, disscount, type, total, bill_number, whos, when) VALUES ('5', 'جديد', '7', '1', '0', 'سعر البيع', '7', '151', '1', '23-10-2016')"
""

Answer 1

解决了 ：

QSqlQuery query(QString("INSERT INTO [main].[sell_log] (cart_id, title, price, amount, disscount, type, total, bill_number, whos, 'when') "

问题是“何时”，因为何时是sql语句，所以我需要转义
