sqlite select with condition on date

Some thing like this could be used:

select dateofbirth from customer Where DateofBirth  BETWEEN date('1004-01-01') AND date('1980-12-31');  
select dateofbirth from customer where date(dateofbirth)>date('1980-12-01');
select * from customer where date(dateofbirth) < date('now','-30 years');

If you are using Sqlite V3.7.12 or greater

Dont use date(dateofbirth) just use dateofbirth. So your query would look like this:

select * from customer where dateofbirth < date('now','-30 years');
