以下可以正常显示：

SELECT
      (case when a.colorder=1 then d.name else \'\' end)表名,
      d.name 表名1,
      a.colorder 字段序号,
      a.name 字段名,
      (case when COLUMNPROPERTY( a.id,a.name,\'IsIdentity\')=1 then \'√\'else \'\' end) 标识,
      (case when (SELECT count(*)
      FROM sysobjects
      WHERE (name in
                (SELECT name
               FROM sysindexes
               WHERE (id = a.id) AND (indid in
                         (SELECT indid
                        FROM sysindexkeys
                        WHERE (id = a.id) AND (colid in
                                  (SELECT colid
                                 FROM syscolumns
                                 WHERE (id = a.id) AND (name = a.name))))))) AND
             (xtype = \'PK\'))>0 then \'√\' else \'\' end) 主键,
      (case when b.name=\'nvarchar\' then b.name+\'(\'+convert(nvarchar(100),columnproperty(a.id,a.name,\'PRECISION\'))+\')\' else b.name end) 类型,
      a.length 占用字节数,
      columnproperty(a.id,a.name,\'PRECISION\') as 长度,
      isnull(COLUMNPROPERTY(a.id,a.name,\'Scale\'),0) as 小数位数,
      (case when a.isnullable=1 then \'是\'else \'否\' end) 允许空,
      isnull(e.text,\'\') 默认值,
      isnull(g.value,\'\') AS 字段说明 
FROM  syscolumns  a left join systypes b
on  a.xtype=b.xusertype
inner join sysobjects d
on a.id=d.id  and  d.xtype=\'U\' 
left join syscomments e 
on a.cdefault=e.id
left join sys.extended_properties g
on a.id=g.major_id AND a.colid = g.Minor_id 
where 1=1
--and d.name=\'t_test\' --指定单个表名
order by d.name,a.id,a.colorder

 

下面想做一个简单的查询（未完，待续）

Declare @tableName varchar(50)
Set  @tableName = \'表名\'

select syscolumns.name as 字段名, syscolumns.length as 长度, 
systypes.name   as   \'数据类型\', 
sys.extended_properties.[value] AS \'字段说明\',
syscolumns.isnullable as \'是否允许空值\'  
from   syscolumns join systypes   on     syscolumns.xtype=systypes.xtype   
and   systypes.name <> \'sysname\' 
LEFT OUTER JOIN sys.extended_properties ON ( sys.extended_properties.minor_id = syscolumns.colid AND sys.extended_properties.major_id = syscolumns.id) 
where   syscolumns.id   in (select   id   from   sysobjects   where   name= @tableName)
