I have this query:

SELECT * from subcategory where prim = 'Waterworks and Corrosion' and category = 'Chlorine & Water Testing' order by so

When I run this "manually" against the database, it returns, correctly, 4 rows.

When I do the identical query in php, it returns zero rows. The php code is:

$pqrysc = "SELECT * from subcategory where prim = '" . $prd['pdesc'] . "' and category = '" . $cat . "' order by so";
echo $pqrysc . "<br>";
$pressc = mysql_query ($pqrysc, $Link);
$npsc = mysql_num_rows($pressc);
echo "num subcats = " . $npsc . "<br>";

the echo num subcats equals 0.

Does the & in the query cause an issue with mysql_query?

There are hundreds of other cases  where there is no & in the category where the mysql_query returns correctly.

I am aware that is code is not the latest correct interface between php & MySQL

Makes no difference, what do you get when you:

echo $pqrysc;

To Gary,

I get this:

SELECT * from subcategory where prim = 'Waterworks and Corrosion' and category = 'Chlorine & Water Testing' order by so

I copied the echoed version to phpmysql to do a "manual" sql, works fine.

Are you sure $Link is connecting to the right database?

p.s.
You need to get off mysql_query - obsolete (nearly)

1. Set error_reporting(E_ALL);
2. use var_dump() to check the values of $Link and $pressc and $npsc

And be sure to look at all of these outputs with "view source."  Your browser will render the ampersand from the character entity &amp; but your database will not find & == &amp;

The &amp; was the issue; I did str_replace, etc. & it FIXED it.

Thanks Ray,
