hibernate - 来自给定 SQL 查询的 HQL 查询

Question

我得到了这样的 SQL 查询：

SELECT COUNT(count) as ovcount from (SELECT COUNT(id) AS count FROM table WHERE
field1=value1 and field2=value2 GROUP BY something1, something2, something3)
as T WHERE count > 1

该语句在 HQL 中的外观如何？如果查询在 FROM 之后包含子查询，Hibernate 不支持“简单方法”。

Answer 1

最后，我认为您要做的是仅在总数高于 1 时获取 COUNT(id) 。使用HAVING应该会给您相同的结果。

SELECT COUNT(id) AS count 
FROM table 
WHERE field1=value1 and field2=value2 
GROUP BY something1, something2, something3
HAVING COUNT(id) > 1
