sql-server - SQL 抛出算术溢出错误

Question

我在运行简单的聚合函数时收到“算术溢出错误将表达式转换为数据类型 int”错误(请参阅下面的代码)。当我缩减日期范围时，我可以看到结果实际上超过了 INT 数据类型限制......我已经尝试将整个表达式转换为 BIGINT，但没有成功。有人知道我该如何解决这个问题吗？

所有这 3 个查询都会抛出上述相同的错误:

Select  (SUM(ACDTalkTimeInSec) + SUM(TotAcwTimeInSec) + SUM(HoldTimeInSec)) as AHT
From ColTelephony.dbo.vwACDSkillCombined acd
Where WorkDte between '1/2/2018' AND '10/5/2018'

Select  CAST(Cast(SUM(ACDTalkTimeInSec) AS BIGINT) + CAST(SUM(TotAcwTimeInSec) AS BIGINT) + CAST(SUM(HoldTimeInSec) AS BIGINT) AS BIGINT) as AHT
From ColTelephony.dbo.vwACDSkillCombined acd
Where WorkDte between '1/2/2018' AND '10/5/2018'

Select  Cast(((SUM(ACDTalkTimeInSec) + SUM(TotAcwTimeInSec) + SUM(HoldTimeInSec))) AS BIGINT) as AHT
From ColTelephony.dbo.vwACDSkillCombined acd
Where WorkDte between '1/2/2018' AND '10/5/2018'

Answer 1

SMor 在评论中回答了它，但这里是 sql:

Select SUM(CAST(ACDTalkTimeInSec AS BIGINT)) + SUM(CAST(TotAcwTimeInSec AS BIGINT)) 
    + SUM(CAST(HoldTimeInSec AS BIGINT)) as AHT
From ColTelephony.dbo.vwACDSkillCombined acd
Where WorkDte between '1/2/2018' AND '10/5/2018'

如果 SMor 发布了他们的答案，则接受它。我没有测试代码，所以请原谅任何拼写错误。
