[點(diǎn)晴永久免費(fèi)OA]SQL Server獲取數(shù)據(jù)表字段（表的字段和類型信息）
方法一（紅色userinf為表名）：
SELECT
表名=case when a.colorder=1 then d.name else '' end,
表說明=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 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='userinf'
order by a.id,a.colorder
方法二（紅色userinf為表名）：
select sc.name as field_id, st.name as field_type from syscolumns sc,systypes st where sc.xtype=st.xtype and sc.id in(select id from sysobjects where xtype='U' and name='userinf') and st.name<>'sysname' order by sc.name;
