MySQL允许部分关键字用做未引起来的识别符,因为许多人以前曾使用过它们。下面列出了一些例子:

  • ACTION

  • BIT

  • DATE

  • ENUM

  • NO

  • TEXT

  • TIME

  • TIMESTAMP

今天在做项目的时候,将CHARACTER做成了,字段的名称,和mysql的关键字,冲突了,还调了半天,一看在知道,CHARACTER是mysql的关键字,留个标记,呵呵!!

遇到关键字使用时冲突,查询可以使用``括住关键字。使用的符号是半角的``,即esc下面的那个按键。

今天在重MySql 语句时出现错误:
select * from kw_photo where albumId=102 order by order
原来order字段跟关键字冲突,需要用''引起来。

select * from kw_photo where albumId=102 order by 'order'

这样就没问题了。
