Question

执行此SQL查询时，我收到以下区域消息：

关键字'else'
附近的语法不正确

以下是查询：

SELECT
    *,
    CASE 
        WHEN los IN (0, 1, 2, 3, 4) THEN 'under 5'
        WHEN los >= 5 THEN 'above 5'
        ELSE 'Unknown' 
    END AS los_type
FROM
    (SELECT 
         CASE
            WHEN LEN(comp.AGTNUMBER) = 6 THEN substring(comp.AGTNUMBER, 2, 5) 
            ELSE comp.AGTNUMBER 
         END AS FR_Number,
         comp.COMPLAINTNUMBER,
         YEAR(comp.opendate) AS Comp_Year,
         comp.COMPLAINTORIGIN,
         comp.COMPTYPE AS Comp_Type,
         comp.OPENDATE,
         comp.REBUTTAL,
         comp.AGENTNAMEINCOM,
         CASE
            WHEN fr.FULL_TIME_SVC_DTE < comp.OPENDATE 
               THEN FLOOR(DATEDIFF(MONTH, fr.FULL_TIME_SVC_DTE, comp.OPENDATE) / 12)
            WHEN fr.FULL_TIME_SVC_DTE > comp.OPENDATE 
               THEN floor(datediff(month, fr.ACTUAL_CONTRACT_END_DATE, fr.FULL_TIME_SVC_DTE) / 12
            ELSE NULL 
        END AS los
     FROM 
         dbo.EC_Complaints_Info AS comp
     LEFT JOIN
         dbo.FLD_REP_Info AS fr 
             ON CASE WHEN LEN(comp.AGTNUMBER) = 6 
                       THEN substring(comp.AGTNUMBER, 2, 5) 
                    ELSE comp.AGTNUMBER 
               END = fr.FR_NUMBER
             AND comp.OPENDATE BETWEEN fr.ACTUAL_CONTRACT_START_DATE 
                                   AND fr.ACTUAL_CONTRACT_END_DATE
     WHERE
        ((comp.REBUTTAL = 'No'))
        AND ((comp.STATUS = 'open') OR
             (comp.STATUS = 'closed'))
 ) AS a

任何人都可以帮我弄清楚为什么我收到此错误消息？

您遗失了)个CASE表达式中的case when fr.FULL_TIME_SVC_DTE < comp.OPENDATE then floor(datediff(month, fr.FULL_TIME_SVC_DTE, comp.OPENDATE)/12) when fr.FULL_TIME_SVC_DTE > comp.OPENDATE then floor(datediff(month, fr.ACTUAL_CONTRACT_END_DATE, fr.FULL_TIME_SVC_DTE)/12 --here is the error else null end as los：

case when fr.FULL_TIME_SVC_DTE < comp.OPENDATE then floor(datediff(month, fr.FULL_TIME_SVC_DTE, comp.OPENDATE)/12)
       when fr.FULL_TIME_SVC_DTE > comp.OPENDATE 
       then floor(datediff(month, fr.ACTUAL_CONTRACT_END_DATE, fr.FULL_TIME_SVC_DTE)/12)
                         else null end as los

应该是：

rabbitmq-server start

sbin/service rabbitmq-server start

运行SQL命令时，关键字'else'附近的语法不正确
