Hibernate-reactive: MS SQL: Fehler beim Einfügen einer Zeile, wenn eine Spalte eine Fremdschlüsseleinschränkung hat

Erstellt am 3. Mai 2021  ·  20Kommentare  ·  Quelle: hibernate/hibernate-reactive

Es gibt viele Tests in der HR-Suite, die Eltern-/Kind-Daten verwenden. Beispiel: EagerTest .

Bei MS SQL schlagen diese Tests fehl mit:

javax.persistence.PersistenceException: org.hibernate.HibernateException: io.vertx.mssqlclient.MSSQLException: Cannot insert the value NULL into column 'parent_id', table 'master.dbo.Node'; column does not allow nulls. INSERT fails.

Ich vermute, dass dies an der Spaltendefinition liegt:

[Hibernate] create table Node (id int not null, string varchar(255), version int, parent_id int, primary key (id))

Vielleicht sollte es explizit als NULL deklariert werden

Vielleicht sollte es explizit als NULL deklariert werden

Ich glaube nicht. Ich denke, da muss noch etwas passieren.

(Vielleicht wird eine Tabellendefinition zwischen den Tests nicht richtig gelöscht?)

Wenn ich nur org.hibernate.reactive.EagerTest#testEagerCollectionFetch auf einer neuen DB ausführe, erhalte ich:

MSSQLException: Cannot drop the table 'Node', because it does not exist or you do not have permission.]

Dies ist sicherlich der wahre Grund.

Dies ist sicherlich der wahre Grund.

Oh, tut mir leid, mein Fehler, nein, es ist nicht der Grund.

Ich habe wirklich keine Ahnung. Ich bin sicher, dass SQL Server-Fremdschlüssel standardmäßig nicht not null , also muss etwas anderes passieren.

Haben Sie versucht, dieselbe SQL vom GUI-Client auszuführen, um zu überprüfen, ob das, was ich sage, wahr ist?

gavinking picture gavinking am 3. Mai 2021

Nein, das werde ich versuchen

Es funktioniert, wenn ich dies von sqlcmd :

1> create sequence hibernate_sequence start with 1 increment by 1
2> go
1> create table Element (id int not null, node_id int, primary key (id))
2> go
1> create table Node (id int not null, string varchar(255), version int, parent_id int, primary key (id))
2> go
1> alter table Element add constraint FKcwlxr32pujpq4d7va12w278fw foreign key (node_id) references Node
2> go
1> alter table Node add constraint FKnuolrnqa3oux6ln0vkqeuhsda foreign key (parent_id) references Node
2> go
1> insert into Node (parent_id, string, version, id) values (null, 'parent',0, 1)
2> go

1> select * from Node
2> go

Sie haben also Recht, es hat nichts mit der Einschränkungsdefinition zu tun.

@tsegismont , beim Debuggen von EagerTest mit einem Haltepunkt im MSSQLException Konstruktor sehe ich ein MSSQLException mit der Meldung "Falsche Syntax in der Nähe von '?'." erstellt werden.

Diese Ausnahme scheint gefressen zu werden, und stattdessen wird ein MSSQLException mit der Meldung "Anweisung(en) konnte nicht vorbereitet werden" ausgegeben.

Ich sehe das gleiche Problem auch beim Debuggen einiger anderer Tests mit Vert.x 4.1.0-SNAPSHOT.

@gbadner Sie benötigen die Änderungen, die ich in https://github.com/DavideD/hibernate-reactive/pull/13 geteilt habe (insbesondere die Implementierung der Klasse Parameters für SQL Server).

tsegismont picture tsegismont am 4. Mai 2021

Ich werde einen Upstream-Zweig erstellen, um den Fortschritt mit dem SQL-Server zu verfolgen, damit ich ihn auf den neuesten Main umstellen kann und wir einen Referenz-Zweig mit allen Änderungen haben.

DavideD picture DavideD am 12. Mai 2021

@tsegismont wie ist der Status davon?

(Was auch immer das Problem ist, ich glaube nicht, dass die Problembeschreibung es erfasst.)

gavinking picture gavinking am 24. Mai 2021

@gavinking konnte ich noch nicht untersuchen

@gavinking Ich habe festgestellt, dass das Ändern der Dialektimplementierung das Problem behebt:

Ich weiß nicht warum, aber es scheint, dass der Server Spalten ohne NULL-Werte erstellt, wenn er nicht explizit als NULL-Werte angegeben wird (wie Sybase).

Klingelt das?

Ich meine, dieser Dialekt wird seit Jahren in Hibernate ORM verwendet, daher ist es schwer zu erkennen, wie er falsch sein könnte (es sei denn, die JDBC-Treiber des SQL-Servers machen etwas Seltsames).

gavinking picture gavinking am 25. Mai 2021

Hier ist etwas, das ich gefunden habe https://social.msdn.microsoft.com/Forums/sqlserver/en-US/16c39868-96b1-457c-a3a5-f291ba75d635/whether-a-column-is-nullable-by-default

Es scheint, dass es einige Einstellungen gibt, die dieses Verhalten beeinflussen können. Aber sie sollen standardmäßig das Richtige tun.

gavinking picture gavinking am 25. Mai 2021

Die meisten modernen Verbindungen führen automatisch ein SET ANSI_NULL_DEFAULT_ON wenn die Verbindung hergestellt wird

Vielleicht solltest du das versuchen.

gavinking picture gavinking am 25. Mai 2021

@gavinking lassen Sie mich überprüfen, ob dies an der Serverkonfiguration oder an etwas liegt, das der JDBC-Treiber tut, was der Reactive Client nicht tut.

In diesem Fall erstelle ich ein Problem im Upstream und wir können dieses schließen.

tsegismont picture tsegismont am 25. Mai 2021

@gavinking das hatte keine Wirkung.

Ich habe https://github.com/eclipse-vertx/vertx-sql-client/issues/963 eingereicht, um das Problem im Upstream zu verfolgen.

Schließen Sie diese gerne. Andernfalls können wir es später schließen, wenn das Upstream-Problem behoben ist.

OK danke. Ich glaube nicht, dass das Thema hierher gehört, also schließe ich dieses.
