mysql - how to filter based by current year and lastyear? -

-

i have table year values ('2013','2014','2015','2016')

i want filter values current year , last year results of searching current yea , last year ('2016','2015') how filter based current year , lastyear?

you can use year() function:

where col in (year(curdate()), year(curdate()) - 1)

however, if column contains strings, should convert these strings performance reasons:

where col in (date_format(curdate(), '%y'),               date_format(date_sub(curdate(), interval 1 year), '%y')              )
