用Sql語句生成Sqlserver數據字典

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

--字段序號=a.colorder,

字段名=a.name,

--標識=case when COLUMNPROPERTY( a.id,a.name,’IsIdentity’)=1 then ’√’else ’’ end,

類型=b.name,

--佔用字節數=a.length,

長度=COLUMNPROPERTY(a.id,a.name,’PRECISION’),

小數位數=isnull(COLUMNPROPERTY(a.id,a.name,’Scale’),0),

允許空=case when a.isnullable=1 then ’√’else ’’ end,

默認值=isnull(e.text,’’),

字段說明=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
