使用子查询连接进行Mysql更新

Question

我有更新查询：

UPDATE cash_billings_bills_articles 
    SET cash_billings_bills_articles.cashbillingbillarticle_cost = (SELECT articles_pricehistory.articlepricehistory_cost
                                            FROM articles_pricehistory
                                            LEFT JOIN cash_billings_bills
                                                 ON cash_billings_bills_articles.cashbillingbill_id = cash_billings_bills.cashbillingbill_id
                                            WHERE articles_pricehistory.article_id = cash_billings_bills_articles.article_id AND
                                                 articles_pricehistory.articlepricehistory_date <= cash_billings_bills.cashbillingbill_date
                                            ORDER BY articles_pricehistory.articlepricehistory_date DESC
                                            LIMIT 1
                                           );

但是我得到了错误：Error Code: 1054. Unknown column 'cash_billings_bills_articles.cashbillingbill_id' in 'on clauseError Code: 1054. Unknown column 'cash_billings_bills_articles.cashbillingbill_id' in 'on clause' 0.000 sec

更新表格结构：

Answer 1

您的加入条件似乎是错误的。在您的查询中，您尝试在条件

的情况下加入表格articles_pricehistory和cash_billings_bills

cash_billings_bills_articles.cashbillingbill_id = cash_billings_bills.cashbillingbill_id

其中cash_billings_bills.cashbillingbill_id列应与articles_pricehistory表而不是cash_billings_bills_articles表的某些列进行比较。

您的查询应该更像

UPDATE cash_billings_bills_articles 
SET 
    cash_billings_bills_articles.cashbillingbillarticle_cost = (SELECT 
            articles_pricehistory.articlepricehistory_cost
        FROM
            articles_pricehistory
                LEFT JOIN
            cash_billings_bills_articles ON cash_billings_bills_articles.article_id = articles_pricehistory.article_id
                LEFT JOIN
            cash_billings_bills ON cash_billings_bills_articles.cashbillingbill_id = cash_billings_bills.cashbillingbill_id
        WHERE
            articles_pricehistory.articlepricehistory_date <= cash_billings_bills.cashbillingbill_date
        ORDER BY articles_pricehistory.articlepricehistory_date DESC
        LIMIT 1)
