Why is this failing? I am connected to the correct db, and keys is definitely there.

//verify key against key list in database
if ($prep_statement = $db->prepare("SELECT id FROM key_list WHERE keys=?"))
{
    $prep_statement->bind_param('s',$key);
    $prep_statement->execute();
    echo $prep_statement->num_rows;
     $prep_statement->close();
} else {
    printf("Prepared Statement Error: %s\n", $db->error); 
    die();      
}

I get the following error, and the if statement is returning false

Prepared Statement Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'key=?' at line 1 

Here's my table structure:

A: 

Somehow your query must not match your database. Can you paste the structure of your table?

I've included my db structure in the original post.

A: 

You are binding a result, not binding a parameter. Change bind_result to bind_param and it should work correctly.


key is a MySQL reserved word. You'll need to either change the column name to something that is not a reserved word, or you'll need to quote it. In MySQL, the default identifier quote character is the backtick, `, though if ANSI Quotes are enabled, you can use the double quote, ", instead.

So, your statement should be:

SELECT id FROM key_list WHERE `key` = ?

I've corrected my code. Same error. Updated original post.
Eric
A-ha, I didn't notice before, but you're using a reserved word. Answer updated.
Charles
Works now. I tried both key and keys, but apparently they're both reserved. Thanks!!
