解决PowerDesigner 16 for SqlServer2008 syspropert...

在PowerDesigner 16 中生成的sql语句,在执行的时候报错:对象名sysproperties 无效的错误;造成此问题的原因是由于Sql 2005、2008 删除了系统表 sysproperties 而改用 sys.extended_properties 表所致 ， 以下是通过创建sysproperties视图，以及修改powerdesigner sql语句生成模板后，

再生成数据库SQL脚本执行,共分为三部:

第一步:在Sql 2005/2008 Exec the Sql 创建View 'sysproperties'

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)
--WHERE A.name = 'T_WebUser'
GO

 

第二 步: 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 and name = 'MS_Description') 
begin 
   [%OWNER%?[.O:[execute ][exec ]]sp_dropextendedproperty [%R%?[N]]'MS_Description', 
   [%R%?[N]]'user', [%R%?[N]]%.q:OWNER%, [%R%?[N]]'table', [%R%?[N]]%.q:TABLE% 
:declare @CurrentUser sysname 
select @CurrentUser = user_name() 
[.O:[execute ][exec ]]sp_dropextendedproperty [%R%?[N]]'MS_Description',  
   [%R%?[N]]'user', [%R%?[N]]@CurrentUser, [%R%?[N]]'table', [%R%?[N]]%.q:TABLE% 
] 
end 

][%OWNER%?[.O:[execute ][exec ]]sp_addextendedproperty [%R%?[N]]'MS_Description', 
   [%R%?[N]]%.q:COMMENT%, 
   [%R%?[N]]'user', [%R%?[N]]%.q:OWNER%, [%R%?[N]]'table', [%R%?[N]]%.q:TABLE% 
:select @CurrentUser = user_name() 
[.O:[execute ][exec ]]sp_addextendedproperty [%R%?[N]]'MS_Description',  
   [%R%?[N]]%.q:COMMENT%, 
   [%R%?[N]]'user', [%R%?[N]]@CurrentUser, [%R%?[N]]'table', [%R%?[N]]%.q:TABLE% 
]

 

第三步: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 sysproperties 
where TableID = object_id('[%QUALIFIER%]%TABLE%') 
and ColName = %.q:COLUMN% AND PropName='MS_Description') 
begin 
[%OWNER%?[.O:[execute ][exec ]]sp_dropextendedproperty [%R%?[N]]'MS_Description', 
[%R%?[N]]'user', [%R%?[N]]%.q:OWNER%, [%R%?[N]]'table', [%R%?[N]]%.q:TABLE%, [%R%?[N]]'column', [%R%?[N]]%.q:COLUMN% 
:declare @CurrentUser sysname 
select @CurrentUser = user_name() 
[.O:[execute ][exec ]]sp_dropextendedproperty [%R%?[N]]'MS_Description',  
[%R%?[N]]'user', [%R%?[N]]@CurrentUser, [%R%?[N]]'table', [%R%?[N]]%.q:TABLE%, [%R%?[N]]'column', [%R%?[N]]%.q:COLUMN% 
] 


end 


][%OWNER%?[.O:[execute ][exec ]]sp_addextendedproperty [%R%?[N]]'MS_Description', 
[%R%?[N]]%.q:COMMENT%, 
[%R%?[N]]'user', [%R%?[N]]%.q:OWNER%, [%R%?[N]]'table', [%R%?[N]]%.q:TABLE%, [%R%?[N]]'column', [%R%?[N]]%.q:COLUMN% 
:select @CurrentUser = user_name() 
[.O:[execute ][exec ]]sp_addextendedproperty [%R%?[N]]'MS_Description',  
[%R%?[N]]%.q:COMMENT%, 
[%R%?[N]]'user', [%R%?[N]]@CurrentUser, [%R%?[N]]'table', [%R%?[N]]%.q:TABLE%, [%R%?[N]]'column', [%R%?[N]]%.q:COLUMN% 
] 

 

修改之后 使用Generate Database 生成的SQL便可在SQL 2005/2008下执行 不在报找不到sysproperties 的错误。
