将下面的内容保存为sqlreboot.bat,然后添加到计划任务里，就可以实现一段时间后重启sqlserver服务器了，防止sqlserver经常占用内存过高，导致网页无法打开数据。
net stop sqlserveragent
net stop mssqlserver
echo.wscript.sleep(50000)>s.vbs
cscript //nologo s.vbs
del s.vbs
net start mssqlserver
net start sqlserveragent
收缩sqlserver数据库，清空日志文件
DUMP TRANSACTION [数据库名] WITH NO_LOG
BACKUP LOG [数据库名] WITH NO_LOG
DBCC SHRINKDATABASE([数据库名])
