在PowerDesigner 16 中生成的sql語句,在執行的時候報錯:對象名sysproperties 無效的錯誤;造成此問題的原因是由于Sql 2005、2008 刪除了系統表 sysproperties 而改用 sys.extended_properties 表所致 ， 以下是通過創建sysproperties視圖，以及修改powerdesigner sql語句生成模板后，

再生成數據庫SQL腳本執行,共分為三部:

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

if exists (select 1 from sysobjects where name = 'sysproperties'and xtype = 'V') beginDROP VIEW sysproperties endGOCREATE VIEW syspropertiesASSELECT 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 PropValueFROM sysobjects As A INNER JOIN syscolumns As B ON A.id = B.idINNER JOIN sys.extended_properties As C ON C.major_id = A.id AND ( minor_id = B.colid)

第二 步: 修改Table TableComment模板 路徑是 Database -> Edit Current DBMS 窗體 General 選項卡 下 Script -> Objects -> Table -> TableComment

按 Ctrl+C 復制代碼 [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 路徑是 Database -> Edit Current DBMS 窗體 General 選項卡 下 Script -> Objects -> Column -> ColumnComment 按 Ctrl+C 復制代碼 [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下執行 不在報找不到sysproperties 的錯誤。
