对postgresql查询中同一表中的两列值求和 选择c.period， c、 idsr\u事件\u id\u id， c、 idsr_疾病_id_id， 当idsr\u事件\u id\u id=1或idsr\u事件\u id\u id=3，然后求和（c.data\u value:：integer），否则0作为案例结束， 当idsr\u事件\u id\u id=2或idsr\u事件\u id\u id=4，然后求和（c.data\u value:：integer），否则0以死亡结束 来自veoc_idsr_周报_国家报告c 在b.id=c.idsr\u disease\u id\u id上左键连接veoc\u idsr\u diseases b 左连接veoc_idsr_报告的_事件j ON j.id=c.idsr_事件_id_id 如果c.idsr\u事件\u id>=1和c.idsr\u事件\u id\u id

请尝试以下查询，其中替换了函数位置之和：

SELECT c.period,
    c.idsr_incident_id_id,
    c.idsr_disease_id_id,
    CASE WHEN idsr_incident_id_id = 1 OR idsr_incident_id_id = 3 THEN SUM(c.data_value::integer) ELSE 0 END  AS cases,
    CASE WHEN idsr_incident_id_id = 2 OR idsr_incident_id_id = 4 THEN SUM(c.data_value::integer) ELSE 0 END  AS deaths
   FROM veoc_idsr_weekly_national_report c
     LEFT JOIN veoc_idsr_diseases b ON b.id = c.idsr_disease_id_id
     LEFT JOIN veoc_idsr_reported_incidents j ON j.id = c.idsr_incident_id_id
    WHERE c.idsr_incident_id_id >= 1 AND c.idsr_incident_id_id <= 4 AND idsr_disease_id_id = 10 AND period ='2019W30'
  GROUP BY c.period, c.idsr_incident_id_id, c.idsr_disease_id_id, c.data_value;`enter code here`

选择c.period，
c、 idsr_疾病_id_id，
求和（当idsr\U事件id\U id=1或idsr\U事件id\U id=3时的情况，然后（c.data\U value:：integer）否则为0结束）作为情况，
总和（当idsr\U事件id\U id=2或idsr\U事件id\U id=4时，则为（c.data\u value:：integer），否则为0结束）作为死亡

在b.id=c.idsr\u disease\u id\u id上左键连接veoc\u idsr\u diseases b
左连接veoc_idsr_报告的_事件j ON j.id=c.idsr_事件_id_id
