Question

我正在尝试在我的选择中创建“Buckets”。基本上我想确定记录的老化（在这种情况下是票证）。老龄化取决于2个领域。如果存在所需日期，则它基于此字段，如果没有要求日期，则基于输入故障单的日期。我想要达到的目标是在120 +，90-120天，60-90天，30-60天，15-30天，5-15天和1-5天内使用老化桶。
以下查询无法正常工作（语法错误）。我现在已经盯着它看了太长时间。

编辑格式化

尝试整理代码，例如

WITH source_date AS (
    SELECT
       v_rpt_Service.TicketNbr,
       v_rpt_Service.Location,
       v_rpt_Service.Board_Name,
       v_rpt_Service.Status_Description,
       v_rpt_Service.ClosedDesc,
       v_rpt_Service.ServiceType,
       v_rpt_Service.SubType_RecID,
       v_rpt_Service.ServiceSubType,
       v_rpt_Service.company_name,
       v_rpt_Service.Summary,
       v_rpt_Service.team_name,
