Thank you!

This was more helpful than the documentation on MySQL++’s site.

How would you store a field’s value into a std::string variable though? I passed it through a stringstream since I couldn’t figure it out.

Thanks again

just letting you know how to convert mysqlpp::string to QString


StoreQueryResult ares = query.store();

for (size_t i = 0; i append("sss" + QString::fromLatin1(ares[i]["login"]));
}

hope above code will be formatted correctly this time.

sorry for bombarding this post here my need more help. I was able to solve my above issue with missing StoreQueryResult thing. I was using 2.3.2 of mysql++ lib had to reemerge to unstable 3.0.9 (gentoo OS) my netbeans still highlight the StoreQueryResult as “Unable to resolve identifier” but its g++ compile just fine.

I have another problem, I us qt gui and need to display results from DB in text area so use widget to make this happen but see the error please on below code

StoreQueryResult ares = query.store();
for (size_t i = 0; i append(ares[i]["login"]);
}

error: no matching function for call to ‘QTextEdit::append(const mysqlpp::String&)’

how to convert that ??

Using Result instead of StoreQueryResult I got working this:

Result result = query.store();

if (result) {
mysqlpp::Row row;
mysqlpp::Row::size_type i;

for (i = 0; i append(row.raw_data(1));

}
}

I still investigate why StoreQueryResult is not enabled.

So I have tried Result

Result ares = query.store();

that worked out, not sure why this should be replaced to StoreQueryResults, but any way now have different error :

error: no match for ‘operator[]’ in ‘ares[0]’

what is going on ?!?!, wrrrrr

Please help
