を使用して、次のクエリを実行中にエラー私はこれは少しシンプルに見えます知っているが、このクエリを実行しながら、私はこのエラーを取得されています。このクエリで

SELECT 'NOC Service Request Acknowledgement - All severities' AS [Problem_Type_Name(Parent) Category] 
,[Job_ticket_id] 
,CASE WHEN (case when [Escalated to Resolved time] is null then (ISNULL([Escalated to Resolved time],0) + ISNULL([Escalated to Closed time],0)- ISNULL([hold time],0)) else (ISNULL([Escalated to Closed time],0) - ISNULL([hold time],0)) end) <0THEN 0 ELSE (case when [Escalated to Resolved time] is null then (ISNULL([Escalated to Resolved time],0) + ISNULL([Escalated to Closed time],0)- ISNULL([hold time],0)) else (ISNULL([Escalated to Closed time],0) - ISNULL([hold time],0)) end) END AS JobTime

WHERE [Problem_Type_Name(Parent) Category] IN ('NOC Service Request Acknowledgement - Urgent','NOC Service Request Acknowledgement - High',
