Java Hibernate insert SQL语句不工作

我正在尝试执行hibernate插入sql查询

String sqlQuery = "insert into examschedule (class_id,examtype_id,subject_id,examdate,start_time,end_time,messagetype_id,createddate) values";
   String sql1 =sql1+ "("+ classes.getId()+","+
                            exType.getId()+","+
                            subjectName.getId()+","+
                            "'"+sqlDate+"'"+","+"'"+startTime+"'"+","+"'"+endTime+"'"+","+msgType.getId()+","+"'"+sqlTimestamp+"'"+");";

 System.out.println(sqlQuery+sql1);
                query = session.createSQLQuery(sqlQuery);
                int result = query.executeUpdate();

但是，当我尝试在mysql控制台中执行同一个查询时，我遇到了以下异常：它的执行是完美的，没有语法错误

为什么在我调用查询对象上的createSQLQuery（）时会删除该值参数

我在评论中提到的代码中有一些错误：

String sqlQuery = "insert into examschedule (class_id,examtype_id,subject_id,examdate,start_time,end_time,messagetype_id,createddate) values";
   String sql1 =sql1+ "("+ classes.getId()+","+
               //^^ here you are adding undefined value remove it
                            exType.getId()+","+
                            subjectName.getId()+","+
                            "'"+sqlDate+"'"+","+"'"+startTime+"'"+","+"'"+endTime+"'"+","+msgType.getId()+","+"'"+sqlTimestamp+"'"+");";

 System.out.println(sqlQuery+sql1); //complete query is in sqlQuery+sql1
 query = session.createSQLQuery(sqlQuery); //here you are passing half query use sqlQuery+sql1
 int result = query.executeUpdate();

请考虑并尝试以下代码段：

String sqlQuery = "insert into examschedule (class_id,examtype_id,subject_id,examdate,start_time,end_time,messagetype_id,createddate) values";
   sqlQuery = sqlQuery + "("+ classes.getId()+","+
                            exType.getId()+","+
                            subjectName.getId()+","+
                            "'"+sqlDate+"'"+","+"'"+startTime+"'"+","+"'"+endTime+"'"+","+msgType.getId()+","+"'"+sqlTimestamp+"'"+");";

 System.out.println(sqlQuery);
 query = session.createSQLQuery(sqlQuery);
 int result = query.executeUpdate();

调试代码片段时，请不要使用

您可以尝试直接在数据库中执行sql语句。它将为您提供任何查询错误。问题可能类似于在表名之前添加架构名。

如果您只想通过连接字符串来构建查询，为什么还要使用hibernate呢？谢谢，它工作了，但我不明白我到底犯了什么错误。您的错误是在查询中传递

sqlQuery

，而不是

sqlQuery+sql1
