Hibernate查询不返回零值

Question

在SQL中使用相同的查询

Select count(tbl_leads.lead_Status_Id) , tbl_LeadStatus.LeadStatus_Type FROM tbl_LeadStatus LEFT JOIN tbl_leads ON tbl_LeadStatus.LeadStatus_id = tbl_leads.lead_Status_Id GROUP BY tbl_LeadStatus.LeadStatus_Type;

Hibernate查询

Select s.LeadStatus_Type, count(l.status) FROM Status s "
                + "LEFT JOIN Lead l ON l.status = s.LeadStatus_id "
                + "GROUP BY s.LeadStatus_Type"

期待输出是这个

   Count  LeadStatus_Type
    '0'   'Cancelled' 
    '0'   'In-Progress' 
    '1'   'New' 
    '0'   'Sold' 
    '0'   'UnAssigned' 

HQL返回此

'1', 'New' 

Answer 1

您的加入条件已关闭。在HQL中，我们从实体加入另一个实体，该实体作为第一个实体的属性存在。最重要的是，没有ON子句，因为这种关系在Hibernate中是已知的。请尝试以下方法：

SELECT s.LeadStatus_Type, COUNT(l.status)
FROM Status s
LEFT JOIN s.LeadStatus_id l
GROUP BY s.LeadStatus_Type
