经常遇到此类情况：后台误操作，不小心删除后台 discuz 代码，导致找不到 discuz 代码设置或者论坛的 discuz 代码无法正常使用；

下面主要讲述Discuz7.0.0版本遇到此类情况的一个解决方法，这里以常用的 Flash 为例；

论坛后台 => 工具 => 数据库 => 升级：

CODE: [COPY]
• INSERT INTO cdb_bbcodes VALUES ('21','0','0','flash','bb_flash.gif','<object classid=\"clsid:d27cdb6e-ae6d-11cf-96b8-444553540000\" codebase=\"http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0\" width=\"550\" height=\"400\"><param name=\"allowScriptAccess\" value=\"sameDomain\"><param name=\"movie\" value=\"{1}\"><param name=\"quality\" value=\"high\"><param name=\"bgcolor\" value=\"#ffffff\"><embed src=\"{1}\" quality=\"high\" bgcolor=\"#ffffff\" width=\"550\" height=\"400\" allowScriptAccess=\"sameDomain\" type=\"application/x-shockwave-flash\" pluginspage=\"http://www.macromedia.com/go/getflashplayer\" wmode=\"transparent\" /></object>','Flash Movie','嵌入 Flash 动画','1','请输入 Flash 动画的 URL:','1','20');

复制上面的代码执行下，执行后，不小心删除的 Flash 代码就可以正常看到了。

其他的 discuz 代码都可以在论坛的 install 目录下 discuz.sql 文件内看到对应的 SQL 语句。

其他的 discuz 代码的 SQL 语句内容如下：
