我試圖用4個表創建一個數據庫。當我運行我的代碼時，它會創建第一個表，但不會創建第三個表。這是因爲第二個表沒有將存儲引擎更改爲myISAM，但我無法弄清楚爲什麼它沒有這樣做。這裏是我的代碼：SQL數據庫問題
<?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,

$result= mysql_query($sql) or

$sql= <<<EOS

)
EOS;
$result= mysql_query($sql) or

$sql= <<<EOS

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>";
?>
任何幫助，不勝感激！
非常好！這就是我需要的，謝謝！ –
