为“字符串之间”创建休眠限制

Question

I'd like to compare if a String is greater than or equal and less than or equal another two Strings.

Example:

"C" between "A" and "F" > true

I tried:

Criteria criteria = session.createCriteria();
criteria.add(Restrictions.ge("START_VALUE_COLUMN", "C")) 
        .add(Restrictions.le("END_VALUE_COLUMN", "C"));

But that's not working for me.

How can I add this Restriction in Hibernate?

Answer 1

I think you have you have swapped the operators.

Your criteria results in:

... where START_VALUE_COLUMN >= "C" and END_VALUE_COLUMN <= "C"

Turn them around:

Criteria criteria = session.createCriteria();
criteria.add(Restrictions.le("START_VALUE_COLUMN", "C")) 
        .add(Restrictions.ge("END_VALUE_COLUMN", "C"));
