如何从HQL for Oracle中获取日期开始的年份

Question

List employees = session.createQuery("FROM Employee where date1 between '04-APR-04 02.27.05.187000 AM' and '04-APR-14 02.27.05.187000 AM' and YEAR('04-APR-04 02.27.05.187000 AM')=YEAR('04-APR-04 02.27.05.187000 AM')").list();

I am getting this Issue:

    Hibernate: select emThrployee0_.id as id2_, employee0_.firstName as firstName2_, employee0_.lastName as lastName2_, employee0_.date1 as date4_2_ from emp1 employee0_ where (employee0_.date1 between '04-APR-04 02.27.05.187000 AM' and '04-APR-14 02.27.05.187000 AM') and extract(year from '04-APR-04 02.27.05.187000 AM')=extract(year from '04-APR-04 02.27.05.187000 AM')

Answer 1

Implicit conversions aren't as accomidating in Oracle as they are in SQL Server. Look at stuffing your date time strings into the TO_DATE() function in your query.

http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions183.htm

Answer 2

I would try reading the documentation because your query should be structured this way:

Select * FROM table t WHERE t.column...

You can try something like the following:

"SELECT * FROM Employee e WHERE e.date1 > '2013-01-01' AND e.date1 <'2014-01-01'"

This will get all columns from your employee table and you can experiment with dates in these formats. Using those formats you can use the function YEAR(date) .
