Java 更新hibernate org.hibernate.hql.internal.ast.QuerySyntaxException中的表时

我尝试上传.xls文件。我从该文件中获取值，然后更新表

我试图用一个条件更新一个表，该条件在两个表中是唯一的。 在更新时，我得到了以下异常

"org.hibernate.hql.internal.ast.QuerySyntaxException: expecting "set", found ','" 

我将在此处显示我的逻辑代码。
Controller.java

    HSSFSheet worksheet = workbook.getSheetAt(0);

//                                    int challan= this.epzdao.getChallannoplusone(req);

                            for(int i=0;i < worksheet.getPhysicalNumberOfRows()-1;i++)

                                HSSFRow row = worksheet.getRow(i + 1);
                                //Sets the Read data to the model class

由于更新时不能在

HQL

中使用

JOIN

，因此可以使用

子查询

看看这里

您可以尝试此查询，也可以根据需要进行修改

Update Challan_dc p
SET 
p.taxablevalue =:field1, p.cgstrate =:field2, p.cgstamt =:field3, p.sgstrate =:field4, p.sgstamt =:field5, p.igstrate =:field6, p.igstamt =:field7, p.status =:field10  
where  
q.isbn =:field8  
and p.challanno = :field9  
and p.jobDocketId IN ( select q.jobdocketid from Sales q );
//OR
and p.jobDocketId = ( select q.jobdocketid from Sales q where some conditon);

我们需要基于父表和子表创建hibernate映射文件.hbm。因为对父表的更新也会导致子表的更新。

如何合并数据？？使用em.merge或executeUpdate（）？？executeUpdate（）你能更新代码吗？这样我就能帮你了

Update Challan_dc p
SET 
p.taxablevalue =:field1, p.cgstrate =:field2, p.cgstamt =:field3, p.sgstrate =:field4, p.sgstamt =:field5, p.igstrate =:field6, p.igstamt =:field7, p.status =:field10  
where  
q.isbn =:field8  
and p.challanno = :field9  
and p.jobDocketId IN ( select q.jobdocketid from Sales q );
//OR
and p.jobDocketId = ( select q.jobdocketid from Sales q where some conditon);
