update datastore from cron?? possible?

[rob30UK]

I have set up the following code to update the datastore every 12 hours.
The code I've used pulls a few fields from a custom table but its not updating the datastore.

Is this code right or do i need to include a file or something?

<?php
$rsqry = $db->query_read('SELECT threadid, keywords FROM glossary_links');

while($variable = $db->fetch_array($rsqry))
{
$variable_array[] = $variable;
}

build_datastore('glossary_links', serialize($variable_array));
?>
