如何在Sql2008中獲取表字段屬性和注釋?

select b.[value] from sys.columns a left join sys.extended_properties b on a.object_id=b.major_id

and a.column_id=b.minor_id inner join sysobjects c on a.column_id=c.id

and a.[name]='列名' and c.[name]='表名'

SELECT

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

表說(shuō)明=case when a.colorder=1 then isnull(f.value,'') else '' end,

字段序號(hào)=a.colorder,

字段名=a.name,

標(biāo)識(shí)=case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end,

主鍵=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,

類(lèi)型=b.name,

占用字節(jié)數(shù)=a.length,

長(zhǎng)度=COLUMNPROPERTY(a.id,a.name,'PRECISION'),

小數(shù)位數(shù)=isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0),

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

默認(rèn)值=isnull(e.text,''),

字段說(shuō)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 sys.extended_properties g on a.id=g.major_id and a.colid=g.minor_id

left join sys.extended_properties f on d.id=f.major_id and f.minor_id=0

--where d.name='orders' --如果只查詢(xún)指定表,加上此條件

order by a.id,a.colorder
