VB.net如何在單個sql代碼中更新2列

Question

我想同時更新狀態並在房間表中確認用戶ID，我可以用單個sql代碼執行還是應該拆分出來？ 怎么樣？

       sql = "update room set status = '" & status & "' and set confirmstudentid= " & Form1.stuID & "where id=" & lblroomID.Text & ";"

Answer 1

請嘗試以下方法；

sql = "update room set status = '" & status & "' , confirmstudentid = " & 
       Form1.stuID & " where id= " & lblroomID.Text & ";"

您只需要用逗號分隔各列,而不用添加另一set
