问题描述

  com.mysql.jdbc.exceptions.MySQLSyntaxErrorException:未知列'bulletin0_.bulletin_date'in'field list'

没有这样的 bulletin_date 列在我的表中,我的模型类中也没有这样的名称。它只是被称为日期

 查询查询= session.createQuery(来自公告where where approved = true这里是我得到错误的那一行。 ); 

这是我的模型类(我将getters和setters排除在外):

  public class Bulletin {
@Id
@Column(name =id)
@GeneratedValue
private int id;

@Column(name =date)
private String date;

@Column(name =name)
私有字符串名称;

@Column(name =subject)
private String subject;

@Column(name =note)
private String note;

@Column(name =approved)
private boolean approved;
}

这是我的表格定义。

  + ---------- + --------------- + ------ +  - ---- + --------- + ---------------- + 
|字段|类型|空| Key |默认|额外|
+ ---------- + --------------- + ------ + ----- + ----- ---- + ---------------- +
| id | int(11)| NO | PRI | NULL | auto_increment |
|日期| varchar(10)|是| | NULL | |
|名称| varchar(30)|是| | NULL | |
|主题| varchar(50)|是| | NULL | |
|注意| varchar(2500)|是| | NULL | |
|批准| tinyint(1)|是| | NULL | |

解决方案

我的 Bulletin.hbm.xml 文件中列名错误。当我纠正它时,问题就解决了。

I am getting the following error from my Hibernate code:

com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: Unknown column 'bulletin0_.bulletin_date' in 'field list'

There is no such bulletin_date column in my table, nor is there such a name in my model class. It's just called date. Here is the line where I'm getting the error.

Query query = session.createQuery("from Bulletin where approved = true");

Here is my model class (I'm leaving out the getters and setters):

public class Bulletin {
    @Id
    @Column(name="id")
    @GeneratedValue
    private int id;

    @Column(name="date")
    private String date;

    @Column(name="name")
    private String name;

    @Column(name="subject")
    private String subject;

    @Column(name="note")
    private String note;

    @Column(name="approved")
    private boolean approved;
}

Here is my table definition.

+----------+---------------+------+-----+---------+----------------+
| Field    | Type          | Null | Key | Default | Extra          |
+----------+---------------+------+-----+---------+----------------+
| id       | int(11)       | NO   | PRI | NULL    | auto_increment |
| date     | varchar(10)   | YES  |     | NULL    |                |
| name     | varchar(30)   | YES  |     | NULL    |                |
| subject  | varchar(50)   | YES  |     | NULL    |                |
| note     | varchar(2500) | YES  |     | NULL    |                |
| approved | tinyint(1)    | YES  |     | NULL    |                |
+----------+---------------+------+-----+---------+----------------+

解决方案

I had the wrong column names in my Bulletin.hbm.xml file. When I corrected it, the problem was solved.
