I have found a fix to the SQLQuerry::insert() problem for VC++ 7.1

You need to use an explicit cast...

(static_cast<std::stringstream&>(*this))

So the method will look like....

template <class T> SQLQuery& insert(const T &v) {

reset();

(static_cast<std::stringstream&>(*this)) << "INSERT INTO " << v.table() << " (" << v.field_list()

<< ") VALUES (" << v.value_list() << ")";

return *this;

}

Here is a link to a very good explanation of the bug and work around...
