Postgresql:在 playframework 1.x 中选择两个日期之间的所有数据

Question

我有一个 postgresql 表，其中包含与日期相关的数据。每行都有数据和日期，例如:

2011-02-03    JOHN   Male   etc

I am using playframework. i have created a model named student.java.

and in application.java i have done something like this where firstDate and lastdate are given by user,

List (student studentList) = student.find("timestamp BETWEEN 'firstDate' and 'lastDate'").fetch();

我想获取这两个日期之间的所有数据。

但我知道查询不正确。请帮帮我。

提前致谢。 :)

Answer 1

public static final List<Student> findWithDates(Date firstDate, Date lastDate) {
  return find("from Student student where student.date >= ? and student.date <=?",
              firstDate, lastDate).fetch();
}
