Sql Server 2000 2005 用Sql语句生成Sqlserver数据字典

Sql Server 2000 版本：

SELECT 表名=case when a.colorder=1 then d.name 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,

--占用字节数=a.length,

长度=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.xtype=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

order by a.id,a.colorder
