開發一個項目時都會有一個蛋疼的問題——寫資料庫需求文檔，然後根據這個文檔來建資料庫，如果後來需求改了，要改資料庫還要改文檔，有時忙著忙著就忘改了，導致文檔是過期的。那麼我們自己寫個腳本在資料庫運行直接生產數據字典，這樣只要改資料庫就行了。目前在網上搜了下，發現sqlServer只有2005的生成工具 ...
開發一個項目時都會有一個蛋疼的問題——寫資料庫需求文檔，然後根據這個文檔來建資料庫，如果後來需求改了，要改資料庫還要改文檔，有時忙著忙著就忘改了，導致文檔是過期的。那麼我們自己寫個腳本在資料庫運行直接生產數據字典，這樣只要改資料庫就行了。目前在網上搜了下，發現sqlServer只有2005的生成工具，沒有08的，存儲過程倒是有，不過下載運行一遍到處是坑，寫的也太差了，於是對腳本進行改進。
