select name tablename from jsj01..sysobjects where type='U' and name not in ('dtproperties')
--查詢表里的字段信息
---docs為表名 ---- select * from syscolumns where id = object_id('docs')
----查詢數據庫中所有類型 ----select name,xtype from systypes
----兩表聯查，顯示表中所有字段和對應的數據類型
----syscolumns里字段‘xtype' 對應 systypes里的 ‘xusertype' ,systypes 里的‘name'字段就是字段的數據類型 ----docs 為表名 select a.name as fieldname,b.name as type from syscolumns as a join systypes as b on a.xtype = b.xusertype where id=object_id('docs')
----docs為數據表名 ： 查詢表字段、類型、說明
select a.name fieldname,b.name type,c.value comment from syscolumns as a full join systypes as b on a.xtype = b.xusertype full join ::fn_listextendedproperty(NULL, 'user', 'dbo', 'table', 'docs', 'column', default) as c ----這是2000版本，2005把user改為schema on a.name=c.objname COLLATE Chinese_PRC_CI_AS -----排序規則（有時不加也可以，如果兩表的排序規則不同，則會報錯） --join sysproperties c --on a.id=c.major_id where id=object_id('docs')
select column_name as primarykey,* from [jsj01].INFORMATION_SCHEMA.KEY_COLUMN_USAGE where Table_name='docs' and constraint_name like 'fk_%'
--select * from sysobjects WHERE OBJECT_NAME(sysobjects.parent_obj)='docs' --and xtype='pk' --select * from sysconstraints where id = object_id('docs') --select * from syscolumns where id = object_id('docs') --select * from sysindexes --select * from sysindexkeys
----查詢表中自動增長的字段，沒有為空，如果有就只有一個 ----docs為表名
SELECT a.name column_name,b.name data_type FROM syscolumns a,systypes b WHERE a.id=object_id('docs') and a.xtype = b.xusertype AND a.autoval is not null
