查询库表字段信息 #695

Description

想要查询库表的字段和字段的comment。

sql语句如下: SELECT column_name, column_comment FROM information_schema.columns WHERE table_schema = 'your_database_name' AND table_name = 'your_table_name';

自己测试尝试了已有语法的组合,并未实现此功能,特地来请教大佬。

数据库基础属性表已提供: Table -> information_schema.tables Column -> information_schema.columns

当然也可以在 Access 表里注册下: table='tables', alias='Tables' table='columns', alias='Columns'
