《Mysql学习mysql中的保留字段产生的问题》要点：
本文介绍了Mysql学习mysql中的保留字段产生的问题，希望对您有用。如果有疑问，可以联系我们。
MYSQL入门You have an error in your SQL syntax; check the manual that corresponds to your MySQL server versio・・・・这句话对于咱们并不陌生,无非就是多了“,”之类的问题.但是你如果无意之中添加了一个mysql中的保留字段作为数据库中存贮的字段名,悲剧就这样发生了.
MYSQL入门前几天因为功能的临时变更,需要给数据表添加一个字段用来区别导入的批次,我就在mysql中添加了group字段,没想到我的噩梦就此展开・・・・・
本来程序已经接近收尾,本想着今早来公司给程序来个欢乐的结尾,没想到・・・・每次导入excel表总是提示我sql语句错误,我变在sql语句上添添减减,也没有把错误搞定,整整一个上午外加下午两个小时,简直已经到了抓狂的程度.简直要跪地苦思冥想,但是还是没有搞定这个错误.
把问题放在一边,继续搞其他的东西・・・・当在写一个group by 语句时,突然意识到,group 是mysql的一个保留字,就此问题迎刃而解.切记切记,多么痛的领悟啊
MYSQL入门mysql的保留字段
MYSQL入门在MySQL中,下表中的字显式被保留.其中大多数字进制被标准SQL用作列名和/或表名(例如,GROUP).少数被保留了,因为MySQL需要它们,在MySQL中,当表名或字段名乃至数据库名和保留字冲突时,在sql语句里可以用撇号()括起来,当让我们一般都尽量少使用这些保留的字段.
