外交部 更新查询
原标题:Advanced SQL Update query

我试图为一种储存程序制造一个 s更新的问询,但我却在试图弄清如何这样做时消失。

这就是我试图做的事情:

表格Im希望更新有3栏:产品_项目_id, rel_product_item_id, 和序列。 该表称为“教育”。

我还有另一个表格,称为产品细目。 本表还包含一个名为“产品”的栏目——项目——以及一个称为“库”的栏目。

I want the user to be able input the sku number that updates the rel_product_item_id column with the corresponding product_item_id number from the ProductDetails table.

因此,在前端,用户正在输入一个库,但在后端,产品——项目号——正在数据库中根据输入的用户库进行更新。

基本上,在细节表上对库号进行交叉参照,发现近似产品件数,在表格中添加该数字,而不是用户投入的库数。
