请帮我看看一段数据库管理的代码为何无效
<?php
$dbcon = mysql_connect("localhost","××××","×××××");
if(!$dbcon)
{
die('could not connect: ' . mysql_error());
}
echo "mysql connected\n";
mysql_query("CREATE DATABASE soap_calc",$dbcon);
mysql_select_db("soap_calc",$dbcon);
$sql = "CREATE TABLE oils
(
ID int NOT NULL AUTO_INCREMENT,
CN_Name varchar(15),
EN_Name varchar(30),
SAP decimal(5,3),
SAP_NaOH decimal(5,3),
Non_Sapon decimal(5,3),
Iodine decimal(10,3),
PRIMARY KEY (ID)
)";
mysql_query($sql,$dbcon);
//read items from file
$file = fopen("oiltable", "r");
while(!feof($file))
{
fscanf($file,"%s %s %s %s %s \n",$CNN,$ENN,$NAOH,$KOH,$INS);
mysql_query("INSERT INTO oils (CN_Name,EN_Name,SAP,SAP_NaOH)
VALUES ('$CNN','$ENN','$KOH','$NAOH')");
}
mysql_close($dbcon);
echo "db finished\n";
?>
