SQL公用方法---获取表名级字段名
--查询表字段
select a.name ,b.name as type ,dis.value as description,tb.value as tbName,
case a.isnullable when 1 then '空' else '非空' end as [isNull]from syscolumns a
inner join systypes b on a.xtype=b.xtype and a.xusertype=b.xusertype
left join sys.extended_properties dis on dis.major_id=a.id and dis.minor_id=a.colorder
left join sys.extended_properties tb on tb.major_id=a.id and tb.minor_id=0
where a.id=object_id('Table_1')
--主键
EXEC sp_pkeys @table_name='A1AccUser'
--查询表
select [id], [name] from [sysobjects] where [type] = 'u' order by [name]
