Question

I am using Oracle as my database,and C++ as the language to fetch the data from the database. Let say I want to fetch data from table Customer,how should I store it? In Java, I use Vector < MyClassDefinition>. However the way to define a vector in C++ is quite complex for me. The data I fetch from the database have more than 6 column, and if I want to store it in vector, the declaration of 6 column is quite too long.

1. Is there any other way to store the data from a table in a temporary collection is C++?

2. Or I should use vector,but I am doing it wrong?

3. Or should I just use a pointer and split it into column and row by myself?

Answer 1

Have a std::vector of a class reprenting a row.

class Row
{
  int a;
  string b;
  int c;
  float f;
  double g;
  string d;
};

std::vector<Row> rows;

If some columns might be nullable, then boost::optional
