Solution 1

Try the following query for result. For date range you can generate a string for respective date.

select *
from
(
  select attendance, `date`
  from AttendanceRecord
) src
pivot
(
  COUNT(`date`)
  declare date cursor for `2020-01-01`, `2020-02-01`, `2020-03-01`, `2020-04-01`)
) piv

This does not look like MySql query. This is MS SQL query.
Please, improve it or delete it to avoid down-voting.
