将数据从一张表导入到另一张表

I am using SQL Server 2008 Enterprise. I need to import all data from Server/Instance "Server Foo", Database "Foo" and table "Foo", into destination Server/Instance "Server Goo", Database "Goo" and table "Goo". Table Foo and Table Goo are of the same schema. If the same row exists for table Goo, I want to keep the origin data in Goo and ingore the import row in Foo (table Foo and table Goo both has a uniqueidentifier type column called CustomerID which acts as primary key and clustered index), just like ignore duplicate key does.

我正在寻找简单可靠的方法来编写 T-SQL 来解决数据导出/导入问题.有参考样本吗?

merge into [dbo].[Orders] as Target
using "LabTest1\SQLServer2008.OrderDB.dbo.Orders" as source
on target.Hash = source.Hash
when not matched then
INSERT     ([Hash]
           ,[Order]
           ,[Name]
           ,[CreationTime]
           ,[Description])
     VALUES
     (
     source.[Hash], source.[Order], source.[Name], source.[CreationTime], source.[Description]
     )
when MATCHED then
;

MERGE 
  INTO Goo.Goo as Target
  USING Foo.Foo.dbo.Foo as Source
  ON Source.ID = Target.ID
WHEN NOT MATCHED THEN
  INSERT (field1, field2, field3)
  VALUES (source.field1, source.field2, source.field3)  
WHEN MATCHED THEN
  -- do nothing
;
