数据库应用，在许多软件系统中经常用到，是开发中大型系统不可缺少的辅助。但如果对数据库资源没有很好地管理(如：没有及时回收数据库的游标(ResultSet)、Statement、连接 (Connection)等资源)，往往会直接导致系统的稳定。这类不稳定因素，不单单由数据库或者系统本身一方引起，只有系统正式使用后，随着流量、用户的增加，才会逐步显露。 -database applications, in many software systems often used, is developing large systems indispensable aids. But if the right database resources are not well managed (eg : no timely recovery database cursor (ResultSet), the Statement connect (Connection), and other resources), will often lead directly to the stability of this system. Such factors of instability, not only by the database system itself or caused side, the official use only, as the flow of users increases, will gradually revealed.

This a p熟悉SQL SERVER 2000的数据库管理员都知道，其DTS可以进行数据的导入导出，其实，我们也可以使用Transact-SQL语句进行导入导出操作。在 Transact-SQL语句中，我们主要使用OpenDataSource函数、OPENROWSET 函数，关于函数的详细说明，请参考SQL联机帮助。利用下述方法，可以十分容易地实现SQL SERVER、ACCESS、EXCEL数据转换，hoto of a general purpose timer/counter card you can wirewrap in a weekend. It plugs into your PC s ISA bus just like a sound or modem card. It gives high-resolution timing (microseconds). Because of its programmablity, it is very powerful and flexible. You can even control DC or servo motors using pulse-width modulated (PWM), or stepper motors using its square wave capabilities. The figure below is the actual output (square wave) from the 8254 card captured by an oscilloscope: -This a p familiar with the SQL Server 2000 database administrators know, the DTS can import data is derived, in fact, we can also use Transact-SQL for importing and exporting operation.
