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')
运行效果

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


运行效果

3.单独查询表的递增字段
--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
运行效果

4.获取表的主外键
--获取表主外键约束
exec sp_helpconstraint  '你的表名' ;
运行效果
