Question

首先让我先说我是mysql的新手。我正在从转储数据转换到excel并从那里使用voodoo，所以这种新语言可能令人困惑，但我正在处理简单的查询。

我无法找到答案的第一个问题是，我正在寻找可计费的医疗遭遇，然后将它们与在该时间段内看到的患者数量进行比较。（编辑：这是我在这里遇到问题的“CASE WHEN声明”

可结算遭遇由唯一遭遇计算，可以将该遭遇的任意数量的可计费代码之一计为可计费。（还有更多的代码，但我为空间而截断）

这就是我迄今为止所做的事情当然不起作用：

SELECT                   
            CONCAT(`users`.`ulname`,', ',`users`.`ufname`) AS Provider              
                      , YEAR(e.`date`) AS 'YEAR'
                      , LEFT(MONTHNAME(e.date), 3) AS 'MONTH' 
                      , COUNT(DISTINCT e.`patientID`) AS Pts
                      , COUNT(DISTINCT e.`encounterID` CASE WHEN d.`value` 
IN ('99213','99214','99212','99203','99202','90832','99393') THEN END AS 
Bill_Encs
                      , COUNT(e.`status`) AS 'Vts_CHK' 
                      , COUNT(e.`status`) - COUNT(DISTINCT e.`encounterID`) 
AS No_Codes

FROM enc e 
    INNER JOIN `mobiledoc`.`users` ON `users`.`uid` = e.`ResourceId`                
            INNER JOIN `billingdata` billing ON billing.`EncounterId` = 
e.`encounterID`
            INNER JOIN items i ON i.`itemID` = billing.`itemID`
            INNER JOIN `itemdetail` d ON d.`itemID` = i.`itemID`
 WHERE e.`date` BETWEEN CAST('2017-10-26' AS DATE) AND CAST('2017-10-31' AS 
DATE)
            AND d.`propID` = 13
            AND billing.`deleteFlag` = 0
            AND i.`deleteFlag` = 0         
            AND e.status = "CHK"
            AND e.`deleteFlag` = 0
            AND e.`encType` = 1
            AND e.`ClaimReq` = 1
            AND `users`.`UserType` = 1                                               


 GROUP BY Provider ASC, YEAR(e.`date`) ,MONTH(e.`date`) ASC;

Answer 1

如果所有其他方面都相同（正常），我认为你只想要条件聚合。

, COUNT(DISTINCT e.`encounterID` CASE WHEN d.`value` 
IN ('99213','99214','99212','99203','99202','90832','99393') THEN END AS 
Bill_Encs

变为

, COUNT(DISTINCT CASE WHEN d.`value` 
IN ('99213','99214','99212','99203','99202','90832','99393') THEN e.`encounterID` END AS Bill_Encs

使用案例时计算明显不同
