SQLCMD创建临时表

Question

我试图从不同的SQL服务器获取数据，然后将它们插入到临时表中，然后使用SQLCMD处理数据。

我有这个过程的代码，如果你只有一个数据库，那就完美了：

DECLARE @main table(Id int identity(1,1), Country nvarchar(5), [Message] nvarchar(200), Date datetime, pcname nvarchar(200))
:connect Plant1
use Plant1
GO
INSERT INTO @main 
SELECT 'Plant1', Message, date, pcname FROM log.easyhmi WHERE DATE > GETDATE() -15 AND [Message] LIKE 'MakeChangeOver | Verify changeover runinng processInstance Id: %'ORDER BY 1 DESC
GO

:connect Plant2
use Plant2
GO
INSERT INTO @main
SELECT 'Plant2', Message, date, pcname FROM log.easyhmi WHERE DATE > GETDATE() -15 AND [Message] LIKE 'MakeChangeOver | Verify changeover runinng processInstance Id: %'ORDER BY 1 DESC
GO

:connect Plant3
use Plant3
GO
INSERT INTO @main
SELECT 'Plant3', Message, date, pcname FROM log.easyhmi WHERE DATE > GETDATE() -15 AND [Message] LIKE 'MakeChangeOver | Verify changeover runinng processInstance Id: %'ORDER BY 1 DESC
GO

--Process data here......

但如果我添加更多数据库，则无法找到@main。

有没有办法可以做到这一点？
