I am getting the below error, when I try to add a app and app settings. Here is the detailed error message:

    2015-12-21 21:23:15 ERROR SqlExceptionHelper:146 - Column 'company_id' cannot be null

Here is the junit test

@Test
    public void testsSaveApps() {
        List<AppSetting> settings = new ArrayList<AppSetting>();
        //int settingid = types.getMaxSettingId()+1;
        settings.add(createSettingsOne());
        settings.add(createSettingsTwo());
        assertEquals(true,types.addTVappsWithSettings( 1,13, "App1", settings, "Danka" ) );
        
    }
    
    private static AppSetting createSettingsOne(){
        
        AppSetting setting = new AppSetting();
        setting.setCreated_by("Kasun");
        LocalDateTime time = new LocalDateTime();
        setting.setCreated_time(time);
        setting.setDisplayOrder(1);
        setting.setEditable(true);
        setting.setSettings_key("url");
        setting.setSettings_value("www.google.com");
        setting.setUpdated_time(time);
        setting.setUpdated_by("Kasun");
        //setting.setSettings_id(settingid);
        return setting;
    }
    private static AppSetting createSettingsTwo(){
        
        AppSetting setting = new AppSetting();
        setting.setCreated_by("Kasun");
        LocalDateTime time = new LocalDateTime();
        setting.setCreated_time(time);
        setting.setDisplayOrder(2);
        setting.setEditable(true);
        setting.setSettings_key("url2");
        setting.setSettings_value("www.CBC.com");
        setting.setUpdated_time(time);
        setting.setUpdated_by("Kasun");
        //setting.setSettings_id(settingid);
        
        return setting;
    }

This is the app and settings saving method

public boolean addTVappsWithSettings(int appTypeId,int companyid, String appName, List<AppSetting> settings, String createdBy) {
    //set properties of the app to persist
    App app = new App();

    //app.setSettings_id(settingid);
//  app.setSettings_id(settingid);
    app.setApp_id(appTypeId);
    app.setCompany_id(companyid);
    app.setApp_name(appName);
    app.setCreated_by(createdBy);
    LocalDateTime created_time = new LocalDateTime();
    app.setCreated_time(created_time);
    app.setUpdated_by(createdBy);
    app.setUpdated_time(created_time);
    app.setEnable(true);
    app.setapps(settings);
    session.save(app);
    if (!HibernateUtil.INSTANCE.commitTransaction())
        return false;
    return true;
}

These are DAO classes.

@Entity
@Table(name="company")
public class Company {
    @Id  //primary key
    @GeneratedValue(strategy = GenerationType.IDENTITY)//strategy for generating auto generated number
    @Column(name= "company_id", nullable = false)
    private int company_id; 
    
    @OneToMany(fetch = FetchType.EAGER,cascade = CascadeType.ALL)
    @Fetch(value = FetchMode.SUBSELECT)
    @JoinColumn(name = "company_id", nullable = false)
    private List<App> threatviewapps = new ArrayList<App>();
    
    @NotEmpty
    @Column(name= "short_name", nullable = false)
    private String short_name;
    
    @NotEmpty
    @Column(name= "company_description", nullable = false)
    private String company_description;
    
    @NotEmpty
    @Column(name= "company_name", nullable = false)
    private String company_name;
    
    @Type(type="org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")
    @Column(name= "created_time", nullable = false)
    private LocalDateTime created_time;
    
    @Column(name= "created_by", nullable = false)
    private String created_by;
    
    @Type(type="org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")
    @Column(name= "update_time", nullable = false)
    private LocalDateTime update_time;

    @Column(name= "updated_by", nullable = false)
    private String updated_by; 
    
    @Column(name= "enable", nullable = false)
    private boolean enable;

This is the App DAO

@Entity
@Table(name = "apps")
public class App {

    @Id // primary key
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    @Column(name = "settings_id", insertable = false, updatable = false)
    private int settings_id;
    

    @Column(name = "app_id", nullable = false)
    private int app_id;

/*  @OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    @JoinColumn(name = "settings_id", nullable = false)
    private List<AppSetting> tvsettings = new ArrayList<AppSetting>();*/

    @ElementCollection
    @CollectionTable(name="threatview_app_settings",joinColumns = @JoinColumn(name = "settings_id"))
    private List<AppSetting> tvsettings = new ArrayList<AppSetting>();
    
    
    @Column(name = "company_id", insertable = false, updatable = false)
    private int company_id;

    @Column(name = "app_name", nullable = false)
    private String app_name;

    @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")
    @Column(name = "created_time", nullable = false)
    private LocalDateTime created_time;

    @Column(name = "created_by", nullable = false)
    private String created_by;

    @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")
    @Column(name = "updated_time", nullable = false)
    private LocalDateTime updated_time;

    @Column(name = "updated_by", nullable = false)
    private String updated_by;

    @Column(name = "enable", nullable = false)
    private boolean enable;

Why do I get the above error? If you guys need any more information, please let me know.

