Its still not working for me.
row = (*i);
name = row["name"].get_string();
// mysqlpp::Null<unsigned char>
nullField(mysqlpp::null);
if(row["name"] == mysqlpp::null) {
cout << " NULL VALUE" <<
endl;
}
I am getting error
test.cpp: In function `void getName()':
test.cpp:58: error: no match for 'operator==' in
'mysqlpp::Row::operator[](const char*) const(((const char*)"name")) ==
mysqlpp::null'
/home/y/include/mysql++/const_string.h:189: note: candidates are: bool
mysqlpp::operator==(mysqlpp::const_string&, mysqlpp::const_string&)
/home/y/include/mysql++/type_info.h:329: note: bool
mysqlpp::operator==(const mysqlpp::mysql_type_info&, const
mysqlpp::mysql_type_info&)
/home/y/include/mysql++/type_info.h:342: note: bool
mysqlpp::operator==(const std::type_info&, const mysqlpp::mysql_type_info&)
/home/y/include/mysql++/type_info.h:356: note: bool
mysqlpp::operator==(const mysqlpp::mysql_type_info&, const std::type_info&)
It seems that the way I am checking for error is wrong. How do I do it
correctly. Please help.
