Funny… I have a ResultSet object which contains an array of Column objects. Here's the basic idea:
class ResultSet {
static class Column {
int index();
string name();
int size();
int length();
void[] data();
bool opEquals(NullValue);
T as(T)(); // return raw if T matches underlying or call to!(T) on field as appropriate
}
size_t numCols();
bool nextResultSet();
bool next();
bool prev();
bool first();
bool last();
void update(); // SQLSetPos(rowNumber=0)
Column opIndex(size_t);
// easy enough to add opIndex(string)
}
Does your Row equate to the ResultSet as above?
