採用sql語句生成資料字典,獲得表字段及說明

--獲得表common_channel欄位及說明

select A.name,B.value from syscolumns A,sysproperties B  where A.id=B.id and A.id=Object_id('common_channel') and A.colorder=B.smallid;


--採用sql語句生成資料字典

SELECT  表名=case when a.colorder=1 then d.name else '' end, 
 --欄位序號=a.colorder, 
 欄位名=a.name, 
欄位說明=isnull(g.[value],''),
--標識=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,
 
 欄位型別=b.name, 
 --佔用位元組數=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 '是'else '否' end, 
 預設值=isnull(e.text,'無')
