date greater than a specified date (date, month, year)

Question

对于包含int字段date，month和year的数据库表，查询大于指定日期的行的最佳方法是什么？

Answer 1

You can do:

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');

See sqlite select with condition on date

Answer 2

通过简单的算术，您可以像这样进行选择：

SELECT * FROM t WHERE year*10000+month*100+day>20131021;
