wpdb select query to get certain meta_key? - sql

Question

I have the below code where I am trying to get a list of orders.
So from the wcomm (woocommerce_order_itemmeta) table, I only want to display the meta_value where the meta_key is equal to _qty or _product_id and I need the _product_id to be filtered on a single value like I have. I can't seem to make it only do both things.. My output never shows the _qty value because I'm specifically filtering the value of _product_id but I don't understand what to change
global $wpdb;
$wpdb->woocommerce_order_items = $wpdb->prefix . 'woocommerce_order_items';
$wpdb->woocommerce_order_itemmeta = $wpdb->prefix . 'woocommerce_order_itemmeta';
$uvuorderposts = $wpdb->get_results(
"
SELECT p.ID, p.post_title, p.post_date, wcom.order_item_name, wcomm.meta_key, wcomm.meta_value
FROM $wpdb->posts AS p
INNER JOIN $wpdb->postmeta AS pm ON p.ID = pm.post_id
INNER JOIN $wpdb->woocommerce_order_items AS wcom ON p.ID = wcom.order_id
INNER JOIN $wpdb->woocommerce_order_itemmeta AS wcomm ON wcom.order_item_id = wcomm.order_item_id
WHERE (p.post_type = 'shop_order')
AND (pm.meta_key = '_wc_authorize_net_aim_charge_captured')
AND (pm.meta_value = 'yes')
AND (wcomm.meta_key = '_product_id')
OR (wcomm.meta_key = '_qty')
AND (wcomm.meta_value = '2193')
ORDER BY p.post_date
"
);
echo "<table>";
foreach ( $uvuorderposts as $uvuorderpost )
{
echo "<tr><td>" . $uvuorderpost->post_title . " - " . $uvuorderpost->ID . "</td><td>" . $uvuorderpost->post_date . "</td><td>" . $uvuorderpost->meta_key . ": " . $uvuorderpost->meta_value . "</td></tr>";
echo "<tr bgcolor='#eaeaea'><td colspan='3'>" . $uvuorderpost->order_item_name . "</td></tr>";
}
echo "</table>";
I tried to "filter" it on the output by using $uvuorderpost->meta_key['_qty'] but it did not work!

Answer 1

I fixed it with the following changes. Just joined that table twice and it works now. Not sure if it's best practice but yeah
global $wpdb;
$wpdb->woocommerce_order_items = $wpdb->prefix . 'woocommerce_order_items';
$wpdb->woocommerce_order_itemmeta = $wpdb->prefix . 'woocommerce_order_itemmeta';
$uvuorderposts = $wpdb->get_results(
"
SELECT p.ID, p.post_title, p.post_date, wcom.order_item_name, wcomm.meta_key, wcomm.meta_value, wcomm2.meta_key AS meta_key_qty, wcomm2.meta_value AS meta_value_qty
FROM $wpdb->posts AS p
INNER JOIN $wpdb->postmeta AS pm ON p.ID = pm.post_id
INNER JOIN $wpdb->woocommerce_order_items AS wcom ON p.ID = wcom.order_id
INNER JOIN $wpdb->woocommerce_order_itemmeta AS wcomm ON wcom.order_item_id = wcomm.order_item_id
INNER JOIN $wpdb->woocommerce_order_itemmeta AS wcomm2 ON wcom.order_item_id = wcomm2.order_item_id
WHERE (p.post_type = 'shop_order')
AND (pm.meta_key = '_wc_authorize_net_aim_charge_captured')
AND (pm.meta_value = 'yes')
AND (wcomm.meta_key = '_product_id')
AND (wcomm.meta_value = '2193')
AND (wcomm2.meta_key = '_qty')
ORDER BY p.post_date
"
);
echo "<table>";
foreach ( $uvuorderposts as $uvuorderpost )
{
echo "<tr><td>" . $uvuorderpost->post_title . " - " . $uvuorderpost->ID . "</td><td>" . $uvuorderpost->post_date . "</td></tr>";
echo "<tr bgcolor='#eaeaea'><td colspan='2'>" . $uvuorderpost->order_item_name . "</td></tr>";
echo "<tr bgcolor='#eaeaea'><td colspan='2'>" . $uvuorderpost->meta_key . " : " . $uvuorderpost->meta_value . "</td></tr>";
echo "<tr bgcolor='#eaeaea'><td colspan='2'>" . $uvuorderpost->meta_key_qty . " : " . $uvuorderpost->meta_value_qty . "</td></tr>";
}
echo "</table>";
