PD16 Generate Datebase For Sql2008R2时报脚本错误“对象名sysproperties无效”

PowerDesinger16创建数据库表到SQL2008R2时，执行报“对象名sysproperties无效”错误。

主要是在建模时我们对表、列增加了些说明注释，而Sql2005之后系统表sysproperties已废弃删除而改用sys.extended_properties所致。

此问题解决主要参考了http://hi.baidu.com/xuefliang/item/45e7f71421d5a67871d5e8e2，

1、修改Table TableComment模板

路径是 Database -> Edit Current DBMS 窗体 General 选项卡 下 Script -> Objects -> Table –> TableComment

[if exists (select 1
            from  sys.extended_properties
            where  major_id = object_id('[%QUALIFIER%]%TABLE%')
            and   minor_id = 0 )
/* SQL2008 属性表sysproperties改为 sys.extended_properties代替，替换以下脚本
[if exists (select 1
            from  sysproperties
           where  id = object_id('[%QUALIFIER%]%TABLE%')
            and   type = 3)
*/

2、修改Column ColumnComment模板

路径是 Database -> Edit Current DBMS 窗体 General 选项卡 下 Script -> Objects -> Column –> ColumnComment

[if exists (select 1
            from  sys.extended_properties
            where  major_id = object_id('[%QUALIFIER%]%TABLE%')
            and   minor_id <> 0 and name = 'MS_Description')
/* SQL2008 属性表sysproperties改为 sys.extended_properties代替，替换以下脚本
if exists (select 1
            from  sysproperties
           where  id = object_id('[%QUALIFIER%]%TABLE%')
            and   type = 4)
*/

也可创建sysproperties视图来，通过此视图处理以上问题。

 if exists (select 1
              from  sysobjects
             where  name = 'sysproperties'
              and   xtype = 'V')
  begin
   DROP VIEW sysproperties
  end
  GO  
 
  CREATE VIEW sysproperties
  AS
  SELECT A.name As TableName,A.id As TableID,B.Name As ColName,B.colid As ColID,B.xtype As ColType,C.name As PropName,C.Value As PropValue
  FROM sysobjects As A
  INNER JOIN syscolumns As B ON A.id = B.id
  INNER JOIN sys.extended_properties As C ON C.major_id = A.id AND ( minor_id = B.colid)
