在MariaDB中更改列名称 [英] Change column name in MariaDB

问题描述

我在此数据库的此列中包含一个空格键，我想对其进行更改.

I have this column in this database with a spacebar included, which I want to change.

ALTER TABLE . CHANGE COLUMN `Anzahl Personen` AnzahlPersonen int(11); 

在命令行中使用此行之后，输出如下:

After using this line in the command line the output is as following:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'CHANGE COLUMN `Anzahl Personen` AnzahlPersonen int(11)' at line 1

是的，我不知道我在做什么错.

Yeah, I have no Idea, what I am doing wrong.

推荐答案

如果您使用点(.)代替表名，这就是您出错的原因. 您必须指定表名:

If you are using dot (.) instead of table name that is why you have error. You have to specify table name:

ALTER TABLE `table_name` CHANGE COLUMN `Anzahl Personen` AnzahlPersonen int(11);
