php - 运行 create table 时不断收到错误消息 1064

Question

我是 PHP 和 MySQL 的新手，在我正在从事的项目中遇到了一些麻烦。我不断收到错误消息 #1064 - 您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，了解在 '',' 附近使用的正确语法

表ea_cellcarrier的表结构

CREATE TABLE IF NOT EXISTS ea_cellcarrier(
id INT NOT NULL AUTO_INCREMENT  ',' PRIMARY KEY (  `id` ) ,
cellco VARCHAR( 30 )  ','cellurl VARCHAR( 30 )
)

转储表的约束

表ea_appointments的约束

ALTER TABLE  `ea_appointments` 
ADD CONSTRAINT  `ea_appointments_ibfk_2` 
                 FOREIGN KEY (  `id_users_customer` ) 
                 REFERENCES  `ea_users` (  `id` ) ON DELETE CASCADE ON UPDATE CASCADE ,
ADD CONSTRAINT  `ea_appointments_ibfk_3` 
                 FOREIGN KEY (  `id_services` ) 
                 REFERENCES  `ea_services` (  `id` ) ON DELETE CASCADE ON UPDATE CASCADE ,
ADD CONSTRAINT  `ea_appointments_ibfk_4` 
                 FOREIGN KEY (  `id_users_provider` ) 
                 REFERENCES  `ea_users` (  `id` ) ON DELETE CASCADE ON UPDATE CASCADE ;

MySQL 说:文档

1064 - 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 '',' PRIMARY KEY (id), cellco VARCHAR(30)',' cellurl VARCHAR(30)) Co' at line 5

Answer 1

CREATE TABLE IF NOT EXISTS ea_cellcarrier
(
  id INT NOT NULL AUTO_INCREMENT, 
  cellco  VARCHAR(30) ,
  cellurl VARCHAR(30) ,
  PRIMARY KEY (`id`) 
)
