团队合作设计一套系统数据模型,创建了PDM后,Table、View、Store Procedure等都创建好了,且创建了多个Schema方便管理这些数据库对象,但Table、view、Column等对象有Comment时(用来在团队不同成员间共享描述信息)
生成数据库时会得到一个提示"不支持扩展属性,或对象不存在",分析发现异常在类似以下语句:
if exists(select 1 from sys.extended_properties p where p.major_id = object_id('Environment.Resource') and p.minor_id = (select c.column_id from sys.columns c where c.object_id = p.major_id and c.name = 'ResourceCode') ) begin execute sp_dropextendedproperty 'MS_Description', 'user', 'Environment', 'table', 'Resource', 'column', 'ResourceCode' end execute sp_addextendedproperty 'MS_Description', '资源编码', 'user', 'Environment', 'table', 'Resource', 'column', 'ResourceCode' go
分析原因,发现是由于采用了Schema(上述代码中的Environment),所以sp_addextendedproperty存储过程的第三个参数就应该是SCHEMA而不是user。查询相关资料发现以上SQL语句是基于Powerdesigner自带的对应的.xdb文件生成的,如下图是Column注释信息的SQL代码模板,对应的xdb模板文件存放在powerdesigner安装路径的Sybase\PowerDesigner 16\Resource Files\DBMS\sqlsv2012.xdb
如上图,每个Column的Comment信息均通过以上代码模板生成,所以只需要修改代码模板(将sp_addextendedproperty的第三个参数值由user修改为schema即可)即可让所有对象的Comment生成语句得到修正。
注:在win7以上系统中需要使用管理员权限运行powerdesigner才能将修改后的模板文件保存。

补充:
ColumnContent修改为:
Value修改为:
[if exists (select 1 from sys.extended_properties where major_id = object_id('[%QUALIFIER%]%TABLE%') and minor_id = 0) begin [%OWNER%?[.O:[execute ][exec ]]sp_dropextendedproperty [%R%?[N]]'MS_Description', [%R%?[N]]'schema', [%R%?[N]]%.q:OWNER%, [%R%?[N]]'table', [%R%?[N]]%.q:TABLE% :declare @CurrentUser sysname select @CurrentUser = SCHEMA_NAME() [.O:[execute ][exec ]]sp_dropextendedproperty [%R%?[N]]'MS_Description', [%R%?[N]]'schema', [%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]]'schema', [%R%?[N]]%.q:OWNER%, [%R%?[N]]'table', [%R%?[N]]%.q:TABLE% :select @CurrentUser = SCHEMA_NAME() [.O:[execute ][exec ]]sp_addextendedproperty [%R%?[N]]'MS_Description', [%R%?[N]]%.q:COMMENT%, [%R%?[N]]'schema', [%R%?[N]]@CurrentUser, [%R%?[N]]'table', [%R%?[N]]%.q:TABLE% ]
Values修改为:

这个是表的
其他类型同理,主要修改Values值中的user为schema,和select @CurrentUser = User_NAME() 修改为 select @CurrentUser = SCHEMA_NAME()
