VS2010 / MSSQL-引用另一个数据库服务器的主服务器

Question

I have a VS 2010 solution that contains two database projects, FirstDatabase and SecondDatabase . Each has a database reference to master and msdb , and FirstDatabase has a reference to SecondDatabase .

In the execution environment, the two databases are on separate servers. Therefore, in VS2010, FirstDatabase 's reference to SecondDatabase is defined with a server variable name $(OtherServer) .

FirstDatabase contains a function executeIfUp() that tests whether SecondDatabase on OtherServer is up:

create function executeIfUp() returns int as 
begin
 declare @value int
 set @value = 0
 if (select [state] from [$(OtherServer)].master.sys.databases where [name] = 'SecondDatabase') = 0
 begin /* do stuff */ end
 return @value
end

The problem is that VS2010 complains of a missing reference:

SQL04151: Function: [dbo].[executeIfUp] has an unresolved reference to object [$(OtherServer)].[master].[sys].[databases].[name].

This is apparently happening because VS2010 does not interpret [$(OtherServer)].master to be a reference to the master database (which nominally has the same schema on all MSSQL servers). If I add an additional database reference to [$(OtherServer)].master to FirstDatabase 's database project, I get an error saying that there are duplicate references to master in FirstDatabase 's database project.

My question is: how do I get VS2010 to resolve [$(OtherServer)].master as a valid reference?

Answer 1

From the documentation you referenced "If you refer to an object in a database project on another server, you must define it as a linked server on your target server" (see http://technet.microsoft.com/en-us/library/ff772782.aspx ). Also make sure that $(OtherServer) is setup as a Variable.

1. Click Define server variable.
2. In Name, type a name for the variable that represents the server.
3. In Value, type the name of the server that the variable represents.

Answer 2

在Visual Studio 2012中（我不知道它是否适用于2010），您可以右键单击数据库项目，添加数据库引用，选择系统数据库，然后选择“主”。
