• sql读取 所有表、结构 描述


    需要:读取库里面所有 表、以及表描述、 列、列描述

    --后续 :记录sql管理维护

    场景1:查看所有的表名称(很多时候 不知道表,也不知道表叫什么名称,只记得备注)。 

    vw_tableDes

    create view [dbo].[vw_TableDes]
    as
    select TableCode=object_name(major_id)
        ,TableName=cast([value] as nvarchar(100))
    from sys.extended_properties 
    where minor_id=0 

    要求在建表的时候 需要维护扩展属性:

    场景2:有查看所有表,就有查看字段
