sql server 新增表註釋、欄位註釋

--為欄位添加註釋  --格式如右:execute sp_addextendedproperty 'MS_Description','欄位備註資訊','user','dbo','table','欄位所屬的表名','column','添加註釋的欄位名'; execute sp_addextendedproperty 'MS_Description','add by liyc. 診斷類別碼','user','dbo','table','DiagRecord','column','DiagTypeCode';   --修改欄位註釋  execute sp_updateextendedproperty 'MS_Description','add by liyc.','user','dbo','table','DiagRecord','column','DiagTypeCode';
  --刪除欄位註釋 execute sp_dropextendedproperty 'MS_Description','user','dbo','table','DiagRecord','column','DiagTypeCode';   -- 新增表註釋 execute sp_addextendedproperty 'MS_Description','診斷記錄檔案','user','dbo','table','DiagRecord',null,null;   -- 修改表註釋 execute sp_updateextendedproperty 'MS_Description','診斷記錄檔案1','user','dbo','table','DiagRecord',null,null;
  -- 刪除表註釋 execute sp_dropextendedproperty 'MS_Description','user','dbo','table','DiagRecord',null,null;   -- 說明: -- 1.增加、修改、刪除註釋呼叫不同的儲存過程   -- 2.增加、修改註釋呼叫的儲存過程引數數量和含義相同,刪除備註比前兩者少了一個“備註內容”的引數 -- 3.為表添加註釋相比於為欄位添加註釋,最後兩個引數為null    --查看錶的註釋
