Question

Is there a way to access SQLite results by column name (like a C++ Map) instead of index number in C/C++?

For example, Python’s SQLite access allows dictionary access

Results = Query("SELECT * FROM table");
print Results['colname']
print Results['anothercol'] 

Any similar methods available in C++ for the SQLite’s interface?

I’d go with Daniel in recommending SQLAPI++ at http://www.sqlapi.com — at http://www.sqlapi.com/HowTo/fetch.html you can find a simple example of fetching fields by name. The example is a bit verbose so here’s a code-only gist:

void showemps(SAConnection* pconn, int minage)
{
  SACommand cmd(pconn, "select name, age from employees where age>:1");  
  cmd << minage;
  cmd.execute();
  while(cmd.FetchNext()) {
    SAString sName = cmd.Field("name");
    long nAge = cmd.Field("age");
    printf("Name: %s, age: %d \n", sName, nAge);
  }
}
