ADOX是ADO Extensions for DDL and Security，是微软对ADO技术的扩展，使用它我们可以 操作 数据库的结构。它是一个COM组件，估计以后在ADO.NET中会增加ADOX的一些功能。如果大家需要ADOX的一些资料，我可以提供。下面的一个例子就是使用ADOX来获得当前数据库的所有表。
摘抄
1.获取所有数据库名:
SELECT Name from Master..SysDatabases ORDER BY Name
2.获取所有表名:
SELECT Name from DatabaseName..SysObjects Where XType='U' ORDER BY Name
XType='U':表示所有用户表;
XType='S':表示所有系统表;
3.获取所有字段名:
SELECT Name from SysColumns WHERE id=Object_Id('TableName')
access :
1、获取所有用户名: Select name FROM Sysusers where status= '2' and islogin= '1' islogin= '1' :表示帐户 islogin= '0' :表示角色 status= '2' :表示用户帐户 status= '0' :表示糸统帐户 2、获取所有数据库名: Select Name FROM Master..SysDatabases orDER BY Name 3、获取所有表名: Select Name FROM DatabaseName..SysObjects Where XType= 'U' orDER BY Name XType= 'U' :表示所有用户表; XType= 'S' :表示所有系统表; 4、获取所有字段名: Select Name FROM SysColumns Where id=Object_Id( '表名' ') 5、获取数据库所有类型: select name from systypes 6、获取主键字段: Select name FROM SysColumns Where id=Object_Id( '表名' ) and colid=( select top 1 keyno from sysindexkeys where id=Object_Id( '表名' )) 7、获取表字段的基本信息: 程序代码 Select 字段名=rtrim(b. name ), 主键= CASE WHEN h.id IS NOT NULL THEN 'PK' ELSE '' END , 字段类型=type_name(b.xusertype)+ CASE WHEN b.colstat&1=1 THEN '[ID(' + CONVERT ( varchar , ident_seed(a. name ))+ ',' + CONVERT ( varchar ,ident_incr(a. name ))+ ')]' ELSE '' END , 长度=b.length, 允许空= CASE b.isnullable WHEN 0 THEN 'N' ELSE 'Y' END , 默认值= isnull (e.text, '' ), 字段说明= isnull (c.value, '' ) FROM sysobjects a, syscolumns b LEFT OUTER JOIN sysproperties c ON b.id = c.id AND b.colid = c.smallid LEFT OUTER JOIN syscomments e ON b.cdefault = e.id LEFT OUTER JOIN ( Select g.id, g.colid FROM sysindexes f, sysindexkeys g Where (f.id=g.id) AND (f.indid=g.indid) AND (f.indid>0) AND (f.indid AND (f.status&2048) 0) h ON (b.id=h.id) AND (b.colid=h.colid) Where (a.id=b.id) AND (a.id=object_id( '要查询的表' )) --要查询的表改成你要查询表的名称 orDER BY b.colid 程序代码 Select 表名= case when a.colorder=1 then d. name else '' end , 表说明= case when a.colorder=1 then isnull (f.value, '' ) else '' end , 字段序号=a.colorder, 字段名=a. name , 标识= case when COLUMNPROPERTY(a.id,a. name , 'IsIdentity' )=1 then '√' else '' end , 主键= case when exists( Select 1 FROM sysobjects where xtype= 'PK' and name in ( Select name FROM sysindexes Where indid in ( Select indid FROM sysindexkeys Where id=a.id AND colid=a.colid))) then '√' else '' end , 类型=b. name , 字段长度=a.length, 占用字节数=COLUMNPROPERTY(a.id,a. name , 'PRECISION' ), 小数位数= isnull (COLUMNPROPERTY(a.id,a. name , 'Scale' ),0), 允许空= case when a.isnullable=1 then '√' else '' end , 默认值= isnull (e.text, '' ), 字段说明= isnull (g.[value], '' ) FROM syscolumns a left join systypes b on a.xusertype=b.xusertype inner join sysobjects d on (a.id=d.id) and (d.xtype= 'U' ) and (d. name 'dtproperties' ) left join syscomments e on a.cdefault=e.id left join sysproperties g on (a.id=g.id) and (a.colid=g.smallid) left join sysproperties f on (d.id=f.id) and (f.smallid=0) --where d.name='要查询的表' --如果只查询指定表,加上此条件 order by a.id,a.colorder
