下文讲述-采用sql脚本获取指定表中所有列对应的说明信息,
脚本如下所示:
</span>
 

SELECT
(case when a.colorder=1 then d.name else '' end) [数据表名称],
a.colorder [列顺序],
a.name [列名称],
b.name as [列类型],
b.length as [列长度],
g.[value] AS [列说明信息]
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 sys.extended_properties g
on a.id=g.major_id AND a.colid = g.minor_id 
WHERE d.[name] ='IError'--数据表名称
order by a.id,a.colorder
