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. The Transact-SQL statements, we mainly use OpenDataSource function, OPENROWSET function, the function of the details, please

Excel表格是输入输出经常需要涉及到的。操作Excel表格的方式也多种多样。比如,通过调用Excel程序的COM组件对Excel进行操作。但是,这种方式限制较多,且实现难度比较大。但是,用于访问数据库的组件ADO,是支持多种数据源的,其中就包括Excel文件。我们可以通过ADO组件对Excel文件进行读写访问。当然,在.NET平台上对应ADO数据访问组件的是ADO.NET组件。我编写的这个类就是通过ADO.NET实现了Excel文件的读写。由于时间仓促,功能还不是很完善,会在以后有时间的时候进行版本升级。也请各位高手多多批评指正。
-Excel spreadsheet input and output is often of the need to address. Operation Excel variety of ways. For example, by calling the Excel COM procedures for the operation of Excel. However, this approach is more limited and more difficult to achieve. However, for access to the database components ADO, is to support multiple data sources, including Excel file. We can ADO components to read and write Excel files visit. Of course,.NET platform counterparts ADO data access components of ADO.NET components. I prepared this category is achieved through ADO.NET read and write Excel files. Because time is so short, the function is still not perfect, will in future have the time for version upgrades.
