我希望查询仅在存在名为firstName 的列时才进行选择。如果列是名字，那么查询不应返回任何内容。
SELECT firstName as currentName from tableNew WHERE id = $Id
我尝试了下面的代码，但不起作用
SELECT binary firstName as currentName from tableNew WHERE id = $Id
你能帮忙吗？
最佳答案
On Unix, table names are case sensitive. On Windows, they are not.
Column, index, and stored routine names are not case sensitive on any platform, nor are column aliases.
