原文:【SQL】用Sql Server自动生产html格式的数据字典

本文软件环境：Sql Server 2008。

1.打开sql server管理器，给选定的表添加描述信息，给指定的字段添加描述信息。

直接在表上或者字段上右键属性-扩展属性，添加一个key-value对，key就是“MS_Description",value就是你自己的描述。详细见下图：

给字段添加描述的过程与上述一致，不在赘述。

2.执行以下这段sql语句，然后复制查询到的结果到文本，保存为html即可。

Set nocount on

DECLARE @TableName nvarchar(35)

DECLARE Tbls CURSOR

FOR

    Select distinct Table_name

    FROM INFORMATION_SCHEMA.COLUMNS

    --put any exclusions here

    --where table_name not like '%old'

    order by Table_name

    AND exprop.name = 'MS_Description'

    WHERE (tbl.name = @TableName and

    exprop.class = 1) --I don't wand to include comments on indexes

    ORDER BY clmns.column_id ASC

    PRINT '</tr></table>'

    PRINT '</div>'

    FETCH NEXT FROM Tbls

    INTO @TableName

END

PRINT '</body></HTML>'

CLOSE Tbls

DEALLOCATE Tbls

如下图，第二个框是”以文本方式显示结果”，不要选错了：

3.最终显示效果

后记：

如果你觉得MS_Description这个key写起来太麻烦，当然也可以自定义，不过那段sql代码也要记得改一下。
