PowerDesigner 15進行逆向工程生成數據庫圖表時，註釋的comment的生成，解決PowerDesigner逆向工程沒有列註釋

使用PowerDesigner默認配置逆向工程是沒有註釋（name列爲英文，comment列是空的），這樣的不方便查看字段具體是什麼意義，將註釋一同導出，方便查看字段具體的意義，如下圖

 

 註釋列導出步驟

1、新建腳本DBMS，選擇菜單：Tools→Resources→DBMS

彈出List Of DBMS對話框，選擇新建

彈出新建對話框，填寫名稱爲“My Microsoft SQL Server 2008”（這個名稱可以自己定義），選擇“Microsoft SQL Server 2008”，點擊OK

 

上圖默認文件，不需要修改，直接點保存，彈出下圖

 點擊展開script->objects->column，選中SqlListQuery，如下圖

 

將下面的腳本複製到右邊的Value輸入框中覆蓋原來的腳本，點擊確定

{OWNER, TABLE, S, COLUMN, DTTPCODE, LENGTH, SIZE, PREC, COMPUTE, NOTNULL, IDENTITY, DOMAIN, DEFAULT, ExtIdentitySeedInc,COMMENT,COLNNAME, ExtCollation, ExtIdtNotForReplication, ExtDeftConstName, Sparse, FileStream, ExtRowGuidCol}

select
    u.name,
    o.name,
    c.column_id,
    c.name,
    case when c.system_type_id in (165, 167, 231) and c.max_length = -1 then t.name + '(Max)' else t.name end,
    c.precision,
    case (c.max_length) when -1 then 0 else case when c.system_type_id in (99, 231, 239) then (c.max_length/2) else (c.max_length) end end as colnA,
    c.scale,
    case(c.is_computed) when 1 then convert(varchar(8000), (select z.definition from [%CATALOG%.]sys.computed_columns z where z.object_id = c.object_id and z.column_id = c.column_id)) else '' end as colnB,
    case(c.is_nullable) when 1 then 'NULL' else 'NOTNULL' end,
    case(c.is_identity) when 1 then 'identity' else '' end,
    case when(c.user_type_id <> c.system_type_id) then (select d.name from [%CATALOG%.]sys.types d where d.user_type_id = c.user_type_id) else '' end as colnC,
    convert(varchar(8000), d.definition),
    case (c.is_identity) when 1 then convert(varchar, i.seed_value) + ', ' + convert(varchar, i.increment_value) else '' end as colnD,
    convert(varchar(8000), e.value) as colnE,
    convert(varchar(8000), e.value) as colnF,
    c.collation_name,
    case (i.is_not_for_replication) when 1 then 'true' else 'false' end,
    d.name,
    case(c.is_sparse) when 1 then 'true' else 'false' end,
    case(c.is_filestream) when 1 then 'true' else 'false' end,
    case(c.is_rowguidcol) when 1 then 'true' else 'false' end
from
    [%CATALOG%.]sys.columns      c
    join [%CATALOG%.]sys.objects o on (o.object_id = c.object_id)
    join [%CATALOG%.]sys.schemas u on (u.schema_id = o.schema_id)
    join [%CATALOG%.]sys.types   t on (t.user_type_id = c.system_type_id)
    left outer join [%CATALOG%.]sys.identity_columns i on (i.object_id = c.object_id and i.column_id = c.column_id)
    left outer join [%CATALOG%.]sys.default_constraints d on (d.object_id = c.default_object_id)
    left outer join [%CATALOG%.]sys.extended_properties e on (e.class=u.schema_id and e.major_id=o.object_id and e.minor_id = c.column_id and e.name=N'MS_Description')
where 
   o.type in ('U', 'S', 'V')
[  and u.name = %.q:OWNER%]
[  and o.name=%.q:TABLE%]
order by 1, 2, 3

選擇File→Reverse Engineer→Database 對數據庫進行逆向工程，DBMS選擇剛纔新建的“My Microsoft SQL Server 2008”，點擊確定

選擇使用剛纔新建的“My Microsoft SQL Server 2008”

選項按照下圖選中的，點擊確定

到此修改配置完成，下面開始生產逆向工程

按照下圖步驟操作

 

 

點擊確定

選擇數據庫點擊OK

 

點擊OK就可以生產註釋的逆向工程

上面步驟數據庫表的註釋comment沒有導出來，下面導出數據庫表註釋comment

選擇菜單：工具→Execute Commands→Edit/Run Script，Run運行vbs腳本即可。

將下面的腳本複製到上圖的輸入框中，點擊run，就可生成表的comment註釋了

'把pd中那麼name想自動添加到comment裏面
'如果comment爲空,則填入name;如果不爲空,則保留不變,這樣可以避免已有的註釋丟失.
 
Option Explicit 
ValidationMode = True
InteractiveMode = im_Batch 
 
Dim mdl ' the current model 
 
' get the current active model 
Set mdl = ActiveModel 
If (mdl Is Nothing) Then
 MsgBox "There is no current Model "
ElseIf Not mdl.IsKindOf(PdPDM.cls_Model) Then
 MsgBox "The current model is not an Physical Data model. "
Else
 ProcessFolder mdl 
End If
 
' This routine copy name into comment for each table, each column and each view 
' of the current folder 
Private sub ProcessFolder(folder)  
 Dim Tab 'running   table  
 for each Tab in folder.tables  
  if not tab.isShortcut then 
    if trim(tab.comment)="" then '如果有表的註釋,則不改變它.如果沒有表註釋.則把name添加到註釋裏面. 
       tab.comment = tab.name 
    end if  
 Dim col ' running column  
 for each col in tab.columns 
  if trim(col.comment)="" then '如果col的comment爲空,則填入name,如果已有註釋,則不添加;這樣可以避免已有註釋丟失.
   col.comment= col.name 
  end if 
 next  
  end if  
 next  
   
 Dim view 'running view  
 for each view in folder.Views  
  if not view.isShortcut and trim(view.comment)=""  then  
 view.comment = view.name  
  end if  
 next  
   
 ' go into the sub-packages  
 Dim f ' running folder  
 For Each f In folder.Packages  
  if not f.IsShortcut then  
 ProcessFolder f  
  end if  
 Next 
end sub

點擊run，導出的表註釋效果如下
