--作用：用于sql server 2005 导出用户表数据字典

--作者：郭强--时间：年月日--用法如下：

--1 默认导出当前数据库中所有用户表(xtype = 'u')的数据字典；

--2 可以在xtype = 'u'替换为如下所示语句xtype = 'u' and name in ('son','Person') 导出自定义的表的数据字典；

--3 可以利用集成服务SSIS导出数据字典的excel文件，形成文档；

------------------------------------------------------

select sysobjects.name as "表名",syscolumns.name as "字段名",

case when systypes.name in ('binary','char','nchar') then (systypes.name + '(' + cast(syscolumns.prec as varchar(50))+ ')')

when systypes.name in ('decimal','numeric') then (systypes.name + '(' + cast(syscolumns.prec as varchar(50)) + ',' +cast(syscolumns.scale as varchar(50)) + ')')

when systypes.name in ('nvarchar','varchar','varbinary') then (case when syscolumns.prec = -1 then (systypes.name +'(MAX)') else (systypes.name + '(' + cast(syscolumns.prec as varchar(50)) + ')') end)

else systypes.name end as "字段类型",

syscomments.text as "默认值", case when syscolumns.isnullable = 1 then 'Y' else 'N' end as "能否为空",

cast(sys.extended_properties.value as varchar(1024)) as "备注"

from syscolumns inner join systypes on syscolumns.xtype = systypes.xtype left join sysobjects

on syscolumns.id = sysobjects.id left outer join sys.extended_properties

on ( sys.extended_properties.minor_id = syscolumns.colid and sys.extended_properties.major_id = syscolumns.id)left outer join syscomments

on syscolumns.cdefault = syscomments.id where syscolumns.id in (select id from sysobjects where xtype = 'u') and(systypes.name <> 'sysname') order by sysobjects.name asc
