增量备份恢复
增量备份以后如何用SQL语言恢复数据,谢谢

------解决方案--------------------
本来我这儿有现成的作业，可以导出脚本，不过因为
增量备份的作业中包含代码go，所以导出来的脚本不能直接使用
只好把增量备份那一段给你COPY出来了。
增量备份代码
backup database dev to disk =N 'D:\BACKUP\kimi\diff\diffbak1.bak ',
DISK =N 'D:\BACKUP\kimi\diff\diffbak2.bak ',
DISK =N 'D:\BACKUP\kimi\diff\diffbak3.bak ',
DISK =N 'D:\BACKUP\kimi\diff\diffbak4.bak ',
DISK =N 'D:\BACKUP\kimi\diff\diffbak5.bak ',
DISK =N 'D:\BACKUP\kimi\diff\diffbak6.bak ',
DISK =N 'D:\BACKUP\kimi\diff\diffbak7.bak ',
DISK =N 'D:\BACKUP\kimi\diff\diffbak8.bak ',
DISK =N 'D:\BACKUP\kimi\diff\diffbak9.bak ',
DISK =N 'D:\BACKUP\kimi\diff\diffbak10.bak '
with DIFFERENTIAL

恢复代码，作业导出的脚本，拿过去执行一下就可以生成作业
然后自己可以在作业里面改的。
