901  z    21-07-2018
111  a    02-07-2020

this is my table. i want to extract records of last 1 year from current date. so my output should be

 cid name   dob
    101  x    11-02-2019
    301  y    12-12-2019
    111  a    02-07-2020

Answer

In the WHERE clause set the condition that dob is greater than the current date minus 1 year:

select *
from tablename
where dob >= current_date - 1 year

If you want all the rows of the current and the previous year:

select *
from tablename
where year(current_date) - year(dob) in (0, 1)
