[Qt-interest] 答复: QTableView with summary footer

[pengliang(彭亮)]

Hi All
	Please see the snippets and output.
Why QSqlQuery execute is true, but query.isValid is false?
How can I get the error information?




-------------------- snippets
    QString str;
    str = "SELECT * FROM kblive.dbo.View_PI_在站工单查询";
    QSqlQuery query;
    qDebug() << "exec: " << query.exec(str);

qDebug() << "query.isValid: " << query.isValid();
qDebug() << "query.lastError: " << query.lastError().isValid();


---------------- output
exec:  true 
query.isValid:  false 
query.lastError:  false
