Answer 1

If you want to count the number of records in your table, simply run:

    SELECT COUNT(*) FROM your_table;

Answer 2

If what you want is the total number of records in the table appended to each row you can do something like

SELECT *
  FROM my_table
  CROSS JOIN (SELECT COUNT(*) AS COUNT_OF_RECS_IN_MY_TABLE
                FROM MY_TABLE)

You'd want something like

SELECT somecolumn,someothercolumn, COUNT(*) 
   FROM my_table 
GROUP BY somecolumn,someothercolumn
