You can use %sas a string substitution parameter in RAISERROR:
您可以%s在RAISERROR以下内容中用作字符串替换参数：
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'
,16
,1
,@PromoStartTimestampString);
