Wrap div if MYSQL column same - php

Question

I've created a pretty standard output script that spits out a list from my database WHERE bv_category="Smart" and they are also ordered by subcategory+id.
All is well and good, but I'd like to further enhance this by splitting this up into separate divs so as to provide more grouping -- "visually". It's a pretty standard table at this point.
So for those with the same bv_subcategory would be placed into a separate div container. I'd style accordingly each one. Any tips on achieving this?
I tried an if within the for each, but that would insert a div for each one where as I'd want to wrap each one that has the same bv_subcategory value.
$query = "SELECT * FROM wp_products_table_ba_BV_unique";
if (! empty ( $sql_filter )) {
$query .= ' WHERE bv_category="Smart" AND ' . implode ( ' AND ', $sql_filter ) . ' ORDER BY bv_subcategory ASC, id ASC';
}
else {
$query = "SELECT * FROM wp_products_table_ba_BV_unique WHERE bv_category='Smart' ORDER BY bv_subcategory ASC, id ASC";
}
echo "SQL been Called : <br/>";
echo "<b>" . $query . "</b>";
$products = $wpdb->get_results ( $query );
$prodTable_Build = "<table id='myTable' class='display' cellspacing='0' width='100%'>";
$prodTable_Build .= "<thead class='productTableHead'>

$bv_product_iw_bulk = stripslashes ($product->bv_product_iw_bulk);

You get the idea
$query = "SELECT * FROM ORDER BY `bv_subcategory`";
$temp = row['bv_subCategory'];
<div>
//in loop
if($temp != row['bv_subcategory'])
{
echo "</div><div>"
$temp = $row['bv_subcategory'];
}
//after loop
</div>
