Question

以下代码嵌入在vb.net项目的.sql文件中。它给了我一个错误：

无法在sys.servers中找到服务器“DATABASE_NAME”。验证是否指定了正确的服务器名称。如有必要，执行存储过程sp_addlinkedserver以将服务器添加到sys.servers。

我检查了sys.server，如果我执行 select * from sys.servers

，则会返回LinkedDatabaseName

以下是我收到错误的代码....

Answer 1

问题是$$ DATABASE_NAME $$替换字符串的用法不一致。在大多数情况下，它用于引用特定数据库

$$DATABASE_NAME$$..txmr_TABLE1

但是在exec字符串中：

EXEC $$DATABASE_NAME$$..dbo.txmr_ExtractPOCIS

有一个太多的句号，这意味着它现在引用的是另一个服务器，而不是数据库。

将此语句更改为：

EXEC $$DATABASE_NAME$$.dbo.txmr_ExtractPOCIS

应解决问题。

在sys.servers错误中找不到服务器'DATABASE_NAME'
