USE waterloo;

DROP TABLE IF EXISTS waterloo;
CREATE TABLE waterloo

id              int unsigned NOT NULL auto_increment,   # Unique ID for the record
building        varchar(255) NOT NULL,                  # Name of building
floor           int unsigned NOT NULL,                  # Floor of building

lines           int unsigned NOT NULL,                  # Length of lines at peak hours
graffiti        int unsigned NOT NULL,                  # Amount of graffiti on the walls
PRIMARY KEY     (id)

我收到以下错误：

错误1064（42000）：您的SQL语法有错误;检查手册，对应右边的MySQL服务器版本在'lines int unsigned NOT NULL，graffiti int附近使用的语法第11行的无符号NOT NULL）

Answer 1

LINES是MySQL中的保留字。但是，您仍然可以将其用作列名。只需将它包装在背景中

`lines`

Answer 2

行是MySQL中的保留字 - 在它周围添加刻度并且它应该可以工作。
