SQL-LEAD函数

问题描述

我尝试使用以下代码:

 SELECT SkillTargetID,DateTime,lead(EventName,1) over (partition by EventName order by DateTime) as next_eventname,lead(ReasonCode,1) over (partition by ReasonCode order by DateTime) as next_ReasonCode
 FROM ucce1_awdb.dbo.Agent_State_Trace ast
 WHERE 
 EventName = 3 and
 ReasonCode= 0 and
 next_eventname = 0 and
 next_ReasonCode = 114

但是由于next_eventnamenext_ReasonCode,我无法执行该查询。有人可以建议我该如何处理吗?
