VB.net如何在单个sql代码中更新2列

Question

我想同时更新状态并在房间表中确认用户ID，我可以用单个sql代码执行还是应该拆分出来？ 怎么样？

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

Answer 1

请尝试以下方法；

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

您只需要用逗号分隔各列,而不用添加另一set
