获取SqlServer2005表结构(字段，主键，外键，递增，描述)

1.获取表的基本字段属性

--获取SqlServer中表结构 
SELECT syscolumns.name,systypes.name,syscolumns.isnullable,
syscolumns.length 
FROM syscolumns, systypes 
WHERE syscolumns.xusertype = systypes.xusertype 
AND syscolumns.id = object_id('你的表名')

2.如果还想要获取字段的描述信息则

--获取SqlServer中表结构 主键，及描述

declare @table_name as varchar(max)

set @table_name = '你的表名' 

select sys.columns.name, sys.types.name, sys.columns.max_length, sys.columns.is_nullable, 

  (select count(*) from sys.identity_columns where sys.identity_columns.object_id = sys.columns.object_id and sys.columns.column_id = sys.identity_columns.column_id) as is_identity ,

  (select value from sys.extended_properties where sys.extended_properties.major_id = sys.columns.object_id and sys.extended_properties.minor_id = sys.columns.column_id) as description

  from sys.columns, sys.tables, sys.types where sys.columns.object_id = sys.tables.object_id and sys.columns.system_type_id=sys.types.system_type_id and sys.tables.name=@table_name order by sys.columns.column_id
