oracle 数据查询sql
我现在有一张表A 我现在向把表A中的数据放到表B中 create table B as select (需要查询A表中需要的字段) ftom A where (); 问题是 我表A中有contentpicsyn字段中存放的是<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0" width="480" height="360"><param name="movie" value="/module/media/videotool/vcastr22.swf"><param name="quality" value="high"><param name="menu" value="false"><param name="allowFullScreen" value="true" /><param name="FlashVars" value="vcastr_file=http://video.chncpa.org/video/1384483546789.flv&vcastr_title="><param name="wmode" value="opaque" /><embed src="/module/media/videotool/vcastr22.swf" allowFullScreen="true" FlashVars="vcastr_file=http://video.chncpa.org/video/1384483546789.flv&vcastr_title=" menu="false" quality="high" width="480" height="360" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" /></object> 和
<object id="MediaPlayer1" width="350" height="64" classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=6,4,7,1112" align="baseline" border="0" standby="Loading Microsoft Windows Media Player components..." type="application/x-oleobject"><param name="URL" value="http://video.chncpa.org/audio/1385630913790.wma"><param name="autoStart" value="true"><param name="invokeURLs" value="false"><param name="playCount" value="100"><param name="defaultFrame" value="datawindow"><embed src="http://video.chncpa.org/audio/1385630913790.wma" align="baseline" border="0" width="350" height="68"type="application/x-mplayer2"pluginspage=""name="MediaPlayer1" showcontrols="1" showpositioncontrols="0"showaudiocontrols="1" showtracker="1" showdisplay="0"showstatusbar="1"autosize="0"showgotobar="0" showcaptioning="0" autostart="1" autorewind="0"animationatstart="0" transparentatstart="0" allowscan="1"enablecontextmenu="1" clicktoplay="0"defaultframe="datawindow" invokeurls="0"></embed></object>两种一种视频和一种音频的代码
现在我想把表A中这个字段这两个文件的路径提取出来放到表B中(注:两段代码并不是在一起而是比如第一调试数据中这个字段存的是音频代码第二条是视频代码) 提取之后的结构例如: 1 字段1 字段2 字段三 音频路径
2 字段1 字段2 字段3 视频路径 该如何处理这个提取音频视频的sql 求指教!!!