Update

@Entity
@IdClass(SettingIDKey.class)
@Table(name = "app_settings")
public class AppSetting {


    @Id
    private int settings_id;
    
    @Id
    private String settings_key;
  

    @Column(name = "settings_value", nullable = false)
    private String settings_value;

    @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")
    @Column(name = "created_time", nullable = false)
    private LocalDateTime created_time;

    @Column(name = "created_by", nullable = false)
    private String created_by;

    @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")
    @Column(name = "updated_time", nullable = false)
    private LocalDateTime updated_time;

    @Column(name = "updated_by", nullable = false)
    private String updated_by;

    @Column(name = "editable", nullable = false)
    private boolean editable;

    @Column(name = "enable", nullable = false)
    private boolean enable;
    
    @Column(name = "display_order", nullable = false)
    private int displayOrder;

  • You are passing in a `null` value. You are in the best position to _debug_ your code and determine where in your test this is happening. – Tim Biegeleisen Dec 22 '15 at 06:19
  • I have been trying to solve this for 24 hours but no luck. – newday Dec 22 '15 at 06:22
  • company_id was null. Maybe check your code again. `could not execute statement [n/a] com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Column 'company_id' cannot be null` – Jörn Buitink Dec 22 '15 at 06:38
  • I assume that hibernate mapping is not correct, I have checked the code. I exactly pass the company id. `org.hibernate.exception.ConstraintViolationException: could not execute statement at ` – newday Dec 22 '15 at 06:57

In your case you have made OneToMany as owning side for company_id. i.e, Company class is owning side.

In this scenario inserting a App record results in two queries one insert and one update. First is the insert statement that performs an insert into App table without company_id (as this is not owning side) and then it fires an update query to update the company_id. So for the first insert statement to succeed it requires company_id to be a null field in database. Else it will throw ConstraintViolationException.

If you make ManyToOne as owning side, then it results in a single insert statement in App table. So company_id field can be null in this case.

So with this, I see two options:

  1. Either make company_id as null field in database.
  2. Make ManyToOne as owning side.

The below output helps in understanding the above statements. I have Forest class which has OneToMany relation with Tree class.

WITH MANY-TO-ONE SIDE OWNING 

Hibernate: values identity_val_local()
Hibernate: insert into Tree (id, "COUNT", FOREST, name, version) values (default, ?, ?, ?, ?)

WITH ONE-TO-MANY SIDE OWNING 

Hibernate: insert into Tree (id, "COUNT", name, version) values (default, ?, ?, ?)
Hibernate: values identity_val_local()
Hibernate: update Tree set FOREST=?, index=? where id=?

  • I tried, the first option but I didnt do the second option as I need a one-to-many realtionship. – newday Dec 22 '15 at 17:39
  • @mankadanka Were you able to resolve the issue with first option. Also, even with second option you will still have one-to-many relationship and oneToMany side will be the owing it. – Madhusudana Reddy Sunnapu Dec 22 '15 at 17:46
  • I coudnt do that with first option. – newday Dec 22 '15 at 17:49
  • @mankadanka are you getting the same "MySQLIntegrityConstraintViolationException: Column 'company_id' cannot be null" or a different one. If you are getting the same exception it may be worth cross-checking whether you have actually made company_id column of apps table nullable. If you are getting a different exception, posting it would help us. – Madhusudana Reddy Sunnapu Dec 22 '15 at 18:14
  • I think App is the owning side because, it has foriegn key of companyid refere to Company table. – newday Dec 22 '15 at 18:26
  • You are right from the database perspective, as App owns or contains company_Id column. But at a hibernate mapping level you can define which side is owner/owns the relationship. In your case you have defined Company entity owns the relationship.

  • your link help me to solve lot of issues. basically, I removed the @joincolumn annotation and used mappedby. However app_settings settings_id value doesnt get app settings_id. it is always 0. do you have any clue? – newday Dec 22 '15 at 21:59
  • @mankadanka With mappedBy you are effectively using ManyToOne as owning side i.e., our Option 1. Regarding settings_id being 0, can you check whether you have marked AppSetting class as `@Embeddable`. Can you post AppSetting class as well. – Madhusudana Reddy Sunnapu Dec 23 '15 at 02:37
  • I added the setting class too.Adding @Embaddable didn't solve the issue. I still get the same error message. – newday Dec 23 '15 at 17:32
  • Once you add @Embeddable annotation to AppSetting class you need to make few more changes, not sure if you have made those changes. So with `@Embeddable` you need to remove `@Entity` association & `@IdClass` annotations. Remove both private int settings_id & private String settings_key. Can you try with these changes. In case you want AppSetting to use `@Entity` it needs to be a oneToMany mapping in App rather than `@ElementCollection`.

The problem seems to be in App.java

@Column(name = "company_id", insertable = false, updatable = false)
private int company_id;

By setting insertable = false you're telling Hibernate not to include it in the INSERT statement. With that and updatable = false you can never set it without explicit queries.

  • If I remove the settings, I get following error message.org.hibernate.MappingException: Repeated column in mapping for entity: com.xxx.dao.App column: company_id (should be mapped with insert="false" update="false") – newday Dec 22 '15 at 17:38
  • That occurs in the other class, where you've defined two columns with that name. ` @JoinColumn(name = "company_id", nullable = false)` tells it the local column, not the remote one. You need that one in the `App` class, not `Company`, if you decide to have the company as an object on the `App` side, instead of just an id. I also recommend adding `mappedBy = "apps"` to the `OneToMany` annotation on `threatviewapps`. I'm checking with a working example for these. Just as a stylistic note, you don't have to name your fields with underscores, if you're also going to name them using annotations. – coladict Dec 22 '15 at 20:53

in your form look at the name of the company_id antite is it the same with what is in the database. If yes, you must give the company id at the form level.

If you are creating a non-nullable variable but missed to give the values or default values it will throw this error.

Example:

 @Column(name = "number_of_reschedules", nullable = false, columnDefinition = "NUMBER(10) default 0")
 private Integer numberOfReschedules;

In this example, I create this column with "nullable = false". But I missed to give default value.
