    OraOpen(cCursor, hConnection);
    OraParse(cCursor, sqlSelect);
    OraBind(cCursor, ":1", SQLT_INT);
    OraSetInt(cCursor, ":1", 25);
    OraDefine(cCursor, 1, SQLT_CHR, 32);
    OraDefine(cCursor, 2, SQLT_INT);
    OraExec(cCursor);
    
    while OraFetch(cCursor) do
      sName := OraGetString(cCursor, "1");
      nAge := OraGetInt(cCursor, "2");
      write(sName, 32); write(nAge, 5); writeln;
    end;
