<p>对于sql server的delete操作,其实本质也是类似oracle的,我们可以通过两种途径进行恢复:1.直接解析sql的日志,2.直接读取mdf/ndf文件找出来被标记为删除的记录,在有日志的情况下,通过日志分析能够更加准确的定位记录(因为根据删除标记可能找到的记录不是这次删除操作的),这里来一个简单的恢复过程,一张sql server的表,记录数为83条<br />

<hr />
对其进行delete删除操作<br />
<a href="//www.xifenfei.com/wp-content/uploads/2019/11/20191119114955.png"><img src="//www.xifenfei.com/wp-content/uploads/2019/11/20191119114955.png" alt="20191119114955" width="567" height="200" class="alignnone size-full wp-image-8277" /></a><br />
<hr />
进行恢复分析,直接生成insert语句,反插入库即可<br />
<a href="//www.xifenfei.com/wp-content/uploads/2019/11/20191119115219.png"><img src="//www.xifenfei.com/wp-content/uploads/2019/11/20191119115219.png" alt="20191119115219" width="1341" height="301" class="alignnone size-full wp-image-8278" /></a><br />

<a href="//www.xifenfei.com/wp-content/uploads/2019/11/20191119120132.png"><img src="//www.xifenfei.com/wp-content/uploads/2019/11/20191119120132.png" alt="20191119120132" width="1470" height="904" class="alignnone size-full wp-image-8279" /></a><br />
<hr />
同时我们还可以根据需要生成对应的redo/undo相关sql语句<br />
