?获取SQLserver2005表结构?

?不要喷，我只是做一下笔记。

--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('your tablename')

--获取SqlServer中表结构 主键，及描述
declare @table_name as varchar(max)
set @table_name = 'your tablename'
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

--单独查询表递增字段

select [name] from syscolumns where
id=object_id(N'your tablename') and COLUMNPROPERTY(id,name,'IsIdentity')=1

--获取表主外键约束

exec sp_helpconstraint?? 'your tablename' ;
