Field 'userID' doesn't have a default value問題

時間  2021-07-11 標籤 數據庫連接問題處理

字段需要設置一個默認值

Caused by: java.sql.SQLException: Field 'userID' doesn't have a default value


一、新增記錄出現異常

1.問題的出現，我在新增一個用戶信息時，報的錯誤，不能添加記錄到數據庫；



2.詳細異常信息

二、異常信息分析

1.insert語句執行失敗

    異常顯示就是insert插入sql語句執行錯誤導致添加記錄到數據庫失敗；

    根本原因就是Field 'userID' doesn't have a default value；

    字段userID沒有設置默認值；

    下面該表的create語句中確實沒有給userID設置默認值；

  
  
    
   
   
  1.  
    
     
     
     
    
     
    
     
     
     
      CREATE 
      TABLE 
      `t_user` ( 
     
     
    
    2. 
   
   
  2.  
    
     
     
     
    
     
    
     
     
     
      `userID` 
      int( 
      11) 
      NOT 
      NULL, 
     
     
    
    3. 
   
   
  3.  
    
     
     
     
    
     
    
     
     
     
      `uname` 
      varchar( 
      20) 
      default 
      NULL, 
     
     
    
    4. 
   
   
  4.  
    
     
     
     
    
     
    
     
     
     
      `userAddress` 
      varchar( 
      100) 
      default 
      NULL, 
     
     
    
    5. 
   
   
  5.  
    
     
     
     
    
     
    
     
     
     
      `userBirth` 
      varchar( 
      10) 
      default 
      NULL, 
     
     
    
    6. 
   
   
  6.  
    
     
     
     
    
     
    
     
     
     
      `userEmail` 
      varchar( 
      50) 
      default 
      NULL, 
     
     
    
    7. 
   
   
  7.  
    
     
     
     
    
     
    
     
     
     
      `userGender` 
      int( 
      11) 
      default 
      NULL, 
     
     
    
    8. 
   
   
  8.  
    
     
     
     
    
     
    
     
     
     
      `userName` 
      varchar( 
      20) 
      default 
      NULL, 
     
     
    
    9. 
   
   
  9.  
    
     
     
     
    
     
    
     
     
     
      `userPassword` 
      varchar( 
      150) 
      default 
      NULL, 
     
     
    
    10. 
   
   
  10.  
    
     
     
     
    
     
    
     
     
     
      `userPhone` 
      varchar( 
      255) 
      default 
      NULL, 
     
     
    
    11. 
   
   
  11.  
    
     
     
     
    
     
    
     
     
    
       PRIMARY 
      KEY ( 
      `userID`) 
     
     
    
    12. 
   
   
  12.  
    
     
     
     
    
     
    
     
     
    
       ); 
     
     
    
    13.

    導致insert語句對應的userID字段沒有插入數據，而該字段不允許爲null導致的；

  
  
Hibernate: insert into t_user (uname, userAddress, userBirth, userEmail, userGender, userName, userPassword, userPhone) values (?, ?, ?, ?, ?, ?, ?, ?)

三、解決異常

3-1.給字段設置默認值

    這種問題簡單的解決辦法就是設置默認值,但是當前字段userID是主鍵不能設置默認值；

  
  
`userAddress` varchar(100) default '阿拉加斯加'

3-2.Hibernate配置檢查

    那可能是Hibernate配置出現了問題；然後找到當前表對應的Entity實體類

    字段userID的配置

  
  
    
   
   
  1.  
    
     
     
     
    
     
    
     
     
     
      @Id 
     
     
    
    2. 
   
   
  2.  
    
     
     
     
    
     
    
     
     
     
      @GeneratedValue(strategy = IDENTITY) 
     
     
    
    3. 
   
   
  3.  
    
     
     
     
    
     
    
     
     
     
      @Column(name = 
      "userID", unique = 
      true, nullable = 
      false) 
     
     
    
    4. 
   
   
  4.  
    
     
     
     
    
     
    
     
     
     
      public Integer getUserId() { 
     
     
    
    5. 
   
   
  5.  
    
     
     
     
    
     
    
     
     
     
      return 
      this.userId; 
     
     
    
    6. 
   
   
  6.  
    
     
     
     
    
     
    
     
     
    
       } 
     
     
    
    7.
    該字段設置了自增策略，指定不可爲空，且是唯一的；
    感覺沒啥問題；再次測試新增一條記錄還是失敗；

3-3.數據庫中表t_user的修改

    然後就從數據表這裏入手；

    將當t_user的userID修改爲自增

  
  
alter table t_user modify userID int auto_increment;
    因爲該字段有外鍵約束不允許修改；

    索性就把表刪了；新建表t_user；直接在設置字段自增且不爲空；然後新增一條記錄成功了；

  
  
    
   
   
  1.  
    
     
     
     
    
     
    
     
     
     
      CREATE 
      TABLE 
      `t_user` ( 
     
     
    
    2. 
   
   
  2.  
    
     
     
     
    
     
    
     
     
     
      `userID` 
      int( 
      11) 
      NOT 
      NULL auto_increment,

       );

四、其他解決方法

1.修改mysql配置

    打開my.ini，查找sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"修改爲sql-mode="NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"然後重啓MYSQL

2.

    設置默認值即可，當然這個字段不是主鍵的情況下；

3.

    MySQL 5 uses a strict mode which needs to be disabled. In Windows, Goto Start-->Programs-->MySQL->MySQL Instance Config Wizard. Follow through the Reconfigure Instance option-->Detailed Configuration-->Continue Next a few screens. At the bottom under Enable TCP/IP option there is 'Enable Strict Mode'. Deslect this option (no tick). Save changes and MySQL will restart.
