设置链接服务器，然后在目标数据库上使用以下内容：
INSERT INTO existingTable (col1,col2..)
SELECT col1,col2...
FROM linkedserver.dbo.database.othertable

使用 SQL Server 导入和导出向导。这可能是完成此任务的最简单方法。
对于更高级的数据传输，请考虑使用bcp实用程序、BULK INSERT语句和OPENDATASOURCE.

我会使用数据转换服务（又名集成服务）。

这是我喜欢使用的脚本。易于使用，并且几乎没有错误。只需将下面的文本复制到您的查询窗口中，然后按照说明进行操作。运行它之后，您将拥有一堆可以在另一台服务器上运行的插入语句。
/*
Use this script to create insert statements for each row in the specified table.
Instructions:
1. Set the database you want to script from as normal.
2. change the set @TableName = '<YourTableName>' line to be the
table you want to script out.
3. Run the script and copy all the text from the results below
the line with all the dashes (----).
Notes:
If you get the error message "Invalid object name '<YourTableName>'."
then you either forgot to set the correct database or you spelled
your table name wrong

取决于数据传输的数量和频率。这是一个小批量的一次性过程，您最好使用 T-SQL 直接插入数据。这可以通过链接服务器或 OPENQUERY 子句来完成。
如果它的一次性处理量很大，请使用 SSIS 或 BCP 实用程序。
如果它的高容量高频率，使用复制。
