Hibernate-reactive: MS SQL：如果列具有外键约束，则插入行时失败

创建于 2021-05-03  ·  20评论  ·  资料来源: hibernate/hibernate-reactive

HR 套件中有许多使用父/子数据的测试。 例如： EagerTest 。

使用 MS SQL，这些测试失败：

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.

我怀疑这是由于列定义：

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

也许它应该明确声明为NULL

也许它应该明确声明为NULL

我不这么认为。 我想一定还有别的事情发生。

（也许在测试之间没有正确删除表定义？）

如果我只在新数据库上运行org.hibernate.reactive.EagerTest#testEagerCollectionFetch ，我会得到：

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

这肯定是真正的原因。

这肯定是真正的原因。

哦，对不起，我的错，不，这不是原因。

gavinking picture gavinking 于 2021-05-03

我真的没有头绪。 我确定默认情况下 SQL Server 外键不是not null ，所以肯定有其他事情发生。

您是否尝试从 GUI 客户端执行相同的 SQL 以检查我所说的是否属实？

gavinking picture gavinking 于 2021-05-03

不，我会试试的

当我从sqlcmd运行它时它有效：

所以你是对的，它与约束定义无关。

@tsegismont ，在MSSQLException构造函数上使用断点调试EagerTest时，我看到MSSQLException消息“'?'附近的语法不正确。” 被创造。

该异常似乎被吃掉了，而是抛出MSSQLException带有消息“无法准备语句”的

在使用 Vert.x 4.1.0-SNAPSHOT 调试其他一些测试时，我也看到了同样的问题。

@gbadner您需要我在https://github.com/DavideD/hibernate-reactive/pull/13中分享的更改（特别是 SQL Server 的Parameters类实现）

tsegismont picture tsegismont 于 2021-05-04

我将在上游创建一个分支以跟踪 sql server 的进度，以便我可以将其重新设置为最新的主分支，并且我们可以拥有一个包含所有更改的参考分支。

@tsegismont这是什么状态？

（无论问题是什么，我都认为问题描述没有抓住它。）

@gavinking我发现改变方言实现可以解决这个问题：

我不知道为什么，但如果没有明确指定为可为空（如 Sybase），服务器似乎会创建不可为空的列。

这是否敲响了警钟？

tsegismont picture tsegismont 于 2021-05-25

我的意思是，这种方言多年来一直在 Hibernate ORM 中使用，因此很难看出它是如何出错的（除非 SQL 服务器 JDBC 驱动程序做了一些奇怪的事情）。

gavinking picture gavinking 于 2021-05-25

这是我发现的东西https://social.msdn.microsoft.com/Forums/sqlserver/en-US/16c39868-96b1-457c-a3a5-f291ba75d635/whether-a-column-is-nullable-by-default

似乎有一些设置会影响这种行为。 但默认情况下，他们应该做正确的事情。

gavinking picture gavinking 于 2021-05-25

大多数现代连接在建立连接时会自动执行SET ANSI_NULL_DEFAULT_ON

也许你应该尝试这样做。

gavinking picture gavinking 于 2021-05-25

@gavinking让我检查这是否是由于服务器配置或 JDBC 驱动程序执行而 Reactive Client 没有执行的操作。

在这种情况下，我将在上游创建一个问题，我们可以关闭这个问题。

tsegismont picture tsegismont 于 2021-05-25

@gavinking这没有任何影响。

我提交了https://github.com/eclipse-vertx/vertx-sql-client/issues/963来跟踪上游问题。

随意关闭这个。 否则，我们可以稍后在上游问题解决后关闭它。

好，谢谢。 我认为这个问题不属于这里，所以我要结束这个问题。
