數據庫，簡而言之可視為電子化的文件柜——存儲電子文件的處所，用戶可以對文件中的數據進行新增、截取、更新、刪除等操作。所謂“數據庫”是以一定方式儲存在一起、能與多個用戶共享、具有盡可能小的冗余度、與應用程序彼此獨立的數據集合。
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'
