SQL Server2008中通过SQL获取表结构

新增数据用户，角色为public，映射到待获取表结构的数据库上，授与用户在该数据库上的身份为db_owner

执行如下SQL语句：

select syscolumns.name as [Name] ,systypes.name as [Type],syscolumns.length AS [Size],syscolumns.xprec As [Precision], ISNULL(syscolumns.scale, 0) AS [Scale],sys.extended_properties.value as [Mark],syscolumns.isnullable as [NULL],(Case when exists(select 1 from sysobjects inner join sysindexes on sysindexes.name = sysobjects.name   inner join sysindexkeys on sysindexes.id = sysindexkeys.id and  sysindexes.indid = sysindexkeys.indid  where xtype='PK' and parent_obj = syscolumns.id     and sysindexkeys.colid = syscolumns.colid) then 1 else 0 end) AS [PK],(Case syscolumns.status when 128 then 1 else 0 end) AS [Identity] from syscolumns   inner join systypes on (  syscolumns.xtype = systypes.xtype   and systypes.name <>'_default_'    and systypes.name<>'sysname')   left outer join sys.extended_properties on (  sys.extended_properties.major_id=syscolumns.id    and minor_id=syscolumns.colid)   where syscolumns.id = (select id from sysobjects where name='NDS_TFileForm')  order by syscolumns.colid
