PHP Help Needed

I have a table in my database named clerk_names. In this database there is a colum named active & by default they are all set to 0. Will this code mark all the entries in the active columnn to 1?

<?phprequire('connection.php');$query="UPDATE clerk_names SET active = '1' ";?>

Open in new window


Basically, I will be calling this script from a web page & when it is called I need it to mark all the 0's in active field to 1. There are only 10 entries in the active field. Thanks for any help provided.

The answer from looking at the code is no.
<?php require('connection.php');$query="UPDATE clerk_names SET active = '1' ";?>

Open in new window

should be
<?php 
require('connection.php');
$query="UPDATE clerk_names SET active = '1' where active = '0' ";
$result = mysql_query($query) or die("There was an error");
?>

That code will update every record in your table setting active to 1.

If you wish to mark all 0's to 1's, do this instead;

$query="UPDATE clerk_names SET active = '1'  where active = '0'";

It matters if the only two possible values in that field are 0 and 1.

What you wrote will set ALL values in that column to 1 regardless of what is there.

If you want to change only the 0's to 1's, then use what adrian_brooks and roads_roads gave you.

If there are other possible values, including blanks for example, you might need more decision making in your query.
