备份数据到Excel概述1

数据库，简而言之可视为电子化的文件柜——存储电子文件的处所，用户可以对文件中的数据进行新增、截取、更新、删除等操作。所谓“数据库”是以一定方式储存在一起、能与多个用户共享、具有尽可能小的冗余度、与应用程序彼此独立的数据集合。

This stored procedure can be used to insert the result set of the
particular select statement into Excel file (c:\ImportToExcel.xls,
by default).
You can pass the server name, user name, user password, the select
statement to execute, and the file name to store the results set,
as in the example below:

EXEC ExportToExcel @server = '.',
                   @uname = 'sa',
                   @QueryText = 'SELECT au_fname FROM pubs..authors',
                   @filename = 'c:\ImportToExcel.xls'
