Question

我尝试上传.xls文件。从该文件中我获取值，然后更新表。

尝试使用两个表唯一的条件更新表。在更新时，我得到了以下异常

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

我将在这里显示我的逻辑代码 Controller.java

    HSSFSheet worksheet = workbook.getSheetAt(0);

//                                    int challan= this.epzdao.getChallannoplusone(req);
//                          //Reads the data in excel file until last row is encountered
                            for(int i=0;i < worksheet.getPhysicalNumberOfRows()-1;i++)
                            {

//                              //Creates an object representing a single row in excel
                                HSSFRow row = worksheet.getRow(i + 1);
                                //Sets the Read data to the model class

由于您在更新时无法在JOIN中使用HQL，因此您可以使用Subqueries代替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);。

您可以尝试此查询，也可以根据需要进行修改。

我们需要根据父表和子表创建hibernate映射文件.hbm。因为父更新也会导致子更新。

在hibernate org.hibernate.hql.internal.ast.QuerySyntaxException中更新表时
