未选择数据库-PHP和MySQL
我试图连接到我的数据库,当我运行代码时,出现错误。谁能告诉我我的PHP代码有什么错误和错误吗?谢谢。
Error: No database selected
include('.conf.php');$prof = $_GET['profile'];
$prof = addslashes(htmlentities($prof));
$query = "SELECT * FROM aTable where id = '".mysql_real_escape_string($prof)."'";
$info_array = mysql_query($query, $con) or die (mysql_error()).;
while($row = mysql_fetch_array( $info_array ))
{
echo $row['num1'];
echo "</br>";
echo $row['num2'];
echo "</br>";
echo $row['num3'];
echo "</br>";
echo $row['num4'];
};
mysql_close($con);
文件:
<?php $conf['db_hostname'] = "xxx";
$conf['db_username'] = "xxx";
$conf['db_password'] = "xxx";
$conf['db_name'] = "xxx";
$conf['db_type'] = "mysql";
$con = mysql_connect('xxx', 'xxx', 'xxx') or die (mysql_error());
$db = mysql_select_db("aTable", $con);
?>
回答:
除非您输入的密码不正确并且需要解决,否则运行一条GRANT
语句来授予对数据库用户的访问权限:
GRANT ALL PRIVILEGES ON aTable.* TO xxx@localhost IDENTIFIED BY 'password_for_xxx';
以上授予所有特权。通常最好只限制需要的内容。例如,如果您仅打算选择而不是修改数据,
GRANT SELECT ON aTable.* TO xxx@localhost IDENTIFIED BY 'password_for_xxx';
更新资料
由于您将数据库名称标识为dedbmysql
,因此将mysql_select_db()
调用更改为:
$db = mysql_select_db("dedbmysql", $con);
之后GRANT
,由于您的主机可能已经计算出正确的数据库权限,因此上面的语句可能是不必要的。
