1. 列注释

原来代码：

 {OWNER, TABLE, S, COLUMN, DTTPCODE, LENGTH, SIZE, PREC, COMPUTE, NOTNULL, IDENTITY, DOMAIN, DEFAULT, ExtIdentitySeedInc, COMMENT, ExtCollation, ExtIdtNotForReplication, ExtDeftConstName, Sparse, FileStream, 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,
    (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)
    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)

where
   o.type in ('U', 'S', 'V')
[  and u.name = %.q:OWNER%]
[  and o.name=%.q:TABLE%]
order by 1, 2, 3

 

解决方案：      

在PD的 tools-->resources-->dbms-->sql server 2008打开DBMS属性窗口，在general选项卡中选择Microsoft SQL Server 2008-->script-->objects-->column-->SQLlistquery修改其中的内容为:

{OWNER, TABLE, S, COLUMN, DTTPCODE, LENGTH, SIZE, PREC, COMPUTE, NOTNULL, IDENTITY, DOMAIN, DEFAULT, ExtIdentitySeedInc, COMMENT, ExtCollation, ExtIdtNotForReplication, ExtDeftConstName, Sparse, FileStream, 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),e.value),
    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)
    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 e on (e.class=u.schema_id and e.major_id=o.object_id and e.minor_id = c.column_id and e.name=N'MS_Description')
where
   o.type in ('U', 'S', 'V')
[  and u.name = %.q:OWNER%]
[  and o.name=%.q:TABLE%]
order by 1, 2, 3

 

 

2. 表注释

原为：

{OWNER, TABLE, TABLE_TYPE, COMMENT}

select
   u.name,
   o.name,
   case (o.type) when 'S' then 'SYSTEM TABLE' else 'TABLE' end,
   (select convert(varchar(8000), value) from ::fn_listextendedproperty(NULL, 'user', u.name, 'table', o.name, null, null) where name = 'MS_Description') as coln
from
   [%CATALOG%.]sys.sysobjects o
   join [%CATALOG%.]sys.schemas  u on (u.schema_id = o.uid)
where
   o.type in ('U', 'S')
[  and u.name = %.q:OWNER%]
order by 1, 2

解决办法：

在PD的 tools-->resources-->dbms-->sql server 2008打开DBMS属性窗口，在general选项卡中选择Microsoft SQL Server 2008-->script-->objects-->Table-->SQLlistquery修改其中的内容为:

{OWNER, TABLE, TABLE_TYPE, COMMENT}

select
   u.name,
   o.name,
   case (o.type) when 'S' then 'SYSTEM TABLE' else 'TABLE' end
   ,convert(varchar(8000), e.value) as coln
from
   [%CATALOG%.]sys.sysobjects o
   join [%CATALOG%.]sys.schemas  u on (u.schema_id = o.uid)
   left join [%CATALOG%.]sys.extended_properties e on (e.class=u.schema_id and e.major_id=o.id and e.minor_id=0 and e.name=N'MS_Description')
where
   o.type in ('U', 'S')
[  and u.name = %.q:OWNER%]
order by 1, 2

3. 反向工程后，在Users中删除dbo用户，然后生成脚本即可运行。
