trying to dump out table info

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all

I am not sure why this is failing/giving error. I am quite new at PHP/ Mysql, and apologize for what will undoubtedly end up being a trivial error on my part.
Here is my code:

$db_billing=mysql_connect(localhost,metheuser,mypass,billing);
if (!$db_billing) { die('Could not connect: ' . mysql_error()); }

	$sql = "SHOW TABLES";
	
	$result = mysql_query($sql);
	
	foreach(mysql_fetch_assoc($result) as $k => $v) { //line 62
	$ssql = "DESCRIBE ".mysql_real_escape_string($v);
	$rresult = mysql_query($ssql);
	echo "<b>".$k."</b>:<br />\n";
	echo "<pre>\n";
	print_r(mysql_fetch_assoc($rresult));
	echo "</pre>\n";
	echo "<br />\n";
	}

which is giving this error:

Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /home/meee/public_html/somedir/test.php on line 62

I read about:
-mysql_fetch_assoc
-mysql_query
-SHOW TABLES

but do not see why this should be failing. Why isn't $result a ' valid MySQL result resource'?

-G
