        // Original -I used the pointers above to populate the array at this point, but I should of just went direct into the array, instead of using the temporary pointers in between. But in theory once I free the SQL handle, the pointers are gone. So Perhaps in the future, I need to create multi part functions, one that Initializes, one that gets the data and packages it, and one that closes the handle, passing the handle to each function until complete.
