postgresql 按日期范围查询,postgresql日期


按照日期范围查询有好几种方法,日期字段类型一般为:

Timestamp without timezone

方法一:

select * from user_info where create_date >= '2015-07-01' and 
create_date < '2015-08-15';

方法二:

select * from user_info where 
create_date between '2015-07-01' and '2015-08-15';

方法三:

select * from user_info where 
create_date >= '2015-07-01'::timestamp  
and create_date < '2015-08-15'::timestamp;

方法四:

select * from user_info where create_date 
between to_date('2015-07-01','YYYY-MM-DD') 
and to_date('2015-08-15','YYYY-MM-DD');
