Re: Trouble running a select query against a database, when I know the connection is working, and the data is there

Thanks.

Will try it out - think the .count is just related to $arr being sort of an array of records - and think I got it out of the PHP tutorial from w3schools.com, and it's worked on other pages.

Anyway, the following does now seem to work fine:

$qry = mysql_query($sql);
if (mysql_num_rows($qry) > 0)
{
echo "<ul>";
while($row = mysql_fetch_array($qry))
  {
echo "<li>" . $row['LinkName'] . " - " . $row['LinkDescription'] . " - ";
echo "<a href='" . $row['LinkURL'] . "' target='_blank'>" . $row['LinkURL'] . "</a></li>";
  }
echo "</ul>";
}

Thanks again

Stay well

    I am trying to simply just loop through a set of records to spit out <li /> tags for the data therein, and on the same page, it's successfully running another query against the same connection - which I have also tried turning off just in case it was a problem with running two queries against the same connection (really don't think so), but it just tells me there are no records being returned, although I have tried simplifying the sql statement, pulling records from another table, etc. etc., and I really don't know what am doing wrong with this really simple bit of scripting:

    $qry = mysql_query("select CatName from tblCats where Id = " . $_REQUEST['id']);
    $arr = mysql_fetch_array($qry);
    echo "<h2>" . $arr['CatName'] . "</h2>";
    //that part works fine
    $sql = "select Id, CatID, LinkName, LinkDescription, LinkURL from tblLinks where CatID = " . $_REQUEST['id'] . ";";
    //the SQL statement seems to come out fine as well if I echo it out to the browser
    $qry = mysql_query($sql);
    $arr = mysql_fetch_array($qry);
    if ($arr.count > 0)


  where did you get that $arr.count thingie?
  you can count the result rows with mysql_num_rows
