Question

嗨，我的SQL出现了新问题...

我尝试更新在我的商店商店中分配给特定类别的所有文章。

我为此建立了一个查询：

update s_articles_prices
INNER JOIN s_articles on s_articles_prices.articleID=s_articles.id
INNER JOIN s_articles_supplier on s_articles.supplierID=s_articles_supplier.id
INNER JOIN s_articles_details on s_articles.id=s_articles_details.articleID
SET price = price + 10
WHERE s_articles_supplier.name="category name"

现在我想知道我的查询更新了哪些值...

我也有一个选择查询，是否可以将这两个查询连接起来以准确显示我的更新查询更新了它们的表？

这是我的选择：

SELECT s_articles.id as aid, s_articles.name as aName, s_articles.supplierID as sID, s_articles_prices.pricegroup as pricegroup, s_articles_prices.price as price, s_articles_supplier.name as sName, s_articles_details.ordernumber as sku
FROM s_articles
INNER JOIN s_articles_prices on s_articles.id=s_articles_prices.articleID
INNER JOIN s_articles_supplier on s_articles.supplierID=s_articles_supplier.id
INNER JOIN s_articles_details on s_articles.id=s_articles_details.articleID
WHERE s_articles_supplier.name="category name"

我希望现在具有与选择类似的输出，以便我可以一目了然地检查我的更新是否有效

谢谢您的时间：）

在DiarSelimi和RaymondNijland的帮助下，我得以解决了我的问题。

我现在已经这样：

我已经用以下部分创建了一个sql脚本：

创建一个临时表：

CREATE TEMPORARY TABLE snapTable 
SELECT s_articles.id as aid, s_articles.name as aName, s_articles.supplierID as sID, s_articles_prices.pricegroup as pricegroup, s_articles_prices.price as price, s_articles_supplier.name as sName, s_articles_details.ordernumber as sku
FROM s_articles
INNER JOIN s_articles_prices on s_articles.id=s_articles_prices.articleID
INNER JOIN s_articles_supplier on s_articles.supplierID=s_articles_supplier.id
INNER JOIN s_articles_details on s_articles.id=s_articles_details.articleID
WHERE s_articles_supplier.name="category name";

运行我的更新：

update s_articles_prices 
INNER JOIN s_articles on s_articles_prices.articleID=s_articles.id 
INNER JOIN s_articles_supplier on s_articles.supplierID=s_articles_supplier.id 
INNER JOIN s_articles_details on s_articles.id=s_articles_details.articleID 
SET price = price + 10 
WHERE s_articles_supplier.name="category name";

并将我的临时表与实时表进行比较：

SELECT aid, sku, snapTable.price, s_articles_prices.price as newPrice 
FROM snapTable
INNER JOIN s_articles on snapTable.aid=s_articles.id
INNER JOIN s_articles_prices on snapTable.aid=s_articles_prices.articleID;

您将得到类似的内容：

aid|sku     |price            |newPrice
-------------------------------------------------
2  |number  |202.60504201681  |212.60504201681
2  |number  |202.60504201681  |212.26050420167996

也许对其他人也有帮助：）
