实体框架更新大表失败 - 异常：等待操作超时

Question

实体框架 6.1.3 更新大表在生产环境中失败

例外：

等待操作超时

我有一个包含近 8000000 条记录的Issue表。 插入记录时出现异常

等待操作超时

在插入记录时，我们在 SQL 事务中执行一些后台任务。

1. 在Notification表中插入值（向用户发送通知）。
2. 在Change表中插入值。 Change表保留了历史更改值、旧值、新值等。我认为这个事务会导致超时异常。 需要一些输入

Answer 1

不确定您使用的是什么版本的 EF，但不管您是否需要设置命令超时。 它默认为 30 秒，因此对您不起作用。

在 EF 6 中，它是这样设置的： this.context.Database.CommandTimeout = 0; EF 5，类似这样： ((IObjectContextAdapter)this.context).ObjectContext.CommandTimeout = 0; 在 EF 核心中： this.context.Database.SetCommandTimeout(0);

该值以秒为单位。 如果将该值设置为 0，则为“无限制”。 我会说这就是你所需要的。
