 三、生成后保存为HTML文件就可以

  一、以上脚本直接在SQL SE君越VE逍客运维,以文本格式呈现,设置如下:

     二、假设要加注释,表的笺注在此间加

  红框的不要勾选

  开辟1个体系时都会有多少个蛋疼的主题素材——写数据库需求文档,然后根据这么些文档来建数据库,假设后来须要改了,要改数据库还要改文书档案,有时忙着忙着就忘改了,导致文书档案是过期的。那么大家和谐写个脚本在数据库运营直接生产数据字典,那样只要改数据库就行了。近日在英特网搜了下,发掘sqlServer只有2006的变动工具,未有0捌的,存款和储蓄进程倒是有,然而下载运维三次街头巷尾是坑,写的也太差了,于是对台本进行创新。

 字段的注解:
