Detailed Description

template<typename T>
struct boost::sqlite::static_resultset< T >

A typed resultset using a tuple or a described struct.

Template Parameters

T	The static type of the query.

If is a forward-range with output iterators.

Example

extern sqlite::connection conn;
struct user { std::string first_name; std::string last_name; };
BOOST_DESCRIBE_STRUCT(user, (), (first_name, last_name));
 
sqlite::resultset rs = conn.query("select first_name, last_name from users;");
 
do
{
  user usr = r.current();
  handle_row(u);
}
while (rs.read_next()) // read it line by line
