我有一个 MySQL 命令:
CREATE DATABASE IF NOT EXISTS courses;
USE courses
CREATE TABLE IF NOT EXISTS teachers(
id INT(10) UNSIGNED PRIMARY KEY NOT NULL AUTO_INCREMENT,
name VAR_CHAR(50) NOT NULL,
addr VAR_CHAR(255) NOT NULL,
phone INT NOT NULL,
);
当我运行它时,我得到一个错误:
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 'VAR_CHAR(50) NOT NULL, addr VAR_CHAR(255) NOT
NULL, phone INT NOT NULL, )' at line 3
