从一栏价值中获取一栏名
原标题:get the column name from column value

鉴于该栏的价值,MySQL是否有办法获得该栏的名称?

例如,我有< 编码>STATES table和CITY的表格,其编号为NAME

页: 1 www.un.org/chinese/ga/president 我要问一下,将回到<代码>SATES和CITY>的栏目。 www.un.org/chinese/ga/president

我的预期产出可能好像

value             column         Table
-----               ------            -----
New York       NAME       STATES
New York       NAME       CITY

Above is just an example. In most of the cases i only know the column values and i dont know the Column names or the corresponding table Names. Generally I need not know on the diffrent random schema s. I am building a question answersing system that will work with multiple databases.

您将不得不询问信息_schema,以获得类似于。 该员额。 仅凭我nt智,我是你的最好之子。 如果你试图找到任何具有贵重价值的表格和栏,意味着你在每张表格中搜索每一栏。

除非你有非常简单的表格,否则那就是一个昂贵的问答。 你们需要拉开所有表格数据,然后将各栏具有对应值的所有表格检索。
