万博app体育游戏注册:power designer逆向工程生成PDM时的列注释(ColumnComment)解决方案



在用powerdesigner逆向工程天生PDM时,列注释(ColumnComment)始终无法天生,历经数小时的探索,找到一个协调的措施,现分享如下。并盼望有高手辅导更好的措施。

邀月应用的是Powerdesigner 15.2,数据库为SQL Server 2008 r2

措施如下:

1、在PowerDesigner界面万博app体育游戏注册-File-Reverse E万博app体育游戏注册ngineer-Database,然后选择一个DBMS,我这里拔取一个由系统默认的SQL Server 2008 DBMS改动而来的SQL_2008_MyDefine。

选好odbc,输入精确的连接串,选择数据库及表。

天生效果:Name为英文,且Comment列为空。

而我们盼望的是Name列为中文,Comment为中文。

查看了下在线赞助,发明在SQL_2008_MyDefine::Script\Objects\Column\SqlListQuery下的Value值如下:

{OWNER, TABLE, S, COLUMN, DTTPCODE, LENGTH, SIZE, PREC, COMPUTE, NOTNULL, IDENTITY, DOMAIN, DEFAULT, ExtIdentitySeedInc, COMMENT, ExtCollation, ExtIdtNotForReplication, ExtDeftConstName, Sparse, FileStream, ExtRow万博app体育游戏注册GuidCol}

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_idc.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,

(select convert(varchar(8000), value) from ::fn_listextendedproperty(NULL, 'user', u.name, 'table', o.name, 'column', c.name) where name = 'MS_Description') as colnE,

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)

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.d万博app体育游戏注册efault万博app体育游戏注册_object_id)

where

o.type in ('U', 'S', 'V')

[ and u.name = %.q:OWNER%]

[ and o.name=%.q:TABLE%]
