获取SqlServer2005表结构

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、获取SqlServer中表结构 主键，及描述

declare@table_nameasvarchar(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

 3、单独查询表递增字段

select [name] from syscolumns where 
id=object_id(N'你的表名') and COLUMNPROPERTY(id,name,'IsIdentity')=1
