我有一個功能，我不喜歡，功能從表中刪除產品。將多個刪除查詢組合成更少？
這也會刪除該產品的所有類別，標籤和變體， ，並且對於每個變體刪除其所有圖像，文檔和值。
這歸結爲兩個選擇查詢和六個刪除查詢。
有沒有辦法讓這個數據庫密集程度降低？
delete from $this->table where id = $id
delete from $this->clink where product_id = $id
delete from $this->tlink where product_id = $id
$variants = select id from $this->vlink where product_id = $id //e.g. (1,2)
delete from $this->vlink where product_id = $id
delete from cart_variant_values where variant_id in $variants
delete from cart_variant_images where variant_id in $variants
delete from cart_variant_documents where variant_id in $variants
我希望我可以做這樣的事情：
variants = select id from $this->vlink where product_id = $id //e.g. (1,2)
delete from $this->table where id = $id
delete from $this->clink, $this->tlink, $this->vlink where product_id = $id
delete from cart_variant_values, cart_variant_images, cart_variant_documents
where variant_id in $variants
但顯然還是不行！
編輯（2012年11月21日）：
將這項工作？
DELETE vi, vv, vd, v, p, pc, pt
FROM cart_variant_images vi
INNER JOIN cart_variant_values vv
INNER JOIN cart_variant_documents vd
INNER JOIN cart_product_variants v ON vd.variant_id = v.id
INNER JOIN cart_products p ON v.product_id = p.id
INNER JOIN cart_products_categories pc ON p.id = pc.product_id
INNER JOIN cart_products_tags pt ON p.id = pt.product_id
WHERE p.id = $id;
該查詢拋出我沒有錯誤，但我想知道它是否會做我想要的？
請注意，每個表中將有不同數量的行，那麼內部連接是否正確連接？
