Answer 1

SELECT * from `Table` WHERE date_format(date,"%d") = '01'

Answer 2

You can use following querys

select * from your_table_name
where `date`= DATE_FORMAT(`date` ,'2017-%m-01')

or

select * from your_table_name
where DAY(`date`)= '01' and YEAR(`date`)='2017'

Note that this will return records of every first day of months for the year 2017
