我是靠谱客的博主清秀翅膀，最近开发中收集的这篇文章主要介绍PowerDesigner16生成SQL2005列注释的方法，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

Powerdesigner界面－tools-Resources－DBMS,点击左上角的New,选择copy from templete,如果你的数据库是sql server 2005,选择系统自带的SQL server 2005，如果是sql server 2008,选择系统自带的sqlsv2k8.xdb。

如果你想修改默认的选项，可以直接选择SQL server 2005或者08.

选择Script---Objects---Column---SqlListQuery

修改为如下的代码：

复制代码代码如下:

{OWNER, TABLE, S, COLUMN, DTTPCODE, LENGTH, SIZE, PREC, COMPUTE, NOTNULL, IDENTITY, DOMAIN, DEFAULT, ExtIdentitySeedInc, COMMENT,COLNNAME, ExtCollation, ExtIdtNotForReplication, ExtDeftConstName, ExtRowGuidCol}

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_id <> c.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,
    convert(varchar(8000), p.value),
    convert(varchar(8000), p.value),
    c.collation_name,
    case (i.is_not_for_replication) when 1 then 'true' else 'false' end,
    d.name,
    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)
    join [%CATALOG%.]sys.types   t on (t.user_type_id = c.system_type_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.default_object_id)
    left outer join [%CATALOG%.]sys.extended_properties p on (p.major_id = o.object_id and p.minor_id = c.column_id and p.class =1)
where
   o.type in ('U', 'S', 'V')

[ and u.name = %.q:OWNER%]
[ and o.name=%.q:TABLE%]
order by 1, 2, 3
