[Qt-interest] qt connect sql server

[pengliang(彭亮)]

Hi All

         Please see the snippets.

         Why query.exec(str) print true, query.isValid print false? Why? And query.lastError print false;

How do I know what is problem ,why query.isValid print false?

 

 

 

     QSqlQuery query;

     qDebug() << "exec: " << query.exec(str);

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

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

 

 

exec: true 

query.isValid: false 

query.lastError: false

 

 

 

 

thanks

ken
