Hi,

When you execute a query using QSqlQuery, and it generates an error, Then you can use the QSqlQuery::lastError() to get the QSqlError, Now if the number() returns -1, it just means that there wasn't any error.

cann't you use ..



int QSqlError::type () const


then check it..

if( type() == QSqlError::None ) //if no error
else if type() == QSqlError::Connection ) // if connection error

----etc

or Try the lastError() as sunil said.

For more usability use QSqlError::showMessage()
