Re: RFC C++ Interface

Interesting comments.  I can see using the STL framework for iterating
through result sets being one way to go.  Would something like:

vector<pgrows>table = pgdb.exec("Select * from foo");
vector<pgrows>::iterator row;
vector<pgrows>::iterator end = table.end();

for( row = table.begin(); row != end; ++row ) {
 *row >> field1 >> field2;
 //do something with fields

}

be along the lines you were thinking?

Cheers,

Randy
