我已经创建了数据库迁移，在Up方法中我想用SqlFile方法执行sql文件。每个文件包含2个语句：第一个drop procedure（如果存在），第二个是create procedure。两个语句都以GO结束。这是例外，我试图应用迁移时得到了：

存储过程包含对链接服务器的请求，这可能是问题的原因吗？
修改
Up方法非常简单：
public override void Up()
{
SqlFile(@"Sql\sp_MergeData.sql");
}
我调查过与SP内部的代码有关。我试图让它变得尽可能简单，之后我就没有错误。带有merge语句和链接服务器的SP选择。
编辑2
我发现此问题的原因是从链接服务器表创建同义词，因此在执行SP代码之前，数据库中没有。有解决方法吗？
编辑3
我的团队成员的机器上不存在问题所以我暂时保留原样。
答案 0 :(得分：0)
修复了将true传递给非必需参数suppressTransaction
