休眠插入不工作

我試圖執行休眠插入SQL查詢休眠插入不工作

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();

SQL語句，但是，我得到異常下面當我試圖執行在MySQL控制檯相同的查詢，還有就是它完美地執行沒有語法錯誤

爲什麼在我調用createSQLQuery（））查詢對象後，值參數會被刪除。

如果你只打算通過連接字符串來構建一個查詢，爲什麼還要打擾hibernate呢？ – e4c5

你在你的代碼我我提的意見有些錯誤：

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();

考慮和嘗試下面的代碼片段：

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();

的調試運行，請不要給SO你的片段。閱讀What types of questions should I avoid asking?

謝謝，它的工作，但是，我不明白我到底犯了什麼錯誤 –

你的錯誤是你在查詢中傳遞'sqlQuery'而不是'sqlQuery + sql1' – Manwal

您可以嘗試直接在數據庫中執行sql語句。它會給你任何查詢錯誤。問題可能像在表名之前添加模式名稱。
