如果我用 HQL 写
A between 5 and 10
是否相当于
A >= 5 and A <= 10
或者
A > 5 and A < 10
或其他4种组合?
我在 Hibernate 文档中没有找到任何行为规范,但是between
HQL 中的运算符被翻译为between
SQL 中的运算符,这是包容性的。
所以between
在 HQL 中也是包容的,即
A between 5 and 10
相当于
A >= 5 and A <= 10
显然,对此存在一些混淆。自然语言会暗示它是排他性的,但事实并非如此。实际上它的 A >= 5 和 A<=10。由于已经给出了相互矛盾的答案(并且已删除),因此需要进一步澄清:(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;
