Fetches one row of data from the result set and returns it as an array of char pointers (MYSQL_ROW), where each column is stored in an offset starting from 0 (zero). Each subsequent call to this function will return the next row within the result set, or NULL if there are no more rows.
If a column contains a NULL value the corresponding char pointer will be set to NULL.
Memory associated to MYSQL_ROW will be freed when calling mysql_free_result() function.
