SQL在单个查询中更新多行

Question

如果让我说我想在单个SQL查询中更新2行或更多行，我该怎么办呢？我目前的陈述不起作用如下：

UPDATE PricePlan SET Price='" + GuestInput.Text + "' WHERE PricePlanName = 'Guest' THEN Price='" + MemberInput.Text + "' WHERE PricePlanName = 'Member'

这样的东西应该有用......你需要稍微修改一下

"UPDATE PricePlan 
       SET price =
                 IIf(PricePlanName = 'Guest',"+ GuestInput.Text + ",
                   IIf(PricePlanName = 'Member',"+ MemberInput +"))"
