我想在数据库之间自动传输数据。例如，每隔一小时，第一个数据库中的一个表中的数据将被复制到第二个数据库中的一个表中。

你建议我做什么？也许通过使用工作？

提前致谢。

You can probably look at SQL Server Database Mirroring if you are already on SQL Server 2008. Avoids the need for an additional ETL tool.

Create a store procedure and schedule it for one hours:-

Create procedure copydata
AS
INSERT INTO DB1.dbo.TempTable
SELECT * FROM DB2.dbo.TempTable

这里是“穷人的方法”。

此逻辑将消除每次截断目标表的需要。

您可以安排一个作业每小时调用一次存储过程。

OrganizationDB，这是我的数据库名称。你的可能不一样。

如果您的源数据位于不同的数据库中，请使用该数据库的名称 ....

USE [OrganizationDB]

DROP TABLE [dbo].[EmployeeSource]

您是否考虑过使用集成服务？
您可以设置一个包做您想做的事情，然后使用调度程序将其添加到作业中。

如果这只是一个表中的数据，并且两个数据库都在同一台服务器上，您还可以考虑在该表上创建 INSERT 触发器，该触发器将自动捕获所有新数据并将其复制到辅助数据库中。

如果数据库不在同一台服务器上并且服务器不在同一物理位置，我不会这样做，因为它可能会导致性能问题。
