sqlserver生成表结构文档的方法

只说原理了，具体 可以自己使用程序去生成htm或word文档。

1、首先获取所有的表

SELECT name, id From sysobjects WHERE xtype = 'u' ORDER BY name ASC

2、根据表名查询字段信息

select syscolumns.name, syscolumns.length, systypes.name   as   typename, sys.extended_properties.[value] AS tname,syscolumns.isnullable  from   syscolumns join systypes   on     syscolumns.xtype=systypes.xtype   and   systypes.name <> 'sysname' LEFT OUTER JOIN sys.extended_properties ON ( sys.extended_properties.minor_id = syscolumns.colid AND sys.extended_properties.major_id = syscolumns.id) where   syscolumns.id   in (select   id   from   sysobjects   where   name= 't_sale')
