可以改为osql.exe,这个的通用性好一些.

但这样必须指定服务器名.

当然,要求至少有sql服务(不管是否在本机)

安装sql客户端

教你如何使用Firebird的命令行工具来执行一个文件脚本。

sqlserver2000 数据库用户数据库自动备份和日志自动清理说明： (本脚本主要实现yymis数据库自动备份和日志自动清理的功能) 本脚本包含三个文件： 1.sqlserverbackup.bat 任务执行的批处理文件 2.sqlserverbackup.sql 批处理文件调用的sql脚本文件 3.Readme.txt 功能说明文件说明： 1.建立一个数据备份的文件夹，把sqlserverbackup.bat 和 sqlserverbackup.sql 文件拷到该文件夹目录下,如：d:\backup\sqlserverbackup.bat 和 d:\backup\serverbackup.sql ; 2.修改脚本文件， (1)、在sqlserverbackup.bat 中修改isql 的登陆用户和密码，以及输入、输出文件路径如：isql -Usa -P -i d:\backup\sqlserver.bat -o d:\backup\sqlserver.out 注：用户必须用系统管理员或数据库的dbo用户 (2)、在sqlserverbackup.sql 中修改 @dumpfile 的路径值如：select @dumpfile = 'd:\backup\sql_yymis.bak' + datename(dw,getdate()) 2.打开“控制面板”-->“任务计划”添加一个任务，让其每天定时执行sqlserverbackup.bat脚本； 3.备份的文件保留一个星期，备份的数据文件名有星期几表示如：“sql_yymis.bak星期一”，第二个星期开始后覆盖； 4.脚本运行后会产生一个输出文件：sqlserverbackup.out，记录脚本的执行情况。
