简单的PHP/MySQL创建表脚本 [英] Simple PHP/MySQL Create Table Script

问题描述

因此，我拥有此脚本仅用于在数据库中创建表.我已经从一个旧脚本中复制了该脚本，该脚本现在可以正常工作.为什么这个不起作用?任何人?

So I have this script just to create a table in my database. I've copied it over from an old script I did that is working right now. How come this one is not working? Anyone?

我遇到的错误是"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 "'= varchar (20) NOT NULL, column_two = int NOT NULL auto_increment, column_thre' at line 2"

<?php

include("server_connect.php");

mysql_select_db("assignment5");

$create = "CREATE TABLE tbltable (
column_one = varchar (20) NOT NULL,
column_two = int NOT NULL auto_increment,
column_three = int NOT NULL,
column_four = varchar (15) NOT NULL,
column_five = year,
PRIMARY KEY = (column_one)
)";

$results = mysql_query($create) or die (mysql_error());

echo "The tables have been created";

?>

推荐答案

按照建议删除所有=:

$create = "CREATE TABLE tbltable (
column_one varchar (20) NOT NULL,
column_two int NOT NULL auto_increment PRIMARY KEY,
column_three int NOT NULL,
column_four varchar (15) NOT NULL,
column_five year
)";

每个表都应具有主键，并且您必须将AUTO_INCREMENT列指定为PRIMARY KEY.在这种情况下，AUTO_INCREMENT列为column_two，我将其设置为PRIMARY KEY.

Each and every table should have a primary key and you must specify AUTO_INCREMENT column as PRIMARY KEY. In this case, the AUTO_INCREMENT column is column_two and I've set that as the PRIMARY KEY.
