Well, if you stop to think about this for a second, it may occur to you to wonder how MySQL is supposed to tell the difference between the column name id-sys, and the expression id-sys (i.e. the value of the id column minus the value of the sys column). The answer is that you have to demarcate a column name like this that is ambiguous -- and in MySQL that's with ` back ticks. (Other databases have other means of doing this -- or just restrict column names to avoid the issue!) Cheers!

Note that those are not single quotes, they are backticks, to the left of the number 1 key. ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP-DB] Update Query Help...
I have definitely isolated the problem. If I change the column name that the match is being performed on from 'id-sys' to 'id_sys' I can execute the query without having to worry about quoting the column name and everything works. I think that I am just going to leave the column name changed and take this as a lesson never to use '-' in a column name again. Thanks again for the help. Maybe we all learned something from this. -Original Message- From: DL Neil [mailto:[EMAIL PROTECTED]] Sent: Tuesday, December 10, 2002 2:00 PM To: NIPP, SCOTT V (SBCSI); '1LT John W.

RE: [PHP-DB] Update Query Help...
I understand that the column name does not normally need quotes, but without quotes on the column name I get a mysql error message about no column named 'id'. Unfortunately, I cannot even get the UPDATE statement working outside of PHP through an direct SQL statement. Everything looks like it should work, but the affected columns is always zero, and obviously the atime column is not getting the timestamp. This is quite frustrating. Thanks again for the help. Hopefully someone will come up with something to help me get this working. -Original Message- From: 1LT John W.

RE: [PHP-DB] Update Query Help...
is it a mysql field type of datetime?
if so, you may want to use this instead
$timestamp=date("Y-m-j H:i:s");
$update = "UPDATE accounts SET atime='$timestamp' WHERE id-sys='$tmp'";
that puts the current timestamp in mysql format for entry into your table.
Cheers

I am attempting to UPDATE a table and I have having absolutely ZERO
success. Here is the query:
$tmp = $_POST['sbcuid']."-".$_POST['system'][$a];
$update = "UPDATE accounts SET atime='NOW()' WHERE
\"id-sys\"='".$tmp."'";
echo $update;
$result1 = mysql_query($update, $Prod) or die(mysql_error());
echo mysql_affected_rows();
Please help me figure out why this is not working. I have tried
quoting the column name 'id-sys' every way I can think of, but nothing
works. The column is initially NULL, and I am attempting to update just the
single column with a timestamp. Thanks in advance.
