sql获取表的所有字段及属性

 select
      c.name as name,t.name as type
      ,convert(bit,c.IsNullable)  as isNULL
      ,convert(bit,case when exists(select 1 from sysobjects where xtype='PK' and parent_obj=c.id and name in (
          select name from sysindexes where indid in(
              select indid from sysindexkeys where id = c.id and colid=c.colid))) then 1 else 0 end)
                  as isKey
      ,convert(bit,COLUMNPROPERTY(c.id,c.name,'IsIdentity')) as isIdentity

      ,COLUMNPROPERTY(c.id,c.name,'PRECISION') as length
      ,ISNULL(CM.text,'') as defualtVal
      ,isnull(ETP.value,'') AS describe
      --,ROW_NUMBER() OVER (ORDER BY C.name) AS [Row]
 from syscolumns c
 inner join systypes t on c.xusertype = t.xusertype
 left join sys.extended_properties ETP on ETP.major_id = c.id and ETP.minor_id = c.colid and ETP.name ='MS_Description'
 left join syscomments CM on c.cdefault=CM.id
 where c.id = object_id('表名')

附上获取数据库内所有用户新增的表的语句

select * from sys.all_objects where type='U'
