sqlite选择条件日期 [英] sqlite select with condition on date

问题描述

我有一个sqlite表与出生日期。我想执行一个查询来选择那些年龄大于30的记录。
我尝试了下面但是不工作：

  select * from mytable where dob> '1 / Jan / 1980'
 select * from mytable where dob> '1980-01-01'
  

解决方案

可以使用：

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

如果您使用的是Sqlite V3.7.12或更高版本

不要使用日期（dateofbirth）只需使用 dateofbirth 。因此，您的查询将如下所示：

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

I have an sqlite table with Date of Birth. I would like to execute a query to select those records where the age is more than 30. I have tried the following but it doesn't work:

select * from mytable where dob > '1/Jan/1980'
select * from mytable where dob > '1980-01-01'

解决方案

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');
