如何将 sql 列值汇总到一个单独的列中？ 在这里总结 NPM,NPF,NPC 到一个新的专栏

Question

SELECT DATE_FORMAT(e.`date_created`,'%d-%b-%Y') AS DATE,
       SUM(CASE WHEN ps.Gender = 'M'
           AND e.encounter_type<='6'
           AND DATEDIFF(CURDATE(), ps.birthdate)>4381 THEN 1 ELSE 0 END) AS **NPM**,
       SUM(CASE WHEN ps.Gender = 'F'
                 AND e.encounter_type<='6'
                 AND DATEDIFF(CURDATE(), ps.birthdate)>4381 
                THEN 1 ELSE 0 END) AS **NPF**,
       SUM(CASE WHEN DATEDIFF(CURDATE(), ps.birthdate)<=4380
                 AND e.encounter_type<='6' 
                THEN 1 ELSE 0 END) AS **NPC**,
SUM(CASE WHEN ps.Gender = 'M'
    AND e.encounter_type>'6'
    AND DATEDIFF(CURDATE(), ps.birthdate)>4381 THEN 1 ELSE 0 END) AS OPM,
SUM(CASE WHEN ps.Gender = 'F'

    AND DATEDIFF(CURDATE(), ps.birthdate)>4381 THEN 1 ELSE 0 END) AS OPF,
SUM(CASE WHEN DATEDIFF(CURDATE(), ps.birthdate)<=4380

GROUP BY DATE_FORMAT(e.`date_created`,'%Y-%m-%d')

正如您所说，您的查询正在运行，您只需要将其包装为子查询并将这三列求和如下

旁注： DATE是一个保留字，所以你需要反引号。

SELECT `DATE`,
        NPM+NPF+NPC AS SUM_TREE_COLS,
        OPM,
        OPF,
        OPC,
        total
 FROM (
   SELECT DATE_FORMAT(e.`date_created`,'%d-%b-%Y') AS `DATE`,
          SUM(CASE WHEN ps.Gender = 'M'
              AND e.encounter_type<='6'
              AND DATEDIFF(CURDATE(), ps.birthdate)>4381 THEN 1 ELSE 0 END) AS NPM,
          SUM(CASE WHEN ps.Gender = 'F'
                    AND e.encounter_type<='6'
                    AND DATEDIFF(CURDATE(), ps.birthdate)>4381 
                   THEN 1 ELSE 0 END) AS NPF,
          SUM(CASE WHEN DATEDIFF(CURDATE(), ps.birthdate)<=4380
                    AND e.encounter_type<='6' 
                   THEN 1 ELSE 0 END) AS NPC,
   SUM(CASE WHEN ps.Gender = 'M'
       AND e.encounter_type>'6'
       AND DATEDIFF(CURDATE(), ps.birthdate)>4381 THEN 1 ELSE 0 END) AS OPM,
   SUM(CASE WHEN ps.Gender = 'F'
       AND e.encounter_type>'6'
       AND DATEDIFF(CURDATE(), ps.birthdate)>4381 THEN 1 ELSE 0 END) AS OPF,
   SUM(CASE WHEN DATEDIFF(CURDATE(), ps.birthdate)<=4380
       AND e.encounter_type>'6' THEN 1 ELSE 0 END) AS OPC,
   COUNT(e.`patient_id`) AS total
   FROM patient_search ps
   LEFT JOIN
   (SELECT e.`encounter_id`,
           e.`encounter_type`,
           e.`patient_id`,

    WHERE oo.`concept_id`='4086')AS eId ON e.`encounter_id`=eId.encounter_id
   GROUP BY DATE_FORMAT(e.`date_created`,'%Y-%m-%d')
