Question

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
gender          varchar(255) NOT NULL,                  # Gender of bathroom
location        int unsigned NOT NULL,                  # Convenience of location of     bathroom
cleanliness     int unsigned NOT NULL,                  # Cleanliness of bathroom
stalls          int unsigned NOT NULL,                  # Number of stalls
noise           int unsigned NOT NULL,                  # Ambient noise
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:

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 'lines int unsigned NOT NULL, graffiti int unsigned NOT NULL )' at line 11

Answer 1

LINES 是 MySQL 中的保留字。不过，您仍然可以将其用作列名称。只需将其包裹在背面即可

`lines`
