我试图用4个表创建一个数据库。当我运行我的代码时，它会创建第一个表，但不会创建第三个表。这是因为第二个表没有将存储引擎更改为myISAM，但我无法弄清楚为什么它没有这样做。这里是我的代码：SQL数据库问题
<?php
require_once 'conn.php';
$sql= <<<EOS
CREATE TABLE IF NOT EXISTS cms_access_levels (
access_lvl tinyint(4) NOT NULL auto_increment,
access_name varchar(50) NOT NULL default'',
PRIMARY KEY(access_lvl)
)
EOS;
$result= mysql_query($sql) or
die(mysql_error());
$sql= "INSERT IGNORE INTO cms_access_levels " .
"VALUES(1, 'Users'), " .
"(2, 'Moderator'), " .
"(3, 'Administrator')";
$result= mysql_query($sql) or
die(mysql_error());
$sql= <<<EOS
CREATE TABLE IF NOT EXISTS cms_articles ENGINE = MYISAM (
article_id int(11) NOT NULL auto_increment,
author_id int(11) NOT NULL default '0',
is_published tinyint(11) NOT NULL default '0',
date_submitted datetime NOT NULL default '0000-00-00 00:00:00',
date_published datetime NOT NULL default '0000-00-00 00:00:00',
title varchar(255) NOT NULL default '',
body mediumtext NOT NULL,
PRIMARY KEY(article_id),
KEY IdxArticle(author_id, date_submitted),
FULLTEXT KEY IdxText(title, body)
)
EOS;
$result= mysql_query($sql) or
die(mysql_error());
$sql= <<<EOS
CREATE TABLE IF NOT EXISTS cms_comments (
comment_id int(11) NOT NULL auto_increment,
article_id int(11) NOT NULL default '0',
comment_date datetime NOT NULL default '0000-00-00 00:00:00',
comment_user int(11) NOT NULL default '0',
comment text NOT NULL,
PRIMARY KEY(comment_id),
KEY idxComment(article_id)
)
EOS;
$result= mysql_query($sql) or
die(mysql_error());
$sql= <<<EOS
CREATE TABLE IF NOT EXISTS cms_users (
user_id int(11) NOT NULL auto_increment,
email varchar(255) NOT NULL default '',
password varchar(50) NOT NULL default '',
name varchar(100) NOT NULL default '',
access_lvl tinyint(4) NOT NULL default '1',
PRIMARY KEY(user_id),
UNIQUE KEY uniq_email(email)
)
EOS;
$result= mysql_query($sql) or
die(mysql_error());
$adminemail= "[email protected]";
$adminpass= "graysen7";
$adminname= "olle";
$sql= "INSERT INTO cms_users " .
"VALUES (NULL, '$adminemail', '$adminpass', '$adminname', 3)";
$result= mysql_query($sql) or
die(mysql_error());
echo "<html><head><title>CMS Tables Created</title></head><body>";
echo "CMS Tables created. Here is the initial login information: <br />";
echo "<ul><li><strong>Login:</strong> " . $adminemail . "</li><br />";
echo "<li><strong>Password:</strong> " . $adminpass . "</li><br />";
echo "<a href='login.php'>Login</a> to the site now.";
echo "</ul></body></html>";
?>
