Hi,

Hello,

Just curious over some points:

Does it support binary transfers over the wire? The library creates template expression trees for the queries. As of now, the tree is serialized and sent to the database connector when you call

db.run(query)

Result rows are currently to be returned from the connector's result object as const char**, see database_api/api.h.

You are kidding ? Is std::vectorstd::string too advanced ? Why C++ programmers are still using C null-terminated strings I will never understand. No kidding. The database client libraries I've used so far are C

BTW: These are typically not null-terminated but are delivered with a size_t* or similar to inform about the length... But: 1. As a user of the library you don't get in touch with those. The members of a row are NOT char*, of course. You get integers as integers, floats as floats and of course you get text as std::string. I wouldn't dare to use char* there ;-) 2. It would be really easy to add additional interface options so that the connector library could yield std::vectorstd::string Regards, Roland
