如果我用HQL编写
A between 5 and 10

相当于
A >= 5 and A <= 10

要么
A > 5 and A < 10

我没有在Hibernate文档中找到任何行为规范,但是betweenHQL中的运算符被转换为betweenSQL中的运算符,这是包含的.
所以between在HQL中也是包容性的,即
A between 5 and 10

相当于
A >= 5 and A <= 10

显然,对此存在一些困惑。自然语言表明它是排他性的,但事实并非如此。实际上它的 A >= 5 且 A<=10。由于已经给出了相互矛盾的答案(并删除了),因此需要更多澄清:(来自http://www.techonthenet.com/sql/ Between.php )
Example #1 - Numbers
The following is an SQL statement that uses the BETWEEN function:
SELECT *
FROM suppliers
WHERE supplier_id between 5000 AND 5010;
This would return all rows where the supplier_id is between 5000 and 5010, inclusive. It is equivalent to the following SQL statement:
SELECT *
FROM suppliers
WHERE supplier_id >= 5000
AND supplier_id <= 5010;
