SQL Server更新聲明

Question

我想給表中的值客戶設置狀態=「A」在一個個人上

如何查詢哪些表的mastersales與表Customer相關？

屬性和值MasterSales

例公司：ABC公司（MS001）

mastersales : ms001 (primarykey) 
Customer : cu0112, cu113,cu114,cu116,cu117 

mastersales : ms002 (primarykey) 
Customer : cu0115 

，所以我想更新顧客設置狀態= 'A'，其中客戶= mastersales ms001 (cu0112, cu113,cu114,cu116,cu117)

Answer 1

update tablename set status = 'A' where customer in (select customer from tablename where mastersales =ms001); 

Answer 2

試試這個：

UPDATE c 
    SET status = 'A' 
    FROM Customer c 
    INNER JOIN Mastersales m ON c.customer = m.customer 
    WHERE m.mastersales = 'ms001';
