MS SQL生成数据库字典脚本
2024-08-25 01:40:24
开发一个项目时都会有一个蛋疼的问题——写数据库需求文档，然后根据这个文档来建数据库，如果后来需求改了，要改数据库还要改文档，有时忙着忙着就忘改了，导致文档是过期的。那么我们自己写个脚本在数据库运行直接生产数据字典，这样只要改数据库就行了。目前在网上搜了下，发现sqlServer只有2005的生成工具，没有08的，存储过程倒是有，不过下载运行一遍到处是坑，写的也太差了，于是对脚本进行改进。

注意事项：
1、以上脚本直接在SQL SERVER运行，以文本格式显示，设置如下：
红框的不要勾选
2、如果要加注释，表的注释在这里加
字段的注释：
3、生成后保存为HTML文件即可
