26/4/2010, 7, 31929, 27, 57812

All help are much appreciated! Thanks in advance.

Answer 1

Basics would be to use SUM and CASE, something like:
SELECT
DATEADD(day,DATEDIFF(day,'20010101',DateTimeActivity),'20010101') as Date,
SUM(CASE WHEN Charges > 2500 THEN 1 ELSE 0 END) as Count2500,
SUM(CASE WHEN Charges > 2500 THEN Charges END) as Sum2500,
COUNT(*) as CountTotal,
SUM(Charges) as SumTotal
FROM
AccActivity
WHERE
DateTimeActivity >= '20100401' and
DateTimeActivity < '20100501'
GROUP BY
DATEADD(day,DATEDIFF(day,'20010101',DateTimeActivity),'20010101')
Updated based on your comment, to use real table/column names. I assume you want to include transactions which occur on 30th April.
Note that I'm using a safe date format for my date literals (YYYYMMDD) - most other formats are ambiguous based on the regional settings on the server.
Also, I'm using DATEADD(day,DATEDIFF(day,'20010101',DateTimeActivity),'20010101') to strip the time component from the datetime - it looks slightly funky, but it's reasonable fast, and the same pattern can be used to do other datetime conversions relatively easily (e.g. if you need to group on months, you can just change both day options to month, and the dates will all be set to the 1st of their respective month)

Answer 2

You can try with:
SELECT date,
count(if(charges>2500, 1, NULL)) as countGt2500,
sum(if(charges>2500, charges, 0)) as totalGt2500,
count(charges) as countTotal,
sum(charges) as sumTotal,
FROM yourTable
WHERE date >= '2010/04/01'
AND date <= '2010/04/30'
GROUP BY date;
If you saved the full datetime on the field date you have to extract the date part from the datetime, to do it you can use the DATE function on the following way:
SELECT DATE(date) as day,
count(if(charges>2500, 1, NULL)) as countGt2500,
sum(if(charges>2500, charges, 0)) as totalGt2500,
count(charges) as countTotal,
sum(charges) as sumTotal,
FROM yourTable
WHERE date >= '2010/04/01'
AND date <= '2010/04/30'
GROUP BY day;
