Question

我有这段代码：

foreach (QString TheKeyword, KeywordsList) {
    if (!TheKeyword.isEmpty())
    {
        TheKeyword.replace("'","''").replace("[", "[[]");

        QString sQuery = QString("UPDATE news SET deleted = '1' WHERE %1 like '%%2%' AND Id IN(%3) AND deleted = '0'")
                            .arg(TheColumn)
                            .arg(TheKeyword)
                            .arg(TheIDs);

        QSqlQuery TheQuery(TheDB);
        TheQuery.prepare(sQuery);
        TheQuery.exec();

        if (TheQuery.lastError().isValid())
        {
            qDebug() << TheQuery.lastError() << "   -   " << TheKeyword;
        }
    }
}

例如，＆＃34; KeywordsList ＆＃34;包含这个单词的列表（＆＃34; KeywordsList＆＃34;是一个QStringList）：

1Tap
World
A man from Mars
2 Battery
2Do
1CLICK
01 Net
2 Bananas
4 Bananas
system app remover

我的代码返回此错误：

QSqlError("", "Unable to fetch row", "No query")    -    "1Tap"
QSqlError("", "Unable to fetch row", "No query")    -    "2 Battery"
QSqlError("", "Unable to fetch row", "No query")    -    "2Do"
QSqlError("", "Unable to fetch row", "No query")    -    "1CLICK"
QSqlError("", "Unable to fetch row", "No query")    -    "01 Net"
QSqlError("", "Unable to fetch row", "No query")    -    "2 Bananas"

所以，我发现问题只有关键字开始，其中＆＃39; 0 ＆＃39;＆＃39; 1 ＆＃39;或＆＃39; 2 ＆＃39;

我尝试使用 bindValue ，但没有成功。

谢谢。
