这里的正确语法是什么?
If (@timestamp < (Select PromoStartTimestamp From @promo)) RAISERROR('Code not valid until ' + (Select PromoStartTimestamp From @promo),16,1); 我试过了: If (@timestamp < (Select PromoStartTimestamp From @promo)) RAISERROR(N'Code not valid until @starttimestamp',1,(Select PromoStartTimestamp From @promo)); Michael Fredrickson的回答让我在“CAST”附近出现错误的语法错误. 解决方法您可以在RAISERROR 中使用%s作为字符串替换参数:
DECLARE @PromoStartTimestamp DATETIME DECLARE @PromoStartTimestampString VARCHAR(50) SELECT @PromoStartTimestamp = PromoStartTimestamp From @promo SELECT @PromoStartTimestampString = CAST(@PromoStartTimestamp AS VARCHAR) If (@timestamp < @PromoStartTimestamp) RAISERROR(N'Code not valid until %s',@PromoStartTimestampString); (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
