Sql Server cannot retrieve data from select

[jacek]

after executing .first is False and also isValid.

The query object initially points to a place before the first record --- you have to invoke QSqlQuery::next() to fetch the data.

QSqlQuery psql("SELECT Nome FROM Anagrafica", db);
if( psql.next() ) {
   // do something with psql.value( 0 )
}
else {
   // empty result set
}

QSqlQuery psql("SELECT Nome FROM Anagrafica", db);
if( psql.next() ) {
   // do something with psql.value( 0 )
}
else {
   // empty result set
}
