Question

I need to count two data in same table for 2 time periods.
I tried something like this:

SELECT COUNT(CASE
                 WHEN click_date='2011-06-20' THEN 0
                 ELSE 1
             END) AS ThisDayCount, COUNT(1) ToDayCount
FROM MyTable
WHERE click_date BETWEEN '2011-05-01'AND 2011-06-20;

So basically i want to have count from one day as ThisDayCount and count from 2011-05-01 to 2011-05-20

click_date is a String.

SELECT COUNT( CASE
                  WHEN click_date='2011-06-20' THEN 1
                  ELSE NULL
              END ) AS ThisDayCount
     , COUNT(*) AS ToDayCount
FROM MyTable
WHERE click_date BETWEEN '2011-05-01' AND '2011-06-20' ;
