i want to fetch the records matching by date of today,yesterday,last
week and last month but i dont know how to do this.

Then you need to SELECT those records where the date is between the bounds:

SELECT * FROM adds WHERE `date`
      BETWEEN
          DATE(DATE_SUB(NOW(), INTERVAL 7 DAY))
      AND DATE(DATE_SUB(NOW(), INTERVAL 0 DAY))
;

The above ought to give you last week, ending at today’s beginning at 00:00.

Note: the above works if the varchar date syntax is the same as MySQL. If it is not, you need to specifically instruct MySQL as how to parse it:

  WHERE STR_TO_DATE(`date`,'%Y:%d:%m %H:%i:%s') BETWEEN..

See date_format() for the date format syntax.
