修复 MySQL 数据库错误 #1064？

由于语法不正确，可能会出现数据库错误 #1064。例如，假设我们正在创建下表 -

mysql> create table DemoTable
   (
      UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
      UserName varchar(100),
      UserAge int,
      UserAddress varchar(200),
      UserCountryName varchar(100) ,
      isMarried boolean,
   );

这将产生以下输出，即错误 -

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 10

要消除上述错误，您需要删除最后一个逗号(,)。查询如下以消除错误 -

mysql> create table DemoTable
   (
      UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
      UserName varchar(100),
      UserAge int,
      UserAddress varchar(200),
      UserCountryName varchar(100),
      isMarried boolean
   );
