对于报错解析：很明显这是语法错误，我上看下看，左看右看，都没有看出问题来。

在pycharm中执行报语法错误，但是我复制到mysql数据库去执行又是正常的。就很纳闷。

一、执行的语句

二、分析

1、 在pycharm运行就报错了：

 2、在mysql运行是正常的

3、错误寻找

4、答案在这：

一、执行的语句

原来的执行语句的功能："""如果存在表就卸载表；然后创建表"""

二、分析

1、 在pycharm运行就报错了：

 2、在mysql运行是正常的

3、错误寻找

找了很多，有人说是使用的字段有可能是关键字，要用 `` 把关键字包起来，我也包起来了，其他什么逗号，括号都没有问题。毕竟在mysql查询里可以运行，那就语句是没有问题的。

然后想起昨晚第一次运行都没有问题，后来我是改了哪里出了问题？

4、答案在这：

因为在pycharm里，上述sql语句中，我同时执行了两个命令！！！

要把DROP和CREATE分开两次运行，不能放在一个excute执行！！！
