So...why are you trying to compare one of its elements to a SQL null,  
then?

If you store data from a SQL query in this array, and any of the  
values can be SQL null, you want to declare it like this:

mysqlpp::Null<std::string> awi_config[10][10].

*Then* you can compare its elements to mysqlpp::null.
