Question

我正在尝试执行hibernate insert sql query

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，当我在mysql控制台中尝试执行相同的查询时，我正在低于异常，没有语法错误它的执行完美

为什么在查询对象上调用createSQLQuery（）后会删除值参数。

我在您的评论中提到了一些错误：

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();

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();

您可以直接尝试在数据库中执行sql语句。它将为您提供查询的任何错误。问题可能就像在表名之前添加模式名称一样。

Hibernate插入SQL语句不起作用
