How to get first day of every corresponding month in mysql?

Question

I want to get first day of every corresponding month of current year. For example, if user selects \'2010-06-15\', query demands to run from \'2010-06-01\' instead of \'2010

Answer 1

I'm surprised no one has proposed something akin to this (I do not know how performant it is):

CONCAT_WS('-', YEAR(CURDATE()), MONTH(CURDATE()), '1')

Additional date operations could be performed to remove formatting, if necessary
